Window Replacement cost in Dallas, TX
A typical window replacement in Dallas, Texas models at $6,800 – $13,700, with a mid point around $9,500. Dallas carries a labour index of 0.96, a material index of 0.99 and a permit index of 0.9 against the national base, in climate zone 2A with a 6 in frost depth. That is a whole-job model — 6 scoped tasks, 28 days elapsed, 25% contractor overhead and profit and 7% contingency — not a per-unit rate multiplied out. Renolume states 88/100 confidence (High confidence) for a standard property here.
Modelled by the Renolume estimating model · engine 2.0.0, data v2026.1 · Last updated . Every figure on this page is produced by the Renolume engine at the stated engine and data version. Nothing is scraped, crowd-sourced or supplied by a contractor, and no figure is edited by hand after the model runs.
What drives window replacement cost in Dallas
Why this job is priced differently in Dallas than anywhere else. Everything below is local: the wage base, the supply chain, the permit regime and the weather the assembly has to survive.
| Local factor | Value used | What it means for your quote |
|---|---|---|
| Labour market | 0.96× national base | Dallas–Fort Worth has one of the largest and most competitive residential trade markets in the country, spread across two urban cores and a very wide suburban ring. Rates are below the national basis and quote quality varies accordingly. |
| Material supply | 0.99× national base | Covers freight distance and local supply depth. It moves less than labour, but it moves. |
| Permit regime | 0.90× national base | Permitting is comparatively fast and inexpensive, but it is administered by a large number of separate municipalities with their own requirements for roofing and exterior replacement. |
| Climate exposure | Zone 2A · frost 6 in | Climate zone 3A on the northern edge of the hot-humid band: long hot summers, high UV, occasional hard freezes and one of the highest hail frequencies of any large US metro. Frost depth is shallow at roughly 6 inches. |
| Wage sample quality | measured | A measured wage sample for CBSA 19100, which is why this city page is published and indexed. |
Hail frequency
Impact-rated assemblies are a mainstream decision here and can affect insurance treatment as well as survival.
Heat and UV
Sustained summer attic temperatures and high UV shorten the life of low-grade materials and make ventilation cost-relevant.
Storm-cycle demand
Prices and lead times move sharply after a hail event, independently of the underlying cost base.
Municipal fragmentation
Dozens of separate authorities across the metroplex, each with their own process and requirements.
Permits, inspections and scheduling in Dallas
Permits, inspections, crew availability and season in Dallas — the part of a project that has nothing to do with the material you pick.
Permitting is comparatively fast and inexpensive, but it is administered by a large number of separate municipalities with their own requirements for roofing and exterior replacement.
Modelled permit allowance for this job: $0 – $400.
Inspection focuses on fastening schedules, wind resistance and, where relevant, impact-rated assemblies. Documentation matters for insurance treatment as much as for the building department.
2 days of inspection wait is modelled inside the 14 days–58 days elapsed window.
Very deep pool, with severe compression after hail. The post-storm influx of out-of-area crews is a recurring local problem and licence verification is essential.
Year-round working season with two constraints: mid-summer surface heat that shortens productive hours, and a spring storm season that drives both damage and demand.
1 day(s) of weather buffer are carried for this metro.
Window Replacement in Dallas: Solar heat gain control is the performance number that pays back here; occasional hard freezes mean the assembly still needs to tolerate cycling, but cooling dominates.
Planning window replacement in Dallas: what local homeowners should know
Planning guidance written for Dallas specifically — the answers change city by city because the labour market, the code regime, the climate and the access conditions do.
The metroplex has a low cost base — plentiful labour, cheap permits, no frost work — and a high-variance market on top of it. What raises a quote is specification rather than geography: impact-rated materials, upgraded fastening for wind, and proper ventilation. What raises it unpredictably is timing, because after a significant hail event the market prices on scarcity rather than cost.
Summer heat cuts productive hours on a roof surface, so warm-month jobs run longer than their nominal duration. The dominant delay, though, is the post-storm queue: after hail, every crew in the region is committed and insurance adjustment adds its own timeline on claim-driven work.
Specify for hail, wind, heat and UV — in that order. Impact classification is the decision with the clearest return in this metro, ventilation is what keeps a heat-loaded assembly alive to its rated life, and solar control is the glazing number that matters because cooling is the season that costs money. Cold-climate detailing is largely irrelevant here.
