Window Replacement in San Antonio - Free In-Home Measure, Written Price

Trusted Window Replacement for San Antonio Homeowners

Our Window Replacement cost guide breaks down why San Antonio projects typically run $450 – $1,200 per window for standard vinyl units, with full-home jobs reaching $7,000 – $22,000 depending on glass packages, framing material, and installation complexity. Most single-window swaps take a day; whole-home replacements usually wrap in two to four days. At Juniper Windows San Antonio, we’ve installed and replaced windows across Bexar County since 2001, and we do it with a written price locked before work begins. If a window is fogged, drafty, or hard to open, call (903) 488-7019 for a free estimate that won’t change at the door.

Energy Efficient Windows

Energy Efficient Windows in San Antonio are not a luxury add-on; they’re the difference between an electric bill that stings in August and one you don’t dread opening. These units use low-emissivity (Low-E) coatings, argon or krypton gas fills, and insulated frames to slow heat transfer. In a city where triple-digit afternoons run from June through September, a well-rated window with a U-factor of 0.27 or lower can cut solar heat gain by up to 50% compared to older single-pane glass. Juniper Windows San Antonio installs energy efficient replacements starting around $450 per window for standard vinyl, with premium packages climbing to $1,200 per unit. The written quote you get includes the exact glass package, the frame material, and the labor.

Low-E Glass and U-Factor Explained

Low-E is a microscopically thin metallic coating that reflects infrared heat while letting visible light through. You get the view without the bake. U-factor measures how well a window resists heat flow; lower is better, and San Antonio’s climate calls for 0.30 or below on most elevations.

When Older Windows Cost More Than New Ones

Single-pane aluminum windows, common in homes built before 1990 around Castle Hills and Alamo Heights, leak so much air that replacing them often pays for itself in under five years. Drafty frames force your AC to work overtime, and that’s a bill you pay every month. We calculate the payback honestly during the estimate: if replacement makes financial sense, we’ll say so. If a seal repair saves you money now, we’ll recommend that instead.

Window Repair

Window Repair is the fix for hardware that’s failing, wood that’s rotting, or tracks that bind, and it’s what we recommend when the glass and frame are still doing their job. In San Antonio, window repair typically runs $120 – $400 per window depending on what’s broken. A simple hardware swap on a double-hung sash runs on the lower end. A rotted sill or a spring-and-balance system replacement lands higher. Juniper Windows San Antonio handles the repair in one visit, with the cost confirmed in writing before anything is disassembled. Sean Mackey set the standard on this: no part gets touched until you’ve seen the price.

Common Repairs We See in San Antonio Homes

Balances and springs wear out, especially on windows facing the afternoon sun in Fair Oaks Ranch and Scenic Oaks. Lock mechanisms corrode from humidity. When the fix is straightforward, we repair rather than replace. It’s faster and keeps money in your pocket.

Repair vs. Replacement: When It’s a Toss-Up

If a window is over 20 years old and the repair quote crosses $350, replacement often makes more sense. A new Energy Star unit gives you better thermal performance and a fresh warranty. We’ll walk you through both numbers so the decision is based on math, not guesswork.

Window Replacement Company

A Window Replacement Company should do three things well: show up when promised, quote a fixed price in writing, and stand behind the work for longer than a handshake. Juniper Windows San Antonio does all three. Founded in 2001 inside the Relay Home Co. family, we specialize in window replacement, window installation, and door replacement, and nothing else. No bathroom remodels, no kitchen additions. That focus means our techs have seen nearly every window problem in San Antonio, from settling foundations in Floresville to sun-blasted frames in Window Replacement in Converse. Full replacements run $450 – $1,200 per window, and the price we quote is the price you pay, regardless of what we find once the old window comes out.

Background-Checked and Uniformed

Every technician who arrives at your door has passed a background check and wears a Juniper uniform. You’ll know exactly who’s walking into your home before they ring the bell. That’s part of The Relay Standard: a live arrival time, photo updates, and a digital invoice you can pay from your phone.

Eight Product Lines, No Compromise Games

We carry PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. Different projects need different products; we match the window to the problem instead of forcing one brand on every job. If impact-rated glass is the right call for a west-facing wall, we’ll say so. If a standard insulated unit does the job, you won’t be upsold.

Window Glass Replacement

Window Glass Replacement is the fix for a cracked pane, a shattered patio door insert, or glass that’s so scratched or fogged it can’t be restored. In San Antonio, replacing glass only, without changing the frame, typically costs $150 – $350 per pane for standard insulated units. The price depends on the glass type: single-strength pane replacements start lower, while Low-E argon-filled insulated units run higher. Juniper Windows San Antonio stocks common glass sizes and orders custom cuts for the rest, usually within three to five business days. The frame stays put, which means less mess, less cost, and a faster turnaround than a full window swap.

Insulated Glass Units, Rebuilt

When a sealed double-pane unit fails and fogs between the glass, we replace the entire insulated glass unit (IGU), not just one pane. An IGU includes the spacer, desiccant, and gas fill; rebuilding it correctly requires cleaning the cavity and sealing it against San Antonio’s humidity. We do that in a controlled shop setting, not on your lawn.

Impact-Rated Glass for Storm Season

For homes in Windcrest and northeast San Antonio, where windborne debris from thunderstorms is a real risk, impact-rated glass makes sense. It’s built to resist projectiles without shattering into dangerous shards. We install ViewLux and PGT impact lines for homeowners who want the extra layer of protection.

