AfterHow Much Does New Window Installation Cost in San Antonio?
New window installation in San Antonio typically costs $450 to $1,400 per window including materials and labor, with most full-home projects landing between $4,500 and $15,000. For a standard 2,000-square-foot home with 10 to 12 replacement windows, expect to pay $6,800 to $12,500 in 2026. The spread comes down to window type, frame material, glass package, and whether you’re doing a straightforward swap or cutting new openings.
Mason Remodeling Co San Antonio delivers a written price before any work starts, so the number you’re quoted is the number you pay. No verbal estimates that grow on the final bill. Call (254) 269-5071 for a free estimate on your specific home.
New Window Installation Cost Breakdown (2026)
Here’s what window installation costs in the San Antonio market this year, broken down by window style and scope of work. These are real ranges we see across Alamo Heights, Stone Oak, Helotes, Boerne, Leon Valley, and the older neighborhoods inside Loop 410.
| Window Type / Scope | Typical San Antonio Price Range (Per Window) |
|---|---|
| Vinyl double-hung replacement window (standard size, single unit) | $450 – $850 |
| Vinyl casement or sliding window | $500 – $950 |
| Aluminum frame window (common in mid-century SA homes) | $400 – $800 |
| Wood frame window (interior wood, exterior clad) | $800 – $1,400 |
| Fiberglass window | $700 – $1,300 |
| Impact-rated window (hurricane and storm resistance) | $1,200 – $2,500 |
| Full new-construction window (new opening, framing required) | $800 – $1,800 |
| Picture window (fixed, large) | $550 – $1,200 |
| Bay or bow window | $2,500 – $6,500 per unit |
| Garden window | $1,500 – $3,500 per unit |
| Full-home window replacement (10 – 14 windows) | $4,500 – $15,000 total |
These figures assume standard-size openings without rot repair, stucco patching, or reframing. In San Antonio’s older bungalows around Monte Vista, Alta Vista, and King William, a good 30% of window replacements uncover some degree of sill or jamb rot once the old unit comes out. That repair work runs $150 to $500 per opening depending on how deep the damage goes.
What drives the cost up or down? Frame material is the biggest lever. Vinyl is the most affordable and handles San Antonio’s dry heat well. Wood is pricier but adds resale value in historic districts where exterior appearance matters. Fiberglass sits in the middle with better dimensional stability through our temperature swings. Glass packages matter too: a standard dual-pane with low-E runs about $40 to $80 more per window than builder-grade glass. Impact-rated glass, required in some parts of the Gulf Coast but optional in San Antonio, can double or triple the per-window price.
Isaac Pruett, who leads Mason Remodeling Co San Antonio, says the most common pricing surprise in this market is the “hidden second cost”: the original window wasn’t flashed properly when the house was built, and water has been getting behind the stucco or brick veneer for years. That’s the kind of thing a written, itemized quote should account for before demolition starts.

- Mason Remodeling gives a written price before any work starts. No surprises at the end.
What Affects New Window Installation Pricing in San Antonio
- Frame material. Vinyl dominates the San Antonio market because it’s affordable, low-maintenance, and holds up fine in our climate. Wood windows cost 40% to 70% more and require periodic sealing. Aluminum frames, still common in 1950s and 60s-era homes around North Star and Castle Hills, are the cheapest but conduct heat, which pushes up your AC bill from May through October.
- Glass package and energy ratings. A standard dual-pane low-E window meets code in San Antonio, but going to triple-pane, argon-filled glass with a low SHGC (solar heat gain coefficient) adds $60 to $120 per window. Given our 100-degree afternoons, low SHGC glass is the single best upgrade for actual energy savings, especially on south and west-facing walls.
- Number of windows being replaced at once. A single window replacement in San Antonio runs $600 to $1,000 with trip fees and setup time baked in. Replacing 10 or more windows at once brings the per-unit cost down by 10% to 20% because the crew is already mobilized, scaffolding is up, and disposal is consolidated.
