Houston, Texas — Replacement Windows & Doors
Window and Door Installation in Houston
HTX Construction installs replacement windows and doors throughout Greater Houston — selected for Houston’s climate, flashed and sealed correctly, and finished inside and out.
Replacement Windows
We replace single windows or the whole house, sizing each opening correctly and planning the interior trim so the new windows look built-in rather than set-in. Frame condition is inspected during removal, and any rot or damage found is repaired before the new unit goes in.
Glass options are chosen for the Houston climate — low-emissivity coatings, insulated glazing, and tinting or coatings where western exposure makes rooms uncomfortable. Actual energy outcomes depend on the home, and we discuss realistic expectations rather than promising savings figures.
Exterior, Entry, and Patio Doors
An entry door is the handshake of the house. We install exterior doors that seal against Houston’s wind-driven rain, with correct flashing, sweeps, and threshold detailing — and hardware, glass, and finish chosen to match the home’s architecture.
Patio and sliding doors get particular attention to the opening: track level, drainage, and interior floor transitions, so the door glides and drains the way it was designed to.

Interior Doors
Replacing interior doors is one of the highest-impact refreshes available: consistent heights, aligned casings, and matching hardware change how an entire house reads. We hang doors that swing true, latch cleanly, and line up across hallways.
Houston Heat, Humidity, and Storms
Houston windows and doors face three enemies: sustained heat and UV, moisture-laden air, and storm-driven rain. Products and installation details are chosen for all three — sealants rated for high temperatures, flashing layered to shed water, and finishes that hold up to Gulf Coast sun.
We do not represent any window or door product as hurricane-proof, and we do not promise energy-bill savings. What we do is install weather-appropriate products to manufacturer specifications with water management detailed correctly.
Flashing and Water Management
Most window and door failures are water failures, and they happen behind the finish. Installation follows a layered flashing approach — sill protection first, then the unit, then sealed weather barriers — so that water that gets past the face of the wall still drains out.
Rough openings are inspected and corrected before installation. A window installed in a compromised opening will leak no matter how well it is made.
Trim Repair and Finishing
Removing an old window or door often reveals trim, siding, or sheathing that needs repair. That work belongs in the same scope — exterior trim rebuilt and caulked, interior casing matched to the home’s trim profiles, and paint finished to blend with existing walls.
The goal is an installation where nothing looks new but the product itself.
Signs Replacement May Be Needed
Some failures are obvious: fog between glass panes, rot at the sill, locks that no longer engage, or a door that will not close in summer humidity. Others are quieter — paint peeling around a frame, floors darkening below a window, or rooms that never feel comfortable.
- Condensation or fog permanently trapped between panes
- Difficulty opening, closing, or locking windows and doors
- Soft or discolored wood at sills and frames
- Drafts and outside noise noticeably worse than in other rooms
- Water staining on walls or floors near an opening
Windows and doors are your home’s weather armor and its best light. Let’s replace them right.
Frequently Asked Questions
Can you replace just a few windows instead of the whole house?
Yes. We replace individual failed units or match new windows to existing ones when a full replacement is not needed. Whole-house replacement is recommended when units share a room and mismatched glass would be visible.
Do you repair damage found during installation?
Yes — rot, damaged sheathing, or bad flashing discovered during removal is repaired as part of the installation scope, with anything beyond the expected scope discussed with you before proceeding.
Are your windows hurricane-proof?
No product installed in an existing wall can honestly be called hurricane-proof, and we do not make that claim. We install weather-appropriate products per manufacturer specifications, with flashing and water management detailed for the Gulf Coast climate.
Will new windows lower my energy bill?
Better glazing and tighter sealing generally improve comfort, but actual savings depend on the home, the HVAC system, and usage. We do not promise specific energy savings.
How long does a window or door installation take?
Individual units are typically one-day installations; whole-house projects run longer and depend on unit count and any repair work found. We outline the schedule for your specific project during planning.
Which areas do you serve?
We install windows and doors throughout Greater Houston, including Houston, Pearland, Friendswood, League City, Clear Lake, Sugar Land, Missouri City, Manvel, and Alvin.