Window Sash Replacement

Window Sash Replacement replaces the moving frame that holds the glass, while the outer window frame stays in place. It’s a smart fix when the sash itself is rotted, warped, or permanently fogged. In San Antonio, replacing a sash typically runs $250 – $500 per window, depending on the material and whether it’s a single or double sash job. Juniper Windows San Antonio rebuilds sashes with new balances, weatherstripping, and glass as a single unit. The result looks and operates like a new window, at roughly half the cost of a full replacement.

Wood vs. Vinyl Sashes

Older homes in Terrell Hills and Alamo Heights have wood sashes that swell and stick in humid months. Vinyl sashes, common in homes built after 1990, crack from UV exposure over time. We repair or replace both, matching the existing frame color and hardware as closely as possible.

Balances and Operation Restored

A sash that slams shut or won’t stay up usually has failed spring balances. Replacing the balances during a sash rebuild gives you smooth one-handed operation again. We test every sash through ten full open-and-close cycles before we call the job done.

Window Glass Repair

Window Glass Repair addresses damage to the glass itself: chips, cracks, scratches, and small impact points that haven’t yet spread. In San Antonio, we assess every crack honestly, because not all glass can be saved. Small chips smaller than a quarter can sometimes be stabilized with resin injection, which runs $75 – $150. Longer cracks, or any crack that reaches the frame edge, usually mean a glass replacement instead. Juniper Windows San Antonio gives you the straight answer: if repair is temporary and replacement is inevitable, we tell you that upfront so you don’t spend money twice.

When a Chip Is Fixable

Heat makes cracks grow. San Antonio’s afternoon sun on a south-facing window can turn a tiny chip into a full-length crack in a matter of days. If the damage is caught early and the glass isn’t tempered, a resin fill can restore structural stability and keep moisture out of the pane.

Tempered Glass and Safety Codes

Windows near doors, in bathrooms, or in any low sill position must be tempered under Texas building code. Tempered glass can’t be repaired; once it’s compromised, it must be replaced. If you’re not sure whether your damaged window is tempered, call (903) 488-7019 and we’ll confirm it during the estimate.

Window Pane Replacement

Window Pane Replacement is the service for a single broken pane inside an otherwise healthy window. In San Antonio, replacing one pane in a single-pane window costs $100 – $250. If the window is double-pane and both panes are intact but the unit is fogged, we replace the full IGU, which runs $150 – $350. Juniper Windows San Antonio treats pane replacement as a surgical fix: we remove the old glazing compound, scrape and clean the channel, set the new pane in fresh glazing, and let it cure properly. No shortcuts, no smeared caulk.

Single-Pane vs. Double-Pane Decisions

If you have single-pane windows and one pane breaks, we’ll quote the pane replacement as asked. But we’ll also tell you what a double-pane upgrade would cost. In San Antonio’s climate, the annual energy savings usually favor the upgrade, and the difference in comfort is immediate.

Code-Required Tempered Replacement

Any pane that sits within 18 inches of the floor or within 24 inches of a door must be replaced with tempered glass to meet Texas code. We pull permits when required and pass inspections, every time. That’s standard practice for us, not an upsell.

Window Seal Repair

Window Seal Repair addresses the failure of the seal around the glass, the frame, or both. When the seal on an insulated glass unit fails, moisture gets between the panes and you get that permanent fog clouding the view. In San Antonio, resealing a window frame runs $80 – $200 if the glass is intact and only the perimeter seal is failing. If the IGU seal itself has failed, the fix is a glass unit replacement at $150 – $350. Juniper Windows San Antonio diagnoses which seal is failing before recommending anything, because replacing the wrong part fixes nothing.

Frame Seal Leaks and Drafts

An exterior window seal that’s pulling away from the stucco or brick lets hot, humid air into the wall cavity. That’s a moisture problem waiting to happen. We re-seal exterior perimeters with commercial-grade caulk rated for San Antonio’s temperature swings, which can hit 40 degrees between morning and afternoon in the shoulder seasons.

IGU Seal Failure Diagnosis

Fog between panes means the desiccant inside the spacer is saturated and the gas fill has been lost. There’s no way to re-seal that unit in the field and restore the original thermal performance. We’ll confirm with a moisture meter and give you a straight quote for an IGU replacement, typically done in under an hour per window.

Brands We Service

We replace and service ECO Window Systems windows across San Antonio, including their impact-rated and energy star lines. Their aluminum frames hold up well to Bexar County heat, and we stock their common glass sizes and hardware for same-week turnaround.

Mr-Glass and ViewLux units show up often in homes around Kirby and Leon Valley, especially newer construction from the last decade. We keep OEM replacement parts for both brands in our San Antonio warehouse, so a broken latch or failed balance doesn’t mean a full window replacement. Whether you have ECO Window Systems, Mr-Glass, ViewLux, or any other make, we can help.

Signs You Need a Pro Right Now

• Fog between the panes. The seal on your insulated glass unit is dead. Moisture is inside, the argon or krypton fill is gone, and the window’s insulating ability is roughly cut in half. This doesn’t get better on its own.
• Drafts you can feel. If you can feel air moving around a closed window on a windy day, you’re paying to cool the outside. Failed weatherstripping and broken seals are the usual culprits, and both are fixable without a full replacement in most cases.
• Sashes that stick or slam. A window that fights you when you open it is telling you the balances, tracks, or both are failing. It’s also a safety risk, especially for kids’ bedrooms where an emergency exit matters.
• Visible rot or soft wood. Around Terrell Hills and Alamo Heights, wood-framed windows absorb moisture from San Antonio’s humid springs. Soft sills spread rot into the wall framing if left alone. This needs a pro evaluation before it becomes a structural problem.
• Condensation that never clears. Interior condensation on a regular basis means the glass surface is too cold, which means the thermal barrier is compromised. It’s a sign of failing glass efficiency, not just humidity in the house.
