Fast, Reliable Windows & Doors Across Timberwood Park
Window replacement in Timberwood Park typically runs $4,500 to $15,000 for a full-home swap, while impact window installation lands between $8,000 and $25,000 depending on how many openings you have and whether we’re anchoring through Edwards limestone. Most of the work we quote here is done on big custom homes built between the late 1980s and mid-2000s, and the county rules are different than anything a San Antonio contractor is used to. We know that because we do this work in Timberwood Park every season. Call (877) 610-1318 and we’ll walk you through what actually applies to your lot before anyone touches a tape measure.
Why Barrett & Sons Construction Is Timberwood Park’s Preferred Windows & Doors Company
Tom Barrett started this company in 1998, and his sons run the crews you’ll see in Timberwood Park. That’s not a marketing line. When you call, a live person answers, and if something needs fixing after the job, the same people who installed it come back. We publish Tom’s name, address, and license number because the last contractor many Timberwood Park homeowners used didn’t, and that worked out about as well as you’d expect.
We’ve pulled Bexar County permits for window and door work throughout the 78260 zip code, from the big custom lots off Borgfeld Road to the ranch-style homes along Blanco Road. What that means for you is simple: we don’t submit to the wrong jurisdiction, we don’t get surprised by impervious-cover math, and we don’t tell you a permit is optional when the county says otherwise. The permit inspector works for you, not for me. That’s why I like him.
Every scope, every allowance, every price change arrives as a written change order before work happens. If a wide impact slider needs rock-breaking through shallow limestone, that’s on the allowance sheet before you sign, not on an invoice after the concrete’s open. An allowance that isn’t on paper is a surprise waiting for a date. We’d rather have the hard conversation up front.
Our Windows & Doors Services in Timberwood Park
Window Installation
New window installation in Timberwood Park almost always means working around stone veneer exteriors and deep roof overhangs, which are two things standard tract-home crews never deal with. We’ve set hundreds of Simonton and Ply Gem units into Hill Country custom homes here, and we know how to keep the flashing tight against limestone ledgestone without turning your wall into a masonry project. Frame condition, opening size, and whether we’re matching existing trim profiles all affect the quote, and we’ll put every one of those numbers on paper.

Door Installation
Front doors, side entry doors, and French doors on Timberwood Park homes tend to be taller and wider than what you’d find in a production neighborhood, and a lot of them open onto covered patios framed in cedar. That cedar is beautiful until it starts holding water against the threshold, and we see that regularly on homes built up and down the 78260 corridor. Whether you want a single steel entry door or a full custom wood unit, we’ll check the rough opening, the existing header, and the county requirements for the replacement before we give you a number.

Window Replacement
Most Timberwood Park window replacement work lands in the $4,500 to $15,000 range for a typical 2,500 to 5,000 square foot home, with the final figure driven by how many windows you have, whether they’re standard sizes or custom, and what glass package we’re installing. We carry PGT and CGI lines for homeowners who want impact-rated glass, and Simonton for those who don’t need the storm rating but still want a real insulating upgrade from 1980s single-pane aluminum. Every window replacement we quote in Timberwood Park includes a written scope with the exact unit count, glass type, and install method.

Impact Windows & Doors
Timberwood Park sits on the edge of the Balcones Escarpment, and while we don’t get the full Gulf coast hurricane punch, we do get wind-driven hail, hard freezes, and the occasional ice storm that San Antonio proper barely feels. Impact windows and doors are a practical choice here, especially on the large eastern-facing glass walls that are common on Texas Ranch homes in this area. A full impact package for a Timberwood Park home runs $8,000 to $25,000, and the county’s impervious-cover rules can come into play if you’re enlarging any opening for a wider slider or a multi-panel folding door. We handle that calculation before the order goes in, not after demo starts.

