AfterWindow Company in Belmont, CA
Meridian Windows & Doors handles window replacement, window installation, and patio door installation for homeowners throughout Belmont, CA. Most Belmont homes sit on hillside lots or in established neighborhoods where the marine layer, afternoon wind, and original 1950s-to-1970s construction all shape what a window or door actually needs to do. We spec products for those conditions, write the price down before work starts, and back every install with a written one-year guarantee. Call (817) 686-2228 to get your free estimate scheduled.
Why Belmont Homes Are Different
Belmont’s terrain is the first thing any installer notices. Streets climb away from El Camino Real toward the hills, and many homes are built on sloped lots with retaining walls, decks, and elevated foundations. That affects how a patio door is flashed, how a window is set, and how long a ladder run takes. The second thing is the climate: morning fog off the bay, afternoon sun on west-facing glass, and steady onshore wind through the Carlmont hills. Double-pane glass with low-E coating (a thin layer that reflects heat while letting light through) matters more here than inland, where the temperature swings are milder.
Housing stock also varies block to block. The flats around Ralston Avenue and Old County Road hold mostly mid-century ranchers and split-levels, while the hills up toward Hallmark Drive, Cipriani Boulevard, and Crestview Drive include larger custom homes with wide view-facing glass. Some neighborhoods fall under HOA review, and Belmont’s planning department requires permits for structural window work and any door opening that changes in size. We pull permits when the job calls for them and schedule inspections so the work closes out clean.
Our Main Belmont Services
Belmont homeowners call us most often for two things: replacing aging windows and putting in new patio doors. Each service has its own page with pricing, product options, and what to expect on the job.
Window Replacement in Belmont
Most replacement work in Belmont targets aluminum-frame windows from the 1960s and 1970s that have lost their seals or warped out of square. We replace them with new vinyl, aluminum, or wood-clad units sized to the existing opening, which keeps the stucco and trim intact. Hillside homes sometimes require scaffold or ladder work, and we account for that in the written estimate before any work begins. The 365-Day Done Right Promise covers the install for a full year. See the full breakdown on our Window Replacement in Belmont page.
Window Installation in Belmont
New-construction and addition window installation in Belmont usually means a rough opening is being framed, so the window gets nailed in, flashed, and sealed before trim and siding. We coordinate with the framing crew and install per manufacturer spec, then check the reveal, the level, and the caulk line. Belmont’s wind and morning damp make flashing the real point of failure, so we use the manufacturer’s tape and sealant system, not a generic substitute. Details and available product lines are on the Window Installation in Belmont page.
Patio Door Installation in Belmont
Sliding and French patio doors take a beating in Belmont, especially on hillside lots where wind hits the house from the west. We install doors from the brands we carry, set the threshold for drainage, and replace any rotted subfloor or jamb material found once the old door is out. The written estimate includes that contingency language so you aren’t surprised mid-job. A patio door is also the most common security weakness in a home, and we recommend multi-point locks on every unit we set. Product and price specifics are on the Patio Door Installation in Belmont page.

In Belmont, two things push a quote toward the upper end: hillside access that requires scaffold or extra crew time, and older homes where the rough opening has shifted out of square and needs reframing. Whatever the number, it goes on paper before work starts and it does not move at the door. If the install fails within 365 days, we return at no charge.
