Tom Barrett started this company in 1998, and he still walks job sites in Leon Valley with his sons running the crews. We know which ranch homes along Bandera Road still have original single-pane aluminum frames. We know which 1960s slabs have heaved enough to throw a rough opening out of square. That’s not something a call center in another state can say.
Why Barrett & Sons Construction Is Leon Valley’s Preferred Windows & Doors Company
Most window and door companies that advertise in Leon Valley are actually running crews out of San Antonio and hoping nobody asks which building department has jurisdiction. We don’t play that game. Every permit on a Leon Valley job gets pulled through Leon Valley City Hall, because that’s what the law requires, and because the inspector works for you, not for us. We like it that way. It keeps everyone honest.
Our reputation in Leon Valley is built on twenty-nine years of showing up, doing the work, and standing behind it with the 90-Day Done Right Promise. It’s written on every contract. If something isn’t right, Tom comes back. One call. No phone tree, no corporate claims department, no runaround.
Calls are answered by a live person around the clock. When a Leon Valley homeowner calls about a binding patio door or a fogged picture window, we can usually have someone out to look within a day or two, depending on the inspection schedule we’re working around. And every quote is a written scope of work with the materials named by brand, the permit fees listed, and the labor allowance spelled out before you sign anything.
We also publish Tom Barrett’s name, address, and license number. Look it up. That’s the point.
Our Windows & Doors Services in Leon Valley
Window Replacement
Replacing windows in a Leon Valley home means dealing with two realities: 1950s to 1970s brick ranch construction and Bexar County’s expansive clay soils. Those original aluminum frames weren’t just single-pane energy hogs. Decades of shrink-swell cycles have twisted the rough openings around them. Our Windows & Doors team re-squares those openings before setting new frames, which is the difference between a window that opens smoothly for twenty years and one that binds by next spring. Typical full-home replacement in Leon Valley runs $4,500 to $15,000 depending on count, glazing, and how much opening correction the slab movement has forced.

Door Installation
Entry doors in Leon Valley take a beating from the same soil movement. Wood thresholds on slab homes wick moisture from the clay underneath, and we routinely find rotted subfloor at front and back entries. We pull the old door, cut out the rot, flash the opening properly, and set a new pre-hung unit that drains water away from the slab instead of into it. Door installation runs from $1,200 to $6,000 depending on the unit, hardware, and the extent of rot repair underneath.

Impact Windows & Doors
Leon Valley sits close enough to the Gulf that salt air rides inland, and homeowners on the western edge of town near Huebner Road feel it more than people realize. Impact windows aren’t just storm protection here. They’re a corrosion answer. We install PGT and CGI impact units with marine-grade hardware that won’t pit the way the original 1960s aluminum did. Full impact window packages in Leon Valley run $8,000 to $25,000. Impact sliding glass doors add another $4,500 to $15,000 depending on width and glass. If you’re in a home with original single-pane aluminum, the jump to impact-rated laminated glass is the single biggest upgrade you can make here.

Custom Windows & Doors
Some Leon Valley homes have odd rough openings. A 1970s ranch might have a narrow sidelight next to the front door that no stock unit fits anymore. A 1950s kitchen might have a picture window with no matching replacement on any shelf. We measure, order, and install custom units for those openings. Custom windows and doors usually add 15 to 30 percent over stock pricing, but the alternative is reframing the wall to fit a standard size, which costs more. If you want an odd opening to stay the way it is, call (877) 610-1318 and we’ll quote the custom route first.