Autumn through early spring gives full working days, no heat penalty and distance from the spring storm peak. If hail has just passed, waiting is usually the better financial decision unless the assembly is actively failing.
Confirm which municipality you are in, get impact rating quoted explicitly as an option, and check how your insurer treats it. Verify state licensing and a genuine local address before signing — post-storm door-knocking is a persistent problem in this metro — and make sure ventilation scope is written into the quote rather than assumed.
Homeowners are most often surprised by how far the same job's price moves between a quiet month and a post-hail month, and by ventilation deficiencies discovered during a replacement that explain why the previous assembly failed early.
None of this changes the scope of the job — it changes what the job costs and how long it takes here. Model your own window replacement in Dallas to replace these standard-property assumptions with your roof pitch, access, condition and specification, and to raise the confidence score this page reports.
Frame material comparison
Cost, service life, upkeep, efficiency and installation difficulty side by side — the trade-off, not just the price.
| Frame material | Modelled cost | Step up | Rate per window | Elapsed time |
|---|---|---|---|---|
| Vinyl | $6,800 – $13,700 | baseline | $855 – $1,700 | 28 days |
| Fiberglass | $8,500 – $16,600 | +$2,200 | $1,100 – $2,100 | 28 days |
| Wood-clad (wood interior, aluminium or fibreglass exterior) | $11,200 – $21,600 | +$5,800 | $1,400 – $2,700 | 31 days |
| Solid wood | Not modelled yet | — | — | — |
| Aluminium | Not modelled yet | — | — | — |
| Frame material | Service life | Maintenance | Energy | Installation | Planning note |
|---|---|---|---|---|---|
| Vinyl | 20–30 years | None beyond cleaning. Cannot be refinished — colour is the colour. | Good. Multi-chamber frames insulate well; check the whole-unit U-factor, not the glass alone. | Lowest. Widest stock availability and the shortest lead times. | The default for most homes. Large vinyl units can flex and discolour, so watch very wide openings. |
| Fiberglass | 30–50 years | Very low. Paintable, so colour changes are possible later. | Very good. Expansion behaviour close to glass, so seals stay intact longer. | Low, but stock is thinner than vinyl so lead time runs longer. | The best long-hold value in most climates, especially where temperature swings are extreme. |
| Wood-clad (wood interior, aluminium or fibreglass exterior) | 30–50 years | Moderate. The exterior is maintenance-free; the interior wood needs finishing. | Very good. Wood is a natural insulator. | Highest. Made to order, longest lead time, least tolerant of a rushed install. | Chosen for appearance and for historic-district compliance. Order early — lead time drives the schedule. |
| Solid wood | 30+ years with disciplined upkeep | Highest. Requires a repainting or refinishing cycle on both faces. | Very good, provided the frame is maintained and not rotting. | High, and often specified because a historic district requires it. | Usually a conservation requirement rather than a free choice. Confirm before you price alternatives. |
| Aluminium | 30–40 years | Low. Very strong, so it supports the slimmest sightlines. | Weakest unless thermally broken — aluminium conducts heat and can condense in cold climates. | Moderate. Common on large fixed spans and contemporary designs. | Reasonable in mild climates and for oversized glass; a poor choice for a cold-climate whole-home retrofit. |
Solid wood, Aluminium are shown for comparison but do not yet have a Renolume cost model. Renolume will not print a number it cannot derive from its own task and wage data — an invented figure would defeat the point of the confidence score.
Cost by size in Dallas, TX
Every row is a separate run of the same model at the same specification — only the size changes. Note how the per window rate falls as the job grows: fixed costs like permits, mobilisation and disposal setup do not scale with size.
| Number of windows | Typically | Modelled cost | Rate per window | Elapsed time |
|---|---|---|---|---|
| 1 window | a single failed or broken unit | $2,100 – $3,900 | $2,100 – $3,900 | 28 days |
| 5 windows | one elevation, or the rooms you use most | $4,600 – $9,300 | $925 – $1,900 | 28 days |
| 8 windows | a partial whole-home project | $6,800 – $13,700 | $855 – $1,700 | 28 days |
| 12 windows | typical whole-home for a modest house | $9,200 – $18,200 | $763 – $1,500 | 28 days |
| 20 windows | large home, full replacement | $14,300 – $28,300 | $714 – $1,400 | 28 days |
Why window replacement costs what it does in Dallas compared with other metros
Identical scope, identical specification, priced against each metro's own wage sample. Dallas models below the 11-metro average of $9,300 – $11,300, because of low labour and permit base offset by hail-driven specification upgrades and post-storm market volatility.
