How Much Does Window Replacement Cost in San Antonio?

Window Replacement in San Antonio typically costs $450 to $1,400 per window including installation, with most homeowners spending $6,800 to $14,500 for a full-house project of 10 to 15 windows. Vinyl windows run $450 to $900 per opening, while premium impact-rated or fiberglass units land closer to $1,000 to $1,400. These 2026 figures reflect the San Antonio market specifically, where heat, humidity, and hail season shape both product choices and labor rates.

We’re Juniper Windows San Antonio, part of the Relay Home Co. family since 2001. Sean Mackey leads our window and door replacement team here, and every quote we give carries one rule: the price you see is the price on the invoice. No add-ons at the door, no “we found rot” surprises after the old window comes out.

Window Replacement Cost Breakdown (2026)

Here’s what you’ll pay per window in the San Antonio market, broken down by frame material and glass type. These numbers include removal of the old window, installation, trim work, and haul-away:

Labor in San Antonio runs $150 to $350 per window for a straightforward replacement where the existing frame stays put. If the frame is rotted or out of square, you’ll add $100 to $250 per opening for reframing. On the north side around Stone Oak and Rogers Ranch, second-story work and stucco exteriors push labor toward the top of the range. Older neighborhoods like Jefferson and Beacon Hill, where houses date to the 1920s and 1930s, often need custom sizing that adds 15% to 25% per window.

Juniper Windows San Antonio carries eight product lines, including PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That matters for pricing because it means you’re choosing from a range of price points, not being pushed into whatever one brand happens to stock.

Whole-Home Project Ranges

Here’s what a full replacement looks like at typical San Antonio home sizes:

• 8 windows (small 3-bed, 1,200-1,500 sq ft): $3,600 – $8,400
• 12 windows (average 3-bed, 1,700-2,200 sq ft): $5,400 – $13,200
• 18 windows (larger 4-bed, 2,500-3,200 sq ft): $8,100 – $20,700
• 25+ windows (custom or two-story): $14,000 – $35,000+

Most San Antonio homes built between 1980 and 2010 have builder-grade aluminum windows that were installed cheap and are now failing. We regularly replace 12 to 15 windows on these houses, and vinyl double-hungs make up about 70% of what we install in the Alamo Heights, Terrell Hills, and Shavano Park areas.

What Affects Window Replacement Pricing in San Antonio

• Heat and UV exposure. San Antonio sees 220+ sunny days per year, and July highs average 95°F. That makes Low-E coatings and argon gas fills near-essential here, and those add $60 to $120 per window. In practice, most homeowners on the south and west sides of the city (Southtown, Westover Hills) go with a higher-rated Low-E package to cut cooling costs.
• Hail season. Bexar County sits in a hail corridor. Impact-rated glass (built to resist wind-borne debris without shattering) runs 30% to 50% more than standard insulated glass, but it can lower your homeowner’s insurance premium. Some carriers require it for homes in certain zip codes after multiple claim years.
• Frame condition. If the existing window frames are square, dry, and structurally sound, you’re looking at a straightforward pocket replacement. If there’s water damage from years of leaky seals, you’ll pay for reframing and possibly stucco or siding repair, which can add $200 to $400 per window.
• Window count and size. Larger openings (picture windows, bay configurations) cost more per unit. A 6-foot picture window runs $800 to $2,000, while a small bathroom slider might be $350 to $600. Bulk discounts sometimes apply at 10+ windows, but be wary of contractors who slash the per-unit price and inflate labor.
• Historic district rules. Parts of King William, Monte Vista, and Lavaca have preservation overlays requiring wood or wood-clad windows that match the original style. Those windows run $1,100 to $1,800 per unit, and the approval process can add weeks to the timeline.
• Second-story access. Two-story installation adds $50 to $100 per window for equipment and safety setup. If your home is on a slope (common in the Hill Country fringes near Leon Springs and Timberwood Park), expect a little more.

Vinyl vs. Fiberglass vs. Impact-Rated: What Should San Antonio Homeowners Choose?

