How Much Does New Window Installation Cost in San Antonio?
New window installation in San Antonio typically costs between $550 and $1,850 per window in 2026, with most full-home projects on a 1,800-square-foot house landing between $8,000 and $22,000. The single biggest price driver is window material: vinyl runs $550 to $1,100 per window installed, while premium impact-rated aluminum or wood-clad units from brands like PGT or ViewLux run $1,200 to $1,850 or more. Labor in San Antonio adds roughly $100 to $350 per opening depending on accessibility, stucco or brick trim work, and whether the old frame needs reframing.
Those numbers reflect what we see on actual jobs across Alamo Heights, Stone Oak, Helotes, and the older neighborhoods inside Loop 410 every week. If you’re planning a full-home replacement, expect the project to take one to three days depending on the number of windows.

Key Takeaways: San Antonio Window Installation Costs in 2026
- Per-window installed cost: $550 to $1,850 depending on material, glass package, and labor difficulty.
- Full-home replacement (10-15 windows): $8,000 to $22,000 for an average San Antonio home.
- Vinyl is the budget-friendly starting point at $550 to $1,100 per window; premium impact-rated or wood-clad units start around $1,200.
- San Antonio’s heat and hail mean you’ll want Low-E glass and, in many neighborhoods, impact-rated frames – both add cost but pay off in energy bills and durability.
- Labor is billed per window, and older neighborhoods like Monte Vista or Tobin Hill often carry higher labor costs because of aging framing and trim work.
New Window Installation Cost Breakdown (2026)
Here’s what new window installation costs look like in San Antonio by material and window style. These are installed prices – the window, labor, trim, caulking, and basic cleanup included. Exact pricing varies by neighborhood and the condition of your existing framing, but this gives you a realistic range before you start calling contractors.
| Window Type / Material | Average Installed Cost Per Window (San Antonio) | Notes |
|---|---|---|
| Vinyl double-hung (builder-grade) | $550 – $750 | Most common; good insulator, limited color options |
| Vinyl double-hung (premium Low-E, argon) | $750 – $1,100 | Better U-factor; makes a real difference in August |
| Fiberglass double-hung | $900 – $1,400 | Expands less in heat; stronger frames |
| Aluminum single-hung | $450 – $800 | Budget option; less efficient in summer |
| Impact-rated aluminum (PGT, CGI) | $1,200 – $1,850 | Hurricane/hail-resistant; common in Stone Oak and far north SA |
| Wood-clad casement | $1,300 – $2,000 | Popular in Monte Vista, Alamo Heights, Terrell Hills |
| Glass block (bathroom, garage) | $350 – $600 | Fixed windows; privacy and light |
Full-home projects scale from there. A 10-window replacement in a starter home near Woodlawn Lake or Jefferson might total $6,000 to $11,000 in vinyl. The same number of windows in an impact-rated package in Dominion or Cibolo Canyons could run $14,000 to $22,000. Bay and bow windows, picture windows, and oversized sliders are priced as separate line items and tend to run 40 to 70 percent above a standard double-hung because of custom sizing and added structural support.
When you call (903) 488-7019, we’ll ask about the window count, the age of the house, what neighborhood you’re in, and what’s driving the project – energy costs, storm damage, noise, or simply age. That helps us give you a written, line-item quote. No vague “it depends” pricing. The number goes in writing before any work starts.
What Affects New Window Installation Pricing in San Antonio
San Antonio isn’t one market. A window job in an 1890s King William bungalow is a different animal than a 2004 production home in Alamo Ranch. Here’s what actually moves the price on your quote:
- Window material: Vinyl is the least expensive and the most common. Fiberglass costs 30 to 60 percent more because the frame material holds its shape better through San Antonio’s 100-degree summers and the occasional deep freeze. Aluminum is the budget pick for single-hung but transfers heat – not ideal for west-facing windows. Wood-clad is the most expensive and the most common request in historic districts where the exterior sightlines have to match the original.
- Glass package and coatings: Low-E coating, which reflects infrared heat, is not optional in San Antonio. It adds $40 to $100 per window but cuts solar heat gain enough that the cost disappears in two or three summers. Argon gas fill adds $30 to $60 per window. If you’re in a hail-prone corridor north of 1604 – looking at you, Shavano Park and Timberwood Park – impact-rated glass (built to resist wind-borne debris without shattering) is a code-compliant necessity, not an upgrade.
- House age and framing condition: Pre-1980 homes around Jefferson, Edison, and Tobin Hill often have wood framing that’s rotted or out of square. Full-frame replacement with new construction windows runs $150 to $350 more per window than a retrofit insert. On some houses, every opening is a different size – 1970s and 1980s San Antonio subdivisions are notorious for bay windows that are all a half-inch off from one another.
