Why Kentfield Homes Are Different
Kentfield splits into two distinct worlds. The valley floor along Woodland Road and Evergreen Avenue holds early-to-mid 20th century craftsman bungalows and colonial revival homes, many still running original wood-frame single-pane windows and solid-wood exterior doors. These units bleed heat, rattle in winter storms, and rot from the inside out where glazing putty has cracked.
The hillside parcels above College of Marin and Sir Francis Drake Boulevard sit in CAL FIRE Very High Fire Hazard Severity Zones. That means any window or door replacement must meet California Building Code Chapter 7A, enforced by Marin County’s Community Development Agency. Multi-pane tempered glass, non-combustible or ignition-resistant frames, and documented compliance paperwork are mandatory even on routine swaps. We’ve seen homeowners quoted standard vinyl jobs get stopped cold at permit review when the parcel map comes back red.
The Ross Valley’s topography funnels Pacific fog inland through gaps in the Marin hills, so Kentfield sees measurably higher humidity and rainfall than south-facing towns like Tiburon. North- and west-facing window sills and door jambs on older wood-frame homes show accelerated rot and failed glazing seals, typically needing attention every 10 to 15 years rather than the 20-plus you’d expect inland.
Our Main Kentfield Services
Most calls we get from Kentfield fall into three categories: swapping out failed units in older homes, installing new openings in additions or remodels, and upgrading hillside properties to fire-compliant assemblies.
Window Replacement in Kentfield
We remove the old unit, inspect the rough opening for rot or structural settling, and install a new assembly with proper flashing integration. On Kentfield’s valley-floor bungalows, we often find original wood sash weights still in the wall cavity and sills degraded from decades of fog exposure. We handle the Chapter 7A compliance paperwork for hillside jobs. Window Replacement in Kentfield covers full details on our process and what to expect.
Window Installation in Kentfield
New-construction and addition work in Kentfield means cutting openings into existing walls, running structural headers, and integrating with siding that may be 80 years old. Hillside estates frequently have custom rough openings that won’t accept standard units without field modification. We measure twice, fabricate or modify as needed, and seal everything to the weather barrier. See Window Installation in Kentfield for specifics on timelines and preparation.
Door Installation in Kentfield
Exterior door swaps in Kentfield range from standard pre-hung fiberglass units to custom fire-rated assemblies for hillside homes. We check the subfloor level, the hinge-side framing, and the threshold integration with existing decking or concrete. Many older Kentfield homes have settled slightly off-plumb, so we plane, shim, and seal until the door closes clean without binding. Details are at Door Installation in Kentfield.

What Kentfield Customers Say
"New patio slider. Clean install, they protected the floor and hauled off the old door. Quiet, polite crew that worked around my work calls without complaint."
- Andre Bellamy"They replaced a big foggy picture window. Careful with the furniture, laid down protection, and left no mess at all. Calm and respectful crew, and the view is clear again."
- Teresa Okafor"Replaced six windows. The crew laid runners through the house and vacuumed each room as they finished. With a crawling baby, that no mess thing meant a lot. Windows are gorgeous."
