Why Sebastopol Homeowners Choose TruePane Windows & Doors
Dale Kessler founded TruePane in 2008 on a rule that’s still written on the whiteboard in the shop: if the pane is not true, the job is not done. That rule governs every install our crew does in Sebastopol, whether it’s a full-frame replacement on a Craftsman bungalow near downtown or a sliding patio door in a ranch home out off Bodega Avenue. Homeowners in the Laurel Hill and Pleasant Hill neighborhoods have called us for years because we measure each opening twice, put manufacturer quotes side by side on paper, and register both warranty layers in writing before the truck leaves the driveway. That’s The Keystone Standard, and it’s the reason we can stand behind our work with a Done Right Promise: if it’s not done right, we make it right. No paperwork fights. No fine print that covers neither.
We’re not the cheapest bid in Sebastopol, and we don’t try to be. We’re the last call a homeowner needs to make on a window or door, backed by years of community service through the Kessler family’s glazing heritage. Our technicians are background-checked and uniformed, and they work in your home the way they’d work in their own mother’s. Every call is answered by a person, 24/7, because the homeowner who notices a fogged seal at 9 p.m. wants to talk to someone who can explain it, not leave a message and hope.
Windows & Doors Services We Offer in Sebastopol
Window Installation
We install new-construction and replacement windows in every housing style Sebastopol has, from late-Victorian frames near downtown to mid-century ranches on former orchard land. Every opening gets measured twice and flashed for Sonoma County’s wet winters, not a drier inland standard.
Learn more about our Window Installation in Sebastopol.
Door Installation
A new entry door in Sebastopol has to handle months of fog, rain, and wood movement that can throw an out-of-true frame out of square. We install exterior and interior doors with sill pans and thresholds rated for persistent moisture, so the door swings true in January and July alike.
Learn more about our Door Installation in Sebastopol.
Window Replacement
Most full-frame replacements we do in Sebastopol start with rot you can’t see until the old sash comes out: fogged seals, soft sills, and frames that have been wicking moisture for years. We replace the entire unit, not just the glass, and we quote manufacturer lines like PGT and ES Windows side by side so you know exactly what you’re buying.

Impact Windows & Doors
Impact-rated windows and doors aren’t just for hurricane zones; they add structural rigidity and noise reduction that Sonoma County homeowners appreciate when the coastal wind picks up. We’re an authorized installer for impact lines including PGT and CGI, and we handle the full permitting and inspection pass.
Energy-Efficient Windows
Sebastopol’s summer fog keeps afternoons cool, but winter heating bills climb fast in older homes with single-pane sash windows. We install low-E, argon-filled, and thermally broken units sized and spec’d for the 95472 climate, not a generic California average.
Sliding & Patio Doors
Sliding doors near the Laguna de Santa Rosa floodplain have to shed water differently than doors in the hills. We set tracks and rollers for the moisture load, and we replace threshold pans that have rotted from below, which is a failure we see regularly in the lower-lying parcels east and south of town.
Glass Railing Systems
Custom glass railing systems for decks and stairways give Sebastopol homes a clear sightline to the oaks and apple trees beyond without blocking light. We fabricate and install tempered and laminated panels to code, with hardware hidden or visible depending on the look you want.
Custom Windows & Doors
For a late-Victorian on Florence Avenue or a modern build off Petaluma Hill Road, custom sizes and shapes are often the only way to match original architecture or an unusual opening. We fabricate and install custom windows and doors to your measurements, using manufacturer lines we can warranty in writing.
Neighborhoods We Serve in Sebastopol
Our crews work throughout the 95472 ZIP, from the Craftsman-lined streets near downtown to the rural parcels on former Gravenstein orchard land. Typical response time for estimates in Sebastopol is within a few business days, and repairs or tune-ups can often be scheduled faster.

Why Sebastopol’s Climate & Housing Affect Windows & Doors
Sebastopol sits squarely in Sonoma County’s marine fog belt, receiving persistent coastal moisture funneled inland from Bodega Bay. That makes this city measurably damper than Santa Rosa just seven miles east or Petaluma to the south. The chronic moisture accelerates wood rot at window sills, door thresholds, and exterior frames at a rate that repeatedly surprises homeowners who moved here from drier Bay Area suburbs. Frame replacement and proper flashing are not occasional add-ons here; they are an expected part of almost every window and door job we do in Sebastopol.
The housing stock compounds the problem. The 95472 ZIP includes a core of late-Victorian and Craftsman bungalows from the 1900s through the 1930s near downtown, plus mid-century ranches and rural properties on old orchard land. The older wood-framed double-hung windows common to the Craftsman stock are especially vulnerable in this climate. Their glazing seals fail early under sustained condensation, and their wood sashes swell with the fall rains and stick or bind. Properties on the lower-lying parcels near the Laguna de Santa Rosa floodplain, particularly along the east and south edges of town, face another issue entirely: groundwater wicks up through subfloor framing and rots door thresholds and sill pans from below. A contractor used to working inland valleys will treat the visible exterior surface and miss that subsurface moisture source. We don’t, because we’ve seen it enough times to look for it every time.
Pricing for Windows & Doors in Sebastopol
Window and door pricing in Sebastopol depends on the unit, the manufacturer line, and the condition of the rough opening. A single retrofit window replacement typically runs $600 to $1,800 installed. Full-frame replacement, which most older Sebastopol homes need once rot is found, usually falls between $1,200 and $3,500 per opening. Entry door replacement ranges from $1,200 to $4,000 depending on material and hardware. Sliding patio doors start around $1,800 and can exceed $6,000 for premium impact-rated or custom units. Custom and impact work is quoted per job, always in writing, with both warranty layers registered before installation begins. Call (888) 635-0804 for a free estimate with no surprises on the bill.

FAQs About Windows & Doors in Sebastopol
A full-frame window replacement in Sebastopol typically costs between $1,200 and $3,500 per opening, with the higher end reflecting custom sizes, impact-rated glass, or extensive rot repair in the rough opening. Retrofit replacements run less, usually $600 to $1,800 installed. Call (888) 635-0804 for an exact quote; estimates are free.
Sebastopol’s marine fog and 35 to 40 inches of annual rain cause wood sashes and frames to absorb moisture and swell, which is why double-hung windows in older Craftsman and Victorian homes stick or bind every fall and winter. Full-frame replacement with properly flashed and sealed units is the permanent fix, not planing the sash, which only worsens the gap. Call (888) 635-0804 and we’ll assess what’s swelling and what’s worth saving.
Yes, when the rot is limited to the threshold or sill pan we can replace those components without pulling the entire door, but in Sebastopol we always check the subfloor beneath the threshold first. Properties near the Laguna de Santa Rosa floodplain often have moisture wicking up from below, and a threshold replacement alone will fail again if that source is not addressed. Call (888) 635-0804 for a free estimate.
Impact windows made by PGT or CGI add structural rigidity and meaningful noise reduction, which matters on Sebastopol’s windier western edges and along busier roads like Gravenstein Highway. They are not required by code here, but many homeowners choose them for the added strength and the insurance documentation that comes with a registered warranty. Call (888) 635-0804 and we’ll quote impact and non-impact lines side by side.
No. We quote in writing before any work begins, and what we quote is what you pay. If we open a wall and find rot that was not visible during the estimate, we stop and walk you through the options with a written change order you can approve or decline. There are no surprise line items on a TruePane bill. Call (888) 635-0804 to schedule your free estimate.

What Sebastopol Customers Say
"French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."
- Marie S."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.