- Number of windows and construction type: Stucco and brick exteriors – dominant in Alamo Heights, Castle Hills, and newer master-planned communities – add labor time because trim must be matched and sealed correctly. Stucco cutting and patching adds $75 to $150 per window when a full-frame replacement is required.
- Second-story and access: Single-story homes on narrow lots in central San Antonio are the easiest jobs. Two-story homes without clearance for scaffolding add $50 to $120 per upper window. If the only access is over a patio cover or a steep grade, expect another bump for safety rigging.
- Permit costs and code compliance: San Antonio requires a building permit for window replacements that alter the opening size. Basic like-for-like replacements often qualify as maintenance and skip permitting, but widening a window or adding a bay unit triggers a permit that costs $75 to $200 depending on scope. In the Alamo Heights and Terrell Hills jurisdictions, the permitting tables and historic review layers add time and paperwork – not much harder on price, but real on the calendar.
How the season affects San Antonio pricing: Window demand here peaks in spring and fall when temperatures are mild. If you’re planning on summer installation, book early – the heat slows crews down and some products, particularly impact-rated glass, run longer lead times in storm season. Planning a fall job around the September-October window is the sweet spot: mild enough to work fast, and the install is done before the winter cold snap.
How Much Does Impact-Rated Window Installation Cost in San Antonio?
Impact-rated window installation in San Antonio runs $1,200 to $1,850 per window installed, or about 40 to 65 percent more than standard Vinyl with Low-E. The price covers the laminated glass that resists wind-borne debris, the heavier frame, and the additional labor involved in setting a heavier unit. In neighborhoods like Stone Oak, Hollywood Park, and The Vineyard, where hail and high-wind storms are persistent, impact-rated units from PGT or CGI have become the default for full-home replacements.
Impact-rated windows earn their cost in the San Antonio market in three ways. First, insurance providers often discount homeowners coverage when a home is fully impact-glazed. Second, they eliminate the need for storm shutters. Third, and this is what people actually notice day to day: the laminated glass cuts outside noise dramatically, which is why we install so many impact-rated units on houses backing up to 1604, 281, and Loop 410.
Vinyl vs. Fiberglass vs. Aluminum: What Should You Pick for San Antonio Weather?
The short version: vinyl works for most homes, fiberglass is the premium solve for extreme heat and wild temperature swings, and aluminum only makes sense if you’re matching an existing aluminum frame on a budget. Here’s the longer answer, from what we see on San Antonio job sites:
Vinyl is the default choice for a reason. It’s inexpensive, easy to install, and the best insulator at the entry-level price point. The knock on vinyl has always been expansion and contraction -San Antonio’s 40-degree temperature swings from morning to afternoon will make cheap vinyl frames creak and settle over time. Premium vinyl with reinforced frames, like what ViewLux puts out, handles this well. At $550 to $1,100 installed, it’s the value pick.
Fiberglass costs $900 to $1,400 per window and is genuinely better at holding its shape through the summer-winter cycles that characterize the Texas Hill Country. The material expands at nearly the same rate as the glass itself, so the seals stay tight for longer. If you’re taking a long view on a home you plan to stay in for 15 plus years, fiberglass starts to look like the better per-year cost.
Aluminum at $450 to $800 per window is the lightest and cheapest but conducts heat. On a south-facing wall, an aluminum frame in August will radiate heat into the room even when the window is closed. The one place we do recommend aluminum is when matching an existing architectural aluminum style – common in mid-century San Antonio homes – where the aesthetics matter and the homeowner accepts the thermal tradeoff.
How to Save on New Window Installation
You can reduce the cost of new window installation in San Antonio without cutting corners on quality. Here are the levers that actually save money:
- Replace all windows at once. Per-window pricing drops when the crew is already on site, the scaffolding is up, and the material order is consolidated. A 12-window job in one go will always cost less per window than three separate 4-window jobs.
- Stick with standard sizes. Custom-sizing adds 15 to 30 percent per window. If your openings can accept a standard size without reframing, you should absolutely choose the standard unit. San Antonio homes built after 1995 in master-planned communities like Alamo Ranch and Stillwater Ranch more often have standard-size openings.
- Retrofit what you can, replace what you must. If the existing frame is solid, an insert window (a new sash and glass in the old frame) saves $100 to $250 per window versus a full-frame replacement. When the frame is rotted, you’ll know quickly – the technician will show you photos.
- Do it in the shoulder season. Late September through early November and February through March tend to be easier to schedule, and you’re not fighting the summer heat for comfort during installation.
- Prioritize by exposure. Short on budget? Replace the west- and south-facing windows first. Those are the ones that cook in the Texas sun. East-facing windows get morning sun but the house cools faster. North windows are the last to do – they rarely carry much heat load.
