Windows & Doors Services in Corte Madera, CA
If you live in Corte Madera, you already know what the bay air does to a window frame. The salt-laden breeze that drifts off the tidal marshes east of Highway 101 works its way into aluminum tracks, sill hardware, and door thresholds. What starts as a slider that drags in July becomes a frame pitted and seized years before its time. We repair and replace windows and doors across Corte Madera, and we answer the phone when you call: (888) 635-0804.
Most Corte Madera homes were built between the late 1940s and early 1970s. That means single-pane aluminum sliders, original glass patio doors, and hardware that has been fighting salt air for fifty years or more. We know those houses. We know which side streets near the marsh see the worst corrosion, and we know which replacements hold up along the bay. That’s the difference between a company that happens to work in Corte Madera and one that reads the particular failure patterns of Corte Madera’s housing stock.

Why Corte Madera Homeowners Choose TruePane Windows & Doors
TruePane was founded in 2008 by second-generation glazier Dale Kessler. But the craft runs longer than that. Dale’s father set glass before him, and the rule that still governs every installation is the one scrawled on the shop whiteboard: if the pane is not true, the job is not done. That is not a slogan. It is a measurement standard applied to every sash, every threshold, every mitered corner we set in Corte Madera.
Homeowners in areas like Chapman Park and Madera Gardens have called us because a previous install left them with a fogged seal or a door that binds when the weather turns. They want the work done correctly the first time, by a company that will still answer the phone if something goes wrong. We have been serving local communities since 2008 through Dale’s heritage and craft tradition. Every Corte Madera job is covered by the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves the driveway. No paperwork fights. No arguing.
We hire local, train apprentices into journeymen, and act like a company that plans to be in Corte Madera in thirty years, because that is the plan. A live person answers the phone 24 hours a day, 7 days a week. No voicemail tree, no callback form, no regional call center routing you away from someone who knows Corte Madera.
Windows & Doors Services We Offer in Corte Madera
Window Installation
New window installation in Corte Madera starts with measuring every opening twice, not once. We quote manufacturer lines side by side on paper so you see exactly what you are buying before any glass is ordered. Learn more about our Window Installation in Corte Madera.

Door Installation
Entry doors and patio sliders carry the brunt of Corte Madera’s salt air, especially east of 101. We set thresholds level and true, with corrosion-resistant hardware selected for bayshore exposure. Learn more about our Door Installation in Corte Madera.

Window Replacement
Replacing an original single-pane aluminum slider is more than an upgrade. In Corte Madera it is often a removal job for a frame that has seized in its own track. We shim, square, seal, and register both warranty layers before we leave the driveway. Learn more about our Window Replacement in Corte Madera.

Impact Windows & Doors
For homes that want storm-rated protection without sacrificing the view, we install Impact Windows & Doors in Corte Madera from manufacturer lines we know well. We are authorized installers for PGT and CGI, and we quote them side by side so the difference is on paper, not hidden in a sales pitch.

Energy-Efficient Windows
Corte Madera sits in Title 24 Climate Zone 3, which means marine-influenced U-factor and SHGC thresholds apply to any permitted replacement. The original single-pane units in most older homes here cannot meet those standards, which is why we offer Energy-Efficient Windows in Corte Madera, and we do not pretend otherwise.

Sliding & Patio Doors
Sliding & Patio Doors in Corte Madera from the 1950s and 1960s are common, and many of them have aluminum frames pitted by decades of bayshore air. We replace tracks when salvaging a frame makes sense, and replace the entire unit when it does not.

Glass Railing Systems
Deck and staircase railings near the marsh take a beating. We install Glass Railing Systems in Corte Madera with posts and hardware selected for salt exposure, not for an inland climate.

Custom Windows & Doors
For openings that are not a standard size, we order custom units and set them ourselves. ES Windows is one of the lines we carry for homeowners who want something tailored to a specific wall, not adapted to it.

Neighborhoods We Serve in Corte Madera
TruePane crews work across Corte Madera’s 94925 zip code, from the bayside streets near San Francisco Bay to the hillside lots off Tamalpais Drive. We are familiar with the original tract layouts that define each neighborhood, and we schedule based on where a job sits relative to the marsh. Typical response time for estimates in Corte Madera is one to two business days, depending on the season.

Why Corte Madera’s Climate & Housing Affect Windows & Doors
Corte Madera’s eastern residential neighborhoods sit directly adjacent to San Francisco Bay tidal marshes. That location means chronic, salt-laden bay breezes that corrode aluminum window frames, sill hardware, and door thresholds far faster than in inland Marin towns like San Rafael or Novato. It is not a gradual wear issue. On bayside streets, we routinely find aluminum-frame windows pitted and seized within 10 to 15 years of installation, when the same unit might have lasted 20 to 25 miles inland.
The housing stock compounds the problem. Most of Corte Madera’s neighborhoods were built between the late 1940s and early 1970s as post-war ranch tracts with single-pane aluminum sliders and glass patio doors. Those units are now 50 to 70 years old. They are structurally compromised by coastal corrosion and dramatically out of compliance with current California Title 24 energy requirements. The marine layer and salt air also shorten the effective lifespan of lower-grade replacement windows installed without corrosion-resistant framing. For any job within a half-mile of the marsh, we spec fiberglass or cellular PVC frames as a baseline, not as an upsell. That is a standard we would not apply by default just a few miles inland in Larkspur or Kentfield, and it is the kind of local judgment that comes from actually working these streets.
Pricing for Windows & Doors in Corte Madera

FAQs About Windows & Doors in Corte Madera
Most single window replacements in Corte Madera run between $650 and $1,400 per window, depending on frame condition, glass package, and whether salt-air corrosion has to be removed first. Full-home replacements on a typical ranch with 8 to 12 openings run from $8,000 to $18,000. Call (888) 635-0804 for an exact quote. Estimates are free.
It will not. We write line-item quotes before the job begins and stand by them. The only exception is hidden structural damage found behind the frame, and we stop and walk you through that in writing before doing anything further. No surprise line items, no change orders slipped into the final bill.
When a Corte Madera job requires a permit, we pull it. Corte Madera sits in Title 24 Climate Zone 3, and any permitted replacement must meet specific U-factor and SHGC requirements. We make sure the units we install are compliant, and we handle the paperwork so you are not chasing the building department.
Salt-laden bay breezes off the tidal marshes east of Highway 101 accelerate oxidation on aluminum frames, sill hardware, and thresholds. On bayside streets, we routinely see frames pitted and seized within 10 to 15 years, when the same frame might last 20 to 25 inland. For homes within a half-mile of the marsh, we recommend fiberglass or cellular PVC frames as a baseline.
Yes. We work with custom manufacturers, including ES Windows, to produce units that match the sightlines and proportions of original windows on Madera Gardens and Chapman Park ranches. We measure every opening twice and order to spec, not to the nearest standard size. Call (888) 635-0804 and we will tell you what is possible for your specific openings.

What Corte Madera Customers Say
"Two entry doors. Showed up when they said, second day was a half day like they said, and the painter they recommended confirmed the frames were dead plumb. The financing was explained in actual dollars, not a brochure."
- Janet R."Impact windows on the whole house. They handled the permit, the inspection, and gave me a folder with every approval number for the insurance company. My windstorm premium dropped enough to notice."
- Bill T."Whole-house window replacement at 71 years old is not something you want to do twice. Dale walked the house himself for the quote. Crew was the same three men all four days, and the foreman knew every window by room."
- Pat and Ray L.
