That’s how we keep a two-week project from turning into a six-week mess.

Why Juniper Windows San Antonio Is Leon Valley’s Preferred Window Replacement Company
Juniper Windows & Doors has been part of the Relay Home Co. family since 2001, and our San Antonio office dispatches crews to Leon Valley with local familiarity that matters. We’re not a general remodeler. We do windows and doors, full stop. That focus means our techs recognize a failing PGT weatherseal or a Therma-Tru threshold issue the moment they see it.
Homeowners around the 78238 and 78240 ZIP codes call us because they’ve already dealt with contractors who quote low and adjust at the door. That doesn’t happen here. Sean Mackey runs every Leon Valley project under the Relay Visibility Guarantee: you get a live arrival time you can track, photo updates while we work, and a written price before anything gets ordered. Our background-checked, uniformed techs show up when they say they will.
We’ve replaced windows on Poss Road, near Raymond Rimkus Park, and throughout the neighborhoods east of Loop 410 where original single-pane aluminum frames have finally given out. Every Leon Valley job gets the same standard: a fixed price, a permit pulled when the opening requires it, and a one-year written warranty on the install.
Window Replacement Company in Leon Valley
Our Door Replacement in Leon Valley follows the same full-unit approach: we replace the entire window unit – frame, sash, glass, and hardware – not just swapping out a pane. This is the right move when your original 1960s ranch windows have corroded aluminum frames, failed seals, or warped sashes that no longer close tight against a Texas downpour. A full-frame replacement typically runs $1,100 – $2,300 per opening in Leon Valley, with insert replacements landing closer to $650 – $1,400 when the existing frame is still square and solid.
Full Frame Replacement
When we pull an original window on a Leon Valley ranch, we check the rough opening before we order anything. Older slab-on-grade homes settle, especially on the clay soils common here, and a header that was fine in 1972 may not pass today’s code for a wider opening. We write any hidden framing repair into the contract as an allowance, and we don’t spend a dollar beyond that allowance until you’ve approved the number in writing.
Insert Window Replacement
If your frames are solid but the glass is shot, an insert replacement keeps the existing frame and drops a new window into the opening. In Leon Valley’s 1980s brick veneer houses, we often find builder-grade frames that are still square, making inserts a clean $650 – $1,200-per-window option. The caveat: if there’s dry rot or a bent jamb from someone forcing a stuck sash, we’ll tell you before we start, because an insert won’t fix that.
Window Glass Replacement in Leon Valley
Window Glass Replacement in Leon Valley is what you need when the pane is cracked, fogged, or shattered but the frame itself is still in good shape. A standard double-pane insulated glass unit runs $250 – $550 per pane here, though impact-rated glass from PGT or CGI pushes that to $450 – $850 depending on size and thickness. If the frame is aluminum and heavily corroded – which happens fast in Leon Valley’s humid summers – glass replacement alone is often a temporary fix.
Low-E and Impact-Rated Glass
Leon Valley’s hot, humid weather puts real stress on window seals. A low-E coating slows radiant heat transfer, and in homes with serious afternoon sun on west-facing walls, going from single-pane to low-E insulated glass will change how the room feels by late July. Impact-rated glass adds laminated strength – built to resist wind-borne debris – and matters most on homes near open fields where severe thunderstorms push straight-line winds.
When Glass Replacement Isn’t Enough
Original jalousie and awning windows on older Leon Valley back porches are a perfect example. The glass louvers are rarely the only failure. The aluminum frames rot where they meet the slab, the hardware seizes, and no replacement glass in the world fixes a corroded frame. In those cases, we’ll quote both options honestly: patch it now, or replace the whole unit and stop the leak permanently.
Trusted Brands We Service in Leon Valley
We carry and install eight product lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. For Leon Valley homes specifically, we use a lot of Leon Valley PGT casements for back porches, Therma-Tru doors where a builder-grade slider has failed, and ViewLux inserts for brick veneer houses that need a clean replacement without tearing out the exterior. Stocking local parts means a faster turnaround – when your glass spec is already in our San Antonio warehouse, we’re not waiting on a distributor to ship it down I-35.
Common Window Replacement Problems We See in Leon Valley Homes
- Corroded jalousie frames on back porches: The aluminum rusts where it meets the concrete slab, and once the louvers warp, no replacement hardware exists. This is the most common call we get from homes built in the 1960s and 1970s off Evers and Poss Roads.
- Swollen sashes in 1980s brick veneer homes: Humidity makes the wood or vinyl swell until the sash jams. Homeowners force it, the glass cracks, and the jamb bends. We see this pattern throughout the neighborhoods west of Bandera Road.
- Failed sliding glass door weatherstripping: The original builder-grade sliders lose their seal over time, and the first hard rain tracks water under the slab into the adjacent carpet. Replacing the door and addressing the threshold drainage is a standard fix.
- Undersized headers above wide openings: On older Leon Valley ranches, the window header above a wide replacement opening may not meet today’s code. The inspector makes us reframe before we set the new unit, which is why we write a framing allowance into every full-frame quote.
Pricing for Window Replacement in Leon Valley, TX
Here’s the honest range for window replacement in Leon Valley. A vinyl insert replacement runs $650 – $1,400 per window. Full-frame replacement lands between $1,100 and $2,300 per opening.

