Windows & Doors Cost Breakdown (2026)
Here’s what we see across San Antonio neighborhoods from Alamo Heights to Stone Oak to Helotes. These are installed prices, including labor, materials, haul-away of the old unit, and a walkthrough before the crew leaves.
| Project | Typical Price Range (Installed) | Notes |
|---|---|---|
| Vinyl double-hung window, standard size | $450 – $750 per window | Most common replacement; white vinyl, single tilt-in sash |
| Vinyl casement or picture window | $550 – $900 per window | Larger glass area, fixed or crank-out |
| Fiberglass or composite window | $800 – $1,300 per window | Holds tighter tolerances in South Texas heat |
| Impact-rated window (hail/wind) | $900 – $1,500 per window | PGT or CGI; common in areas hit by recent hail storms |
| Custom shape, bay, or bow window | $2,500 – $6,500 total | Includes structural support, interior seat, exterior trim |
| Sliding patio door, 6-foot | $1,400 – $2,800 | Vinyl or aluminum; two-panel |
| French patio door, 6-foot outswing | $2,000 – $3,800 | Fiberglass or wood; includes weatherstripping for our storms |
| Entry door, steel | $900 – $1,700 | Paintable, solid core; good security baseline |
| Entry door, fiberglass with glass inserts | $1,500 – $3,000 | Therma-Tru options; wood-look grain that holds up to heat |
| Custom wood entry door or iron accents | $3,000 – $6,000 | Expect lead time; San Antonio heat demands sealed finishes |
| Full-house window replacement (10 windows) | $6,000 – $15,000 | Depends on material, glass package, and access |
These numbers aren’t pulled from a national database. They reflect what Keith Yamada and the Lightwell team have quoted across San Antonio in the last year. North of Loop 1604, labor runs slightly higher because crews are driving farther. Inside the 410 loop, older homes frequently need trim repair or slight opening adjustments, which adds $75 to $150 per window when it happens.
What Makes the Price Move Up or Down
Two identical houses across the street from each other can carry different window quotes. Here’s the honest version of why.
- Glass package: Single-pane glass is gone in this market. A basic double-pane clear glass runs $450 to $600 per window. Low-E with argon gas, which you’ll want given our August days, adds $60 to $120 per window. Triple-pane is available but rarely the right call in San Antonio unless you’re on a noisy corridor like I-10 or Bandera Road.
- Frame material: Vinyl is the value baseline. Fiberglass and composite hold up better through temperature swings. In neighborhoods like Terrell Hills or Olmos Park where the homes are older and the architecture matters, composite or wood-clad windows often fit the home better than white vinyl.
- Impact rating: If your section of San Antonio has seen hail in the last decade, and that’s most of us, impact-rated glass from PGT or CGI is a real conversation. It runs 35 to 50 percent more than standard glass, but it changes what your insurance conversation looks like.
- Second-story access: Ladder work or a lift adds $50 to $100 per window. Interior access matters too: if furniture has to move, our crew asks before touching anything, and the written quote accounts for that time.
- Old window condition: Rotted wood frames in older homes, common in Alamo Heights, King William, and Monticello Park, mean more prep time before the new window goes in. That’s a $100 to $250 per opening difference.
What Affects Windows & Doors Pricing in San Antonio
San Antonio isn’t Dallas or Houston. Our pricing is shaped by things that don’t apply 200 miles north. Here are the factors that actually move your quote in this market.
- Heat and UV exposure: A west-facing wall in San Antonio gets brutal afternoon sun from April through October. Windows on those elevations need a better low-E coating than north-facing windows. We specify per opening, not per house, which keeps the quote honest.
- Hail history: The 2021 and 2023 hail storms changed what homeowners ask for. Impact glass used to be a coastal product. Now it’s a San Antonio product. The price difference is real, but so is the reduction in replaced-glass calls after the next storm.
- Humidity and seal failure: Failed seals show up as fogged glass, and we see a lot of it in San Antonio because humidity swings stress older units. Replacing the sash is cheaper than the full window ($250 to $450 per sash), but if the frames are tired, the full replacement is the better spend.
- Home age and framing: A 1980s house in Deerfield or a 1950s cottage in Jefferson means different framing around the opening. Newer construction has square openings. Older homes settle. We measure every opening before quoting, not after.
- Door exposure: Entry doors on the south and west sides of San Antonio homes take a beating from sun. A steel door without an overhang fades quickly. Fiberglass holds up better and accepts a wood-grain finish that looks right in a place like Terrell Hills.
- Permit and HOA requirements: Some San Antonio HOAs, particularly in newer developments around Cibolo and Schertz, have architectural review rules for window style and door finishes. We handle that paperwork, and it’s included when relevant.
What You Actually Get for the Money
Price is one number. What you get with it matters just as much. Here’s what every Lightwell job includes, because this is the part that gets missed when comparing quotes line by line.
Drop cloths and shoe covers before the first window comes out. Your floors, rugs, furniture, and the path from the front door to every work area get protected. We take a photo of the cleanup before the crew leaves. If your kids or pets are home, the crew respects quiet hours and keeps tools contained. Where pet-safe caulk and sealants are an option, we use them.
A written price before any work starts. That’s the Cedarwell Care Promise, and it’s been the operating rule since 2010. Not an estimate with an asterisk. A written number. If the job reveals something behind the wall that we couldn’t see, we stop and explain before spending another dollar. You approve before we proceed.
