Why TruePane Windows & Doors Is Corte Madera’s Preferred Impact Windows & Doors Company
We’ve worked enough Corte Madera ranch homes to know what’s behind the stucco before we cut it open. The original aluminum sliders on Madera Boulevard, Lakeside Drive, and the streets running east toward the marsh were never built for salt air, and most of them gave up their seals years ago. Homeowners in Corte Madera call us because we say what we mean on the first visit. We write both warranty layers down on paper, register them before the truck leaves, and stand behind the work for 90 days under the Impact Windows & Doors Done Right Promise. No arguing, no fine print that covers neither. Dale Kessler founded TruePane in 2008 on a rule that’s still on the whiteboard: if the pane is not true, the job is not done.
Our crews are background-checked and uniformed. The phone gets answered by a live person, 24 hours a day, seven days a week. Not a voicemail tree, not a regional call center. When a Corte Madera homeowner calls about a seized slider or a door that binds in July, we pick up.
Our Impact Windows & Doors Services in Corte Madera
Hurricane Impact Windows
Most Corte Madera homes built between the late 1940s and early 1970s still carry single-pane aluminum windows that fail current Title 24 Climate Zone 3 thresholds by a wide margin. A permitted replacement means hitting mandated U-factor and SHGC numbers, which the originals cannot do. We install impact-rated units with laminated glass and corrosion-resistant framing, sized for the marine exposure your house actually gets, not a generic spec from a catalog.

Impact Sliding Glass Doors
Corte Madera Sliding & Patio Doors on post-war ranches are the single most common point of failure we see. Salt-laden bay breeze pits the aluminum frames, seizes the rollers, and leaves the door so bound you have to shoulder it open. We replace those units with fiberglass or cellular PVC-framed impact sliders, set in reframed and reflashed openings. The door opens with one hand when we’re done, and it won’t corrode for decades.

Impact Entry & French Doors
Entry doors on the bay side of Corte Madera take the same salt abuse as windows, and the thresholds are usually the first thing to go. Rusted sill hardware, swollen jambs, and failed weatherstripping let in the marine air year-round. We install Custom Windows & Doors - Corte Madera with impact-rated entry and French options, stainless hardware and proper sill flashing. If the rough opening needs reframing, you’ll know before we cut, not after.

Impact Garage Doors
A garage door on a Corte Madera bay-side home is a wind-load liability if it was never braced for coastal conditions. We install and reinforce impact-rated garage doors that handle the wind pressures this area sees during winter storm season. Most of the older doors we pull off Corte Madera homes were never designed for uplift at all.
We also handle Impact Windows & Doors in Corte Madera code compliance work, including wind mitigation inspections and the paperwork your insurer may require.

Trusted Brands We Service in Corte Madera
TruePane is an authorized installer for more than a dozen manufacturer lines, and for Corte Madera’s bay-side exposure we lean on Corte Madera Glass Railing Systems and other products built for marine conditions. CGI and CWS both make impact glazing systems with corrosion-resistant framing that hold up against salt air. ES Windows builds a fiberglass line we specify often for homes within a half-mile of the marsh. We quote manufacturer lines side by side on paper so you see exactly what you’re buying, and we stock common parts locally so a Corte Madera repair doesn’t wait on a backorder from the East Coast.
Common Impact Windows & Doors Problems We See in Corte Madera Homes
- Seized aluminum sashes and frames. The constant salt-laden breeze off San Francisco Bay pits aluminum window frames and oxidizes the jamb hardware in 10-15 years instead of the expected 20-25. By the time we’re called to a bay-side home, the window often won’t open at all.
- Hidden rot behind the frame. The original builders of Corte Madera’s 1950s and 1960s tracts used no flashing tape behind window frames. Once the seal fails, water works into the rough opening for years. The rot is invisible until we pull the unit, and then it’s obvious.
- Failed patio slider rollers and tracks. Salt corrosion seizes the roller assemblies on glass sliders, so the door drags or jams. Homeowners put up with it for years, then call us when the door won’t lock or close against a winter storm.
- Title 24 non-compliance on every original unit. Climate Zone 3 requires specific U-factor and SHGC thresholds that no single-pane aluminum window from the 1960s can meet. A permitted replacement triggers the full compliance path, so the job is a thermal retrofit as much as a window swap.

FAQs - Impact Windows & Doors in Corte Madera
The short answer is salt. Corte Madera’s eastern residential streets sit directly against the tidal marshes of San Francisco Bay, and the constant marine breeze carries salt that pits and oxidizes aluminum frames and sill hardware. We routinely see aluminum windows on Madera Boulevard and Lakeside Drive seize within 10 to 15 years, while identical units just a few miles inland in Larkspur or San Rafael make it to 20 or 25. That’s why we spec fiberglass or cellular PVC as the baseline framing material for any bay-side impact window or door replacement. Call (888) 635-0804 for an exact assessment of your home’s exposure.
Yes. Corte Madera sits in Title 24 Climate Zone 3, a marine zone with mandated U-factor and SHGC thresholds for any permitted window replacement. The original single-pane aluminum windows in most Court Madera ranch homes fail those thresholds by a wide margin, so a permitted replacement must meet current energy performance standards. We handle the compliance paperwork as part of the job. Call (888) 635-0804 and we’ll walk your project through the numbers before you sign anything.
Expect to find what we usually find: no flashing tape, a soft sill, and a rough opening that needs at least some repair. The builders of Corte Madera’s post-war tracts didn’t flash window openings, so decades of moisture have worked behind the frame. We plan for it. Our contract includes a written allowance for reframing and waterproofing, and if we find something beyond that allowance, you get a change order with a price before we pick up a saw. No surprise line items on the bill. Call (888) 635-0804 to schedule your free estimate.
We price it in writing before we touch it. Every Corte Madera job starts with an inspection, and the contract includes a line-item allowance for the rot repair and reframing work that older bay-side homes almost always need. If the permit triggers a code upgrade we didn’t anticipate, or the rough opening is worse than the inspection showed, we stop and hand you a written change order with a set price. You approve it, or we don’t do the work. There’s never a surprise on the final invoice. Call (888) 635-0804 for a free estimate built on the same principle.
Because aluminum corrodes in salt air, and fiberglass doesn’t. We pivot to fiberglass or cellular PVC for any home within a half-mile of the tidal marsh because we’ve seen what happens to aluminum there: pits in the frame, seized hardware, and seals that fail inside a decade. Fiberglass holds its finish, keeps its dimensional stability, and carries an impact rating without the corrosion risk. The upfront cost is higher, but the replacement cycle is three times as long. Call (888) 635-0804 and we’ll quote both materials side by side so you can see the numbers for your specific openings.
When you’re ready to talk, call (888) 635-0804. A live person answers. We’ll schedule a walkthrough in Corte Madera, write you a free estimate with real numbers, and stand behind the work under the Done Right Promise. If the pane is not true, the job is not done.
