Low: 8 windows
$3,200–$7,200
Standard-size vinyl inserts; frames stay because they are sound.
Typical: 12 windows
$4,800–$10,800
Whole-house vinyl inserts on a one-story home.
High: 20 windows
$14,000–$30,000
Fiberglass inserts on a larger two-story home.
Our planning estimate for replacement windows in Tulsa is about $400–$900 per window installed for standard-size vinyl inserts and $700–$1,500 for fiberglass, based on the national ranges published by Angi, Fixr, Modernize and Pella and reviewed in October 2026. That puts a 12-window vinyl project at roughly $4,800–$10,800 and a 20-window fiberglass project at $14,000–$30,000. The figures cover the window, removal of the old unit and standard installation; they leave out rot or framing repair, the extra cost of full-frame openings (up to double), interior trim or paint, and any permit. Frame material, window count and whether each old frame can stay move the number most. They are built from national published ranges, not a measured Tulsa average.
What 8, 12 and 20 windows cost in Tulsa
Three whole-house scenarios, each priced two ways. Find the row closest to your window count, then the column for the frame you're considering; add the full-frame line for any openings with damaged or metal frames.
| Scenario | Typical house | All vinyl inserts | All fiberglass inserts |
|---|---|---|---|
| 8 windows | Small home, or the worst-condition windows first | 8 × $400–$900 = $3,200–$7,200 | 8 × $700–$1,500 = $5,600–$12,000 |
| 12 windows | Typical one-story home | 12 × $400–$900 = $4,800–$10,800 | 12 × $700–$1,500 = $8,400–$18,000 |
| 20 windows | Larger two-story home | 20 × $400–$900 = $8,000–$18,000 | 20 × $700–$1,500 = $14,000–$30,000 |
| Add if 2 openings need full-frame | Rotted or metal frames found at the measure | up to +$1,800 | up to +$3,000 |

Get a quoteFrame material is the biggest choice you control
Material sets most of the per-window price because the frame and sash are most of what you buy: vinyl extrusions are the cheapest to make and install, fiberglass and composite frames are stiffer and paintable but cost more to produce, and wood needs interior finishing and exterior cladding. Across the four national guides we read, vinyl lands around $400–$900 a window installed and fiberglass around $700–$1,500. Composite is the row the sources disagree on most, so treat its band as wide on purpose.
| Frame material | Published ranges, per window | Planning band, per window |
|---|---|---|
| Vinyl | Angi $100–$900; Fixr $350–$800; Modernize $400–$850; Pella $800–$1,600 | $400–$900 |
| Fiberglass | Angi $500–$1,500; Fixr $400–$1,500; Modernize $900–$1,400; Pella $1,100–$2,200 | $700–$1,500 |
| Wood | Angi $150–$1,300; Fixr $600–$2,000; Modernize $800–$1,500; Pella $1,100–$2,200 | $700–$1,750 |
| Composite | Angi $300–$1,200; Fixr $300–$2,500; Modernize $1,000–$1,800 | $300–$1,800 |
Window style and size
A double-hung or slider is a standard rectangle with simple balances; casements and awnings add crank hardware and hinges; picture windows can be large sheets of glass; bays and bows are three to five units joined into a projecting assembly that needs its own support and often a small roof. Size moves the price within every row, so a large picture window can cost more than a small casement. The published style ranges are mixed-material, so read them alongside the material table rather than adding the two.
| Window style | Published ranges, per window | Planning band, per window |
|---|---|---|
| Double-hung | Angi $150–$650; Fixr $300–$1,000; Modernize $429–$915; HomeAdvisor $300–$800 | $300–$850 |
| Casement | Angi $150–$1,000; Fixr $400–$1,200; Modernize $597–$1,273; HomeAdvisor $275–$750 | $350–$1,100 |
| Slider | Fixr $700–$1,500; Modernize $775–$1,652; HomeAdvisor $325–$1,200 | $700–$1,500 |
| Picture | Angi $65–$700; Fixr $300–$1,600; Modernize $600–$1,900 | $300–$1,600 |
| Bay | Angi $900–$7,100; Fixr $900–$4,500; Modernize $1,700–$3,700 | $900–$4,500 |
| Bow | Angi $1,500–$6,500; Fixr $1,500–$8,000; Modernize $1,810–$3,859 | $1,500–$6,500 |
Insert or full-frame replacement
An insert keeps the existing frame and sets a new unit inside it, so the job is mostly removing sashes, setting, sealing and trimming. Full-frame removes the old frame down to the rough opening, which adds tear-out, new flashing and insulation, and exterior trim or capping, and it is the only honest option when the frame is rotted or the old windows are steel or aluminum. Most guides don't publish a separate full-frame price. HomeAdvisor says frame replacement can raise the cost by as much as 50% to 100%, so we budget a full-frame opening at anywhere from the insert price up to twice it.
