What makes Katy different is what’s behind the walls. Homes built in the 1990s and 2000s sat through decades of Gulf Coast humidity and two major code changes. When we pull an old door, we’re never sure what we’ll find until the casing comes off. That’s why we inspect the rough opening first and put every possible repair in writing before the first screw comes out.

Why Lightwell Windows Houston Is Katy’s Preferred Door Installation Company

We’re part of the Cedarwell network, operating under the Cedarwell Care Promise since 2010. Keith Yamada leads our door installation team, and he’s the person who checks in on jobs around Katy to make sure the C.A.R.E. values actually happened: 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. Those aren’t wall posters. They’re how our crews work when there’s a toddler napping in the next room or a dog watching from the hallway.

Katy homeowners keep calling us back because our written price stays the written price. No add-on at the end of the day unless you approved it first, in writing, with the new number in front of you. We also show up in uniform, background-checked, with shoe covers on before we step inside. When the job is done, we photograph the cleanup and send it to you before the crew pulls away.

Our Door Installation team carries eight manufacturer brands, but for Katy’s climate we most often recommend Therma-Tru for entry doors and ES Windows or Mr-Glass for sliding glass and specialty openings. The recommendation fits the home, not a vendor preference. If a door doesn’t need impact-rated glass, we won’t sell you impact-rated glass. If it does, we’ll explain exactly why and what the wind load numbers mean for your street.

Storm Door Installation in Katy

Storm Door Installation in Katy usually means adding a second, lighter door outside the main entry to block wind, dust, and summer heat from hitting the primary door directly, or replacing an old storm door whose frame has bent over years of 100°+ days. A quality storm door installed on a standard opening typically runs $300 – $900 in Katy, depending on glass type, frame material, and whether the existing frame needs shimming or replacement. Many homes in Grand Lakes and Cinco Ranch have original storm doors from the early 2000s with aluminum corners that are now pulling apart.

What We Inspect Before Installing

Before we hang a storm door on a Katy home, we check the main door’s threshold, the brick veneer around the opening, and the condition of the jamb. Brick veneer absorbs moisture from humidity and sprinkler overspray, and over time that moisture wicks into the wood behind it. If the jamb is soft, a storm door won’t fix the problem and we’ll tell you before we quote.

Pet and Child Safety on Storm Doors

Katy households with kids and dogs often want a storm door that can stay closed without latching hard enough to pinch fingers or trap a paw. We set closers to the slowest safe speed, check the latch tension, and use pet-safe sealants where options exist. The crew keeps tools quiet when they can, and we’ll ask before we move a stroller or a bike out of the way.

Sliding Glass Door Installation in Katy

Sliding Glass Door Installation in Katy usually means pulling a 1990s or early-2000s aluminum slider that has warped, fogged, or started leaking, and replacing it with a new unit that meets current wind load requirements. A standard 6-foot slider replacement in Katy typically runs $1,200 – $3,400, with impact-rated glass at the upper end. That price includes removal, disposal, frame repair if the opening is square, and new weatherstripping.

The Framing Problem Behind Old Sliders

On a Firethorne stucco home, our crew pulled an original 2005 aluminum sliding glass door that had warped so badly the jamb bowed outward. We found the rough opening never flashed correctly and the sill rotted, so we reframed it, wrapped the opening in peel-and-stick flashing, and installed a Therma-Tru sliding door with impact-rated glazing. All of that happened before the county inspector arrived. When we quote a slider in Katy, we plan for what the pull-out might reveal, because older master-planned homes are consistently under-flashed behind the brick.

What the Glass Type Actually Means

Katy sits in a hurricane-risk zone, and homes built after Harvey often need large-missile rated glass to satisfy wind mitigation inspections. Original 1990s sliders with annealed glass fail those checks and can cost homeowners their insurance discount. We’ll tell you if your existing panel qualifies or not, and what the replacement needs to meet for your specific subdivision’s code requirements.

Trusted Brands We Service in Katy

Lightwell carries eight manufacturer brands: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. For Katy doors, we typically install Therma-Tru for entry and storm door applications, ES Windows for high-efficiency sliders, and Mr-Glass for custom glass replacement on existing door panels. Because we stock common replacement parts for these brands locally, a Katy homeowner with a failed latch or a slipped roller on a Therma-Tru product isn’t waiting three weeks for a part to come from out of state.

Common Door Installation Problems We See in Katy Homes

• Rotted subfloors hidden under the threshold. Failed door frame waterproofing behind brick veneer lets Gulf Coast humidity wick through gaps, rotting the subfloor around the door before it’s visible. By the time the floor feels soft, the repair involves opening the wall, not just the door.
• Annealed glass sliders that fail wind mitigation. Original 1990s sliding glass doors with annealed glass and no large-missile rating fail post-Harvey wind mitigation checks, which kills insurance discounts. Homeowners discover this during an inspection, not because the glass broke.
• Vinyl service doors twisting in the heat. Low-quality vinyl service doors installed in 2000s-era Mason Road homes develop latch misalignment and air leaks as the frames twist under repeated 100°+ summer heat. The door looks fine but won’t latch in July.
• Fog between glass panes on 15 – 20-year-old doors. Along the Mason Road corridor, many 2000s-era homes are hitting the 20-year mark where failed seals are so common that a foggy glass panel is practically a rite of passage for new residents. The fix is a new insulated glass unit, not a repair.
