AfterFast, Reliable Door Installation Across Houston
Door installation in Houston runs $1,200-$4,800 for a standard entry door replacement, and $3,500-$9,500 when the opening needs an impact-rated unit that meets TWIA wind-load standards. Most Houston jobs take one day once materials arrive, though clay-soil slab movement and TWIA documentation add steps that generic installers skip. Sightline Windows & Doors serves every Houston neighborhood with written pricing before work starts, a measured survey you keep, and a documented photo record when the job is done. Call (509) 265-6387 to schedule your free estimate.
Why Sightline Windows & Doors Is Houston’s Preferred Door Installation Company
Houston homeowners research contractors harder than buyers almost anywhere else in Texas, because one bad installation here can void wind-loss coverage, bind a door by August, or fail inspection outright. Our Houston crews work on Meyerland ranches, Westbury tract homes, Spring Branch remodels, and Clear Lake older builds every week. We know which frames have shifted because of Beaumont clay, which original aluminum thresholds have corroded from 75% year-round humidity, and which TWIA paperwork matters when the claim gets filed.
Sonia Raman leads our Houston operation, and every quote that leaves our office carries the Haven Standard in writing: a measured survey you keep, a fixed price before any tool is lifted, a background-checked crew identified by license number, and a photo record delivered when the job closes. That is the same document set on the job board for 18,000+ openings we have installed since 2012. No verbal assurances. No change orders after the fact. The measurement and the quote are the same document, because they have to be.

Our Door Installation Services in Houston
Entry Doors
A functional entry door in Houston does more than open and close. It has to seal against Gulf Coast humidity, stay square when the slab beneath it shifts, and hold paint or finish through UV that destroys cheap factory coatings in three or four years. We install Therma-Tru and PGT entry doors in Houston daily, shimmed to allow for the seasonal movement Beaumont clay forces on every pier-and-beam and slab foundation in the metro. Your written quote includes the measured rough opening, the shim plan, and the fasteners, not just a door price.
Hurricane-Proof Front & Entry Doors
In Harris County, this is not an upgrade option. It is the difference between wind-loss coverage that holds and a policy that will not pay. TWIA catastrophe-area designation means impact-rated glazing, large-missile ratings, and laminated interlayers are required on protected openings for the homeowner’s coverage to survive a claim. We specify PGT and CGI impact-rated entry doors in Houston based on the exposure the opening actually faces, then we document the installation with photos and product data sheets so the paper trail matches the policy requirement. That documentation is standard on every Houston impact door we install, not an add-on.
French & Double Doors
Houston’s humidity attacks double door systems harder than any other opening. The meeting stile, the astragal, the threshold, the hinges: every component has to be selected for a subtropical climate or the doors will swell, bind, and leak within two seasons. We install French and double doors in Houston with sill pans, compression astragals, and jamb shimming that accounts for slab movement across the full width of the opening, which is where most failures start. CWS and ES Windows service in Houston give us the performance tiers to match the opening without overpaying for rating you do not need.
Replacement Doors
Replacing a door in Houston usually means replacing a frame too. The 1960s and 1980s tract homes that dominate Meyerland, Westbury, and the Clear Lake corridor were built with aluminum thresholds and jambs that have spent decades oxidizing in a salt-tinged, high-humidity environment. We pull the old frame, measure what the slab has done to the rough opening, and set the new unit to close correctly even after the next drought cycle. Your written quote covers the frame, the shims, the sealant, and the trim, because separating those invites a change order.
Storm & Exterior Doors
A storm door in Houston has to do two jobs at once: manage airflow during the nine humid months and hold up to wind gusts that regular exterior doors never see. We install storm and exterior doors in Houston with PGT and CWS product lines, sealed against driving rain and flashed to drain water away from the sill, because Houston storms do not give warning. The installation includes a photo record of the flashing and sealant before the trim goes on, so you can see what was done behind the casing.

BeforeAfterTrusted Brands We Service in Houston
We install eight manufacturer lines, but in Houston we specify PGT, CGI, and CWS most often because those three carry the TWIA-approved product data sheets and large-missile ratings that Harris County homeowners need for wind-loss coverage. Each line is selected by performance tier and price range, not by what we have in stock. That means a $1,200 entry door in Meyerland gets the same written-quote treatment as a $9,000 impact-rated PGT unit near the Bay. Parts and service calls are coordinated from our Houston office, and we stock common replacement components locally so warranty work does not sit waiting on a freight delivery from Florida.
Common Door Installation Problems We See in Houston Homes
- Doors that bind after one drought cycle. In Meyerland and Westbury, the Beaumont clay under the slab shrinks every summer and swells every rainy season. A jamb shimmed tight to the current rough opening will bind by August and gap by October. We shim for the movement, not for the measurement.
- Standard non-impact doors in a TWIA catastrophe zone. Homeowners install a perfectly good standard door, then discover on the next windstorm claim that the opening no longer meets TWIA product documentation standards. The door works fine. The insurance does not.
- Rot in the sill and jamb bottom from hidden water entry. Houston’s humidity means every exterior door needs a properly flashed sill pan and backdam. Most original 1960s-1980s installations have neither, and the damage is invisible until the threshold collapses.
- No documentation trail. The door was replaced, the invoice is somewhere, but there is no photo record of the flashing, the shims, or the product label. When the claim examiner asks for proof that the opening is TWIA-compliant, the homeowner has nothing to send. We deliver the evidence with every job.

FAQs - Door Installation in Houston
A Houston entry door in a TWIA catastrophe area must meet the wind-load rating specified for your structure’s design wind speed, and protected openings require impact-rated glazing with large-missile ratings and laminated interlayers. The exact design pressure depends on your home’s location, exposure category, and roof height. What matters is that the product data sheet and the installation documentation match the rating, because the claim examiner will ask for both. Call (509) 265-6387 and we will spec the opening correctly before you buy anything.
Yes. Houston requires a permit for exterior door replacement when the opening is altered or when the work is part of a windstorm-compliant installation. The inspection creates the public record that ties your door to the TWIA-approved product documentation. A compliant Houston quote includes the permit line item, the inspection scheduling, and the photo record of the flashing and shims before final trim. A cheap quote leaves all of that out, and you find out at claim time.
The Beaumont clay under those neighborhoods shrinks during summer drought and swells when the rains return, and a slab can move enough to rack a door frame measurably out of square within one season. If the installer shimmed the jamb tight to the current rough opening, the door will bind by August or gap by October. The fix is to shim for the movement, not the measurement, and to use fasteners that allow minor seasonal adjustment. In a Meyerland ranch, our crew replaced a bowed Therma-Tru entry door with a PGT impact-rated unit this way, and the door still closes plumb after August drought.
In many Houston homes, yes. Texas insurance carriers offer premium credits for documented windstorm mitigation features, including impact-rated doors with large-missile ratings and TWIA-compliant installation. The credit requires the product data sheet, the permit record, and the installation documentation. If those documents are missing, the door still protects the house, but the premium does not move. That is why our Houston installs include the full document set as standard. Call (509) 265-6387 for a free estimate and we will tell you exactly what your opening needs to qualify.
A compliant Houston quote includes the TWIA-approved product specification with large-missile rating, the permit line item, the inspection scheduling, the shimming plan for seasonal slab movement, the flashing and sill pan details, and the photo record delivered when the job closes. A cheap quote includes a door and a labor number. The difference shows up when the frame binds a year later or the windstorm claim gets denied because the opening cannot produce the right paper. We price the work in writing before anything starts, and that written number is the final invoice. Call (509) 265-6387 to schedule your free measured survey.
