Fast, Reliable Door Installation Across Friendswood
Door installation in Friendswood usually means one of two things: replacing a worn-out entry door on an older brick ranch, or upgrading to an impact-rated unit that will pass the city’s windborne debris inspection. Most exterior door replacements in Friendswood run $1,800 to $4,600 installed, depending on the product line and whether the frame needs full replacement. We’ve been replacing doors in Friendswood since 2009, and we know exactly what the city inspectors look for before they’ll sign off. If you’re pricing out a new front door, a storm door, or a replacement slider, call us at (325) 326-4211 and we’ll walk you through what it actually costs.

Our crews work in Friendswood every week, from the older sections near FM 528 down to the newer stucco developments off Blackhawk Boulevard. We schedule a firm arrival window, show up when we said we would, and leave the job site cleaner than we found it. That’s the Kingswell Way, and it’s been our standard since Owen Satterfield started this company in 2009.
Why Westlight Windows Houston Is Friendswood’s Preferred Door Installation Company
We carry eight manufacturer lines, including Therma-Tru, PGT, CGI, CWS, and ECO Window Systems, so when a Friendswood homeowner asks about a Therma-Tru fiberglass entry door, we’re not trying to talk them into something else we happen to stock. We order the right product for the house and the wind-load zone.
Friendswood is different from most of the Houston suburbs around it. The city enforces the 2018 IRC with Texas amendments, and that means exterior door assemblies have to show Florida Product Approval, Miami-Dade NOA, or TDI listing for a large-missile impact rating. A contractor who mostly works in Pasadena or Deer Park may never have pulled a permit under that standard. We have, many times.
Every job gets a written price before any work starts. Not an estimate range, not a “we’ll see once we open the wall” figure. A written number, handed to you before a single screw turns. If something fails during the guarantee period, we come back and fix it at no charge. That’s the 365-Day Done Right Promise, and it’s handed to every customer at job completion in writing.
Our technicians are background-checked and uniformed, so you know exactly who’s walking through your door. And when you call our office at (325) 326-4211, a live person answers, 24 hours a day, seven days a week. Not a voicemail box.
Door Repair in Friendswood
Door repair in Friendswood often comes down to two things we see constantly: roller tracks on older sliding glass doors that have corroded from repeated exposure to afternoon thunderstorms, and wood rot hidden under the threshold of exterior doors, especially in the Forest Bend area. How much does it cost? A simple roller track replacement or threshold repair typically runs $220 to $450 in Friendswood, while repairing a door that needs new framing or flashing work can reach $900 to $1,500. If the damage is severe enough that the slab itself is compromised, a full replacement usually makes more financial sense than limping along with repeated repairs.
We start every repair with a real inspection of the underlying structure. A door that sticks or drags after a Friendswood storm usually isn’t just dirty rollers. It’s often a threshold that’s been absorbing wind-driven rain for years, and the framing underneath has started to go soft.
Threshold and Frame Repair
When water gets past a failed threshold seal, it sits in the framing and rots it from the inside. We pull the old threshold, cut out the rotted sections of jamb and sub-floor, and replace them with pressure-treated lumber or composite material that won’t hold moisture. The new threshold gets a continuous sill membrane flashed up the jambs, which is the detail most low-cost installers skip, and it’s exactly the detail that fails in a Friendswood wind-driven rain.
Sliding Door Track Replacement
Friendswood’s afternoon thunderstorms push water horizontally, not just down. Over time, that water gets into the roller track of rear sliders and corrodes the bearings. Homeowners notice the door getting harder to move, then one day it won’t budge. We replace the rollers and the track as a set, and we check for water intrusion at the weep holes while we’re in there. The repair usually takes a single visit.
Exterior Door Installation in Friendswood
Exterior door installation in Friendswood means installing a door that will pass a windborne debris inspection, not just a door that looks right. Most front entry door replacements in Friendswood run $1,800 to $3,800 installed for a standard single door, and French or double door installations typically run $3,200 to $5,600, depending on size, glass package, and impact rating. If you’re replacing a rear sliding door with an impact-rated unit, expect $2,900 to $4,800. These are installed prices, including the permit-grade documentation the city requires.
We always pull the permit. Some contractors will offer to skip it to save a couple hundred dollars, but in Friendswood that means no final inspection, no wind mitigation credit, and a door that may not be covered if a storm blows it in.
Impact-Rated Front Entry Doors
Friendswood sits inside Texas’s windborne debris region, and the city enforces a large-missile impact rating on exterior door assemblies. What that means in plain English: the door and its glass have to withstand a 2×4 fired at it at 34 miles per hour without the glazing breaking through. Therma-Tru, PGT, and CGI all produce doors that carry Florida Product Approval or Miami-Dade NOA for this standard, and we install them with the fasteners spaced to the manufacturer’s engineering letter.