| Method | What comes out | When it's used | Planning band, per opening |
|---|---|---|---|
| Insert (pocket) | Sash, balances and stops; the old frame stays | Frame is square, dry and solid | Vinyl $400–$900; fiberglass $700–$1,500 |
| Full-frame | Everything down to the rough opening, including the old frame and often exterior trim | Rot, water damage, steel or aluminum frames, or you want more glass area | Vinyl $400–$1,800; fiberglass $700–$3,000 |
See insert vs. full-frame window replacement for how to tell which your openings need.
Window count and whole-house totals
Count is the multiplier on everything above. Some installers price a whole-house order lower per window than a two-window job because the visit, setup and haul-away are spread over more openings, but none of the sources publishes a reliable discount rate, so our scenarios assume none. Angi's national count table lands inside our vinyl arithmetic.
| Windows in the project | Angi published total | Our modeled vinyl total |
|---|---|---|
| 6–8 | $4,500–$6,000 | $3,200–$7,200 (8 vinyl) |
| 8–12 | $6,000–$9,000 | $4,800–$10,800 (12 vinyl) |
| 12–16 | $9,000–$12,000 | — |
| 16–20 | $12,000–$15,000 | $8,000–$18,000 (20 vinyl) |
| 20–24 | $15,000–$18,000 | — |
Manufacturer and big-box prices
Manufacturer and big-box figures run higher than the aggregator guides. Pella publishes general national averages for professionally installed replacement windows of $800–$1,600 for vinyl and $1,100–$2,200 for fiberglass; it is one of the four inputs whose medians set our bands, which pulls them up. The Home Depot's full-service estimate rolls the window, permit, installation and tax into one per-unit number across a wide size range, which is why its ranges are so wide; we show it separately rather than blending it in:
| Style | Vinyl, per unit | Wood, per unit |
|---|---|---|
| Double-hung | $478–$2,412 | $1,311–$4,424 |
| Casement | $589–$2,993 | $833–$3,220 |
| Awning | $750–$1,886 | $871–$2,986 |
| Bay | $3,554–$10,245 | $3,461–$12,452 |
Condition, access and the age of the house
The scenario totals assume sound frames you can reach from the ground or a short ladder. What turns a planning range into a higher written quote is usually found at the opening itself: water damage in the sill, metal frames, a second-story opening over a porch roof, or old painted trim that triggers lead-safe work. Those costs are real, but nobody can price them honestly before looking.
| Condition | Why it moves the price | How it shows up on a quote |
|---|---|---|
| Rotted sill, jamb or framing | The opening must be rebuilt before a window can be set; often forces full-frame | Priced after the old window comes out or the frame is probed |
| Steel or aluminum frames | No wood frame to set an insert into, so the opening is usually full-frame | Per opening, at the full-frame band |
| Second story, over a roof or hard access | More labor, ladders or lift time and more protection | Per opening, as an access line |
| Pre-1978 painted trim or sash | Federal lead-safe work practices apply when paint is disturbed | Lead-safe setup and cleanup as a separate line |
| Oversized, arched or custom shapes | Made to order, longer lead time, more installation time | Quoted per unit after measuring |
What's different about pricing windows in Tulsa
Permits
Inside Tulsa city limits, a same-size, same-location window swap doesn't need a building permit, so there's no permit line on most Tulsa replacement quotes. Change the size or location of an opening and it becomes an alteration that does. The suburbs don't all follow Tulsa's exemption, and historic districts add their own approval:
| Where | Same-size replacement | Enlarged, new or moved opening |
|---|---|---|
| City of Tulsa | No permit: the city lists “replacing existing windows of the same size and location” as work that does not need one | Building permit (residential alteration) |
| Broken Arrow | Window replacement is not on the city's permit-exemption list; confirm with Broken Arrow Permitting before work starts | Building permit |
| Owasso | No window-specific rule; the city asks you to call Building Services at 918-376-1534. Its fee schedule lists a $50 residential remodel permit (no structural change) plus a $4 state fee | Building permit |
| HP-zoned historic neighborhoods (Tulsa) | HP Permit from the Tulsa Preservation Commission before exterior work, with a window survey form | HP Permit plus building permit |
Our Tulsa permits and historic-window guide covers the HP Permit paperwork in more detail.
