AfterHow Much Does New Window Installation Cost in San Antonio?
New window installation in San Antonio typically runs between $450 and $1,400 per window, with most full-home projects landing in the $6,000 to $18,000 range depending on window count, frame material, glass package, and labor. A standard vinyl double-hung replacement on a one-story San Antonio home usually costs about $600 to $900 per opening, installed. High-end options like impact-rated windows or wood-clad frames push that number past $2,000 per unit.
Those are real numbers we see every week when we write estimates for homes in Alamo Heights, Stone Oak, King William, and the neighborhoods in between. The single biggest factor is rarely the window itself. It’s the condition of the opening, the age of the house, and how much of the original frame is still sound.
We’re Lightwell Windows San Antonio, part of the Cedarwell network since 2010, and led by Keith Yamada. Every quote we give is a written price before any work starts. If you’d like a straight answer for your specific house, call us at (325) 420-4173 and a live person will pick up. No voicemail maze, no estimate-by-text where the numbers shift a week later.
New Window Installation Cost Breakdown (2026)
Here’s how new window installation pricing breaks down across the San Antonio market in 2026. These ranges reflect what we and other reputable local installers are charging per opening, including labor, basic trim work, and haul-away of the old window.
| Item | Typical Cost Range (Per Window) | Notes |
|---|---|---|
| Basic vinyl window, single-hung or double-hung | $450 – $750 | Standard glass, no special coatings. Most common choice for rental properties and flip jobs. |
| Mid-grade vinyl window, insulated glass with Low-E | $650 – $950 | Good fit for Texas sun exposure. Meets current energy code expectations. |
| Premium vinyl or fiberglass window | $900 – $1,400 | Stronger frames, better U-factor and SHGC numbers. Common in Alamo Heights and Terrell Hills remodels. |
| Aluminum window (standard, non-impact) | $500 – $900 | Less common in residential now, but still ordered for some mid-century homes. |
| Impact-rated window (PGT, CGI) | $1,200 – $2,800+ | Heavy glass, reinforced frames. Pricing rises steeply with size and design pressure ratings. |
| Wood or wood-clad window (Mr-Glass, ES Windows) | $1,300 – $3,000+ | Custom sizes, historical district requirements often apply. |
| Full-frame replacement (includes tearing out old frame) | Add $150 – $400 per opening | Needed when the existing frame is rotted, out of square, or you’re changing window type entirely. |
| Disposal and haul-away of old windows | $25 – $75 per window | Some contractors add this as a separate line. Our written quotes include it. |
For a typical 3-bedroom, 2-bath San Antonio house built between 1985 and 2005 with 12 to 16 windows, a full-home replacement using mid-grade vinyl with Low-E glass lands between $9,000 and $14,000. Go impact-rated, and the same house runs $18,000 to $30,000. That’s a wide spread, but the factors below explain exactly where your home lands inside it.
What Affects New Window Installation Pricing in San Antonio
Every estimate we write starts with a walkthrough, but these are the levers that move the cost in one direction or the other.
- Window count and size. A 36″ x 60″ single window costs less than an 8-foot wide picture window. Odd sizes and oversized openings push the per-unit price because the glass package and frame get custom-ordered. Most San Antonio ranch-style homes have standard sizing, which keeps costs predictable; custom homes in Stone Oak and The Dominion often don’t.
- Frame material. Vinyl is the entry point. Fiberglass and wood-clad step up in price and longevity. Aluminum is rarely cheaper than mid-grade vinyl now, and it conducts heat into the house during San Antonio summers in a way that makes it a poor fit for west-facing walls.
- Glass package and energy ratings. Low-E coatings are standard now, but double-pane argon-filled glass, triple-pane, or specialized low-solar-gain coatings for south and west exposures all add cost. A home in the 78209 zip code with unshaded afternoon sun may justify a higher SHGC glass than a shaded lot in Olmos Park.
- Full-frame vs. retrofit installation. A retrofit (or “pocket” or “insert”) installation fits a new window inside the existing frame. A full-frame replacement removes everything down to the studs. Full-frame costs more in materials and labor, but it’s the right call when the original frame shows water damage or when you’re changing from aluminum sliders to double-hungs and the opening geometry shifts.