Background-checked, uniformed technicians. You know who’s at your door before they knock, because we tell you who’s coming. The crew follows four things on every visit: 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. Those are the C.A.R.E. values, and they’re not optional.
The 365-Day Done Right Promise. If the finished work isn’t right, we make it right. A year to flag anything, no debate, no countdown. That’s on every job, including the ones with eight windows and the ones with one.
Eight brands, one recommendation. We carry PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That lineup exists so the recommendation fits your house and your budget, not our warehouse. If a fiberglass Therma-Tru door is right for your entry and vinyl PGT windows are right for the bedrooms, that’s what we quote.
Keith Yamada puts it this way: a light well is the architectural opening that pulls daylight deep into a building. That’s what a well-installed window should do for your home. The product matters, but the installation is what makes the light work.
How to Save on Windows & Doors Without Cutting Corners
You don’t have to overspend to get good windows in San Antonio. You also don’t want to under-spend and live with drafty frames for two decades. Here’s where savings are real and where they’re not.
Replace in Phases, Not All at Once
If the full-house number is too much this year, replace the worst elevations first. In San Antonio, that’s usually the west and south sides. Those windows take the most heat load and usually fail first. You’ll see the comfort difference immediately, and the rest of the house can wait six months without harming anything.
Match the Material to the Wall, Not the Whole House
Vinyl in the back bedrooms and fiberglass on the front elevation is a legitimate specification. The front of the house carries the curb appeal. The back of the house carries the utility. We quote it that way when budget matters.
Skip Triple-Pane Unless You Have a Noise Problem
Triple-pane glass adds 20 to 30 percent to glass cost. In San Antonio, the energy argument for triple-pane is weaker than in Minnesota. If you’re near a loud corridor – say, a house backing up to 1604 or under the flight path near Lackland – the noise reduction is worth it. Otherwise, good double-pane low-E with argon is the value point.
Watch the Hardware on Doors
Door hardware is where quotes quietly inflate. A solid deadbolt and a good handleset can be $150 to $400. Decorative glass inserts and custom finishes can push $800. It’s money spent, but it’s also the part you touch every day. We’ll show you options at both ends without pressure.
Don’t Wait for the Next Hail Storm
When storm season hits, lead times stretch for everyone in town. Booking replacement in the off season, late fall or early spring, often means more flexible scheduling and the same pricing. It also means you’re not part of the post-storm rush competing for glass.
If you want us to look at your home and give you a real number, call (325) 420-4173. Estimates are free and the written quote is yours to keep, whether you hire us or not.
How Much Does It Cost to Replace One Window in San Antonio?
A single standard-size vinyl window replacement in San Antonio runs $450 to $750 installed, including removal of the old unit, new window, interior trim work, and haul-away. If the window is large, on the second floor, or needs impact-rated glass, expect $800 to $1,500 for that single opening. One-window jobs are perfectly fine to quote and schedule with us. Call (325) 420-4173 for a written price on your specific window.
Is It Cheaper to Repair or Replace Windows in San Antonio?
For a single issue like fogged glass or a broken sash, repair runs $250 to $450 per sash, while a full replacement runs $450 to $1,200 per window. If the window is under 15 years old and the frame is square, repair is the cheaper call. If the frame has rot, the seal has failed on multiple panes, or the window predates modern low-E glass, replacement is almost always the better long-term spend in San Antonio’s heat. We’ll tell you which one we’d pick for our own house.
How Much Does an Entry Door Cost in San Antonio?
Steel entry doors run $900 to $1,700 installed. Fiberglass doors with glass inserts run $1,500 to $3,000, and they’re the most common choice in San Antonio because they handle sun exposure without warping. Custom wood doors or iron-accented entries start at $3,000 and run to $6,000+ depending on size and finish. Therma-Tru fiberglass options can be painted or stained to match the house, which matters in established neighborhoods like Monte Vista.
How Long Does Window Replacement Take in San Antonio?
Most full-house window replacements in San Antonio take 1 to 2 days for a crew of two to three. A single window is a half-day job. Entry door replacement is usually 4 to 6 hours, including trim, hardware, and weatherproofing. We protect floors and furniture before starting, and the crew walks the home with you before leaving to confirm every opening is clean and operational.
Do You Offer Same-Day or Emergency Window Replacement in San Antonio?
We answer the phone 24/7 and can often quote same-day. Actual same-day installation depends on product availability and the specific window size. After a storm or a break-in, we prioritize getting a board-up or temporary seal in place first, then install the permanent replacement as soon as the right unit arrives. Call (325) 420-4173 and a live person will pick up, not a recording.
Write Your Own Quote – One Number at a Time
If you want to know what a whole-house project will run before anyone walks the property, here’s a quick path.
Start with the window count. Multiply by $600 for vinyl on a standard one-story home, or $950 for fiberglass. Add $250 to $400 per window on a two-story if ladder access is needed. Add $350 per window if you’re within a hail zone and want impact glass. Add $100 per window if the house is pre-1980 and the frames need correction. That gets you in the ballpark for San Antonio pricing.
Then call us. The written quote is free, and it’s the number that actually matters.
Final Word
You’re hiring a company to cut holes in the outside of your house, even if only for a few hours. You might as well know what the bill says before the saw starts. That’s the entire idea behind no-hassle upfront pricing and the written quote rule.
We protect your floors, your furniture, your kids’ sleep schedules, and your pets’ quiet spots. We clean up before we leave and we photograph the cleanup. And then we stand behind the work for a full year with the 365-Day Done Right Promise.