| Metro | Modelled cost | Labour index | Elapsed time | Why it sits here |
|---|---|---|---|---|
| Houston, TX | $6,700 – $13,400 | 0.93 | 28 days | deep competitive labour pool and the lowest permit burden modelled, offset by wind-resistance scope |
| Atlanta, GA | $6,800 – $13,500 | 0.95 | 28 days | competitive labour, negligible frost work and a moderate permit burden across a highly fragmented jurisdictional map |
| Cleveland, OH | $6,800 – $13,600 | 0.98 | 28 days | labour, material and permit indices all near the national base, with condition risk from older housing stock |
| Dallas, TX (this page) | $6,800 – $13,700 | 0.96 | 28 days | low labour and permit base offset by hail-driven specification upgrades and post-storm market volatility |
| Detroit, MI | $7,000 – $14,000 | 1.02 | 28 days | near-national labour rates carrying genuinely severe cold-climate detailing requirements and older housing stock |
| Denver, CO | $7,300 – $14,800 | 1.06 | 28 days | mid-range labour rates with hail-driven specification requirements and claim-cycle market volatility |
| Philadelphia, PA | $7,400 – $15,200 | 1.14 | 28 days | above-average unionised labour rates combined with attached-housing scope and historic-district constraints |
| Chicago, IL | $7,600 – $15,700 | 1.18 | 28 days | high union labour base plus code-driven cold-climate detailing |
| Seattle, WA | $7,800 – $16,200 | 1.24 | 28 days | high burdened labour rates, long permit and contractor lead times, and an energy code that sets a specification floor |
| New York, NY | $8,400 – $17,700 | 1.38 | 28 days | logistics, insurance and filing procedure on top of the highest permit index modelled |
| San Francisco, CA | $8,600 – $18,200 | 1.42 | 28 days | highest modelled wage base, slow permit throughput and compliance-driven specification floors |
The spread is not arbitrary. Houston sits at the bottom of this table because of deep competitive labour pool and the lowest permit burden modelled, offset by wind-resistance scope, while San Francisco sits at the top because of highest modelled wage base, slow permit throughput and compliance-driven specification floors. Scope, task list and specification are identical in every row — what changes between cities is what it costs to staff, supply, permit and access the same job.

Confidence score: 88/100 (High confidence)
Renolume publishes how much to trust the number instead of hiding the uncertainty. This page scores a standard property; answering the planner questions raises the score because the model has more to work with. Wage data is measured and the cost base is stable, but the market clears at very different prices before and after a storm event, and impact-rated specifications sit above the modelled default.

How this estimate is produced
No contractor supplies these prices, no figure is scraped, and no number is crowd-sourced. Here is the whole chain.
| Step | What happens | Why it matters to you |
|---|---|---|
| 1. Scope | A fixed task library breaks the job into discrete tasks with a trade, a crew size and a productivity rate. This job models 30.5 labour hours across 2 trades. | Nothing is priced that is not described. You can see every task and argue with any of them. |
| 2. Labour | Hours are priced against published government occupational wage data, burdened for payroll costs and scaled to Dallas, Texas by a labour index of 0.96. | The regional difference is an index you can see, not a guess folded into a national average. |
| 3. Materials | Quantities are derived from your inputs with waste factors, then priced at the selected specification and scaled by a material index of 0.99. | Changing specification changes the material line only — the labour model does not silently move. |
| 4. Other costs | Permits, disposal, protection and equipment, with a permit fee index of 0.9. | These are the lines most quotes leave out and most homeowners discover late. |
| 5. Overhead and contingency | 25% contractor overhead and profit, then 7% contingency for conditions nobody can see before the job is opened up. | A real business has to cover both. Estimates that omit them are structurally too low. |
| 6. Confidence | The model scores how much it actually knows about your property and widens the displayed range when it knows less. | You are told how much to trust the number instead of being given false precision. |

Why two honest quotes can differ this much
Modelled spread on this job is $6,800 – $13,700. Real quotes often spread wider, and it is rarely because one contractor is dishonest.
