Why Juniper Windows & Doors Is Corte Madera’s Preferred Door Replacement Company
Homeowners in Corte Madera keep calling us back because we put the price in writing and then stick to it. Sean Mackey, who leads our team, set the standard early: if the number changes after we open the wall, the overage is our problem, not yours. That matters in Corte Madera, where older homes near the creek hide jamb rot that other contractors won’t discover until demolition day. We quote for what we expect to find and what we’ll do if the rough opening needs more work.
Our crews know the difference between a standard flange kit and a custom rebuild on a 1960s Madera Gardens ranch. We stock rot-resistant jamb material, composite shims, and stainless fasteners specifically because Corte Madera’s low-lying neighborhoods demand them. When you book with us, you get a live arrival time you can track, before-and-after photos, and a digital invoice. No four-hour windows, no no-shows.
Every Corte Madera project comes with the 365-Day Done Right Promise: parts and labor, in writing, for a full year. And if a repair fails, the second visit is free. That’s the Relay Standard, and it applies to every door we install from Larkspur to San Rafael.
Door Installers in Corte Madera
Door Installers in Corte Madera handle the physical work of removing your old door, prepping the opening, and setting the new unit square, plumb, and sealed. You need an installer when the existing slab is damaged, when the jamb has started to rot, or when you want to upgrade to an insulated fiberglass or impact-rated glass unit. In Corte Madera, a straightforward slab swap on a standard 36-inch opening runs $400 to $900 in labor, while a full frame replacement with custom sizing falls between $1,200 and $2,400 in labor.
Slab Replacement vs. Full Frame Rebuild
A slab replacement keeps the existing jamb and brickmold. It works when the framing is sound and the door itself is the problem. In Corte Madera homes built before 1980, we frequently find the brickmold has been absorbing moisture for decades. Once we pull the old slab, the jamb often tells a different story. We’ll show you photos before we proceed, so you’re deciding with your eyes, not our sales pitch.
Standard vs. Non-Standard Rough Openings
Older Corte Madera homes often have rough openings that don’t match modern door sizing. A stock 36-inch prehung door won’t fit a 78-inch tall opening without shimming, drywall repair, or a custom order. Our installers measure twice and order once. If the opening needs reframing, the permit requirement kicks in and we handle that paperwork for you.
Door Contractors in Corte Madera
Door Contractors in Corte Madera manage the whole replacement: measuring, ordering, obtaining permits, coordinating inspections, and installing. You need a contractor rather than an installer when the scope goes beyond a simple swap – a new sidelight, a header change, a rough opening that’s rotted through, or a door on a load-bearing wall. Contractors in Corte Madera generally charge $1,800 to $4,200 for a full exterior door replacement, including the unit, materials, labor, and permit fees.
Permit-Triggering Scopes and Final Inspections
Corte Madera’s building department requires a permit when the frame or header changes. Adding a sidelight also triggers one. Our team pulls the permit, schedules the inspection, and walks the job through to the final sign-off. A skipped permit on a door replacement can stall a future home sale, and Corte Madera buyers and their inspectors know exactly what to look for. We don’t cut that corner.
Moisture-Driven Jamb Rot Near the Creek
Doors in the low-lying neighborhoods around Corte Madera Creek take more moisture than doors up in the hills. A simple door swap becomes a full frame rebuild once the old jamb is pulled and the extent of the rot is visible. We quote for both scenarios on every estimate, so you’re never surprised. The written price includes the contingency: if the jamb is sound, you pay less. If it needs rebuilding, the number is already in the contract.
Trusted Brands We Service in Corte Madera
We install fiberglass entry doors from Therma-Tru, impact-rated units from PGT and CGI, and contemporary designs from ViewLux. For Corte Madera customers, we stock local replacement parts for these lines at our Bay Area warehouse, which means no waiting weeks for a hinge, weatherstrip, or threshold. If a component fails within the 365-day coverage period, we replace it fast – usually days, not weeks. You’ll find the right door for your home’s style, from a clean mid-century ViewLux on a Tamalpais Drive ranch to a classic Therma-Tru entry on a craftsman near the Village.
Common Door Replacement Problems We See in Corte Madera Homes
- Creek-side jamb rot: Homes in Madera Gardens and other low-lying areas near Corte Madera Creek see moisture wick into the jamb and brickmold. By the time the door sticks or the threshold feels soft, the framing underneath has usually been rotting for years.
- Non-standard rough openings: Pre-1970s Corte Madera homes were often framed before standard door sizing. A modern prehung unit rarely drops into the old opening without shimming, trimming, or reframing.
- Design pressure failures on marsh-adjacent lots: Wind-driven rain off the marsh can push water through a door that wasn’t rated for the exposure. We recheck design pressure requirements on every creek-side and marsh-adjacent install.
- Permit complications from past work: We sometimes find previous door replacements in Corte Madera that were done without a permit, leaving the header undersized or the flashing improper. That prior work has to be corrected before the new door passes inspection.
Pricing for Door Replacement in Corte Madera, CA
Here’s the honest math. A basic fiberglass slab replacement in Corte Madera runs $1,400 to $2,200 total. A mid-range Therma-Tru or ViewLux prehung door with new jamb and hardware lands around $2,500 to $3,800. A full custom rebuild – rotted framing, new rough opening, impact-rated glass, permit and inspection – can reach $4,200 or more. What moves the number: whether the jamb is salvageable, whether your rough opening is standard, whether you’re adding glass, and whether the permit triggers a header change.

FAQs About Door Replacement in Corte Madera
Yes, if the frame or header changes, or if you’re adding a sidelight. Corte Madera’s building department requires a permit for those scopes. A slab-only swap on an existing sound jamb typically doesn’t need one. We pull permits when required and schedule the inspection. Call (682) 281-2168 and we’ll tell you upfront whether your project needs one.
Corte Madera’s low-lying neighborhoods sit close to Corte Madera Creek and the marsh, where seasonal moisture and occasional storm surge keep ground-level air humid. Older homes built before modern flashing and sill pans were standard absorb that moisture into the jamb. We rebuild those jambs with rot-resistant material and elevated thresholds rather than reinstalling a door that will fail the same way in five years.
Most Corte Madera door replacements take two to four weeks from written estimate to final sign-off. Custom-sized units or impact-rated glass can add a week or two. Permit inspections typically take a few days to schedule once the work is complete. We’ll give you a realistic calendar in your written quote.
The only thing that typically changes the price is what we find when we open the wall: rotted jamb, non-standard rough opening, a header that needs reinforcement, or prior unpermitted work that has to be corrected. That’s why we include these contingencies in your written price before we start. You’ll never see a change order for something visible at the time of the estimate. Call (682) 281-2168 for an exact quote.
Yes. We install PGT and CGI impact-rated units built to resist wind-borne debris, and we use low-E insulated glass on doors with glazing. For creek-side and marsh-adjacent lots, an impact-rated door with a proper sill pan is the right call. We’ll show you the difference in light transmission and U-factor before you choose.