- Stucco and masonry work. Many San Antonio homes are brick-veneer or stucco. Removing an old window from a stucco exterior often requires patching the surrounding wall, which can add $150 to $500 per opening depending on the finish texture and paint matching. Brick exteriors are more forgiving; stucco is not.
- Second-story access and obstructions. Two-story homes cost more per window because the crew is working on ladders or scaffolding, which slows the job and raises labor. If a window sits above a sunroom, a pool cage, or a complicated roofline, expect a modest bump.
- Historic district requirements. King William, Monticello Park, and parts of Monte Vista have design review boards that may require wood frames, specific muntin profiles, or custom colors. Compliance adds both material cost and permitting time. We’ve worked with clients in those neighborhoods and can tell you exactly what the local board will accept before you commit.
How to Save on New Window Installation
You don’t need to buy the cheapest windows in the showroom to come out ahead. The smartest savings in San Antonio come from sequencing the work correctly and knowing which upgrades actually pay back.
Replace windows in phases by exposure. If the whole house isn’t in the budget this year, start with the west- and south-facing windows. Those take the most direct San Antonio sun from April through October. Replacing those first lowers cooling bills during the months that cost you the most. North-facing windows can usually wait.
Stick to standard sizes when you can. Custom sizing is not a penalty for luxury; it’s the single fastest way to double a window’s price. If an opening is a few inches off a standard dimension, we can often adjust the rough opening rather than pay a custom-glass premium. That’s the kind of thing a written estimate makes visible, and it’s one reason we put every number down before we start.
Don’t oversize the glass package for shaded rooms. A north-facing window under a porch roof in Terrell Hills does not need the same low-solar-gain glass as a west-facing wall in Alamo Ranch with zero shade. Matching the glass to the actual solar exposure saves money without sacrificing comfort. Our estimate will show the difference in plain English, not spec-sheet shorthand.
Bundle installation with door replacement. We carry Therma-Tru entry doors and can replace a front door while the crew is already on-site with the scaffolding and tools out. Bundling window and door work on one visit saves a second mobilization charge and gets everything under the same written price.
Ask about current manufacturer rebates. Brands we carry, including PGT and ES Windows, periodically run seasonal rebates. We pass those through on the written quote. There’s no trick to it; if a rebate exists, it shows up as a line item.
We also offer free estimates. Call (325) 420-4173, and we’ll give you a real number for your house, in writing, before you decide anything. No deposit required just to see the numbers.
Why San Antonio’s Climate Shapes Window Pricing
San Antonio is hot and humid, with summer afternoon temperatures routinely above 95°F and a late-summer stretch where the overnight low stays above 78°F for weeks. That’s the physical reality your windows live in. The heat load isn’t theoretical; it’s pushing against your glass every afternoon from May through September.
What that means practically: we recommend windows with a lower Solar Heat Gain Coefficient (SHGC) than a contractor in, say, Minneapolis would ever suggest. Most San Antonio homes benefit from SHGC ratings under 0.25 on south- and west-facing windows. That spec reduces solar heat gain through the glass while still letting in daylight. A light well, after all, is what brings daylight deep into a building. That’s what a well-installed window should do for your home: let the light in without letting the Texas sun punish your air conditioner.
We also see condensation issues in San Antonio that drier climates rarely deal with. Humidity in the Hill Country and inside the 410 loop isn’t coastal, but it’s enough that failed seals on older double-pane windows show up as fog between the panes after a decade or so. If you’ve got fogged windows, the glass package has failed and no amount of caulk will reverse it. That’s a replacement, not a repair.
Climate also affects the sealants we use. We’re careful to choose products that remain flexible and stable through the temperature swings San Antonio sees between January frost mornings and August heat. And wherever there is a pet-safe alternative, that’s what goes on the job. It matters in homes with kids and dogs who will investigate every new smell on the windowsill.
