Window Company in Houston, TX
Westlight Windows & Doors is the window company Houston homeowners call when they want a written price before work starts, a real arrival window, and a guarantee that’s actually on paper. Houston’s mix of century-old bungalows, sprawling 1980s suburban tracts, and hurricane-exposed coastal neighborhoods means no two window or door jobs look the same here. Heat, humidity, and storm cycles punish the wrong products fast. Call (325) 326-4211 to talk through what you’re seeing at your house and get a straight answer about what it’ll take to fix it.
Why Houston Homes Are Different
Houston has no citywide zoning code, and building standards shift block by block. In Clear Lake and other storm-rated pockets, that means impact-rated windows and proper flashing details are non-negotiable. Drive fifteen minutes to Sharpstown or Meyerland, and you’re looking at 1970s aluminum frames that were installed without flashing and have been leaking through decades of thunderstorms. A contractor who treats Houston as one uniform market is going to miss something important.
The housing stock spans everything: wood double-hungs in Heights bungalows that date to the 1920s, single-pane aluminum in 1980s and 1990s suburban builds, and newer construction where energy codes finally pushed builders toward low-e glass (a thin coating that reflects heat back into the room in winter and out in summer). Humidity is the quiet killer here. Seal failure, wood rot around sills, and warped frames show up early when moisture rides in on Houston’s subtropical air. We see it most after strong storms, when calls spike for water intrusion around windows in older Meyerland homes and other flood-prone neighborhoods.
The lesson is simple: the right window for a Heights bungalow is not the right window for a Clear Lake house, and the installation details matter as much as the glass. Owen Satterfield and the Westlight team spec every job to the house, not to a generic Houston average.
Our Main Houston Services
Here are the three services Houston homeowners call us about most, each with its own dedicated page explaining local conditions, product choices, and specific pricing.
Window Replacement in Houston
Replacing windows in Houston usually means pulling out failing aluminum or old wood units and putting in something built for heat, humidity, and storm season. We help you sort through impact-rated PGT and CGI, energy-efficient ECO Window Systems, and other options that actually make sense for your exposure. In neighborhoods like Sharpstown with unflashed 1970s frames, we’re often correcting someone else’s shortcut at the same time we’re putting in the new unit. Window Replacement in Houston covers full pricing, timelines, and what makes a Houston replacement different.
Window Installation in Houston
Window installation in Houston is about more than setting a frame true. It’s about flashing details that hold up through sideways rain, humidity that won’t let the rough opening dry out, and frames that swell and shift with the seasons. Whether you’ve bought windows yourself and need them set, or you’re working with us on a full selection and install, we treat every opening like it’s the one that’ll leak if we rush it. You can see the full scope on our Window Installation in Houston page.
Door Installation in Houston
Houston doors take a beating: heat on one side, air conditioning on the other, and humidity that can warp a slab that isn’t sealed correctly. We install Therma-Tru entry doors, which hold up to this climate far better than big-box pine slabs, and we set them so the threshold doesn’t start dragging in year two. A door that’s out of square after one summer is not a door problem, it’s an installation problem. Door Installation in Houston breaks down the process and pricing.

What moves a Houston price up: full-frame replacement when rot or failed flashing requires it, going from standard glass to impact-rated, and second-floor access that makes work slower. What doesn’t change: your written price. You’ll have it before any work starts, and it won’t get revised at the door.
Neighborhoods We Serve in Houston
Most Houston jobs fall within a 30 to 45 minute drive of our dispatch coordination office, depending on traffic and how the day’s schedule is running. Crews regularly work on both sides of the Loop and into the surrounding suburbs. Some of the neighborhoods where our window and door work shows up week in and week out:
- The Heights, where wood double-hungs and restoration-level care are the norm
- Clear Lake, pushed hard by hurricane exposure and salt air
- Sharpstown, with its leak-prone 1970s aluminum frames
- Meyerland, where repeated flooding means real scrutiny on flashing and seals
- Kingwood and Humble-adjacent areas, where 1980s and 1990s single-pane builds dominate

FAQs About Window Company in Houston
Most straight window replacements don’t require a city permit in Houston, but structural changes, new openings, and some door replacements can trigger requirements depending on jurisdiction. We check the rules for your specific address before work starts, and we handle the paperwork if a permit is needed.
In Houston’s climate, window seals in budget aluminum frames often fail within 10 to 15 years, and wood rot around sills can show up faster if flashing was never done right. Homes built since the 2000s with low-e glass generally fare better, but even good products fail early when installed without proper detailing.
Yes. From measuring and product selection through installation, cleanup, and the written guarantee, one Westlight crew runs the whole job. You won’t get a subcontracted crew you’ve never met. Call (325) 326-4211 for a free estimate and a written price before any work begins.
