AfterHow Much Does Window Replacement Cost in San Antonio?
Window replacement in San Antonio typically costs between $4,500 and $15,000 for a full-home project in 2026, with most homeowners paying around $8,500 to $9,000 for 8 to 12 double-paned vinyl windows including labor and disposal. A single standard window replacement runs $450 to $1,200, while a whole-home job with premium materials like fiberglass or impact-rated glass in neighborhoods such as Alamo Heights or Terrell Hills can reach $25,000 or more.
These are real numbers for the San Antonio market, not national averages. Our climate, our home styles, and our labor rates all shape what you’ll actually pay. If you want a written price for your specific home, call (254) 269-5071 for a free estimate with no obligation.

Window Replacement Cost Breakdown (2026)
Here’s what the numbers actually look like in San Antonio right now, broken down by window type and scope. These ranges reflect what we’re seeing across the metro area this year, from Leon Valley to Stone Oak.
| Project Type | Typical Cost Range | Notes |
|---|---|---|
| Single window (vinyl, standard size) | $450 – $1,200 | Includes labor, haul-away, trim |
| Single window (wood or fiberglass) | $900 – $2,500 | Higher material cost, longer install |
| Impact-rated window (per unit) | $1,200 – $3,200 | Laminated glass, heavy-duty frame |
| Full-home replacement (8 – 12 windows, vinyl) | $4,500 – $15,000 | Most common San Antonio job |
| Full-home replacement (premium/impact) | $8,000 – $25,000 | Fiberglass, wood-clad, or storm-rated |
| Glass-only replacement (seal failure) | $200 – $600 per pane | When frame is still in good shape |
| Window screen replacement | $40 – $120 per screen | Aluminum or solar screen |
Labor in San Antonio runs $150 to $400 per window. A straight swap on a single-story brick ranch in Northwest Crossing goes fast and cheap. A second-story window with stucco exterior and rotted framing in Monte Vista takes longer and costs more. That’s normal.
You also need to factor in disposal fees, which most contractors fold into the quote. Old windows, caulk, and trim debris usually add $50 to $150 to a full-home job. If lead paint is present (common in pre-1978 homes in neighborhoods like Jefferson and Beacon Hill), federal rules require containment procedures that add $100 to $300 per opening.
What Affects Window Replacement Pricing in San Antonio
- Window count and size. A 1,200-square-foot mid-century home in Oak Hills might have 8 windows; a two-story custom in The Dominion could have 20 or more, several oversized. Size drives material cost directly.
- Frame material. Vinyl is the value play. Wood and fiberglass look better and last longer but double or triple the per-unit material cost. Composite frames sit in the middle.
- Glass package. Double-pane low-E is now standard in San Antonio. Triple-pane adds $150 – $400 per window but can cut cooling bills noticeably. Given our 95-degree summers, it pays for itself faster here than in most markets.
- Impact rating and hail resistance. San Antonio sits in a hail corridor. If you’re in an area that got hammered in the 2023 storms, your insurance may require impact-rated glass, which runs 40 – 60% above standard. We see this often in Alamo Ranch and Helotes.
- Framing condition. Old San Antonio homes mean old wood framing. If the rough opening is rotted from decades of humidity and heat, repairs add $100 – $350 per window before the new unit goes in. We find this constantly in King William and Lavaca.
- Permit and code requirements. San Antonio code requires egress windows in bedrooms, and if your replacement changes the opening size at all, you’ll need a permit. Straight swaps don’t. Egress upgrades cost $500 – $1,500 per window if you’re bringing a non-conforming bedroom up to code.
Window Replacement vs. Repair: Which Makes More Sense?
If you’ve got fogged glass, a broken sash, or a window that won’t stay up, you don’t always need a full replacement. Glass-only replacement runs $200 to $600 per pane in San Antonio when the frame is sound. A sash replacement costs $250 to $700.
But when the frame itself is warped, rotted, or drafty, patching it is throwing money away. A good rule: if repair costs exceed 50 – 60% of replacement cost, replace it. And if multiple windows are failing, a full-home swap usually beats piecemeal work because you negotiate better material pricing and the crew is already on site.
We don’t upsell full replacement when a repair will genuinely serve you. A written price before any work starts means you’ll see exactly what each option costs and can decide without pressure. That’s standard practice at Mason Remodeling, not a promotional hook.
How to Save on Window Replacement in San Antonio
You don’t have to max out your budget to get good windows. Here’s what actually moves the needle:
- Replace in the off-season. San Antonio contractors get slammed after hail season and before summer. If you schedule a January or February install, you’ll sometimes get 5 – 10% better pricing because crews have open slots. You’ll also avoid the August heat, which slows installs and makes the work harder on everyone.
- Do the whole home at once. Replacing 10 windows in one job is cheaper per window than doing 3 now and 7 later. You’ll pay one setup fee, one disposal charge, and one trip for labor instead of three.
- Keep standard sizes. Changing window dimensions means reframing, which adds $300 – $800 per opening. If the existing size works for you, keep it.
- Skip the extras you don’t need. Grids, custom colors, and obscure specialty glass all add cost without adding energy efficiency. Spend on the glass package, not the aesthetics.
- Get a written price. Verbal estimates that grow on the final bill are the oldest trick in the contractor book. Get the number in writing, with labor and materials separated, before you sign anything. We give every homeowner a written price on every project, every time. No exceptions.