Trusted Brands We Service in Timberwood Park
We install Simonton, Ply Gem, PGT, and CGI windows and doors, and we stock common replacement parts and hardware for these lines so Timberwood Park homeowners aren’t waiting on a distributor in Houston. That matters when a PGT impact sash gets cracked by a spring hail cell and you want it ordered before the next storm season. Because our Windows & Doors team runs these products every week, we can tell you honestly which line fits your budget and which is overkill for a north-facing window on a protected wall. We’ll also tell you when a high-end impact package doesn’t make sense, because quoting you the most expensive option isn’t the same as doing right by you.
Common Windows & Doors Problems We See in Timberwood Park Homes
- Water intrusion at patio door thresholds. The cedar-framed covered patios that are so common on later-1980s and 1990s Timberwood Park builds hold moisture against door sills, rotting the subfloor before you ever see it from inside. We’ve opened up enough of these to tell you: if the door sticks when it rains, don’t wait.
- Air leaks around original aluminum windows. Homes built in the late 1980s through the early 1990s often still carry original single-pane aluminum, and the hard freezes we get this far north of the city make those leaks expensive on your heating bill. Replacement in Timberwood Park usually pays back faster than in warmer parts of Bexar County because we actually get winter.
- Failed rollers on heavy sliding glass doors. Big limestone and stucco ranch homes love their 8-foot and 12-foot sliders, and those rollers wear out. We see it constantly, and we stock replacement roller assemblies for the common brands so a $75 part doesn’t turn into a $1,200 door replacement.
- Fogged double-pane glass from failed seals. The temperature swings between our hot afternoons and cold Hill Country nights are hard on double-pane seals, and a fogged unit means the insulating gas is gone. We replace individual sashes whenever the frame is sound, which saves you thousands versus a full-window swap.
Pricing for Windows & Doors in Timberwood Park, TX
Here’s what we actually see on Timberwood Park quotes, not what a national estimator guesses from a picture:

What pushes a Timberwood Park window job toward the top of the range? Wide custom openings that aren’t a standard size off any shelf, impact-rated glass, and any work that requires drilling new header anchors through shallow limestone bedrock. That last one catches out-of-area contractors every single time. We pull the Bexar County permit, run the site-coverage numbers if your opening is growing, and put rock-breaking on the allowance sheet before you sign. That’s the difference between a quote you can take to the bank and a bill you never saw coming. Call (877) 610-1318 for a free estimate, and we’ll walk your specific home line by line.

FAQs - Windows & Doors in Timberwood Park
In most cases, swapping an existing window for a new unit of the same size does not require a Bexar County building permit, because you’re not changing the structure or the opening. But there are exceptions: if the window is part of a load-bearing wall assembly, if you’re changing the rough opening size, or if the home has specific HOA or deed restrictions that require architectural review, you may need documentation. We check the county rules for every Timberwood Park job before we quote, and if a permit is needed, we pull it. Call (877) 610-1318 and we’ll tell you what applies to your specific windows before you commit to anything.
The aquifer rules in Timberwood Park cap impervious cover at 15 to 30 percent of your total lot area, and a new wide sliding glass assembly is considered part of the structure’s footprint. On a big five-acre lot, you usually have room to move. On a smaller Timberwood Park parcel, especially one with an existing large home, detached garage, pool deck, and a long driveway, you can be closer to the cap than you think. If we’re enlarging an opening for a 12-foot impact slider, we run the site-coverage calculation before you order anything. It has saved our Timberwood Park customers from mid-project redesigns more than once. Call us for a free estimate and we’ll run your numbers.
It can add meaningfully to the budget if the work is quoted properly, and it can wreck the budget if it’s ignored until the crew hits rock. Timberwood Park sits on shallow Edwards limestone, and depending on where your home sits, a new French door opening can require hydraulic rock-breaking or diamond-bit drilling for the header anchors and threshold prep. We price that from the start. The cost gets written into the allowance sheet as a line item, so there’s no change order later. If a contractor’s quote for a French door in Timberwood Park doesn’t mention limestone, that’s a red flag. Call (877) 610-1318 for a quote that accounts for the rock before we dig.
Because they submit to the City of San Antonio’s Development Services portal every day, and Timberwood Park is unincorporated Bexar County. The county runs its own permitting through Bexar County Development Services, with different lead times, different inspectors, and different submittal requirements. A contractor who doesn’t know that will either file in the wrong place and stall your schedule for weeks, or tell you the permit isn’t needed at all. Both are bad. We pull Bexar County permits for Timberwood Park work as a matter of course, because the inspector works for you, not for the contractor. That’s the whole point of pulling the permit.
Yes, and we do this regularly for Timberwood Park homeowners who are building a detached guest house or shop and want matching impact windows across the main home and the new structure. Permitting runs through Bexar County, and depending on your lot, you’ll likely need to account for impervious cover on the ADU footprint plus the window and door openings on the existing home. We coordinate both scopes under one written quote so you see every line item before the county ever sees the drawings. Bundling also lets us stage materials more efficiently, because we’re not running two separate mobilizations from the San Antonio office. Call (877) 610-1318 and ask for Tom. He’ll put the whole thing on paper.

On a five-acre custom home off Borgfeld Road in Timberwood Park, our crew replaced a 1960s-era cedar-framed covered patio door with a 12-foot impact sliding glass system. Before quoting, we pulled the Bexar County permit and confirmed the new opening stayed within the impervious-cover allowance, then scheduled diamond-bit drilling for the header anchors through shallow Edwards limestone. No change order was needed, because the allowance sheet spelled out rock-breaking up front.