- Get a written, line-item quote before you commit. Juniper’s pricing is written before work starts. Compare quotes on the line items, not the total. One contractor’s “cheap” quote might be missing trim work, haul-away, or permit fees that show up on someone else’s line item and get hidden on the final invoice.
If you’re not sure whether to repair or replace, call (903) 488-7019. We’ll tell you honestly whether a repair is worth it or whether a replacement is the better long-term call. The estimate is free and the number is in writing.
Is It Cheaper to Repair or Replace Windows in San Antonio?
Repair is cheaper up front: replacing a broken sash, a failed seal, or a cracked pane typically runs $80 to $250 per window. But here’s the math we walk homeowners through all the time: if the window is beyond 20 years old, or the seals have failed on more than a third of the glass, or the frame is starting to show decay, you’re pouring repair money into a unit that’s already at the end of its service life. A new vinyl double-hung installed at $600 to $900 per window is often cheaper over the next ten years than paying $200 per repair call every other year on the original units.
Repair makes sense for an isolated issue: one window with a failed seal, a cracked pane from a lawn mower rock, a hardware problem. Full replacement makes sense when the windows are original to the house, the heating and cooling bills keep climbing, and you can feel the heat radiating through the glass from three feet away. We’ll show you the condition of every window with photos before you make the call.
How Much Does Window Glass Replacement Cost vs. Full Window Replacement in San Antonio?
Replacing only the glass (the insulated glass unit or IGU) costs $150 to $450 per window in San Antonio depending on size and coating. Replacing the entire window unit costs $550 to $1,850. If the frame is square, dry, and in good condition, glass-only replacement is the budget-friendly move. But when the frame seal has failed, the hardware is worn out, or the unit doesn’t open and close properly, glass replacement only treats one symptom and leaves the other problems behind. We’ll tell you with photos which situation you’re in.
How Much Does Labor Cost for Window Installation in San Antonio?
Labor for window installation in San Antonio runs $100 to $350 per window depending on the installation type and the condition of the opening. A simple vinyl insert in a well-maintained 15-year-old house takes 30 to 45 minutes per window. A full-frame replacement in an older home where the frame has water damage can take two to three hours per window and cost at the upper end of that range. The labor also covers trim work, caulking, insulation around the frame, and cleanup. Juniper’s labor is included in the written quote – you’ll see it as a line item, not a vague “installation included” number.
What Does a Typical Full-Home Window Installation Job Look Like in San Antonio?
A full-home replacement of 12 to 15 windows on a typical San Antonio home takes one to three days. Day one is the bulk of the installation: removing old units, setting new ones, insulating and sealing. Day two covers trim work, final caulking, and the walkthrough. Larger custom jobs – big windows, multiple stories, stucco or brick complications – extend to three or four days.
With Juniper, you get the Relay Standard on every job: you book in a tap, a live arrival time shows up on your phone so you’re not sitting around waiting, and you get before-and-after photos of every window as it’s done. The technician is background-checked and uniformed – you’ll know exactly who is walking through your door. When the job’s complete, you get a digital invoice you can pay with a link. No paper chase. And if something isn’t right, the 365-Day Done Right Promise covers it: parts and labor, in writing, for a full year after installation.
What Is the 365-Day Done Right Promise?
The 365-Day Done Right Promise is straightforward: if the work isn’t right, we make it right, for a full year after installation. That covers parts and labor – in writing on every project. Not a pro-rated warranty. Not a “call the manufacturer.” If a window leaks, a seal fails, or a piece of trim comes loose, call us. We come back and fix it. Sean Mackey, who runs Juniper Windows San Antonio, put this promise in place because the window industry’s reputation for dodging callbacks is, frankly, earned. We’d rather be the exception.
We also stand behind our service calls differently: if one of our repairs fails, the second visit is free. No charge, no argument. That’s been our standard since we opened in 2001 as part of the Relay Home Co. family.
8 Product Lines: Which Window Brand Should San Antonio Homeowners Choose?
Juniper Windows San Antonio carries eight product lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. Here’s how we think about them for San Antonio homes:
PGT and CGI are the heavy hitters for impact-rated windows and doors. These are the brands built for hurricane-grade hurricanes, which means they’re over-engineered for San Antonio’s hailstorms and high winds. If you live in a hail-prone corridor or want maximum insurance benefit, these are the picks.
CWS, ES Windows, and ECO Window Systems give us the architectural range – large fixed units, slim sightlines, modern profiles. We use these on custom homes and high-end remodels where the window is a design feature, not just a utility.
Mr-Glass is our go-to for glass repair and replacement at the budget end, particularly when the frame is still solid and only the IGU needs to go.
