Window Company in Nassau Bay, TX
Westlight Windows & Doors is the window company Nassau Bay homeowners call when single-pane aluminum frames have corroded past saving and sliding patio doors no longer close square. Most of the homes here went up between the 1960s and early 1980s, and the humid Gulf air has been working on those original windows ever since. If you’re seeing condensation between panes, hearing wind whistle through the seals, or fighting a patio door that sticks, we’ll give you a written price before any work starts. Call (325) 326-4211 for a free estimate.
Why Nassau Bay Homes Are Different
Nassau Bay sits on a peninsula between Clear Lake and Galveston Bay, which means two things for windows and doors: salt-laden humidity and hurricane wind loads. The 1960s and 1970s patio homes clustered near the water were built with single-pane aluminum frames, and after 40 to 60 years of Gulf moisture, those frames corrode at the corners and the hardware seizes. We regularly see aluminum sills that have pitted through entirely, especially on the bay-facing elevations.
The other Nassau Bay signature is slab movement. Most homes here sit on slab foundations over expansive clay, and in the older sections near the water, sliding glass doors settle out of square. A door that scraped the track ten years ago may now refuse to latch at all. Any new window or door on those openings has to start with re-alignment, or the new unit inherits the old problem. Brick veneer over wood frame is the standard construction, so rough openings are often smaller than modern unit sizes and need careful reframing rather than a quick swap.
Our Main Nassau Bay Services
The two calls we get most in Nassau Bay are for window replacement on aging aluminum frames and door installation where sliders have failed. Each job gets its own page with local pricing detail and the conditions that drive cost here.
Window Replacement in Nassau Bay
Window replacement in Nassau Bay usually means pulling corroded single-pane aluminum and putting in something that handles the coastal humidity. Impact-rated glass is the most common upgrade because so many homes sit inside the hurricane wind zone. We measure every opening, account for brick veneer tolerances, and write a fixed price before ordering anything. See the full local breakdown at Window Replacement in Nassau Bay.
Window Installation in Nassau Bay
New construction and addition work in Nassau Bay brings window installation into the frame before the drywall goes up. The site conditions change the game: slab-on-grade layout means rough openings need to be shimmed precisely, and the proximity to Galveston Bay means flashing details have to shed water aggressively. We work from the builder’s spec sheet or from architect drawings. Full detail is on Window Installation in Nassau Bay.
Door Installation in Nassau Bay
Door installation in Nassau Bay frequently involves replacing sliding patio doors that face the lake or bay and have been fighting salt air for decades. The frame is often out of square from slab settling, so the first step is getting the opening true before the new door goes in. We install Therma-Tru entry doors and heavy-glass sliders built for coastal exposure. Read the full local guide at Door Installation in Nassau Bay.