Bedroom windows and egress
Oklahoma adopted the 2024 International Residential Code as its statewide residential code effective September 14, 2026 (OAC 748:20-6-1); the City of Tulsa's own ordinance update is pending for January 1, 2027. Both editions let a replacement bedroom window skip the escape-opening size and sill-height rules if it is the manufacturer's largest standard size that fits the existing frame or rough opening, is the same operating style or one with an equal or larger opening, and isn't part of a change of occupancy (2024 IRC R319.5; 2018 IRC R310.2.5). That matters for cost because swapping a bedroom double-hung for a smaller-opening style can force a larger, more expensive unit or a resized opening.
Energy ratings for Tulsa County
ENERGY STAR places Tulsa County and the neighboring Wagoner, Rogers and Creek counties in its South-Central zone, where a qualifying window needs a U-factor of 0.28 or lower and a solar heat gain coefficient of 0.23 or lower. Low-SHGC glass is the part worth paying for on west- and south-facing Tulsa windows; you don't need a northern triple-pane spec to meet it.
| County | ENERGY STAR zone | Window criteria (U-factor / SHGC) |
|---|---|---|
| Tulsa, Wagoner, Rogers, Creek | South-Central | U ≤ 0.28, SHGC ≤ 0.23 |
| Osage County ZIP codes (Skiatook, Hominy, Pawhuska) | North-Central | U ≤ 0.25, SHGC ≤ 0.40 |
Rebates, tax credits and sales tax
Plan without a utility rebate unless you find a current one. PSO's rebate finder lists windows only under business programs (its window-film rebate is for commercial buildings), and Oklahoma Natural Gas rebates cover ranges, dryers, water heaters and heating systems. The federal Section 25C credit is not allowed for any property placed in service after December 31, 2025, so it doesn't apply to a 2026 installation. On sales tax, Oklahoma treats contractors as the consumer of the materials they buy for real-property work (OAC 710:65-7-13), so the tax on the windows is normally inside the installed price rather than added on top.
Regional prices versus national ones
The only regional price source we found is Remodeling magazine's 2025 Cost vs. Value report. For its defined upscale project (ten 3×5-foot double-hung windows with custom-color exteriors and simulated divided lites), the West South Central region, which includes Oklahoma, came in at $20,171 for vinyl against $22,073 nationally, and $25,062 for wood against $26,781. That is region-wide and for a premium spec, so we show it as context and don't apply it to the bands above. City-level aggregator averages for Tulsa exist, but they don't say how many windows or what scope they describe, so we don't use them.
Add-ons and related work
These are the extras that most often appear on a Tulsa window quote, with the published national figures we found. They are not in the scenario totals.
| Option or extra | Published cost | Source and note |
|---|---|---|
| Tempered or laminated glass (one window) | $100–$800 added per window | Fixr; tempered is required near doors, tubs and some floors |
| Triple-pane window | $1,000–$4,000 per window, complete | Angi and Fixr both publish this range for triple-pane units |
| Replace the glass only (insulated glass unit) | $300–$900 for a double-pane unit, glass plus labor | Modernize glass-replacement guide; for a fogged pane in a sound sash |
| Storm window over an existing window | $90–$400 per window | Angi |
| Permit, where your city requires one | $50–$300 national average | Fixr; see the local section for this market |
| Rotted wood around the opening | “can easily add $3,000” to a project | HomeAdvisor; priced only after the frame is opened |
For a single foggy pane in a sound sash, a glass-only repair can be the better spend; see repair or replace your windows.
