Door Installation in Nassau Bay, TX: What It Costs and What the Code Actually Requires
Door installation in Nassau Bay runs $1,800 – $4,600 for a standard front entry door, $2,400 – $6,800 for an impact-rated front door with a Miami-Dade or TAS rating, and $3,200 – $9,500 for a sliding patio door replacement, depending on slab condition, jamb corrosion, and wind-load requirements. Most Nassau Bay homes date to the 1960s – 1980s, which means we’re rarely swapping a door cleanly. We’re usually re-squaring a slab-settled opening and replacing a corroded aluminum or steel jamb before the new door can meet the design pressure rating the city inspector will ask for. Call (325) 326-4211 before you pull a permit. We’ll tell you what your opening actually needs and what a compliant quote includes.
Key Takeaways:
- Nassau Bay enforces wind-borne debris zone requirements. Exterior doors facing the bay side or open water typically need a Large-Missile impact rating, not a basic wind-rated unit.
- The original 1960s – 1980s patio homes on slab foundations settle. A sliding door that sticks won’t pass inspection until the frame is re-squared.
- Galveston Bay humidity corrodes original aluminum jambs and thresholds. Installing an impact door into a rotted jamb voids the design pressure rating.
- Westlight Windows Houston gives you a written price before any work starts and a written guarantee when the job is done.
Why Westlight Windows Houston Is the Door Installation Team Nassau Bay Homeowners Call Back
We know this housing stock. Nassau Bay is mostly single-family detached patio homes built from the 1960s to the 1980s, brick veneer over wood frame on slab foundations. The original doors were single-pane aluminum sliders and steel or fiberglass entries, and four decades of Gulf moisture have not been kind to them. Our Door Installation crews have worked on San Sebastian Lane, along Upper Bay Road, and through the older sections near Swan Lagoon. We know what hides behind those original jambs.
Owen Satterfield runs our Nassau Bay projects personally when the job involves slab movement or wind-load documentation. That’s not a sales trick. It’s because those are the two failure points that cost homeowners money at inspection. Every crew member is background-checked and uniformed. Every quote is written, with the price fixed before any work begins. The phone line is answered by a live person 24/7, which matters when a door won’t close on a Friday evening and you need someone to walk you through it.
Westlight Windows Houston is an independently owned and operated Kingswell location, founded in 2009. We carry eight manufacturer lines, including PGT, CGI, and Therma-Tru. The Kingswell Guarantee puts four promises in writing on every job: the price before work starts, a committed arrival window, a clean job site, and a written guarantee on the completed work. If it fails, we come back at no charge. That’s the deal, and it’s printed on paper.
Front Door Replacement in Nassau Bay
Front door replacement in Nassau Bay typically runs $1,800 – $6,800, and the spread isn’t about trim options, though our Window Installation in Nassau Bay follows the same thorough assessment process. It’s about whether your opening is square, whether the jamb is rotted, and whether your home sits in a wind-borne debris zone that requires a Large-Missile-rated assembly. Most original front entries on 1970s patio homes were installed on slab foundations that have since moved a quarter-inch or more. The door still opens fine, but the frame is out of square enough that a new pre-hung assembly won’t sit flush without shimming and re-anchoring.
Impact-Rated Front Entries
If your home’s front door faces Galveston Bay or any open water corridor, the city will require impact-rated glazing and anchoring when you pull a permit. That means laminated glass with an interlayer, reinforced frame anchoring through the king studs, and a documented design pressure rating. We install PGT and Therma-Tru assemblies that carry the proper NOA and TAS documentation. You get a copy for your file, and we get the inspection passed.
Re-Casing and Jamb Repair
Salt air is not kind to steel and aluminum jambs. We regularly find thresholds rusted through at the corners, where bay moisture wicks up from the slab. A new door screwed into that corroded material is a door that will fail its wind-load test and sag within two years. We cut the rot out, treat the framing, and re-case the opening before the new door goes in. That’s included in our written price, not added at the door.
Door Replacement in Nassau Bay
Door replacement in Nassau Bay often means more than swapping a slab. The original aluminum sliding patio doors on these 1960s and 1970s homes have settled with the slab, corroded from bay humidity, and lost their thermal seals. A replacement that ignores those conditions will stick, leak, or fail inspection. Our typical slider replacement runs $3,200 – $9,500 installed, with the higher end covering impact-rated PGT or CGI assemblies, new jambs, and slab re-leveling in the door’s travel path.