Energy Savings: What New Windows Actually Do for San Antonio Homes
San Antonio summers are brutal. The average household here spends about $1,800 to $2,400 a year on electricity, with cooling eating the biggest share. Replacing single-pane or failed double-pane windows with new low-E double-pane units typically cuts the cooling portion of that bill by 12% to 18%.
In dollar terms, that’s $200 to $400 a year on a typical San Antonio home. If you spend $8,500 on a full replacement, you’re looking at a 20 to 25 year payback from energy alone. That doesn’t include the comfort improvement, the UV protection for your furniture and floors, or the resale value. Buyers in San Antonio notice windows. It’s one of the first things they check in older homes across Mahncke Park and Tobin Hill.
One thing worth knowing: the glass coating matters more than the frame material for energy performance. A mid-grade vinyl window with a good low-E coating will outperform a fancy wood window with builder-grade glass. Spend on the glass, not the nameplate.
If you’re considering a full Window Replacement in San Antonio, we can walk you through the energy numbers for your specific orientation and exposure before you commit to any product.
San Antonio Window Codes and Permits: What You Need to Know
San Antonio follows the International Residential Code with local amendments. For windows, here’s what matters:
- Egress requirements: Every bedroom window must have a minimum clear opening of 5.7 square feet, with at least 24 inches of height and 20 inches of width. If you’re replacing an old window that doesn’t meet this, you’ll need to bring it up to code. This is common in 1950s homes in neighborhoods like Los Angeles Heights and Dellview.
- Permit rules: A straight window-for-window swap with no size change generally doesn’t require a permit in San Antonio. Changing the opening size, adding a window, or doing structural repairs to the framing does. Permits run $50 to $200 depending on the scope.
- Historic district restrictions: If you live in a designated historic district like King William or Monte Vista, you may face additional review for exterior changes, including window styles and materials. Wood windows may be required to match the original character. Plan for this before you buy.
- Impact standards: San Antonio isn’t in a coastal wind zone, so impact window installation isn’t code-mandated everywhere. But if your home sits in a hail-prone corridor or your insurer requires it, you’ll need laminated glass rated for the local wind load.
Who Should You Hire for Window Replacement in San Antonio?
Window replacement is not a casual hire. A bad install leaks water into your walls, voids the manufacturer warranty, and costs more to fix than the original job. In San Antonio’s heat and humidity cycle, poorly flashed windows fail fast.
Here’s what we tell homeowners to look for:
- Written price before work starts. Not a verbal number. Not a “ballpark.” A written price with labor, materials, and scope spelled out. This is how Mason Remodeling has operated since 2004, and we won’t work any other way.
- A real guarantee with real terms. Ask what’s covered, what’s excluded, and for how long. Our 365-Day Done Right Promise covers our workmanship for a full year from completion. If something we installed fails because of our labor, we fix it at no cost to you. If you have any concern about a repair or installation within that year, we’ll send a crew back at no charge, no dispute process.
- Who is actually coming to your home. You should know the name and see the face of every person who shows up at your door. At Mason Remodeling, every crew member is background-checked and identity-verified under The Threshold Standard. You receive the technician’s name and photo before the visit, and they arrive in a clean marked uniform with a photo ID badge at your door. This matters if you’re home alone, you have young kids, or you’ve had a bad experience with contractors before.

What to Expect During Your Window Replacement Project
Window replacement is one of the cleaner remodeling jobs. Here’s how it typically goes in a San Antonio home:
Day 1: Crew arrives, lays drop cloths, removes old windows one at a time. Each opening gets inspected for rot, water damage, or framing issues. If something’s wrong, we’ll show you photos and give you a written price for the fix before we proceed. No surprise add-ons.
Days 1 – 3: New windows go in, get flashed and sealed, and trimmed out. Most full-home jobs wrap in two to three days, though large or complex projects can run longer. We work around your schedule and keep the job site contained so your family can function normally.
Final walkthrough: We walk the project with you, window by window, and you don’t sign off until you’re satisfied. Your written guarantee starts the day we finish, not the day you call with a complaint.
A live person answers our phone 24 hours a day, 7 days a week. If you have a question at 9 p.m. on a Sunday, you’ll reach a human being, not a call tree. That’s part of how we’ve run this business for over 20 years.
FAQs – Window Replacement Cost
How much does it cost to replace windows in a 3-bedroom house in San Antonio?
A typical 3-bedroom, 2-bath San Antonio home has 8 to 12 windows. Full replacement runs $4,500 to $15,000, with most jobs landing around $8,500 to $9,000 for standard vinyl windows. Homes in older neighborhoods with wood framing issues or historic district requirements may push higher. Call (254) 269-5071 for a free written estimate on your specific home.
Is it cheaper to repair or replace windows?
Glass-only repair runs $200 to $600 per pane, which beats replacement if the frame is sound. But if the frame is warped, rotted, or failing, repair costs often exceed 50 – 60% of replacement cost, and replacement is the smarter money. We’ll show you both numbers in writing and let you decide. Estimates are free.
How long does window replacement take in San Antonio?
Most full-home window replacements take 1 to 3 days of on-site work once materials are delivered. Custom-sized windows have a 3 to 8 week lead time in the 2026 San Antonio market, so plan ahead. Emergency board-up or glass repair can often be scheduled within 24 – 48 hours. Call us for current lead times.
Do I need a permit to replace windows in San Antonio?
A straight swap with no size change generally doesn’t require a permit. Changing the opening size, adding a window, or repairing structural framing does. San Antonio permits for this work run $50 to $200. If you live in a historic district like King William, additional review may apply. We handle permitting on every job that requires it.
What are the best windows for San Antonio’s heat?
Double-pane vinyl or fiberglass windows with low-E coatings are the workhorse choice for San Antonio’s climate. Expect to pay $450 to $1,200 per window for quality vinyl, or $900 to $2,500 for fiberglass. Triple-pane adds $150 – $400 per window and makes sense if you plan to stay in the home long-term given our cooling costs. Impact-rated glass is worth considering if you’re in a hail-heavy corridor. Call (254) 269-5071 and we’ll help you match the right product to your home and budget.
