AfterWindows & Doors Services in Kentfield, CA
If you live in Kentfield, you know the particular trouble this town gives a window frame. Mature redwoods and oaks throw shade across most lots, and that shade holds moisture against wood sashes and door bottoms for months at a time. We get calls from Kentfield homeowners whose windows look fine from the inside while the sill has already started to go soft underneath. TruePane Windows & Doors answers those calls from a live person, any hour, at (888) 635-0804. Crews serving Kentfield are dispatched from our San Francisco Bay Area office, and the technicians who show up know this town’s houses and the way its moisture works before they ever put a tape measure to an opening.
We’ve been doing windows and doors the same way since Dale Kessler founded this company: measure twice, quote on paper, register both warranty layers in writing before the truck leaves your driveway. That’s the Keystone Standard, and it’s on every job we do in Kentfield, from a single sash replacement to a full house of impact windows.

Why Kentfield Homeowners Choose TruePane Windows & Doors
Most of our Kentfield customers have lived in their homes for twenty years or more. They have replaced a water heater, maybe a roof, and at least one window that never quite closed right after the install. That last experience is usually why they call us. We’re not the cheapest bid in the room, and we will tell you that up front. What we are is the last call you need to make on a window or a door.
In the Kent Woodlands and up and down College Avenue, our background-checked, uniformed technicians show up when they say they will. They measure every opening twice. They quote manufacturer lines side by side on paper so you can see exactly what you are buying, whether that’s a Marvin wood double-hung to match a 1930s Colonial or a PGT impact-rated slider for a hillside view. Dale Kessler’s rule stays on the whiteboard: if the pane is not true, the job is not done.
Every job carries the Done Right Promise. If it is not done right, we make it right. No paperwork fights, no arguing. That promise, plus the Keystone Standard, is why Kentfield homeowners recommend us to neighbors on Sylvan Lane and Evergreen Drive.

Window Replacement
Rotted sills, fogged seals, and drafty sashes replaced with units sized and finished for your specific house. We check for wicking rot behind the sill pan before we quote, because in Kentfield the damage often starts where you can’t see it.

Impact Windows & Doors
Hillside streets in Kentfield fall within Marin County’s elevated wildfire exposure zones, and windborne ember protection matters. We install fire-rated glazing and impact-rated assemblies from manufacturers like PGT and CGI that meet the county’s Very High Fire Hazard Severity Zone standards.
Call (888) 635-0804 to schedule a free estimate for impact windows and doors in Kentfield.
Energy-Efficient Windows
Kentfield’s heavy canopy means less direct sun but more trapped moisture, so the right glass package and frame material matter more than a low-E sticker. We quote side by side so you see what you’re paying for.
Call (888) 635-0804 for an energy-efficiency assessment on your Kentfield home.
Sliding & Patio Doors
Sliders that bind in summer and leak in winter are common in Kentfield’s mid-century ranch homes. We replace tracks, rollers, panels, and full assemblies, then stand behind the work for 90 days with no arguing.
Call (888) 635-0804 to schedule a patio door quote in Kentfield.
Glass Railing Systems
Frameless and semi-frameless glass railings for decks and balconies on Kentfield’s hillside lots, engineered for Marin County code and installed with the same Keystone Standard as every window we set.
Call (888) 635-0804 to discuss glass railing options for your Kentfield property.
Custom Windows & Doors
Odd sizes, arch tops, true-divided lites, and historically sympathetic profiles for Kentfield’s older estates. If a stock unit won’t match your home’s original joinery, we’ll order one that will, from manufacturers including PGT, CGI, and ES Windows.

Why Kentfield’s Climate & Housing Affect Windows & Doors
Kentfield sits in a wooded Ross Valley pocket where mature redwood and oak canopy creates near-constant shade and drip-moisture on window frames and door thresholds. That sustained wet-dry cycling does more damage to paint films and joinery than outright rain exposure ever would. We regularly see windows in Kentfield’s 1920s to 1960s homes where rot has wicked up from the sill into the king studs before any failure is visible from inside. Redwood duff and leaf litter packs against the sill pan and holds moisture for months at a time. By the time a homeowner notices a sticking sash or a soft sill, the framing behind it may already need repair.
Because Kentfield is unincorporated Marin County, any replacement window or door project must satisfy the County’s design-review process. That often mandates historically sympathetic profiles and finishes, which makes a simple vinyl swap-out a non-starter for most properties here. We quote units that match the original character of Craftsman bungalows, Tudor and Colonial Revival estates, and mid-century ranch homes, and we handle the paperwork side of the county review so the homeowner doesn’t have to navigate it alone.

FAQs About Windows & Doors in Kentfield
Most Kentfield window replacements run $650 to $2,400 per window installed, depending on material, size, and whether the unit needs impact rating or historically sympathetic detailing. Rot repair behind the sill adds cost, and that is common in Kentfield’s shaded lots. Call (888) 635-0804 for an exact line-item quote, free of charge.
Yes. Because Kentfield is unincorporated Marin County, replacement windows and doors typically must satisfy the County’s design-review process, which often calls for historically sympathetic profiles and finishes on older homes. We prepare the documentation and quote units that meet those requirements. Call (888) 635-0804 to talk through your specific property.
Yes. We order true-divided and simulated-divided lite patterns from manufacturers including PGT, CGI, and ES Windows to match Craftsman, Tudor, and Colonial Revival originals found throughout Kentfield. Call (888) 635-0804 to get a match quote for your windows or doors.
No. Our quotes in Kentfield are fixed and line-itemed.

Most single-unit window replacements in Kentfield are completed in a single visit. Full door replacements and slider swaps usually take one day.

What Kentfield Customers Say
"Eleven windows replaced in two days. The crew chief, Marcus, showed me the level on every single frame before they caulked it. My wife noticed the street noise was gone before I did."
- Ronald P."A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G."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.