Trusted Brands We Service in Leon Valley
We install Simonton, Ply Gem, and PGT windows, and we carry the hardware and flashing components to service them locally. That means a Leon Valley homeowner with a failed balance on a Simonton double-hung doesn’t wait two weeks for a part from a distributor in Dallas. We keep common replacement parts in stock for the brands we install, and we know which hardware holds up in this specific climate. Salt air near Leon Valley is hard on cheap roller assemblies and untreated steel lintels. We specify stainless and hot-dip galvanized hardware on every exterior application, and we name the hardware in the written scope so you can check exactly what you’re paying for.
Common Windows & Doors Problems We See in Leon Valley Homes
- Corroded aluminum frames from the 1950s through 1970s. Salt air carried inland from the Gulf pits the finish, and the sash channels bind. Windows that once opened with one hand now need two, and the pitting only accelerates once the anodized coating wears through. Replacement is the real fix. Lubricating corroded aluminum buys maybe a season.
- Rotted thresholds and entry-door subfloor on slab homes. The same expansive clay that moves Leon Valley slabs also pushes moisture up under door thresholds. We regularly find soft subfloor when we pull a front door, and we cut it all out before setting the new unit. Nobody does a door replacement over rot and expects it to last.
- Rusted steel lintels above window and door openings. Untreated steel lintels rust above brick veneer, and as the rust expands it can crack the masonry above the opening. We see it on Leon Valley brick ranches constantly. A new window installed under a failing lintel is a window waiting to fail. We replace the lintel as part of the opening correction, not as a surprise add-on later.
- Fogged double-pane glass in early retrofits. Homes that got replacement windows in the 1980s and 1990s now have units with failed seals. The glass is cloudy, and the insulating gas is gone. We replace the sash or the full unit depending on the frame condition, and we keep the old frame only if it’s still square and sound.

FAQs - Windows & Doors in Leon Valley
Yes. Leon Valley is an independent municipality completely encircled by San Antonio, and the city’s Building Department on Bandera Road issues its own permits for window and door replacements when the work involves structural changes, size changes, or impact-rated openings. Some direct same-size replacements don’t require a permit, but the minute you alter an opening or add impact glazing, the city wants to see plans. We pull every required permit for you and coordinate with Leon Valley’s inspection staff, whose schedule is smaller than COSA’s. That’s why early permit submission matters here. Call (877) 610-1318 and we’ll tell you exactly what your specific job requires before you spend a dollar.
It throws rough openings out of square, and it does so unevenly across the same house. Leon Valley sits near the Balcones Escarpment where Hill Country limestone meets deep coastal-plain clay. Drought pulls the soil away from slab footings; wet years heave it back. A window opening that was square in 1970 may be off by half an inch in 2026. If you set a new vinyl frame into that opening without correcting it, the sashes bind, the weatherstripping gaps, and the unit fails early. We check every opening with a level and square before we order a thing, and we re-square what the clay has moved.
Vinyl frames with stainless or hot-dip galvanized hardware outperform the original aluminum that Leon Valley homes got in the 1950s through 1970s. Salt air carried inland corrodes aluminum, pits the finish, and seizes the sashes. Vinyl doesn’t corrode the same way, and when you pair it with marine-grade hardware, it’s the best long-term value for this specific climate. If you want the old aluminum look, there are coated aluminum products that resist pitting better than the originals, but they cost more than vinyl. We’ll quote both and tell you which one gives you more useful years per dollar in Leon Valley.
Yes. Impact-rated windows and doors are considered structural upgrades in Leon Valley, and the city’s Building Department reviews them separately from like-for-like replacements. The glazing package, the anchoring schedule, and the frame rating all have to be documented. It’s the same reason impact quotes sometimes run higher here than in neighboring San Antonio: the permit path is shorter but less forgiving, and the city’s small inspection staff reviews impact installs carefully. We’ve done enough Leon Valley impact installs that we know what the inspectors look for, and we submit those permit packages early so the punch list doesn’t stall.
Because a correct Leon Valley quote includes the city’s own permit fees, the inspection-scheduling buffer, and materials spec’d for the local soil and salt-air conditions. Contractors who quote Leon Valley as if it were COSA jurisdiction eventually discover the permit problem and either eat the cost (rare) or pass it through as a change order after you’ve already signed. Our quotes are higher on the front end because they’re honest on the front end. You won’t get a surprise permit invoice from us. The allowance that isn’t on paper is a surprise waiting for a date.