| Reason | What it looks like on the quote |
|---|---|
| Different scope | One bid includes disposal, permits and finishing; the other assumes you handle them. Same headline job, different work. |
| Different specification | Grade of window replacement components — the accessories, not the headline product — is where most silent savings are made. |
| Different risk appetite | A firm carrying a real contingency prices higher and change-orders less. A firm carrying none does the reverse. |
| Different overhead | Licensed and insured crews with warranty support and office staff cost more to run than a truck and two people. |
| Different backlog | A busy contractor prices to be worth interrupting the schedule. The same firm bids differently in the off season. |
| Different assumptions about the unknown | Whoever assumes the least concealed damage looks cheapest on paper and is the most likely to change-order. |
The practical defence is to compare on scope lines rather than totals. Use the breakdown above as the checklist, and ask any bidder missing a line whether it is excluded or simply unpriced.
Repair or replace?
The decision before the budget. Renolume has no reason to push you toward the larger job.
| What you are seeing | What it usually means |
|---|---|
| Glass is fogged between the panes | The seal has failed. On many units the sash alone can be replaced — far cheaper than the whole window and usually overlooked. |
| Draughty but the frame is sound | Repair first. Weatherstripping, new balances and re-caulking recover most of the comfort at a fraction of the cost. |
| Frame is rotten or the sill is soft | Replace, full-frame. An insert over a rotten frame conceals the decay and voids most warranties. |
| Single-glazed throughout a cold-climate home | Replace as a programme, worst elevation first. Doing the whole house at once is materially cheaper per window. |
| Hardware broken, everything else fine | Repair. Balances, locks and cranks are stocked parts for most mainstream brands. |
| You are replacing for energy savings alone | Check the payback before committing. Air sealing and attic insulation almost always return more per dollar than new windows. |
Planning a window replacement
The parts of a window replacement that a cost table cannot tell you.
Installers set most windows in well under an hour each; a whole-home job is often two to three days on site. The calendar is dominated by manufacturing. Windows are made to your measured sizes, so nothing can be ordered until a field measure is complete and nothing can be installed until delivery arrives.
That is why the timeline on this page shows so many waiting days against so few working days, and why the gap widens at the higher specification levels — wood-clad and premium fibreglass are built to order.
This single choice changes removal labour, whether drywall patching and exterior capping are in scope at all, and whether the job needs interior finishing. It typically moves the total more than the frame material does.
Choose insert when the existing frame is square, dry and sound. Choose full-frame when there is any rot, when the original install was bad, or when you want the glass area back.
New windows do cut heat loss, but the payback period on a whole-home replacement is long — commonly measured in decades when energy savings are the only benefit counted. Comfort, noise, condensation, operation and appearance are the reasons most projects are actually worth doing.
If your goal is purely the energy bill, price attic insulation and air sealing first. Renolume would rather tell you that than sell you a bigger project.
Enlarging an opening means a new header and usually an engineered letter. Converting a basement or bedroom window to egress is life-safety work with code-set minimum dimensions and often a window well and excavation.
Both are modelled as separate tasks with their own permit allowance, because both convert a straightforward window job into a structural one.
Terms on your quote, defined
The handful of terms that appear on every quote and change what you are comparing.
- Insert (pocket) replacement
- The new window is fitted inside the existing frame. Faster and cheaper, keeps the exterior trim, but loses 1–3 inches of glass area on every opening.
- Full-frame replacement
- The existing frame is removed back to the rough opening. Required if the frame is rotten, and the only way to correct a bad original install — always brings interior and exterior finishing work with it.
- U-factor
- How much heat the whole unit loses. Lower is better. The rating that matters is the whole-window U-factor, not the centre-of-glass number.
- SHGC (solar heat gain coefficient)
- How much solar heat passes through. Low SHGC suits cooling-dominated climates; higher SHGC helps on south-facing glass in heating-dominated ones.
- Egress window
- A window sized so a person can escape through it. Bedrooms and finished basements are code-controlled here, and converting an opening to egress is structural work, not window work.
- Lead-safe (RRP) work
- Housing built before 1978 requires a certified contractor and contained work practices when disturbing paint. It adds real, unavoidable labour cost.
DIY versus contractor
Savings are labour only — materials, disposal and permits do not change.
You could take on
- Interior protection and furniture moving (easy)
- Haul old units and clean up (easy)
Leave to a licensed contractor
- Field measure and order — Mis-measurement is non-returnable on custom units
- Remove existing windows — Glass handling and weather exposure
- Set, shim, level and fasten windows — Warranty requires certified installation
- Insulate, flash and seal — Licensed or code-regulated work
Owner-performed roof work is a poor fit where impact rating and insurance documentation matter, and summer roof-surface temperatures are a genuine safety limit.
