Fast, Reliable Window Replacement Across Four Corners
Replacing windows in Four Corners means dealing with two forces that work against each other: sun that bakes aluminum frames all summer, and clay soil under the slab that shifts enough each dry season to rack jambs out of square. Most replacement jobs here run $600 – $1,800 per window installed, depending on whether you need a full-frame retrofit or a simpler sash swap. We’ve worked on homes off West Bellfort and along the new builds near the Beltway, so we know what this soil does to a window opening. Call (325) 326-4211 and we’ll give you a written price before any work starts.

Why Westlight Windows Houston Is Four Corners’s Preferred Window Replacement Company
We’re an independently owned and operated Kingswell location, and Owen Satterfield runs our crews with one rule: say the price before the work, show up in the window we gave, and put the guarantee on paper. Four Corners homeowners have told us what happened with the last guy: the quote went up at the door, or the crew never came back when the window fogged. That doesn’t happen here. Every job gets the Kingswell Guarantee, which means the written price you get before work begins is the price on the final invoice. If the repair fails inside the guarantee period, we return and fix it at no charge. We also answer the phone 24/7 with a live person, not a voicemail tree. Background-checked, uniformed technicians show up when we said they would, and they leave the site cleaner than they found it.
Our Window Replacement team stocks parts locally for Four Corners jobs, which cuts turnaround time when you need a sash or sealed unit ordered. We carry eight manufacturer lines, including PGT, CGI, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux, so the product matches the house instead of the other way around. That matters in a place where one street can have 1978 slab-on-grade tract homes and, two blocks over, a 2015 HOA community with wind-mitigation rules.
Window Glass Replacement in Four Corners
Window Glass Replacement in Four Corners usually means swapping a failed insulated glass unit (IGU) or a cracked pane, not pulling the whole frame. Most homeowners here call us for fogged glass, which happens when the seal between the two panes lets go. Four Corners’s humidity accelerates that failure: water vapor sneaks into the airspace, condenses on the glass, and you get that permanent haze. A standard IGU replacement in a vinyl or aluminum frame runs $250 – $700 per window depending on size and whether the glass is low-e (a thin coating that reflects heat back into the room in winter and out in summer). Impact-rated replacement glass, which some Four Corners HOAs require, runs higher, $500 – $1,100 per unit.
Seal Failure and Fogging
Most fogged windows in Four Corners are original single-pane or early double-pane units from the 1980s and 1990s. Once the seal fails, the glass isn’t doing its job anymore: you’re paying to cool air that leaks right through. We order the replacement unit to the exact measurements of your sash, not an off-the-shelf size.
Impact-Rated Glass Upgrades
If you live in a newer section of Four Corners where the HOA enforces wind-mitigation standards, you may need impact-rated glass even on rear windows. We’ll check your specific community rules and quote the right product, often PGT or CGI, without pushing you into a full-frame job you don’t need.
Window Sash Replacement in Four Corners
Window Sash Replacement in Four Corners is the fix for a window that won’t stay open, won’t seal, or has rot in the moving panel itself. The sash is the part of the window that holds the glass and slides up, down, or sideways. Four Corners’s clay soil heaves and settles, which racks frames just enough that a sash that worked in June binds by September. A sash replacement runs $350 – $900 per window for most vinyl or wood styles, including the new balances and weatherstripping. It’s faster than a full-frame job and usually takes our crew under two hours per opening.
Warped or Racked Sashes
We’ve seen jambs in Four Corners racked half an inch out of square from clay-swell movement. When that happens, the sash fights the track every time you open it. Before we order a new sash, we check the jamb with a level and shim it back to plumb where possible. That’s the difference between a fix that lasts and one that binds again next dry season.
Rotted Wood Sashes
Homes in the older sections of Four Corners, particularly those with original wood windows, get rot at the bottom rail of the lower sash. Heavy rain events soak that rail, and if the weep holes are clogged, water sits there. We replace the sash with a rot-resistant extruded vinyl or composite unit and make sure the weep system drains before we leave.