Therma-Tru is the entry-door specialist in our line card, and they pair naturally with window replacements when the homeowner wants the front door to match the new window profiles.
ViewLux is a premium vinyl line that gives us strong thermal performance at the value price point – a good match for San Antonio’s heat without jumping to fiberglass.
What this means for you: we aren’t tied to one brand. The right window for your project is the one that matches your budget, your home’s architecture, and the specific weather exposure of each wall. That’s why we stock eight lines instead of two.
Do Window Materials Affect the Final Installed Price That Much?
Yes. The spread between a builder-grade vinyl double-hung at $550 and a wood-clad casement at $2,000 is nearly four times, and most of that is the material and glass package. The labor to install either one is similar. What drives the cost up: premium frame material, low-E and impact-rated glazing, custom sizing, and wood species. What drives it down: standard sizing, single-hung instead of double-hung, and choosing a mid-grade material that still handles San Antonio’s climate well.
That’s why it’s worth thinking about each window’s job in the house before we write the quote. A window that faces the brutal south sun earns the premium glass more than a shaded north-side window does. We’ll walk you through the math window by window, because the right answer is rarely “all the same.”
What Are the Most Common Hidden Costs in San Antonio Window Installation?
These are the line items that surprise people, and they’re all avoidable when you have a written, line-item quote:
- Stucco patching: When a full-frame window comes out of a stucco wall, the stucco must be patched and textured to match. $75 to $150 per window. On older homes where the stucco color has faded, matching is harder and costs more.
- Lead paint abatement: Pre-1978 San Antonio homes, like the craftsman bungalows in Beacon Hill and Alta Vista, may have lead paint on window trim. Federal law requires containment and specific disposal. $50 to $200 per window if testing comes back positive.
- Rotted framing repair: Water damage hides inside the rough opening. Once the old window is out, you’ll see what’s behind it. Repairing the header, sill, or jamb adds $75 to $300 per window. This is where the “low” quote often turns into a change order. With a written line-item quote, we show you the rot with photos and tell you the repair number before any additional work starts.
- HOA architectural review: Many San Antonio HOAs – particularly in master-planned communities along 211 and Far West SA – require approval before replacing windows with a different style or color. No cost, but plan two to four weeks for the review.
- Disposal fees: Hauling away old windows and construction waste runs $50 to $150 per job, and sometimes more for large jobs. We include it on the quote; some contractors leave it off.
The takeaway: get the quote in writing with every line item spelled out. A number on a napkin is not a price.

FAQs – New Window Installation Cost
How much does new window installation cost in San Antonio in 2026?
Expect $550 to $1,850 per window installed, or $8,000 to $22,000 for a full-home replacement of 10 to 15 windows. Vinyl is the low end at $550 to $1,100 per window; impact-rated or wood-clad units are the high end at $1,200 to $2,000. Call (903) 488-7019 for an exact written quote – estimates are free.
How much does it cost to install 10 windows in San Antonio?
Ten windows cost $5,500 to $18,500 depending on material and glass package. A 10-window vinyl job in a standard San Antonio home typically lands between $6,000 and $11,000. The same project in impact-rated or wood-clad units runs $12,000 to $18,500. The per-window price drops when all ten are done at once versus one or two at a time.
What is the labor cost to install a window in San Antonio?
Labor runs $100 to $350 per window. A simple insert in a modern opening is on the low end; a full-frame replacement with stucco or brick trim work is on the high end. Labor includes removal of the old unit, framing prep, insulation, setting, trim, caulking, and cleanup, and it should be a clear line item on your quote.
Is it cheaper to replace windows all at once or a few at a time?
All at once, always. Bulk purchasing drops the per-window material price, and your labor is consolidated into one crew visit instead of repeated setups. A 12-window job done in one shot will run 15 to 25 percent less per window than the same 12 done in three separate projects. Call (903) 488-7019 and we’ll quote both scenarios so you can see the difference on paper.
Does San Antonio require a permit for window replacement?
Like-for-like window replacements with no change to the opening usually qualify as maintenance and skip the permitting process. Widening an opening, adding windows, or changing the rough opening triggers a building permit that costs $75 to $200 in San Antonio proper, with additional fees in Alamo Heights and Terrell Hills jurisdictions. We handle permitting as part of the installation when it’s required and will spell it out on your written quote.
How long does new window installation take in San Antonio?
Most full-home window installations of 10 to 15 windows take one to three days. Complex jobs with custom sizing, multiple stories, or stucco repair can run three to four days. With Juniper, you’ll get a live arrival time, photo updates as the work progresses, and a digital invoice at the end. No endless radio silence while the crew is on site.
