Call (325) 420-4173 for a written quote before anything gets ordered.
We know Timberwood Park’s older custom homes. We know the west-facing walls off Borgfeld Road that bake in the afternoon. We know the septic drain fields that dictate where a lift can and cannot sit. That local knowledge changes how we stage a job, how long it takes, and what it costs. If you’re replacing windows on acreage, you need a crew that has worked on county land before. We have.
Why Lightwell Windows San Antonio Is Timberwood Park’s Preferred Window Installation Company
Lightwell Windows & Doors is an independently owned Cedarwell location, led by Keith Yamada, and we’ve operated to the Cedarwell Care Promise since 2010. That promise is simple: shoe covers and drop cloths on every visit, a photo of the clean-up before the crew leaves, a written price before any work starts, and a live person answering the phone 24/7. For Timberwood Park families with kids and pets, the drop cloths and pet-safe sealants aren’t extras. They’re the reason you don’t hesitate to book.
Our technicians are background-checked and uniformed, and they follow the C.A.R.E. values on every job: Clean up like it’s our own home, Ask before we move or touch anything, Respect the family’s time and quiet hours, Explain the price before the work. On a Timberwood Park property with a long driveway and a septic field, that means asking where to park the truck, keeping the lift off the drain field, and making sure the gate stays closed so the dog doesn’t wander.
We carry eight manufacturer brands, including PGT, CGI, and Therma-Tru, so we recommend the window that fits the house and the sun exposure, not the one we happen to have in the warehouse. For a west-facing wall with no shade, that’s a low SHGC glass package. For a bedroom that catches morning light, it might be a picture window with a fixed panel. You get the recommendation before you get the price.

Bay Window Installation in Timberwood Park
Bay window installation in Timberwood Park typically runs $3,800 to $7,500 depending on the number of panels and whether we’re doing a retrofit into an existing opening or building out a new bump-out with a roof and knee braces. The first thing we check on a Timberwood Park home is what’s underneath: a bay window over a stone veneer wall needs flashing details that a flat wall doesn’t, and the extra weight means the header and floor framing have to carry more load. On an unincorporated county lot, that often triggers a structural review during the Bexar County permit process.
What a Bay Window Job Includes
We build the seat board, angle the side panels to match the roof projection, and flash every seam before the window goes in. If the home has stone or brick veneer, we cut back the veneer cleanly and install a sill pan that drains water away from the framing. On a bay window facing west in Timberwood Park, we strongly recommend a heat-reflective coating. Afternoon sun through three panels of uncoated glass turns that corner into an oven.
When a Bay Window Makes Sense Here
Timberwood Park homes from the 1990s and early 2000s often have a breakfast nook or a front sitting room where a bay window was either never installed or the original one has lost its seal. If you can see fog between the panes or the window no longer opens smoothly, replacing the whole bay is usually cheaper than repairing three or four individual sashes. We price it as one unit so you know the number before we order materials.
Window Contractor in Timberwood Park
A window contractor in Timberwood Park has to handle more than the window itself. We pull Bexar County permits, schedule inspections around septic setback lines, and plan equipment access around well heads, outbuildings, and long gravel drives. Most replacement window jobs on a half-acre lot take two to four days total, but the scheduling around inspections can stretch that if the county office is backed up. We tell you the realistic timeline in the quote, not a best-case number.
What Full-Frame Replacement Involves
On a 1998 custom home off Borgfeld Road, we recently pulled and replaced a 12-foot expanse of west-facing windows where the original insulated glass units had lost their Low-E coating and the vinyl jambs had warped from years of afternoon sun. We pulled permits through Bexar County, kept the lift clear of the septic drain field, and installed PGT impact-rated casements with a 0.21 SHGC. The homeowner’s afternoon heat gain dropped noticeably, and the wind load rating met code for an open lot with no windbreak.
Retrofits vs. Full-Frame on County Land
If the original frames are square and dry, a retrofit can save you 30 to 40 percent, and it means we don’t touch the interior trim or the exterior veneer. If the frames have warped, or we find water staining around the rough opening, full-frame is the honest answer. On Timberwood Park homes with stone exteriors, full-frame lets us re-flash the opening correctly, which matters during July thunderstorms that dump an inch of rain in 30 minutes.
Trusted Brands We Service in Timberwood Park
We carry and install Therma-Tru doors, ViewLux picture windows, PGT impact-rated units, and CGI hurricane lines for Timberwood Park homes that want wind protection on exposed lots. Because we stock common local parts and order directly from these manufacturers, turnaround on a warranty claim or a replacement sash is faster than if we were routing through a distributor in another market. If you have an existing PGT or Therma-Tru product that’s failing, we service it too, not just replace it.