Model your own window replacement in Dallas
Everything above prices a standard property. Your house is not a standard property, and the difference is usually larger than the difference between cities. The window replacement planner runs the same engine on your inputs and returns a cost range, an itemised scope, a phased timeline, Good/Better/Best options and a confidence score that rises as you answer.
- Size, condition and access replace the standard-property defaults behind the $6,800 – $13,700 range on this page.
- 14 named conditions are re-tested against your answers instead of assumed away — each one shown with its cause and its effect.
- The confidence score moves off 88/100, because the model is working from your inputs rather than Dallas averages.
- Local context is carried through: Confirm which municipality you are in, get impact rating quoted explicitly as an option, and check how your insurer treats it.
Open the window replacement planner for Dallas — it takes a few minutes, nothing is emailed to a contractor, and you can save and compare scenarios side by side afterwards.
Key takeaways
- Window replacement in Dallas, TX models at $6,800 – $13,700, mid point $9,500 at the Better specification.
- Expect 14 days to 58 days elapsed, of which only 2.8 days is active work.
- The model states 88/100 confidence for a standard property, and 14 named conditions can move the number.
- Dallas prices differently from other metros because of low labour and permit base offset by hail-driven specification upgrades and post-storm market volatility.
- 25% contractor overhead and profit and 7% contingency are inside the range — a quote without them is not cheaper, it is incomplete.
- Insert versus full-frame moves the total more than frame material does — decide it before you compare quotes.
- Lead time, not installation, sets your calendar. Order as early as the measure allows.
- Fogged glass often needs only a sash, not a whole window.
- Whole-home orders are materially cheaper per opening than replacing two or three at a time.
- Pre-1978 housing triggers lead-safe work practices and genuine extra labour cost.
- If energy savings are the only goal, insulation and air sealing usually pay back faster.
Questions homeowners ask before hiring
How much does a window replacement cost in Dallas?
A window replacement on a standard property in Dallas, Texas models at $6,800 – $13,700 at the Better specification, with a mid point around $9,500. That figure is a whole-job model — labour, materials, 1 other cost lines, 25% contractor overhead and profit and 7% contingency — not a per-unit line item multiplied out.
Which material makes the most sense in Dallas?
In Dallas the same scope models at $6,800 – $13,700 with vinyl and $11,200 – $21,600 with wood-clad (wood interior, aluminium or fibreglass exterior), so material is the largest choice you control on this project. Solar heat gain control is the performance number that pays back here; occasional hard freezes mean the assembly still needs to tolerate cycling, but cooling dominates. This page compares every modelled option side by side; each material has its own page setting out service life, upkeep and the cases where it is the wrong choice.
Why does a window replacement cost more or less in Dallas than the national average?
Three published indices explain almost all of it: a labour index of 0.96 against the national wage base, a material index of 0.99 covering freight and local supply, and a permit fee index of 0.9. Dallas–Fort Worth has one of the largest and most competitive residential trade markets in the country, spread across two urban cores and a very wide suburban ring. Rates are below the national basis and quote quality varies accordingly. Nothing about the job itself changes between cities — only what it costs to staff, supply and permit it.
Do I need a permit for a window replacement in Dallas?
Permitting is comparatively fast and inexpensive, but it is administered by a large number of separate municipalities with their own requirements for roofing and exterior replacement. A permit line is modelled into this estimate at $0 – $400, scaled by the Dallas permit fee index of 0.9. Treat it as a budgeted allowance and confirm the exact requirement with your local building department before work starts — an unpermitted job can create problems at resale.
What will the inspector check in Dallas?
Inspection focuses on fastening schedules, wind resistance and, where relevant, impact-rated assemblies. Documentation matters for insurance treatment as much as for the building department. Renolume models 2 days of inspection wait inside the 28 days elapsed timeline, because the waiting — not the inspection itself — is what shows up on your calendar.
How hard is it to get a good contractor in Dallas?
Very deep pool, with severe compression after hail. The post-storm influx of out-of-area crews is a recurring local problem and licence verification is essential. Whatever the local market, compare bids on scope lines rather than on the total: this page lists 6 modelled tasks and 1 other cost lines, and a bid that is missing several of them is not cheaper, it is incomplete.
