AfterWindow Company in Kensington, CA
Windows and doors in Kensington take a beating from two directions: wet, salty air blowing off the Bay in summer and months of low winter sun that reveal every draft and failed seal. Homes here run older, with a lot of original 1940s and 1950s wood-framed windows that were built for a different climate. Meridian Windows & Doors handles replacement, installation, and patio door work across Kensington with written pricing before we start and a 365-day guarantee on every job. Call (817) 686-2228 to schedule a free estimate.
Why Kensington Homes Are Different
Kensington sits on the western slope of the Berkeley Hills, which means microclimates change block to block. Homes up near Colusa Circle and the Arlington side get more wind exposure and afternoon fog; the lower streets toward El Cerrito stay warmer and drier. That matters when you’re spec’ing low-E glass (a thin coating that reflects heat while letting light through) or deciding between double and triple glazing. A window that performs fine in the flats may fog or sweat on a hillside with constant marine air.
The housing stock itself runs heavily to 1930s through 1960s construction. We see a lot of original single-pane wood windows with failing putty, plus old aluminum sliders that have warped over decades of temperature swings. Terrain complicates the work, too: many Kensington homes sit on downslope lots with limited access to the rear of the house, which affects how we stage materials and where a ladder can safely go. We plan for that before the crew arrives, not on the fly.
Our Main Kensington Services
Most Kensington calls to us fall into two buckets: replacing windows that have reached the end of their life, and installing new windows or patio doors during a remodel or addition. Here is what each involves in Kensington.
Window Replacement in Kensington
Replacement work here usually means pulling out original wood-framed windows that have rotted sills or sashes that no longer seal. Hillside moisture is the usual culprit, especially on north-facing walls that never fully dry out. We measure every opening, order the replacement to spec, and handle lead-safe removal on older homes. Written pricing comes before any work starts. Window Replacement in Kensington
Window Installation in Kensington
New-install work means open framing, typically during an addition, a gut remodel, or when a homeowner is converting an enclosed porch into living space. Kensington setbacks and slope constraints mean permits are often required, and we work with that process directly. The install is flashed and sealed for a hillside climate, not a flat suburban lot.

Patio Door Installation in Kensington
Patio doors here have to handle wind-driven rain off the Bay and hold a consistent seal through fog cycles that swell and shrink the surrounding framing. We install sliding and French doors from Therma-Tru and others, with the rough opening squared and shimmed for a hillside house that has settled. If the old door was never flashed properly, we fix that during the install. Patio Door Installation in Kensington
