Why Westlight Windows & Doors Is Corte Madera’s Preferred Door Installation Company
Westlight Windows & Doors has operated as an independently owned and operated Kingswell location since 2009, and Owen Satterfield leads our team with a simple rule: say the price before the work, show up when you said you would, and come back if it fails. Corte Madera homeowners call us because we carry eight manufacturer lines, including Therma-Tru, PGT, and ViewLux, so we are not forcing one brand onto a house that needs something else. Every job in Corte Madera gets the Kingswell Guarantee in writing: a committed arrival window, a clean job site, a written price before any work begins, and a written guarantee on the completed work.
Our Door Installation team has repaired and replaced doors throughout Corte Madera, from the ranch-style homes on the bay flats to the contemporary builds up near the Larkspur border. When a Corte Madera homeowner tells us a door sticks in July and latches wrong in January, we know what that means: differential settlement in the bay mud. That local knowledge changes how we scope the job. A call comes in, a real person picks up the phone 24/7, and we schedule a visit with background-checked, uniformed technicians. No vague ranges. No revised invoice at the door.
Door Repair in Corte Madera
Door Repair in Corte Madera typically costs $180-$480 for hinge replacement, latch realignment, strike plate adjustment, or threshold resealing on a standard exterior door, and $500-$1,100 when the repair involves re-squaring a racked frame or replacing a rotted sill. We start every repair by checking the rough opening for settlement, because in the bay-fill flats east of US-101, a door that suddenly drags is rarely just a hinge problem. It’s usually the frame slowly moving.
Racked Frames and Salt-Corroded Hardware
A door in a 1960s Corte Madera rancher east of US-101 sits on engineered fill over bay mud. Over decades, the fill settles unevenly and the rough opening twists. That means the latch misses the strike, the top of the slab rubs the jamb, and the homeowner keeps adjusting the hinges hoping it will fix itself. It won’t. We shim and square the jamb, re-hang the slab, and reset the hardware so the door closes like it should.
Then there is the salt. Afternoon breezes off San Francisco Bay carry salt and moisture across the eastern flats every day. Steel hinges pit, kickplates rust from the edges, and wood thresholds rot from the bottom up. When we repair a door in Corte Madera, we default to stainless or coated hardware and a marine-grade sill, because plain galvanized parts have a short life here.
Threshold and Weatherseal Failures
Wind-driven rain and a persistent marine layer push moisture past original door pans and thresholds. The result is a swollen jamb, a door that sticks, and often water staining on the interior floor near the entry. Westlight repairs these by pulling the old threshold, checking the subfloor for rot, and installing a sealed drainage detail that sheds water away from the sill rather than under it.
Exterior Door Installation in Corte Madera
Exterior Door Installation in Corte Madera runs $1,200-$4,200 installed for most single-door replacements, depending on whether the rough opening is square, whether the existing frame is salvageable, and what material the homeowner chooses. Marine-grade fiberglass from Therma-Tru or an impact-rated steel door from PGT sits at the upper end of that range. A basic builder-grade steel slab with a weatherstrip and hinges sits at the lower end. We give every Corte Madera homeowner a written price before work starts, so the number on the quote is the number on the final invoice.
The Right Material for Bay Air
Corte Madera’s eastern flats face San Francisco Bay directly. Salt-laden air hits every exterior door on those streets daily, and it does not forgive lightweight steel or unsealed wood. For a home east of US-101, we recommend a marine-grade fiberglass door with stainless hinges and a composite threshold as the baseline. West of 101, where the hills block much of the salt spray, homeowners have more flexibility, but humidity is still a factor. We walk each client through the tradeoffs with actual prices, not vague ranges, and we stock multiple brands so the right product is matched to the job.
Rough Opening Squaring and Prep
On a ranch-style home in the flats east of US-101, our crew replaced a salt-corroded lightweight steel exterior door with a Therma-Tru fiberglass door, stainless hinges, and a marine-grade sill. The frame was racked about 3/8 inch out of plumb from decades of bay-mud settlement, so we shimmed and squared the jamb before hanging the door. We also sealed the threshold with a drainage detail that sheds wind-driven bay moisture away from the sill. That prep work adds to the labor line on a quote, and any honest installer in Corte Madera will tell you it is standard for the older houses east of 101. We scope it before we quote, not after.