DIY, hiring a pro and ways to lower the cost
Replacement windows are a reasonable DIY job only for a confident homeowner doing a few ground-floor inserts in sound frames, and even then a mismeasured custom-size window is usually not returnable. Labor is a modest share of the price (Modernize puts it near 15% and Fixr near 30%), so most of the savings come from scope choices, not from skipping the installer:
- Keep frames that are sound. Insert replacement avoids paying for tear-out, flashing and trim, up to double the price, on openings that don't need it.
- Choose material by elevation. Vinyl on the back and sides with a better frame on the street side can cost less than one premium material everywhere.
- Stick to standard operating styles. Swapping a casement for a double-hung or slider where egress and ventilation allow it keeps you in the lower rows.
- Repair one failed pane instead of the whole window when the sash and frame are fine.
- Compare quotes per opening. Divide each written total by the number of openings, same product and method, before reading any discount headline.
Frequently asked questions
How much does it cost to replace one window in Tulsa?
Plan on about $400–$900 for a standard-size vinyl insert and $700–$1,500 for fiberglass, installed. A full-frame opening can cost up to twice as much, and large picture, bay or bow units sit well above those bands. Fixr's national figure for a one-window job is $450–$1,200.
How much does it cost to replace all the windows in a Tulsa house?
Twelve standard vinyl windows plan out at about $4,800–$10,800 installed and twenty at $8,000–$18,000. In fiberglass, the same twenty windows are about $14,000–$30,000. Repairs, full-frame openings and trim work are extra.
Do I need a permit to replace windows in Tulsa?
Not inside Tulsa city limits if the new windows are the same size and in the same location. Enlarging or moving an opening needs a building permit, homes in HP-zoned historic neighborhoods need an HP Permit first, and Broken Arrow and Owasso should be checked with the city before work starts.
Can I get a rebate or tax credit for new windows in Tulsa?
Not that we found. The federal 25C credit ended for windows placed in service after December 31, 2025, PSO's residential rebate finder lists no window measure, and Oklahoma Natural Gas rebates are for gas appliances and heating. Check for anything newer before you sign.
Why does your online budget estimator show a wider range than this guide?
The estimator multiplies your window count by The Home Depot's per-unit full-service bands, which include permits and taxes and cover everything from small to very large units, so eight vinyl double-hungs come out at $3,824–$19,296. This guide uses the narrower middle of four national cost guides. Neither knows your sizes or frame condition; the written quote after the measure does.
How we price this
Basis: modeled estimate from sourced market ranges. Nothing on this page is a Tulsa average or a partner's price list. We read four national cost guides on October 29, 2026: Angi, Fixr (updated January 21, 2026), Modernize (updated September 22, 2026) and Pella (updated October 6, 2026), plus HomeAdvisor for style rows and its full-frame ceiling. For each material or style, the planning band is the median of the published low ends to the median of the published high ends, rounded to $50. A full-frame opening is budgeted from the insert price up to twice it; HomeAdvisor says frame replacement can raise cost by as much as 50% to 100%. Scenario totals are window count × band, with no volume discount.
Included: the window, removal and haul-away of the old unit, and standard installation and sealing. Excluded: rot or framing repair, interior trim and paint, lead-safe setup on pre-1978 homes, bay and bow assemblies, glass upgrades and any permit. Geography: national evidence; no Tulsa multiplier is applied. The Home Depot and Cost vs. Value figures are shown beside the bands, not blended into them.
Our online budget estimator on the quote page uses a different, wider source, so it won't match these scenarios. It also shows the same range when you choose full-frame, flagging that its source doesn't isolate a full-frame rate, while this guide adds a modeled full-frame allowance:
| Scenario | This guide (vinyl inserts) | Our budget estimator (vinyl double-hung) |
|---|---|---|
| 8 windows | $3,200–$7,200 | $3,824–$19,296 |
| 12 windows | $4,800–$10,800 | $5,736–$28,944 |
| 20 windows | $8,000–$18,000 | $9,560–$48,240 |
The fixed written quote after the measure is the price that counts. Pricing reviewed October 29, 2026.