- Age and condition of the existing openings. Homes built before 1978 in areas like Jefferson, Woodlawn Lake, and Beacon Hill often have non-standard opening sizes, meaning every window is a special order rather than a stock size. Add $80 to $200 per window for custom sizing, plus whatever water damage repair the old window reveals.
- Access and installation complexity. Second-story windows in two-story homes across Stone Oak and the Dominion require ladder work or scaffolding. Windows with stucco exteriors, common on the north and northwest sides, need careful cutting and patching that adds $100 to $250 per opening versus a lap-siding or brick-veneer install.
- Permits and code compliance. San Antonio requires a building permit for window replacement when the opening size changes or structural work is involved. Simple like-for-like swaps usually don’t need one, but any project involving new openings, egress window addition, or load-bearing header changes does. Permit fees run $75 to $300 depending on scope.
New Construction Windows vs. Replacement Windows
This distinction causes more confusion than almost anything else in window pricing. A replacement window (also called a retrofit or insert window) fits into the existing window frame. The old sashes come out, the new unit slides in, and trim work hides the seam. It’s faster and cheaper: $450 to $1,000 per window in San Antonio.
A new-construction window has a nailing flange on all four sides. The entire old window, including its frame, comes out down to the rough opening. New flashing is installed, the new window is nailed to the studs, and the exterior is re-sealed. You need this when the existing frame is rotted, when window sizes are changing, or when the original flashing was done wrong. New-construction installation runs $800 to $1,800 per window.
In older San Antonio neighborhoods, we regularly find original windows that were “flashed” with nothing more than caulk and hope. Water has been wicking into the sill for decades. A replacement insert would cover the problem; a new-construction install actually fixes it. If you’re in a 1950s brick-veneer house around Terrell Heights or Mahncke Park and your windows fog between the panes, check the sills for soft wood. That determines which installation method you actually need, and it’s a $300 to $500 per window difference you should know about before signing any contract.
Energy Efficiency and San Antonio Weather
San Antonio gets more than 250 sunny days a year, and your windows are the single largest source of unwanted heat gain in the house. A window’s SHGC rating tells you how much solar heat it lets through. For our climate, the Department of Energy recommends a SHGC of 0.25 or lower on east, west, and south-facing glass. Pair that with a U-factor of 0.30 or lower (which measures heat transfer) and you’ll notice a difference in rooms that currently cook in the afternoon.
Low-E coating adds roughly $40 to $80 per window and pays for itself within 4 to 7 years in reduced cooling costs, faster if you’re running your AC from April through October like most San Antonio homes. Argon gas fill between panes adds another $30 to $60 per window and matters more in colder climates than ours. If you’re replacing windows on a budget, spend on low-E and skip the triple-pane upgrade.
One local factor worth knowing: single-pane aluminum windows, still common in 50s and 60s ranch houses across the city, perform terribly in our heat. Replacing 10 of them with dual-pane low-E vinyl windows typically cuts the cooling load in those rooms by 15% to 25%. That’s a real, measurable difference on your CPS Energy bill, not a sales line.
How to Save on New Window Installation
- Replace all windows at once, not one at a time. Mobilization, trip charges, and setup are fixed costs. A 12-window project spreads those costs across 12 units instead of one. Most San Antonio homeowners save 10% to 20% per window doing it this way.
- Choose standard sizes. If your openings fit stock window dimensions, you avoid custom-fabrication charges. This is easier in newer homes in Cibolo, Schertz, and the far west side; harder in historic districts where openings are non-standard.
- Prioritize the worst-facing windows first. If replacing everything isn’t in the budget, do the south and west-facing glass first. Those take the brunt of San Antonio afternoon sun and deliver the fastest energy-return.
- Skip upgrades you don’t need. Triple-pane glass matters more in Minnesota than Texas. Impact-rated windows matter if you’re in a coastal evacuation zone, which San Antonio is not. Spend on low-E and a solid install instead.
