Call (254) 401-4583 and we’ll come out to measure, inspect your framing, and give you a written price before anything gets ordered.
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.
Styles & brands we work with








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.

AfterCommon 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.
Pricing for Door Installation in Katy, TX
Here’s what Katy homeowners should expect to pay, fully installed:
- Storm door: $300 – $900
- Standard entry door: $450 – $1,900
- Sliding glass door: $1,200 – $3,400 (higher for impact-rated)
- French or double doors: $1,800 – $4,200, depending on size and glass package
The biggest cost driver in Katy is what’s inside the wall once the old door comes off. Rotted framing, missing flashing, or a rough opening that needs reframing adds real money but should never be a surprise. We write allowances into your contract so you know what repairs cost before they happen. No change order gets signed without a new written price. Call (254) 401-4583 for a free estimate and a line-by-line quote before you decide anything.
One more thing worth knowing: many Katy homes in master-planned communities like Cinco Ranch and Firethorne sit in Fort Bend County, where a separate county permit inspection is required when a door installation alters the rough opening. We pull all permits and schedule those inspections as part of the job. Houston-based crews sometimes overlook the Fort Bend step until the job stalls. We don’t.

FAQs About Door Installation in Katy
Yes, any door installation in Katy that alters the rough opening requires a windstorm inspection through the county’s permit process, and if we open the wall and find framing damage, the scope expands to reframing, flashing, and resealing before the inspector ever arrives. We handle the permit and inspection scheduling as part of your written quote. Call (254) 401-4583 and we’ll walk you through exactly what your specific home needs.
The original 2004 Cinco Ranch front door warped because constant Gulf Coast humidity and intense sun exposure on the brick veneer cause the wood frame to swell and shift unevenly while the door slab dries at a different rate. Once the jamb moves, you get daylight at the strike side. A new pre-hung door with proper sealing usually solves it, and the price runs $450 – $1,900 depending on material. We’ll quote you a fixed number before we order anything.
In many Katy homes, yes, a hurricane-rated door can be installed into the existing opening as long as the framing is sound and the rough opening meets current wind load requirements. We’ll inspect first and tell you if the existing jamb can support an impact-rated unit. If it can’t, you’ll know the cost of adjusting it before work starts.
The fog between panes on a 2008 Grand Lakes back door is a failed insulated glass unit seal. Humidity gets inside the sealed space between the glass, condenses, and leaves mineral residue on the glass surface. The fix is a new IGU or a replacement door, which in Katy usually runs $1,200 – $3,400 for a slider with glass replacement. Call (254) 401-4583 and we’ll tell you which option makes sense for your door.
A storm door replacement that does not alter the rough opening usually does not need a permit in Fort Bend County, but if the existing frame is damaged and we need to reframe, it becomes a structural repair and requires a permit and inspection. We’ll determine that during the initial site visit and include any permit fees in your written estimate.
If you’re weighing options or tired of guessing, call (254) 401-4583. Keith Yamada and our team will come out to your Katy home, inspect the opening, and hand you a written price with every line item explained. No surprises, no pressure, just the number and a plan.