Sliding Patio Door Re-Square and Install
Before any new slider goes in, we check the opening with a laser and a 6-foot level. In the older sections of Nassau Bay, we often find the track has settled half an inch low on the bay side. Installing a new sliding door into that opening without re-squaring means a door that rolls closed on its own, binds at the latch, and fails the Large-Missile Rating test. We re-square first. That’s the difference between a door that works and a door that passes.
Storm Door Retrofit on Existing Openings
Some Nassau Bay homeowners want a storm door for ventilation and light without replacing their existing entry. That works when the underlying frame is solid. We measure the reveal, check the threshold for level, and install Therma-Tru and ViewLux storm doors with proper drainage and closing hardware. If the original jamb is rotted, we’ll tell you before we sell you a storm door, because a storm door won’t fix what’s failing behind it.
Trusted Brands We Service in Nassau Bay
We stock and install products from PGT, CGI, Therma-Tru, CWS, ES Windows, ECO Window Systems, Mr-Glass, and ViewLux. For Nassau Bay’s wind-borne debris requirements, PGT and CGI carry the impact-rated assemblies we specify most often, while Therma-Tru covers quality front entries with the design pressure documentation needed for permit. We keep local parts inventory for the common sizes in this housing stock, so when your 1970s slider finally gives out, we’re not waiting two weeks on a factory order. The right product for the job, not the job forced into one product line.
Common Door Installation Problems We See in Nassau Bay Homes
- Corroded original aluminum jambs and thresholds. Galveston Bay humidity accelerates pitting and rust-through on the original single-pane aluminum slider frames. Installing an impact-rated door into that corroded material means the anchoring fails under wind load and the design pressure rating is void.
- Slab settlement out of square. These 1960s and 1970s patio homes sit on slab foundations that shift with Houston-area clay soil. A sliding door that sticks halfway, or a front door that won’t latch cleanly, usually means the opening itself is no longer square.
- Non-impact doors in wind-borne debris zones. Some homeowners had a basic door installed years ago without a permit. Nassau Bay enforces impact requirements on exterior openings now. If you’re selling the house or refinancing, the bank will catch it at inspection.
- Missing or undocumented wind-load paperwork. An impact door without the manufacturer’s NOA or TAS documentation doesn’t satisfy a wind mitigation inspector, and you lose the insurance credit. We document every rating and hand you the paper.

FAQs About Door Installation in Nassau Bay
It depends on your home’s location relative to the wind-borne debris zone. Nassau Bay’s building code requires impact-rated exterior openings in areas exposed to open bay wind load, and a Miami-Dade NOA or TAS rating is the documentation that satisfies most inspectors. A basic wind-rated door without an impact rating will fail in those zones. We’ll tell you what your specific address requires before you pull a permit. Call (325) 326-4211 for a site check and a written estimate.
Yes. We re-square the opening first. On San Sebastian Lane, our crew pulled a 1970s front door whose jamb had rusted through at the threshold from decades of bay moisture. We re-aligned the slab-settled frame, installed a new impact-rated PGT door with a laminated glass interlayer meeting Miami-Dade NOA, and documented the design pressure rating for the homeowner’s wind mitigation inspection. That’s standard procedure for us in Nassau Bay. The re-square work is included in the quote, not added on later.
An impact-rated door with documented Large-Missile rating and proper anchoring will typically qualify for a windstorm insurance premium credit through the Texas Windstorm Insurance Association or your private carrier. The key is the documentation: the NOA number, the design pressure rating, and proof the door is anchored to code. We provide all of that after the job. Call us for specifics on your carrier’s requirements.
A Large-Missile rated assembly has been tested to withstand a 9-pound 2×4 traveling at 34 mph, which is what a hurricane wind throws at an opening facing open water. A regular impact door passes a smaller-missile test or only a cyclic wind pressure test. For most Nassau Bay patio homes near the bay, the city and your insurer want Large-Missile. We specify PGT and CGI assemblies that carry the exact rating your opening needs, and we document it.
No. White corrosion on aluminum means the frame has oxidized through, and anchoring a new impact door to that material will fail under wind load. The frame has to come out, the rough opening has to be inspected for rot, and the new jamb has to be re-cased before the new door goes in. We do that work on nearly every original door in Nassau Bay’s older sections. It’s in the written price from the start. Call (325) 326-4211 and we’ll look at your opening and tell you what’s actually there.