Signs It’s Time to Replace (Not Repair) Your Windows
You’re reading a pricing guide, so you probably already suspect replacement is coming. Here’s how to tell for sure, without guesswork.
- Drafts you can feel with the window closed. Run your hand along the edges on a windy day. If air is moving, the seal, the weatherstripping, or the frame has failed. Caulk can fix minor gaps; drafty frames need replacement.
- Fog or condensation between panes. This is a failed insulating glass unit. It can’t be wiped off; it’s inside the sealed space. The only true fix is new glass, and on older windows replacing the whole unit is usually the better dollar-for-dollar move.
- Sash or frame rot. In San Antonio’s humidity, wood frames that weren’t properly flashed or maintained will rot along the bottom corners. If the wood is soft enough to indent with a screwdriver, the structural integrity is gone. Patching wood rot on a rotted window frame is a temporary patch, not a fix.
- Windows that won’t open or stay open. Older double-hung windows with failing balances and springs become a safety issue and a daily frustration. If you can’t open a bedroom window without propping it with a stick, that’s a sign the hardware is done.
- Rising cooling bills in summer. Single-pane aluminum frame windows, common in San Antonio homes built before 1980, transfer heat directly into the house. Upgrading to insulated double-pane Low-E glass almost always drops cooling costs by a noticeable amount for homes with original windows.
What the Installation Day Looks Like at Lightwell San Antonio
Homeowners aged 30 to 50 with kids and pets have been burned before by crews that left dust on the floors, moved things without asking, or handed them an invoice that looked nothing like the estimate. We hear those stories on nearly every estimate visit. So here’s what we commit to, in writing, on every window installation job in San Antonio.
Our technicians are background-checked, uniformed, and follow the C.A.R.E. values on every visit. That’s not a slogan on a uniform patch; it’s the standing operating rule. Clean up like it’s our own home. Ask before we move or touch anything. Respect the family’s time and quiet hours. Explain the price before the work.
In practice, that looks like shoe covers and drop cloths on every visit. A photo of the clean-up is taken before the crew leaves, so you can see the floors and sills are clear even if you weren’t home. We’re careful around nap schedules for young kids, and we keep tool noise contained to the work area. Where there’s a choice between a standard caulk and a pet-safe product, the pet-safe option goes on the job. The 365-Day Done Right Promise is stamped on every job, not just the easy ones. If the finished work is not right, Lightwell makes it right, no debate and no countdown.
Keith Yamada runs our San Antonio location. He’s the one who answers estimate questions, walks the job with you, and stands behind the numbers. A light well is what brings daylight deep into a building. That’s the standard we hold: a window that works like it’s supposed to, a price that was clear from the start, and a crew that treats your house like a home.
New Window Installation Cost in San Antonio Neighborhoods
Here’s what we see across the different parts of the city, based on typical home age, window condition, and what local design standards require.
Alamo Heights, Terrell Hills, Olmos Park. Older, well-kept homes, many from the 1920s through the 1960s. Wood window replacement is common, and the local aesthetic favors wood-clad or fiberglass frames. Expect per-window costs at the higher end of the range, especially if a historic review applies. Residents here often choose ES Windows or Mr-Glass for custom sizing and wood interiors.
Stone Oak, The Dominion, Sonterra. Large custom homes, many built in the 1990s and 2000s. Windows are bigger, second-story work is common, and the expectation is usually premium vinyl or impact-rated glass. Full-home replacement projects here often run $20,000 to $35,000 depending on window count and frame choices.
King William, Monte Vista, Monticello Park. Historic districts with stringent design requirements. Wood frames, true divided lites, and custom colors are often non-negotiable. That pushes costs toward $1,800-plus per window even for standard sizes. We’ve navigated the local review boards and can tell you up front what will pass.
Leon Valley, Balcones Heights, Universal City. A mix of 1960s to 1980s homes, many with original aluminum single-pane windows. These are usually full-frame replacement candidates, and most owners choose mid-grade vinyl with Low-E glass. Per-window cost is moderate, but full-frame work adds labor. Most projects land between $8,000 and $15,000.

