Fast, Reliable Window Installation Across Corte Madera
Window installation in Corte Madera runs $850 to $2,800 per window, depending on the unit type, frame material, and whether your home sits inside the town’s wildland-urban interface (WUI) zone. Most replacements take one day per window once permits clear, with a full 10-window house wrapping in two to three weeks from contract to final inspection. We’re Juniper Windows & Doors, and our crews work Corte Madera neighborhoods from Chapman Drive to the ridge streets above Paradise Drive every week. If you’re thinking about Corte Madera Window Replacement, call (682) 281-2168 and we’ll give you a written price before anything starts.
Why Juniper Windows & Doors Is Corte Madera’s Preferred Window Installation Company
Corte Madera homeowners keep our number because we don’t make them guess. Every job gets a written price up front, and the 365-Day Done Right Promise means if something isn’t right within a year, we fix it – parts and labor, in writing. Sean Mackey leads our window and door teams, and he’s built a crew of background-checked, uniformed technicians who show up when they say they will. You’ll get a live arrival time, photo updates while we work, and a digital invoice you can pay from your phone.
We stock parts for Corte Madera jobs locally, which means a blown seal on a ViewLux slider doesn’t turn into a two-week wait for a freight shipment from the East Coast. Our dispatchers coordinate from the San Francisco Bay Area office, and the crews that roll into Corte Madera know the housing stock here: 1950s and 60s tracts with single-pane wood frames, 70s split-levels off Chapman, and newer hillside builds that fall under WUI glazing rules. That local knowledge changes what we spec and how we bid.
Double Hung Windows in Corte Madera
Double Hung Windows are the most common replacement in Corte Madera’s 1950s-through-1970s homes, where original single-pane wood sashes have swollen, warped, or been painted shut for decades. Both the top and bottom sash operate, which gives you ventilation control that fixed windows don’t. In Corte Madera, we typically install vinyl double hungs with low-E glass and argon-filled insulated glass units, running $850 to $1,900 per window installed. If your home is on a hillside parcel inside the WUI overlay, expect the glazing spec to shift toward ember- and radiant-heat-rated assemblies, which can add $150 to $400 per unit.
The bigger cost driver we see is what’s behind the stops. Corte Madera’s older wood-frame homes hide dry rot and out-of-square jambs that a flat per-window quote misses. We field-measure every rough opening before ordering, then sister or shim the jamb as needed so the new window sits square and flashes clean.
What Replacing Double Hungs Actually Involves
We pull the interior stops, remove the old sashes and weights, then inspect the jamb for rot. If the wood is solid, we set the new window, insulate the perimeter, flash the exterior flange, and trim the opening back out. If the jamb crumbles when we pull the stops – which happens often on Corte Madera’s east-facing homes that catch bay wind and morning fog – we cut out the bad wood and replace it before setting the unit. The whole process takes a morning for a typical double hung, and you’ll get before-and-after photos in your job file.
When Corte Madera Homeowners Make the Switch
Most people call us when their sashes won’t stay up, drafts are obvious in winter, or the glass fogs between panes. Others are preparing for PG&E rate hikes and want the cooling-load cut that comes from low-E glass – typically 20 to 30 percent on west-facing windows in Corte Madera’s afternoon sun. Some are selling, and a window replacement in Corte Madera is one of the few improvements that appraisers notice line-by-line. Whatever the trigger, our team at Window Installation handles the whole job from permit to final inspection.
Vinyl Windows in Corte Madera
Vinyl Windows are the workhorse choice in Corte Madera, especially for homeowners who want solid thermal performance without repainting ever again. A standard vinyl double hung or slider in Corte Madera runs $700 to $1,500 installed; larger picture or bay units push higher. Vinyl frames don’t rot the way old wood does, which matters in Corte Madera’s damp winter months and fog-heavy summers off the bay. We pair them with low-E glass and argon fills as standard, not as an upsell, because Title 24 compliance in Marin County makes bare clear glass a nonstarter on permitted replacements.
One thing Corte Madera homeowners appreciate about vinyl is the maintenance math. No scraping, no painting, no swelling in wet winters. The frames get wiped down twice a year and that’s the whole program. And for hillside homes in the WUI overlay, vinyl frames are compatible with ember-rated glazing assemblies, so you don’t have to give up thermal performance to hit fire code.