This is where a generic quote falls apart. A cheap installer will sell you an impact-rated slab but leave out the sealed engineering documentation that ties that specific door to Friendswood’s wind-load map. Without that letter, the city won’t close the permit, and you can’t file the wind mitigation credit under Texas Insurance Code §2210.
French and Double Door Replacement
Double doors are more demanding than single doors, because the meeting stile in the center has to carry the same design pressure as a solid wall. In Friendswood, that means the active leaf and the fixed leaf both need to be anchored per the manufacturer’s approved installation method, and the astragal between them has to interlock tightly enough to keep wind-driven rain out. We install French doors with continuous head and sill flashing, and we set the threshold on a bed of sealant so water never finds a gap.
Trusted Brands We Service in Friendswood
We’re factory-authorized to install products from eight manufacturers, and we keep our Friendswood work centered on the lines that carry the wind-load documentation the city requires. For entry doors, that’s usually Therma-Tru fiberglass or PGT impact-rated units. For sliding glass doors, CWS and ECO Window Systems both produce large-missile-rated units with laminated glass. We also service existing doors from ES Windows and Mr-Glass that may have been installed by a previous contractor. Because we order directly from these manufacturers, we can get replacement parts like astragals, thresholds, and weep covers to our Friendswood customers faster than a general contractor who’s ordering through a supply house middleman.
Common Door Installation Problems We See in Friendswood Homes
- Failed roller tracks on original rear sliders. Homes built in the 1970s and 1980s, especially ranch-style brick veneer homes off FM 2351 and in Forest Bend, often have original aluminum sliding doors. After decades of afternoon thunderstorms, the roller bearings corrode and the track warps. The door binds, then stops moving entirely.
- Wood rot concealed under entry door thresholds. Hollow-core exterior doors on older Friendswood homes let water in at the threshold seam. We regularly find the jamb and sub-floor rotted out underneath a door that still looks presentable from the outside. If the new slab is anchored to that compromised framing, it won’t pass the city’s screw-spacing check for HVHZ opening protection.
- Non-impact doors in windborne debris zones. Many Friendswood homes still have front doors with ordinary annealed glass. A door without a large-missile impact rating won’t pass the city’s permit inspection for replacement work, and if a storm breaks that glass, the pressure change can lift the roof. This is a real failure mode in a hurricane-prone suburb.
- Improper flashing on 2000s stucco homes. The newer stucco developments in west Friendswood present a different challenge: the door opening is set into a foam and stucco assembly, and if the jamb flashing isn’t integrated with the drainage plane, water gets behind the stucco and causes long-term damage. We’ve seen this on homes off Blackhawk Boulevard where a previous door was caulked but never properly flashed.
Pricing for Door Installation in Friendswood, TX
Here are real numbers for Friendswood’s market, installed and including the permitting documentation:
| Door Type | Typical Friendswood Installed Price |
|---|---|
| Single entry door, non-impact, standard size | $1,800 – $2,800 |
| Single entry door, impact-rated (large-missile) | $2,600 – $3,800 |
| French or double door, impact-rated | $3,200 – $5,600 |
| Rear sliding door, impact-rated | $2,900 – $4,800 |
| Door repair (rollers, threshold, hardware) | $220 – $450 typical |
What moves the price: the size of the opening, whether the existing frame can be reused or needs full replacement, the brand and glass package you choose, and whether the job is a front door, a double door, or a slider with sidelites. A PGT or CGI impact door costs more than a non-impact door because the laminated glass and reinforced frame are more expensive materials, and the permitting documentation adds time. You’ll get a written quote before any work starts, and that number is the number. We don’t revise invoices at the door.

FAQs About Door Installation in Friendswood
A new front door in Friendswood needs a large-missile impact rating, documented by a Florida Product Approval, Miami-Dade NOA, or TDI listing for the specific door assembly installed. The city enforces the 2018 IRC with Texas amendments, and its windborne debris region designation means the inspector will ask for that documentation before closing the permit. If you’re replacing an entry door, expect the permit package to include the manufacturer’s NOA and a design pressure calculation that ties the door to Friendswood’s wind-load map. A door without that paperwork won’t pass. Call (325) 326-4211 and we’ll explain exactly which products meet the standard for your opening.
Yes, but only if the installation is documented properly. Texas Insurance Code §2210 allows Texas Windstorm Insurance Association policyholders to reduce their premium when the home has windstorm-compliant opening protection, and many private carriers offer similar credits. The key is the sealed engineering letter that matches the door’s Florida Product Approval or Miami-Dade NOA to the Friendswood wind-load map. A generic quote usually omits that letter because it takes time and costs money to produce. Our quotes include it, because without it, you cannot file the wind mitigation credit.
Friendswood’s afternoon thunderstorms push rain horizontally, and years of that wind-driven water corrodes the steel roller bearings inside the door’s track. The bearings seize, the rollers flatten, and the door starts dragging, then won’t move at all. It’s the single most common door failure we see in 1970s and 1980s ranch homes in Friendswood, and the fix is usually a new roller and track set rather than a whole new door. If the frame is still square and the glazing is intact, you’re looking at a repair under $450. If water has been getting past the track into the framing, the cost rises.
Yes. Brick veneer homes near Forest Bend typically have a 2×4 or 2×6 wood buck behind the door frame, which gives us solid anchoring for the fasteners the wind-load spec requires. Newer stucco homes in west Friendswood have a foam-insulated stucco assembly over the framing, and the door’s jamb flashing has to tie into the drainage plane behind the stucco. If it doesn’t, water from a wind-driven rain travels behind the stucco and you won’t see the damage for years. The anchoring and flashing details are different, and we handle both types regularly.
A Florida Product Approval, or a Miami-Dade NOA, is the document the Friendswood inspector looks for when closing out a door permit, because the city accepts those listings as proof of large-missile impact compliance. The inspector will check that the installed door matches the listing, that the fasteners match the spacing on the manufacturer’s installation instructions, and that the engineering letter ties the assembly to the local wind-load map. When we install a CGI or Therma-Tru unit in Friendswood, the NOA and design pressure documentation goes into the permit package before the inspection, so the inspection closes on the first visit.
If you’re ready to replace a door in Friendswood, or you just want to know what your project will cost, call Westlight Windows Houston at (325) 326-4211. We’ll give you a written price before any work starts, and we’ll stand behind the work after it’s done. That’s how we’ve done it since 2009.