Trusted Brands We Service in Four Corners
We install and stand behind windows from ES Windows, ECO Window Systems, and Therma-Tru, among the eight lines we carry. Because we order from local distributors and keep common glass sizes and hardware in stock for Four Corners jobs, a typical sash or IGU replacement turns around in days, not weeks. If you bought a home here with builder-grade aluminum frames and you’re tired of them sweating in the summer, we can show you what an ES Windows vinyl replacement or an ECO Window Systems insulated unit feels like in the same wall.
Common Window Replacement Problems We See in Four Corners Homes
- Builder-grade aluminum frames corroding at the weep holes. Homes built in the 1970s and 1980s across Four Corners often used the cheapest aluminum extrusions available. Your weep holes clog with corrosion, water tracks into the jamb, and the rough opening starts to rot during heavy rain. We catch it during replacement and treat the opening before installing the new frame.
- Sliding glass doors that bind after a dry summer. Clay soil under the slab heaves unevenly, throwing the fixed panel out of line with the track. We see this weekly in Four Corners, far more than in nearby Houston where soils run sandier. Sometimes the track can be planed and reset; other times the whole door needs a full-frame replacement to square it up.
- Non-tempered single-pane windows that fail wind-mitigation rules. Pre-1990 Four Corners homes often have plain annealed glass. Homeowners add impact film thinking it satisfies the HOA, but it doesn’t pass large-missile testing. You need impact-rated glazing in a proper frame, which we can quote before you spend money on a temporary fix.
- Sashes that won’t stay up in south-facing bedrooms. Years of afternoon sun and humidity degrade the balance springs or spiral balances. We replaced a set on a Briarwood cul-de-sac where the homeowner’s south-facing master bedroom sash kept dropping; the jamb had racked half an inch out of square from clay-swell movement, so we reinforced the shim points and installed a low-E insulated unit rated for high wind loads.

FAQs About Window Replacement in Four Corners
Four Corners’s slab-on-grade homes sit on expansive clay that can shift seasonally by over an inch, racking window jambs out of square more than Houston’s sandier soils do. Before any replacement, we level-check the jamb and shim it plumb, and we order custom-sized sashes when the opening is no longer square. That’s standard practice on our Four Corners jobs and the single biggest reason a window in this area fails early. Call (325) 326-4211 to schedule your free estimate.
Properly installed replacement windows won’t void a structural warranty, but cutting into load-bearing framing without a permit can. We pull permits on every Four Corners job that requires one, and we keep the structural members intact while replacing the window in the existing opening. If your builder warranty is still active, we’ll document the installation method so you have a record for any future claim. We’ll also match the product to your community’s specific wind-mitigation rules.
It varies by community. Some newer Four Corners developments require impact-rated glazing on every opening, while others only require it on street-facing elevations or windows within a certain distance of the property line. We check your community’s architectural guidelines before we quote, so you don’t buy glass the HOA will reject. Most of the time, impact-rated inserts add $400 – $800 per window over standard insulated glass.
Yes, in many cases. If the clay soil has shifted the frame slightly, we can sometimes plane the track or reset the rollers and realign the panel without touching your windows. If the frame itself has racked, or if the fixed panel is no longer plumb, a full-frame door replacement is the honest fix. We’ll tell you which one applies to your door before you spend a dollar, and you’ll get that recommendation in writing. Call (325) 326-4211 and we’ll come look.
To qualify for most wind mitigation discounts, the entire window assembly, frame included, must meet the current rating standards. Replacing just the sash usually isn’t enough because the frame’s design and mounting are part of the rating. If you’re in Four Corners and want the insurance discount, a full-frame impact-rated replacement is the better path. We’ll quote both options so you can see the price difference before deciding.
If you’re tired of windows that sweat, stick, or won’t stay open, call (325) 326-4211 today. We’ll schedule a free estimate, give you a written price before any work starts, and show up in the window we gave you. That’s how we’ve done it in Four Corners since day one.
