New Window Installation Cost - Written Price Before Anything Is Ordered

How Much Does New Window Installation Cost in San Antonio?

New window installation in San Antonio typically costs $450 to $1,400 per window installed in 2026, with most homeowners paying between $6,500 and $14,000 for a full-house project of 10 to 15 windows. Vinyl windows sit at the lower end of that range, while premium fiberglass and impact-rated options from brands like PGT and CGI push toward the top. The final number depends on window count, frame material, glass package, and whether your home sits in a designated windborne debris zone that requires hurricane-rated products.

New Window Installation Cost Breakdown (2026)

Here’s the line-by-line picture for San Antonio in 2026. These numbers are based on what we see in the field across neighborhoods like Alamo Heights, Stone Oak, Terrell Hills, Castle Hills, and the newer developments around Cibolo and Converse. They’re not national averages repackaged. This is the San Antonio market.

What a typical project actually costs

If you’re replacing 12 windows in a standard 1990s-era home in the Stone Oak or Encino Park area with mid-grade vinyl, you’re looking at roughly $7,800 to $10,800. That’s the most common project we quote.

If you’re in a 1950s cottage in Terrell Hills or Alamo Heights with custom sizes, wood window replacement, or rotted frames, expect $13,000 to $19,000 for the same window count. Full-frame work and custom sizing change the math quickly. And if you’re on the far west side near Helotes or in a Hill Country-adjacent pocket where windborne debris codes apply, impact-rated windows from PGT or CGI can push a 12-window project to $14,000 to $22,000.

We install and service eight professional lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That matters because the right product for a 1960s ranch in Jefferson isn’t the right product for a 2010 stucco home in Cibolo. We’ll tell you honestly which line fits your house and your budget, and the price is in writing before anyone picks up a tool.

What Affects New Window Installation Pricing in San Antonio

These are the six things that most move the number on your quote. If you know these coming in, you’ll know exactly what questions to ask.

• Frame material. Vinyl is cheapest, fiberglass is mid-range, and custom wood or wood-clad runs highest. In San Antonio’s heat and humidity, vinyl holds up well and is the most common residential pick. Fiberglass resists warping better for very large spans, like a big picture window facing a Hill Country view.
• Glass package. Single-pane is near-obsolete here. Dual-pane with low-E glass (a thin coating that blocks heat while letting light through) is the San Antonio standard. Add argon gas fill and you’re in great shape for CPS Energy bill savings. Triple-pane exists, but in our climate it’s rarely worth the added cost.
• Impact ratings and windborne debris codes. If your home falls in a windborne debris zone (especially parts of far west San Antonio, Helotes, and areas approaching Bandera County), your windows must meet those wind-load and missile-impact standards. This narrows your product choices to PGT, CGI, and similar rated lines. That’s a several-thousand-dollar difference on a full house.
• Installation type: pocket vs. full-frame. Pocket replacement (setting the new window into the old frame) costs less and is fine when the existing frame is solid. Full-frame replacement pulls everything down to the studs. San Antonio’s older homes in neighborhoods like Monte Vista, King William, and Jefferson often have rotted sills and water-damaged frames under the surface. Spring thunderstorms, cedar pollen, and humid summers do real damage to wood framing over decades. You won’t know which you need until the old window comes out, but we look carefully during the estimate and flag what we expect.
• Window count and sizes. Labor per window drops slightly when you replace 15 windows versus 3. But custom sizes (older homes rarely have today’s standard dimensions) add fabrication costs. A 72-inch by 60-inch picture window isn’t just two small windows’ worth of work. It’s heavier, it needs reinforcement, and it costs more per square foot.
• Neighborhood and historic district requirements. If you’re in a City of San Antonio historic district (King William, Monte Vista, parts of Lavaca), there can be additional review requirements and material restrictions. This adds time and often pushes costs toward wood or wood-look products. We help navigate the paperwork, but the cost is real.

How to Save on New Window Installation

There’s smart saving and there’s false economy. Here’s the real guidance.