FAQs About Window Replacement in Leon Valley
Yes, often. When you pull jalousie windows on older Leon Valley homes, the new unit has to meet current code for the rough opening. That can mean reframing with a properly sized header, and if the wall is load-bearing, the inspector will want to see the engineering before we set the window. We handle the permit, the coordination, and the reframing as part of the job, and any additional framing cost is priced and approved in writing before we start. Call (903) 488-7019 to talk through your specific opening.
Sometimes. Leon Valley sits over the Edwards Aquifer Recharge Zone, and any window replacement that disturbs exterior walls can trigger the city’s impervious cover and stormwater rules. We coordinate with local inspectors on drainage and site runoff before we order glass, so your permit doesn’t stall. A crew from Helotes or Balcones Heights might not think to check – we live with this every week. If your project touches exterior walls, we’ll flag the stormwater requirement at the estimate.
Yes. Leon Valley’s hot, humid summers force air conditioners to run hard, and single-pane aluminum windows transfer heat directly. Switching to low-E insulated glass – or impact-rated laminated glass – cuts radiant heat gain and reduces the load on your AC. The biggest savings show on west-facing walls and old rear-porch windows where direct afternoon sun hits hardest. A written line-item quote will show the glass package cost, and we never pad it with vague language. Call (903) 488-7019 for exact numbers.
You can replace just the glass if the aluminum frames are still solid, but on many Leon Valley homes they aren’t. Years of humidity and slab contact corrode the frames at the base, and once the operable hardware seizes, no replacement parts exist. If we open it up and find the frame is shot, we’ll tell you before we spend a dollar – and we’ll write the full replacement quote so you can compare both options side by side.
We write a framing allowance into every full-frame replacement contract in Leon Valley. If we open the wall and find dry rot, a failed header, or corroded king studs, we stop, photograph the issue, and put a specific dollar number in front of you for the repair. Nothing gets spent beyond the original written price until you’ve signed off. That’s the 365-Day Done Right Promise in action – the price is real, the surprises are handled in writing, and the work gets finished properly.
Why the Aquifer Matters for Your Window Replacement in Leon Valley
Leon Valley sits directly over the Edwards Aquifer Recharge Zone. That single fact changes how window replacements get quoted and permitted here. Any project that disturbs exterior walls can trigger the city’s strict impervious cover and stormwater rules, which means we coordinate with local inspectors on drainage and site runoff before we even order glass. You won’t get that from a crew that works everywhere across Bexar County and nowhere in particular. We plan for it.
Here’s a typical Leon Valley job. We were called to a 1972 ranch on Poss Road after a severe thunderstorm had water streaming through the original jalousie windows on the back porch. Our tech found the aluminum frames had corroded where they met the slab, and the operable louvers were so warped no replacement hardware exists. We wrote an allowance for hidden framing repair into the contract, pulled the permit, and when we opened the wall we found the king studs had dry rot from decades of seepage. We priced the new PT lumber and flashing in writing, got the homeowner’s sign-off, and finished with impact-rated PGT casements that finally sealed the porch. That’s how it goes when you work on 50-year-old slab homes over an aquifer.
Juniper Windows & Doors carries a fitting name. A juniper is a hardy evergreen built to handle sun, wind, and cold – exactly what windows and doors in Leon Valley have to endure.

Sean Mackey runs every project under one standard: a written price before a single screw turns, backed by the 365-Day Done Right Promise.
