Windows & Doors Services in Windsor, CA
Window and door work in Windsor, CA means dealing with two things most towns don’t face: the Russian River wind corridor, and a fire-zone building code that inspectors actually enforce. A standard replacement job isn’t enough here. The glazing, the frame rating, the seal tightness all have to meet California’s Chapter 7A WUI standards or the job won’t pass. TruePane Windows & Doors handles that paperwork and that standard on every install in the 95492 zip code, and a live person answers at (888) 635-0804 when you call to talk through what your house needs.

Why Windsor Homeowners Choose TruePane Windows & Doors
Windsor isn’t a town where people cycle through contractors. Homeowners here remember which companies showed up after the Kincade Fire evacuations, which ones quoted honestly, and which ones disappeared when the rebuild paperwork got complicated. TruePane has been doing this work long enough that the second-generation glazier who founded the company, Dale Kessler, keeps one rule on the whiteboard: if the pane is not true, the job is not done. That applies whether we’re measuring an opening in the older streets off Old Redwood Highway or a tract house up near Foothill Regional Park.
Every job carries 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, no fine print that covers neither. Windsor homeowners in the newer subdivisions east of Highway 101 and the established neighborhood pockets west of the Town Green call us for the same reason: a square deal, written down, with a company that answers the phone.
Windows & Doors Services We Offer in Windsor
Window Installation
New construction or retrofit, every window opening gets measured twice before we quote. We set frames level and plumb, flash them against Windsor’s driven autumn rain, and register the warranty paperwork the same day. Learn more about our Window Installation in Windsor.

Door Installation
Entry doors, interior doors, and door systems that have to hold their line through decades of thermal cycling. We check the rough opening, the reveal, and the threshold, because a door that binds in July was hung wrong, not built wrong. Learn more about our Door Installation in Windsor.

Window Replacement
The bulk of our work in Windsor. If your home was built in the mid-90s through mid-2000s, the original builder-grade dual panes are at the end of their life, and we replace them with units rated for this fire zone, not just whatever fit the old opening. Learn more about our Window Replacement in Windsor.

Impact Windows & Doors
Impact Windows & Doors in Windsor use impact-rated glazing and reinforced frames that meet Chapter 7A requirements without making your house look like a bunker. We walk you through the rating numbers so you know exactly what passes inspection in Windsor before we order anything.

Energy-Efficient Windows
Energy-Efficient Windows in Windsor use Low-E coatings, argon fills, and tight frames that hold their seal through the area’s 30-degree daily temperature swings. The goal is simple: a house that costs less to cool in August and doesn’t fog up between the panes by year five.

Sliding & Patio Doors
Sliding & Patio Doors in Windsor often fail when they’re those 1990s units with worn rollers and dragging tracks-a common problem in the town’s tract-era housing stock. We replace or rebuild them with hardware that actually glides, and frames that seal against the afternoon wind.

Glass Railing Systems
Glass Railing Systems in Windsor include frameless and semi-frameless options for decks, stairways, and pool areas. Tempered, code-compliant, and installed so the glass doesn’t move when the wind hits it.

Custom Windows & Doors
Odd openings, arched tops, specific sightlines. We order custom units through authorized manufacturer lines so the fit is right the first time, not shimmed and caulked into a rough guess.

Neighborhoods We Serve in Windsor
Our crews work throughout Windsor, from the established streets west of the Town Green to the newer developments east of Highway 101 and the hillside lots near Foothill Regional Park. Typical response time for a Windsor estimate visit is within a day or two, depending on the week’s schedule.

Why Windsor’s Climate & Housing Affect Windows & Doors
Windsor sits in the Russian River wind corridor, where afternoon thermal drafts funnel marine air inland from the Pacific. That creates persistent pressure cycling on window and door frames, and it’s one reason fogged seals show up early in Windsor homes even when the units were decent quality. Add the 30 to 40 degree summer temperature swings between the cool foggy morning and the hot dry afternoon, and glass-to-frame seals get worked harder here than in towns closer to the coast or fully inland.
The housing stock adds another layer. Windsor incorporated in 1992 and grew fast through master-planned tract development in the mid-90s and 2000s. That means the dominant housing stock is now 20 to 30 years old, which is exactly when original builder-grade vinyl dual panes start failing. Fogged glass, warped frames, sliding doors with shot rollers. If your house is in that age range and you haven’t touched the windows, you’re on borrowed time.
Pricing for Windows & Doors in Windsor
Window costs in Windsor run a wide range because the WUI requirements add a layer most towns don’t carry. Here’s what we see on the ground:
- Standard dual-pane replacement window (vinyl, WUI-compliant): $600-$1,200 per window installed
- Impact-rated or tempered WUI replacement window: $1,000-$2,200 per window installed
- Entry door replacement (single door, no sidelights): $1,500-$3,500 installed
- Sliding patio door replacement (standard 6-foot opening): $2,500-$5,000 installed
- Custom window or door (odd size, specific finish): quote required after we measure
These are honest ranges, not teaser numbers. The final quote depends on the opening size, frame condition, and which manufacturer line fits your house. We quote manufacturer lines side by side on paper so you see exactly what you’re buying. Call (888) 635-0804 for a free estimate.

FAQs About Windows & Doors in Windsor
Yes. Windsor sits within Sonoma County’s High and Very High Fire Hazard Severity Zones, and after the 2019 Kincade Fire, the county ramped up enforcement of California’s Chapter 7A WUI standards. That means dual-pane tempered or multi-pane glazing, tight-fitting frames, and ember-resistant seals on any window or door replacement that pulls a permit. If your contractor doesn’t know the WUI checklist cold, you risk a failed inspection and a costly redo. Call (888) 635-0804 and we’ll walk you through what applies to your specific home.
Most standard WUI-compliant replacement windows in Windsor run $600 to $1,200 per window installed, with impact-rated units running higher depending on size and manufacturer. The fire-zone requirements add cost compared to a non-WUI town, but cutting corners here means failing inspection and paying twice. We give you written line-item quotes before any work starts so the number on the invoice matches the number you approved.
Yes. Any window or door replacement that changes the opening or triggers a Chapter 7A review requires a permit in Windsor, and we handle that process. We pull the permit, schedule the inspection, and make sure the job passes the first time. If a contractor tells you to skip the permit on a window swap, walk away.
Most single-story window replacements in Windsor wrap up in one to three days depending on how many openings we’re replacing and whether the old frames need repair. We schedule the work around the inspection window so you’re not left with open holes or a job half-finished. We’ll be there when we say.
Yes. TruePane offers a permanent 5% discount for seniors and veterans, plus a free written repair estimate. We also run a maintenance check for windows and doors that need adjustment but not full replacement. Call (888) 635-0804 and mention it when you schedule your estimate.
If you’re in Windsor and your windows are fogged, your sliding door drags, or you know the fire inspector won’t pass what’s on your house now, call TruePane Windows & Doors at (888) 635-0804. A live person answers, we measure every opening twice, and the quote you get is the price you pay.

What Windsor Customers Say
"Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A."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.
