Window Company in Kentfield, CA
Window company work in Kentfield, CA comes down to three things: older homes with original framing that has settled, strong seasonal temperature swings between foggy mornings and dry inland heat, and a hillside terrain that exposes windows and doors to more wind and sun than the flatlands a few miles east. Meridian Windows & Doors replaces, installs, and upgrades windows and patio doors across Kentfield with written pricing before any work starts and a 365-day guarantee on every job.

Why Kentfield Homes Are Different
Homes in Kentfield sit against the base of Mount Tamalpais, and most were built between the 1940s and 1970s. That means single-pane windows, aluminum frames, and wood sills that have absorbed fifty or sixty years of coastal fog. We see the same pattern on nearly every street: frames that have swelled and stuck, glass that fogs between panes, and patio doors that no longer glide. The moisture here is the quiet enemy. Fog rolls over the ridge at night, sits on the west-facing elevations, and works its way into caulk joints and weep holes. Homes at higher elevations in Kentfield get more of it than those closer to College Avenue, so the condition of exposed window frames varies block by block.
Marin County also enforces stricter energy codes than most of California’s Central Valley. When we pull a permit for window replacement in Kentfield, we build to Title 24 standards, which often means low-E glass (a thin coating that reflects heat while letting light through) and dual-pane assemblies specified for the home’s exact orientation. HOA requirements in some Kentfield neighborhoods also dictate exterior finish colors and frame materials, which is why our written quote always notes the finish type before you sign anything.
Our Main Kentfield Services
Kentfield homeowners call about two things most often: replacing windows that have failed after decades of coastal exposure, and installing new windows or patio doors during additions and remodels. Here is what each job involves here.
Window Replacement in Kentfield
Most Kentfield replacement jobs start with a failing wood or aluminum frame, not a broken pane. We remove the old unit down to the rough opening, inspect the sill and flashing for moisture damage, then install a new window sized properly for the existing opening. On a 1960s hillside house, it is common to find the rough opening has shifted a quarter inch or more, which is why we measure every opening individually and never order a single batch size for the whole house. Window Replacement in Kentfield is covered on its own page, including what fails first and how long the job takes.

Window Installation in Kentfield
When a Kentfield homeowner builds an addition or opens a wall, new window installation is a different job from replacement. There is no old frame to remove; instead, we set the new unit into fresh framing, flash it properly for Marin County’s wet seasons, and make sure water drains away from the sill, not toward it. Building inspectors here look hard at flashing details on hillside lots where wind-driven rain hits windows at an angle. Window Installation in Kentfield details what we do at each step, from rough opening to final trim.

Patio Door Installation in Kentfield
Sliding and French patio doors in Kentfield take a beating from fog, sun, and uneven settling. A door that was square in 1980 may now be off by three-eighths of an inch at the top corner. Patio door installation here starts with checking the opening, correcting any sag in the header, and setting the new door on a level sill with proper weatherproofing. We install doors that will still glide ten years from now, and we back that in writing. Patio Door Installation in Kentfield covers sizing, materials, and what a typical Kentfield install involves.

FAQs About Window Company in Kentfield
Yes. Kentfield falls under Marin County building jurisdiction, and window replacement that changes the opening size or moves a frame requires a permit. We pull the permit, schedule the inspection, and make sure the installation passes before we call the job done. The permit fee is itemized on your written quote, not added as a surprise later.
Our Bay Area dispatch coordinates Kentfield crews locally, so most estimates are scheduled within a few business days and small repairs often fit into an existing route sooner. The fastest way to get a specific date is to call (817) 686-2228 and talk to a live person, not a voicemail.
We do, and a large share of our Kentfield work is on homes built before 1980 with original wood windows. We measure every opening individually because settled framing means no two openings are identical, even on the same wall. The quote you get reflects the actual condition of each opening, not a generic per-window price.