When is the best time of year to schedule a window replacement in Dallas?
Year-round working season with two constraints: mid-summer surface heat that shortens productive hours, and a spring storm season that drives both damage and demand. Renolume carries 1 day(s) of weather buffer for this metro inside the modelled elapsed window of 14 days to 58 days. Off-peak scheduling more often shortens lead time than it lowers price.
How long does a window replacement take in Dallas?
Renolume models 2.8 days of active work and 1 day of waiting — permits, inspections, material lead time and weather buffer — for a total elapsed window of 14 days to 58 days. Crews on site is the short part; the calendar is dominated by what happens between phases.
Can I do a window replacement myself, or do I need a contractor?
Renolume models $0 to $0 of labour that a capable owner could take on — typically Interior protection and furniture moving, Haul old units and clean up. These stay with a licensed contractor: Field measure and order, Remove existing windows, Set, shim, level and fasten windows, because of code, insurance or safety exposure. DIY savings are labour only; materials, disposal and permits do not change.
Is insert or full-frame window replacement better for my house?
An insert (pocket) replacement keeps the existing frame and exterior trim, so it is faster and cheaper — it is modelled as the default here. Full-frame removes the frame back to the rough opening and is the honest choice when the sill or jambs are rotten, the frame is out of square, or you are changing the window size. Full-frame adds carpentry, interior patching and painting to the scope, which is why the same house can be quoted two very different numbers by two contractors who are not pricing the same job.
Was the house built before 1978? What changes in Dallas?
Disturbing painted surfaces in a pre-1978 home triggers EPA Renovation, Repair and Painting rules: the contractor must be certified and must use lead-safe containment and cleanup. Renolume models that as its own scope line with its own hours and materials, so you can see what it costs instead of finding it as a change order. Solar heat gain control is the performance number that pays back here; occasional hard freezes mean the assembly still needs to tolerate cycling, but cooling dominates.
Should I replace every window at once or in phases?
Phasing spreads the spend but repeats the fixed costs: mobilisation, measure trips, permit and minimum-order pricing all get paid twice. This model prices 6 scoped tasks as one mobilisation. If cash flow forces phasing, split by elevation or by failure severity — not evenly — and re-run the planner with the reduced count so the fixed-cost share is shown honestly.
What local factors change this number in Dallas?
Hail frequency: Impact-rated assemblies are a mainstream decision here and can affect insurance treatment as well as survival. Heat and UV: Sustained summer attic temperatures and high UV shorten the life of low-grade materials and make ventilation cost-relevant. Storm-cycle demand: Prices and lead times move sharply after a hail event, independently of the underlying cost base. Municipal fragmentation: Dozens of separate authorities across the metroplex, each with their own process and requirements. All three published indices behind those factors are stated on this page — labour 0.96, material 0.99, permit 0.9 — and 1 day(s) of local weather buffer are carried in the timeline. Site access, storey height and existing conditions are modelled separately in the planner because they are property-specific, not city-specific.
Is it worth repairing instead of a full window replacement?
A targeted repair is normally worth it when the failure is isolated and the rest of the assembly still has service life. Once the damaged share approaches roughly a third of the whole, repair economics collapse — you pay set-up, access and disposal twice, and the two halves age differently. Model the full job at $6,800 – $13,700 first, then compare a quoted repair against it rather than against a national average.
How accurate is this estimate for Dallas?
This page carries a confidence score of 88/100 (High confidence) for a generic property, because it assumes a standard case rather than yours. Wage data for Dallas is measured sample quality (CBSA 19100), which is one of the 5 stated factors behind the score. Answering the planner questions raises it, because the model then has real inputs instead of defaults.
Where does the Dallas cost data come from?
Labour hours come from a fixed task library, wage rates from published government wage data at measured sample quality for Dallas, and regional movement from a labour index of 0.96, a material index of 0.99 and a permit index of 0.9. Nothing is scraped, crowd-sourced or supplied by a contractor. Data version v2026.1, effective 2026-04-01.
Assumptions, exclusions and data sources
These are the model's standing assumptions for a Dallas property. Where local practice overrides them — permits, inspections, season — that is set out in the Dallas sections above.
- Unit pricing assumes standard sizes at the average size you supplied; oversize or custom-shape units cost materially more.
- Insert installations retain the existing frame and exterior trim.
- Lead time, not labour, dominates the schedule on this project.