Sizing and Fit on Older Corte Madera Homes
Corte Madera’s tract homes from the 50s through 70s aren’t always square. We’ve measured rough openings that are off by a quarter-inch or a half-inch from nominal – enough to cause reorders and calendar slips if someone orders from blueprints or photos. Our process is simple: we measure the as-built opening ourselves, order to that number, and set the frame level and square with shims so the sash operates smoothly for years. A vinyl window installed square with a proper flashing job will outlast two repaints on a wood frame.
Energy Performance in Corte Madera’s Climate
Corte Madera gets real sun off the bay in summer and cold, damp air in winter. Vinyl windows with low-E glass and argon fill perform well in both directions: the low-E coating blocks solar gain during afternoon heat, and the argon layer slows heat loss when the marine layer settles in. We size the package to your home’s orientation and whether the window faces afternoon sun or shaded redwood canopy. Get it right and the windows pay for themselves in comfort before the energy savings even show up on the PG&E bill.
Trusted Brands We Service in Corte Madera
Juniper Windows & Doors installs Window Installation in Corte Madera from a short list of brands we trust for this climate: ViewLux, PGT, and CWS. ViewLux sliders and double hungs are popular in Corte Madera for their clean sightlines and solid thermal numbers. PGT carries impact-rated and WUI-compliant lines that matter on hillside parcels. CWS gives us access to custom-sized picture and casement units without a six-week lead. Because we stock parts for these brands locally, a latch replacement or a seal repair on a ViewLux unit doesn’t mean waiting on a freight truck. Sean and our crews know these product lines down to the U-factor on each glazing package, which means the spec we put in your written quote is the one that gets installed.
Common Window Installation Problems We See in Corte Madera Homes
- Dry rot hidden behind window stops. Corte Madera’s older wood-frame homes often have rot in the jambs and sills that’s invisible until the old window comes out. Fixing it mid-job adds carpentry hours and flashing work that flat per-window bids miss, so we inspect before we quote.
- WUI glazing requirements on hillside parcels. The ridge streets above Paradise Drive and the Chapman Drive corridor fall under fire-authority rules that standard low-E insulated glass won’t always satisfy. Specifying the wrong assembly either fails inspection or leaves a home under-protected.
- Out-of-square rough openings on 1950s-70s tract homes. Corte Madera’s original framing was rarely perfect, and half-inch discrepancies are common. Ordering to nominal sizes from a blueprint instead of field-measuring leads to reorders, a second permit revision, and a two-to-three-week slip.
- Fogged or failed seals on original double-pane units. We see a lot of late-90s and early-2000s replacements in Corte Madera now failing between the panes. The glass is still intact but the insulating gas is gone, and the only fix is a full unit replacement, not a repair.

FAQs About Window Installation in Corte Madera
Yes. Corte Madera’s building department requires a permit for window replacement, and if your home is in the WUI overlay, the permit review includes a glazing compliance check against ember and radiant-heat requirements. We pull the permit, schedule the inspection, and close it out with the town. Call (682) 281-2168 and we’ll handle the paperwork as part of your written quote.
Plan on two to four weeks from signed contract to final inspection for a whole-house window replacement in Corte Madera. Permit review typically takes three to ten business days depending on whether the property is in the WUI overlay. Once the permit clears, installation runs one day per window for standard units, with final inspection scheduled within a few days after the last window goes in.
Two things: hidden rot in the jamb or sill that requires carpentry, and out-of-square rough openings that need shimming or sistering. Both are common in Corte Madera’s 1950s-70s wood-frame homes. We inspect each opening before we give you a written number, so these costs are in your quote up front. If we do find something unexpected mid-job, we stop, show you photos, and get your sign-off on a revised written price before continuing. No surprises at the door.
Not for standard flatland parcels. Impact-rated glass is a hurricane product and Corte Madera isn’t in a wind-borne debris zone. What hillside homes do need, if they’re in the WUI overlay above the Larkspur Ferry corridor, is ember- and radiant-heat-rated glazing, which is a different assembly than impact glass. We’ll tell you which applies to your street in the first five minutes of the estimate call.
We install ViewLux, PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, and Therma-Tru, which gives Corte Madera homeowners real options across vinyl, aluminum, and composite lines without ever being stuck with a compromise unit. For this market, we most often specify ViewLux for thermal performance, PGT for WUI compliance, and CWS for custom sizing. Call (682) 281-2168 and Sean’s team will spec the right brand and glazing package for your home’s orientation and zone.
