AfterWindow Company in Lafayette, CA
Meridian Windows & Doors is a window and door company serving Lafayette, CA with replacement, installation, and patio door work. Most Lafayette homes sit in the hills where afternoon sun hits west-facing glass hard, and many of those homes were built between the 1950s and 1980s, so we see a lot of single-pane aluminum frames that are long past their useful life. The price for most single-window replacements here runs $600 to $1,800 installed, depending on the material and opening size. Call (817) 686-2228 for a written quote before any work starts.
Why Lafayette Homes Are Different
Lafayette sits on the east side of the Oakland Hills, which means temperature swings that move more than people expect. Mornings can be cool and fog-influenced, afternoons dry and hot, and north-facing elevations stay shaded for months. That combination pushes homeowners toward low-E glass (a thin coating that reflects heat while letting light through) and frames that will not warp when the dry season hits. We also see houses on sloped lots where drainage moves toward the foundation, and a window opening that leaked for a decade often shows itself the first winter after a big rain.
Parts of town like Happy Valley, Burton Valley, and Reliez Valley each have their own rhythm. Happy Valley gets strong evening sun on rear elevations. Burton Valley has a high concentration of ranch-style homes where original wood sashes are still in place. Reliez Valley has larger lots and more custom builds, which means odd opening sizes that call for a measured replacement rather than a stock unit. Lafayette also has an active design review process in some areas, so we keep our paperwork tight and our crews familiar with what the town expects on the day of install.
Our Main Lafayette Services
Lafayette homeowners typically call us for two things: replacing old windows that no longer seal or operate, and putting in new door units that hold up to the hillside weather. Each service has its own dedicated Lafayette page below.
Window Replacement in Lafayette
Replacement work here usually means pulling a worn aluminum or wood unit out and setting a properly flashed new one in the same opening. In Lafayette, the condition of the original rough opening matters more than most people think; older hillside homes can have dry rot or settling around the sill that only shows once the old frame comes out. We measure every opening, write the product and labor price down before work begins, and cover the install under our 365-Day Done Right Promise. Window Replacement in Lafayette.
Window Installation in Lafayette
New construction and addition work in Lafayette means installation into a clean rough opening, with flashing and leveling done from the start. Homes on sloped lots in areas like Burton Valley often have non-standard framing, so we take field measurements and spec the window to the actual opening, not the original plan. The damp winter months here mean proper flashing is the difference between a dry wall and a callback. Window Installation in Lafayette.
Patio Door Installation in Lafayette
Lafayette backs up to open space and ridge lines, so patio doors are not just an aesthetic choice; they get worked hard by wind, sun, and the occasional critter looking for a gap. We install sliding and swing patio doors that close tight and latch cleanly, with thresholds set for the slope of the deck or pad outside. If the existing door has sagged or the track is shot, the full replacement conversation starts with a written quote. Patio Door Installation in Lafayette.