Impact Windows in San Antonio: Cost and When They’re Worth It
San Antonio sits inland but close enough to the Gulf to feel the effects of tropical systems, and spring storms regularly bring high wind events. Impact-rated windows, from manufacturers like PGT and CGI, are engineered to withstand debris impact without shattering, and they carry design pressure ratings that meet Texas and coastal style codes.
Impact windows cost roughly double to two-and-a-half times what a standard vinyl window of the same size runs. The glass is thicker and heavier, the frames are reinforced, and installation requires more care and time. A standard 36″ x 60″ impact window in San Antonio runs about $1,400 to $2,200, installed. A full-home project with 15 impact windows lands between $25,000 and $40,000.
Are they worth it here? For most San Antonio homes, standard insulated Low-E windows with a strong frame are adequate for the weather. Impact windows make sense for homes in wind-exposed areas around Loop 1604, properties where the home is unoccupied for long stretches and storm-prep isn’t practical, or when the homeowner wants the added security benefit of laminated impact glass. They also reduce outside noise noticeably, which matters on busy corridors like Blanco Road or Bandera Road.
Home is where we keep a full list of what’s available, but every window decision starts with a conversation and a walkthrough. Call us at (325) 420-4173 and we’ll talk through what’s right for your home, including whether impact windows are a reasonable spend or an overreach.
FAQs – New Window Installation Cost
How much does it cost to install a new window in San Antonio?
A single new window installation in San Antonio costs between $450 and $1,400 for most homes, with a typical mid-grade vinyl double-hung running $650 to $950 installed. That includes labor, the window itself, and haul-away of the old unit. Larger or impact-rated windows run higher. Call (325) 420-4173 for an exact written quote; estimates are free.
Is it cheaper to repair or replace windows?
It depends on the failure. Replacing a fogged glass unit or worn weatherstripping on a sound frame is usually cheaper than a full replacement, typically $150 to $400 per window. But if the frame is rotten, out of square, or over 25 years old, you’re often better off replacing the whole unit at $450 to $1,400. Repairing a 30-year-old window often becomes a recurring expense that adds up to more than one clean replacement.
How much does a full-house window replacement cost in San Antonio?
A full-house replacement for a typical San Antonio home with 12 to 16 windows runs $6,000 to $18,000 using mid-grade vinyl, depending on size, frame condition, and whether the job is retrofit or full-frame. Impact-rated or wood-clad full-home jobs can exceed $30,000. The best way to know your number is a free walkthrough; call (325) 420-4173 and we’ll put it in writing.
Can you match the style of my home’s original windows?
Yes. We carry ES Windows and Mr-Glass for wood and wood-clad options that match historic and mid-century styles, and our team has done work in San Antonio’s historic districts where design review boards require specific profiles. You’ll know the exact frame, glass, and muntin specs before the order is placed. That’s part of the written price: no surprises about what the window will look like when the crew leaves.
Will new windows actually lower my energy bill in San Antonio?
Homes with original single-pane aluminum windows usually see measurable cooling savings after upgrading to double-pane Low-E glass, often in the range of 15 to 30 percent on summer cooling costs depending on home size, shading, and thermostat habits. The savings are biggest on south- and west-facing windows. New windows don’t magically fix an under-insulated attic, but replacing the original glazing is the highest-impact step for most San Antonio homes.
How long does new window installation take?
Most San Antonio jobs with 10 to 16 windows take one to three days of on-site work, with special-order windows adding two to six weeks of lead time before installation begins. We schedule an exact installation window once the windows arrive at our shop, and we’ll tell you in advance if weather is likely to delay anything.
Do you handle the permits for window replacement in San Antonio?
Yes. We handle the city permitting for jobs where a permit applies, which is typical for full-frame replacements and any structural change. The cost shows up as a line item on the written quote. Historic district approvals take longer and we’ll manage that process for you including the design review submission.
Can you come today for an estimate?
We can often schedule a same-day or next-day estimate in the San Antonio area depending on the crew schedule. A live person answers the phone 24/7 at (325) 420-4173. Tell us you’re calling about a window estimate and we’ll get you on the board.