AfterCommon Window Installation Problems We See in Timberwood Park Homes
- Seal failure on west-facing windows. Homes off Borgfeld Road and Bulverde Road without shade trees get hammered by afternoon UV, which breaks down the sealant between panes and fogs the glass. Once argon gas escapes, the window loses most of its insulating value.
- Warped frames and failed sash locks on double-hungs. Timberwood Park’s temperature swings, especially in spring and fall, stress vinyl and wood frames. We see double-hung sashes that won’t stay up or locks that no longer line up because the frame has twisted.
- Water intrusion around stone veneer. Improper flashing on stone exteriors is a common original-construction flaw from the 1990s. During a Hill Country thunderstorm, water finds the gap and runs down behind the stone, staining drywall and rotting the rough opening.
- Septic and well setbacks complicating access. On acreage, the septic drain field and well head restrict where a lift or a dumpster can sit. We scope this before quoting so the county inspection passes the first time and the drain field stays intact.
Pricing for Window Installation in Timberwood Park, TX
Here are honest numbers for the Timberwood Park market. A standard vinyl retrofit on a double-hung runs $850 to $1,400 per opening. A wood-clad retrofit runs $1,200 to $2,000. Full-frame replacement with new interior trim runs $1,500 to $2,800 per window on a brick home, $1,800 to $3,200 on a stone veneer home because the exterior cut-back takes longer. Bay windows run $3,800 to $7,500. Impact-rated PGT or CGI units add $400 to $900 per opening depending on size and design pressure rating. The Bexar County permit fee is a separate line item, usually $150 to $400 depending on the number of windows. Every quote is in writing before we order anything, and the price does not change unless you change the scope.

FAQs About Window Installation in Timberwood Park
Yes. Most Timberwood Park homes sit on unincorporated Bexar County land, so window replacement that changes the rough opening or the structural header requires a Bexar County permit, not a City of San Antonio permit. A like-for-like retrofit with no structural change may not require one, but we verify this for every job and include the permit fee as a separate line item in your written quote. Call (325) 420-4173 and we’ll check your specific parcel before ordering anything.
On a Timberwood Park acreage lot, the septic drain field and well head create setback zones where we cannot stage a lift, park a dumpster, or drive heavy equipment. We mark these zones before quoting, plan the work path around them, and confirm with the county inspector that our staging complies with the recorded setback distances. This keeps your drain field intact and prevents a failed inspection that delays the job. It’s a simple step most window companies skip, and it saves you real money in rework.
Yes, and the biggest savings come on west-facing walls without shade trees. A PGT or CGI impact window with a SHGC of 0.25 or lower blocks most of the solar heat that currently bakes through older clear glass, which can cut afternoon cooling load in that room by a measurable amount. The window itself doesn’t change your AC unit’s efficiency, but it reduces how hard the system has to work from 3 to 7 p.m. in July and August. For a full picture of payback, we’ll quote the glass package you actually need, not a generic upgrade.
Many insurers in Bexar County offer a premium discount for impact-rated windows and doors, especially on open lots with full wind exposure like much of Timberwood Park. We provide the product certification documents you need to submit to your agent. The discount varies by carrier and policy, so we tell clients to call their agent with the specific model numbers before we order. We don’t promise a dollar figure we can’t verify, but we do provide the paperwork your agent will ask for.
Yes. On a stone veneer or brick Timberwood Park home, a properly done retrofit leaves the exterior veneer and interior trim untouched, replacing only the sash and frame inside the existing opening. If the original frame is square and dry, the exterior stays exactly as it is. If we find water damage or a warped frame when we pull the old unit, we’ll stop and show you before we do anything else, then give you a written price for the full-frame work. No surprises, no change order unless you approve it first.