Vinyl is the workhorse in this market. It holds up to heat, doesn’t warp or rot, and costs the least. We recommend it for about 80% of the homes we quote. Fiberglass steps up when you have large openings or you want a finish that reads as painted wood. Impact-rated glass is the choice when you’re in a hail-prone zip code, when your insurance company requires it, or when you want the quiet and security that a heavier glass package brings. In the Alamo Ranch and Westcreek areas, where new construction density is high and storm claims have been frequent, impact-rated is the fastest-growing category we sell.

Whatever you choose, U-factor matters here. U-factor measures how well the window resists heat transfer. In a San Antonio summer, a window with a U-factor of 0.27 or lower does noticeably more to keep your AC from running nonstop than one at 0.35. That difference shows up on your electric bill within the first summer.

Can You Replace Windows the Same Day in San Antonio?

Yes. For standard pocket replacements on a single-story home, a crew of two to three installers can typically replace 8 to 12 windows in one day. Two-story or custom work takes longer. Juniper Windows San Antonio schedules most full-home projects as one- or two-day jobs, and you’ll have a live arrival time before we show up. That’s the Relay Visibility Guarantee: book in a tap, track your tech, see before-and-after photos, pay from a digital invoice. No four-hour windows. No wondering who’s pulling into your driveway.

How to Save on Window Replacement in San Antonio

• Replace windows in groups. You’ll pay less per window on a 12-window job than on three one-off visits. Crews are already on site, and suppliers price materials better at volume.
• Choose vinyl over aluminum. Vinyl is actually cheaper than aluminum in the current San Antonio market, and it insulates better.
• Ask about energy rebates. CPS Energy periodically runs rebate programs for energy-efficient window upgrades. Eligibility changes, but it’s worth checking before you buy.
• Standardize sizes. If you’re building an addition or doing a full renovation, sticking to standard window dimensions avoids custom-order surcharges of 15% to 25%.
• Get a written quote that won’t move. Juniper Windows San Antonio gives every job a written price before work starts, backed by the 365-Day Done Right Promise. If the job isn’t done right, we make it right for a full year after installation, parts and labor, in writing. Call (903) 488-7019 for a free estimate, and you’ll have the number before we leave the driveway.

Is It Cheaper to Repair or Replace Windows?

In San Antonio, a single-pane glass replacement runs $80 to $200, and a full sash or hardware repair runs $150 to $400. If your window is less than 15 years old and the frame is solid, repair usually wins. But if your window is aluminum, single-pane, drafty, or has a failed seal (fog between the panes), replacement is the better long-term move. A 20-year-old aluminum window in San Antonio has already lived past its useful life. Replacing it with a modern Low-E vinyl window typically pays for itself in energy savings within 5 to 8 years at current CPS Energy rates.

FAQs – Window Replacement Cost in San Antonio

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

Replacing 10 standard vinyl windows in San Antonio costs $4,500 to $9,000 installed. If you choose fiberglass or impact-rated glass, that range moves to $8,500 to $14,000. Call (903) 488-7019 for an exact quote, our estimates are free and the price we give you is the price you’ll pay.

What is the most affordable window replacement option?

Aluminum single-hung windows are the cheapest option at $400 to $750 per window installed, but they perform poorly in San Antonio heat. Vinyl double-hungs at $450 to $900 per window are the better value, and that’s what we recommend for most budget-conscious projects.

How long does window replacement take?

Most standard single-story replacements take one day for 8 to 12 windows. Two-story homes, custom sizing, or historic district work can extend the job to two or three days. Juniper Windows San Antonio gives you a live arrival time and photo updates throughout, so you always know where the job stands.

Do I need a permit for window replacement in San Antonio?

Basic same-size window replacement typically does not require a permit in San Antonio, but any project that changes the rough opening size or involves structural work does. Historic districts like King William and Monte Vista have additional review requirements. We handle that end of it for you and can verify the exact requirements for your address.

Can you replace windows in the summer in San Antonio?

Yes. Heat doesn’t stop the work, though crews typically start at 7 a.m. to beat the peak afternoon temperatures. The bigger consideration is your AC bill during the workday, but each opening is exposed for less than an hour. We install year-round in San Antonio.

What is the 365-Day Done Right Promise?

It’s our written guarantee that covers every completed installation for a full year. If something isn’t right, parts and labor, we make it right. No charge, no argument. If a repair fails, the second visit is free. That’s the Juniper standard, on every window and door we install in San Antonio.