• Replace in phases. If you can’t do the whole house at once, do the worst-performing windows first: the ones facing south and west, where San Antonio’s summer sun bakes through after 2 p.m. North-facing windows can usually wait. This spreads the spend over a couple of years without sacrificing energy performance where it hurts most.
• Stick with standard sizes when possible. If a window opening can take a standard size with minimal trim work, that’s cheaper than ordering customs. On ranch-style homes and newer builds, standard sizes are common. On older homes, they’re not. Don’t force a standard size into a nonstandard opening to save $100. You’ll pay for it in air leakage forever after.
• Choose vinyl with low-E and argon, skip triple-glaze. In San Antonio’s climate (hot summers, mild winters, little freezing), triple-glazing is overspending. A good dual-pane low-E vinyl window with argon fill gets you 90% of the performance at 60% of the cost.
• Bundle installation. Labor pricing per window is most efficient when a crew is already on site and set up. Doing 10 windows in one job costs less per window than doing two windows five times across five years. If you’re going to replace them eventually, do them together when you can.
• Get a fixed written quote. This is the one that saves you real money. The biggest cost swings in window installation are surprises: rotted frame discovered after the window comes out, “extra” trim that wasn’t in the original scope, disposal fees added at the end. Our price is in writing before anyone picks up a tool. What we quote is what you pay. If the work isn’t right, our 365-Day Done Right Promise covers you: we make it right, no argument needed.
• Ask about financing before paying cash. A lot of San Antonio homeowners don’t realize how flexible window financing has become. If you can get a reasonable rate, you may not need to save aggressively or defer fixes. We can walk you through what’s available, but the decision never gets pressured.

Window Brands and What They Mean for Your Price

We don’t push one brand. We carry eight professional-grade lines because different San Antonio homes need different things. Here’s how we think about matching product to house.

PGT and CGI are the two we reach for most when impact and wind ratings matter. PGT’s WinGuard line is a vinyl impact window that does the job without the aluminum price tag. CGI makes a heavier aluminum impact window that’s built for larger openings and strict TAS compliance. If you’re on the western edge of Bexar County or anywhere the wind maps get serious, these are the conversation.

CWS and ES Windows are our workhorse residential vinyl and mid-range lines. Solid thermal numbers, good warranties, clean looks. These brands cover most standard replacement jobs in areas like Leon Valley, Shavano Park, and the De Zavala corridor. ECO Window Systems gives us a strong mid-tier option with excellent insulation values for San Antonio’s heat.

Mr-Glass and ViewLux are what we turn to for high-end architectural looks and specialty glass. Large custom openings, modern homes, or a homeowner who wants the glass itself to be the feature. These aren’t budget lines, but they’re the right tool for certain jobs, and we’ll tell you honestly if they’re overkill.

Therma-Tru is the one you’ll hear when we’re doing a door. If you’re replacing windows and your front door at the same time, Therma-Tru’s entry systems pair well with any of the window lines above. We mention this because a lot of homeowners do the windows first and realize the front door is shot too. Bundling both works to your advantage on labor.

Energy Efficiency: What San Antonio Homeowners Should Expect

San Antonio summers are not mild. CPS Energy rates have climbed steadily over the last five years, and your windows are one of the biggest levers on your cooling bill. In our experience replacing windows in older homes here (think 1970s and 1980s construction in areas like Churchill Estates, Oak Hills, and North Central San Antonio), homeowners commonly see 15% to 25% drops in peak summer cooling costs after switching from old single-pane or failed-seal dual-pane windows to modern low-E vinyl or fiberglass.

That’s not a guarantee. It depends on your home’s insulation, roofline, AC age, and how many windows face west. But it’s what we observe on the ground.

The glass package you pick matters more than the frame material for energy. In our climate, we recommend: dual-pane, low-E coating on both panes where available, argon gas fill, and a U-factor of 0.30 or better. Look at the Solar Heat Gain Coefficient (SHGC). San Antonio wants a lower SHGC (around 0.20 to 0.25) because you’re blocking the Texas sun, not trying to capture it.