- Get a written, itemized quote before committing. At Mason Remodeling Co San Antonio, every project gets a written price before any work starts. You’ll see the line items: window units, labor, flashing, trim, disposal, permit if needed. That transparency is how you avoid the surprise invoice that shows up when the crew is already gone.

When New Window Installation Is Worth the Investment
New windows aren’t a one-year payback project. In San Antonio’s climate, expect a full window replacement to recover its cost in 8 to 15 years through energy savings alone. But there are other reasons to replace that don’t show up on a utility bill:
- Selling the house. Realtors across Bexar County consistently tell us that fogged, stuck, or visibly aged windows are one of the first things buyers flag in a walkthrough. New windows are among the top 5 renovation projects for ROI according to national data, recovering roughly 70% of their cost at resale.
- Comfort. That one room that’s 8 degrees hotter than the rest of the house? That’s not an air-balancing problem. That’s a window problem. Rooms with old single-pane or failed-seal windows are dramatically less comfortable from June through September.
- Noise. If you’re near Loop 410, I-10, or the airport approach path and you’re replacing windows anyway, laminated glass adds $150 to $300 per window and cuts exterior noise noticeably.
- Function and safety. Windows that don’t open, windows painted shut in old San Antonio homes, or windows without functioning locks are a daily frustration and a security issue. New units with proper hardware fix both.

FAQs – New Window Installation Cost
How much does it cost to install new windows in San Antonio in 2026?
Expect to pay $450 to $1,400 per window installed in San Antonio in 2026, with most full-home projects (10 to 14 windows) totaling $4,500 to $15,000. Your exact price depends on window style, frame material, glass package, and whether existing openings need repair. Call (254) 269-5071 for a free written estimate.
Is it cheaper to repair or replace a window?
Repair is almost always cheaper in the short term. Replacing a window sash, fixing a broken balance spring, or replacing failed seals runs $150 to $500 per window from a qualified contractor. Replacement makes sense when the repair cost exceeds half the replacement cost, when the frame itself is rotted, or when you have multiple windows with the same age-related failure. If you’re not sure which path is right, Mason Remodeling will tell you straight: call (254) 269-5071 and we’ll assess what’s repairable versus what should be replaced.
How much does it cost to replace 10 windows in San Antonio?
Replacing 10 standard-size vinyl windows in San Antonio typically runs $4,500 to $8,500 including installation. If you choose wood-clad, fiberglass, or impact-rated windows, that same 10-window project lands between $8,000 and $15,000+. Volume pricing applies when a crew can install all 10 in a single mobilization.
Do I need a permit for window replacement in San Antonio?
Like-for-like window replacement that does not change the rough opening size usually does not require a permit in San Antonio. Any project that enlarges an opening, adds a new window, changes structural framing, or converts a window to a door does require a building permit, which typically costs $75 to $300. Mason Remodeling handles permitting as part of the written quote when it’s needed.
How long does new window installation take?
A standard single-window replacement takes 2 to 4 hours. A full-home replacement of 10 to 14 windows takes 2 to 3 days for a crew of two to three installers, including interior and exterior trim work and cleanup. New-construction installations with stucco or brick patching can extend the schedule by a day or two.
Can you install windows the same week I call?
In most cases, yes. Once you approve a written quote and the windows are ordered (stock sizes arrive in 3 to 10 days), our crew can schedule your install. Custom-size windows take longer, typically 2 to 4 weeks for fabrication. Call (254) 269-5071 to check current scheduling.
Why San Antonio Homeowners Choose Mason Remodeling for Window Work
Window installation is one of those trades that looks simple from the outside but punishes shortcuts. A window that’s not flashed correctly will leak for years before you notice the damage inside the wall. A window that’s not shimmed and level will bind during operation. A window that’s not air-sealed around the rough opening will cost you on every CPS Energy bill.
