AfterWindow Company in Berkeley, CA
Meridian Windows & Doors is a window and door contractor serving Berkeley, CA, with written pricing before any work starts and a 365-day guarantee on every installation. Berkeley’s housing stock, much of it built before 1980, combined with damp winters and steep hillside lots, means window and door work here rarely follows a simple template. If you need window replacement, window installation, or patio door installation in Berkeley, call (817) 686-2228 and we’ll put the price on paper before a single screw turns.
Why Berkeley Homes Are Different
Berkeley homes run the full range: Craftsman bungalows in the flats, split-levels and mid-century ranches in the hills, and a fair number of wood-framed structures that have settled unevenly over 70 to 100 years. That settling matters. A window opening in a 1920s Northbrae bungalow is rarely square, so installation here often involves extra shimming, reframing, and flashing work that a newer suburban tract home would not need.
The marine influence is real, too. Morning fog off the Bay keeps west-facing windows damp for months at a stretch, which is why we specify corrosion-resistant hardware and properly sloped sill pans on every Berkeley job. In the hills, homes above Grizzly Peak Boulevard get more wind and direct sun than houses down near San Pablo Avenue. The same window may need a different glass package depending on which side of the Berkeley Hills it faces. A meridian is a fixed line you measure everything against. That is what the name means, and how we run every install here.
Our Main Berkeley Services
Most Berkeley homeowners call us for one of two things: replacing windows that have rotted or lost their seal, or installing new windows and patio doors as part of a remodel. Each service has its own Berkeley page with local pricing and details.
Window Replacement in Berkeley
Older Berkeley windows often fail at the sashes and frames, not just the glass. Fogged double panes, wood rot in the lower rails, and counterweight systems that no longer hold are common across the flats and hills. We measure every opening before we order, account for the out-of-square framing, and install the replacement with new flashing and insulation. Learn more on our Window Replacement in Berkeley page.
Window Installation in Berkeley
New construction and additions in Berkeley bring their own requirements: title 24 energy compliance, egress sizing for bedrooms, and products that can handle the local climate. We install windows from eight manufacturer lines, so the product is spec’d for the opening and the exposure, not chosen because it was on a shelf. See Window Installation in Berkeley for what the process looks like.
Patio Door Installation in Berkeley
Berkeley’s indoor-outdoor living spaces, from flatland bungalows with rear garden access to hillside homes with deck-facing rooms, put a lot of use on patio doors. We install sliding and French patio doors with properly sealed thresholds, because a Berkeley winter will find any gap in a door sill within a season. Details are on our Patio Door Installation in Berkeley page.

What pushes a Berkeley price up is usually the house, not the product: out-of-square framing, lead paint remediation on pre-1978 homes, and second-story access on hillside lots all add labor. What doesn’t move the price is the estimate. You get a written number before work starts, and that number holds.