Every window we install is spec’d for this climate. We don’t sell you a Northeast-optimized window here. We’d rather sell you what works in San Antonio’s heat, even if it’s not the most expensive option on the sheet.

What to Expect During Your Window Installation

Our process starts with the estimate. When you call (361) 348-8929, a live person answers. Always. No voicemail, no callback queue, any hour. You’ll schedule an estimate with us, and here’s what that visit looks like.

Before we arrive, you’ll get the name and photo of the technician coming to your home. That’s our Threshold Standard: every technician is background-checked, identity-verified, uniformed, photo-badged, and pre-announced by name and photo before the visit. When the doorbell rings, you already know who’s there. For a lot of our customers (parents at home with young kids, older homeowners, people who live alone), this is the deciding factor.

During the estimate, we measure every opening, inspect the existing frames for rot or water damage, discuss what you want from the windows (energy savings, curb appeal, security, all of it), and then we hand you a written price. Not a weird verbal range. A number on paper.

If you approve, we schedule installation. Our crew arrives pre-announced, same as the estimator. The work usually takes one to two days for a standard whole-home replacement. We manage disposal of your old windows, and we leave the site clean. Then our 365-Day Done Right Promise kicks in: if something isn’t right within a year, we make it right. You don’t have to argue with us. You call, we fix it.

Every repair we do also carries a written guarantee. If the repair fails, the second visit is free. That’s not a verbal promise. It’s our policy. Spencer Odell holds the team to it.

FAQs – New Window Installation Cost in San Antonio

How much does it cost to replace 10 windows in San Antonio?

Replacing 10 standard-size vinyl windows in San Antonio typically costs $4,500 to $8,000 installed. If you’re choosing fiberglass or impact-rated windows, expect $9,000 to $14,000. Full-frame work on older homes adds $2,500 to $5,000 to that range. Call (361) 348-8929 for an exact quote on your home. Estimates are free.

Is it cheaper to repair or replace a window?

In San Antonio, a standard repair (reglazing, resealing, replacing a sash cord or spring) runs $150 to $450 per window. Replacement runs $450 to $1,400 per window. If the frame is solid and the glass isn’t broken, repair wins. If the seal has failed and the window’s fogged, or the frame shows rot, replacement is usually the better long-term call. We’ll tell you honestly which applies. Written repair guarantee included either way.

Can you install new windows the same week?

Yes, in most cases. Standard in-stock vinyl windows from our regular lines can usually be installed within 3 to 7 days of estimate approval. Custom sizes and impact-rated windows are typically 2 to 4 weeks depending on fabrication. Call (361) 348-8929 and we’ll give you a real schedule.

What does a full-frame window replacement cost in San Antonio?

Full-frame replacement runs $700 to $1,800 per window in San Antonio, including the unit, the tear-out to the studs, new flashing, and interior trim reset. That’s $250 to $500 of labor per opening plus the cost of the window itself. Older neighborhoods like Monte Vista and King William see more full-frame jobs because the original wood framing is often compromised.

Are impact windows worth the cost in San Antonio?

Impact windows add $400 to $900 per window over standard dual-pane vinyl. For homes outside windborne debris zones, they’re optional. For homes inside those zones (parts of far west San Antonio and some Hill Country edges), they’re code-required. If you’re on the edge and weighing it, we’ll run the exact numbers for your address. Call (361) 348-8929 and we’ll tell you straight.

New Window Installation in San Antonio: The Bottom Line

You should leave this page knowing three things.

One: window installation in San Antonio costs $450 to $1,400 per window installed, with most full-home jobs landing between $6,500 and $14,000.

Two: the specific product line, glass package, and installation method drive the price. We carry PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux for exactly this reason. One brand can’t serve every San Antonio home well, and we’d rather match the product to your house than push what’s easy.

Three: a written fixed price is the single best protection against window-project cost overruns. We give you that written number before any work starts, every time. And every job carries our 365-Day Done Right Promise. If the work’s not right, we make it right. No argument needed.