Trusted Brands We Service in Corte Madera
Westlight installs doors from eight manufacturer lines, and for Corte Madera homeowners we lean on three of them most often. Therma-Tru fiberglass doors handle the salt and humidity with an engineered composite core and a rot-resistant frame. PGT builds impact-rated doors for homeowners who want storm protection along with daily performance. ViewLux offers aluminum and vinyl options with clean sightlines for contemporary homes up in the hills. We keep common parts and hardware in local stock for Corte Madera customers, so repair turnarounds are measured in days, not weeks. If you call (903) 354-7134, a real person answers and can schedule you directly.
Common Door Installation Problems We See in Corte Madera Homes
- Frames racked out of plumb by settlement. The bay-fill flats east of US-101 are built on engineered fill over bay mud, and decades of differential settlement twist rough openings. Latches miss strikes, doors drag in summer, and gaps open up at the top corners. We re-square and shim every jamb before hanging the slab.
- Salt corrosion on hinges, handles, and kickplates. Daily salt-laden breezes off San Francisco Bay pit steel hardware within a few years. Homeowners east of 101 should plan on stainless or coated hardware as a baseline, not an option.
- Rotted wood thresholds and sills. High humidity, wind-driven rain, and a persistent marine layer push moisture past old door pans. The threshold rots from the bottom up, the door starts sticking, and interior flooring near the entry takes on water stains.
- Swollen jambs from moisture intrusion. When a door pan fails or a weatherstrip tears, moisture works into the jamb and swells it. The door sticks, the latch misaligns, and the cycle gets worse each winter storm season. We replace the failed pan and reseal the rough opening before reinstalling the door.
Pricing for Door Installation in Corte Madera, CA
Most single exterior door replacements in Corte Madera run $1,200-$4,200 installed.

Door repairs cluster in the $180-$480 range for hardware, latch, and seal work, and $500-$1,100 when we are re-squaring a racked frame or replacing a rotted sill.

FAQs About Door Installation in Corte Madera
The bay-fill flats east of US-101 were built on engineered fill over bay mud in the 1950s and 1960s, and that fill settles unevenly over time. Door frames rack out of plumb, latches miss strikes, and slabs drag seasonally. Combined with daily salt-laden bay breezes that corrode hardware and rot thresholds, doors on the flats simply wear out faster than doors in the hillside neighborhoods west of town. If your door is sticking, call (903) 354-7134 for a repair estimate; we check the rough opening first.
For most direct door replacements, where the rough opening stays the same and no structural changes are made, the Town of Corte Madera does not require a building permit. If the opening is enlarged, a header is modified, or the job is part of a larger addition, a permit is typically required. Westlight handles the permit process when one is needed, and every inspection is passed before we call the job done. We will tell you exactly what applies to your project before any work starts.
Marine-grade fiberglass, like Therma-Tru’s composite doors, holds up best against the salt-laden breezes and high humidity that define Corte Madera’s eastern flats. Fiberglass will not rot, will not corrode, and will not swell the way wood and lightweight steel will in this microclimate. Pair it with stainless or coated hinges and a composite threshold, and you have a door built for the bay front.
Yes. For acreage properties, detached shops, and ADUs in and around Corte Madera, we install exterior doors the same way we do for primary residences, with pricing that reflects the additional access work, grading, and drainage control that these structures sometimes require. We scope the site before we quote so you are not surprised by a change order. Your written estimate covers the access, the prep, the door, the hardware, and the cleanup.
Corte Madera’s persistent marine layer keeps ambient humidity elevated year-round, and when that combines with wind-driven rain, moisture gets driven past old door pans and thresholds. Hinges rust, handles pit, and wood sills rot from the bottom up. We install sealed drainage details under every threshold, and we default to stainless or coated hardware for east-facing flats. If your threshold is showing rot or your door sticks after every storm, call (903) 354-7134 and we’ll take a look.
