Window Company in Gilroy, CA
Meridian Windows & Doors is the window company Gilroy homeowners call when a retrofit needs to be done right the first time. We replace windows, install new-construction windows, and set patio doors across Gilroy, and every job starts with a written price before any work begins. Most Gilroy homes were built between the 1960s and early 2000s, which means we see a lot of single-pane aluminum frames and original sliding doors that leak air and fight the afternoon heat. Call (817) 686-2228 to talk through the job, or keep reading to understand what makes Gilroy window work different from anywhere else in the South Bay.
Why Gilroy Homes Are Different
Gilroy sits at the southern end of Silicon Valley, where summer temperatures routinely push past 90°F and afternoon winds sweep down from the Gavilan foothills. That combination puts real stress on window seals, weatherstripping, and door thresholds. Homes in the older neighborhoods around downtown Gilroy and the Gilroy Gardens area often still carry original aluminum-frame windows from the 1960s and 1970s. Those frames conduct heat directly into the house and develop gaps at the sill that let dust from the garlic fields and surrounding agricultural land work its way inside.
Newer subdivisions east of Highway 101 and up toward Eagle Ridge were built with vinyl or builder-grade wood frames that are now hitting the 20 to 25 year mark. We regularly see failed insulated glass units in those areas, which show up as fog between the panes. Gilroy also has its share of stucco exteriors, which narrows the window opening and often requires a careful flange-and-trim approach so the new window seats correctly without cracking the surrounding finish. It is slower work, but it is the only way to keep the install clean and the waterproofing intact.
Our Main Gilroy Services

Start there, or call (817) 686-2228 with questions.
Window Replacement in Gilroy
Replacing an existing window in Gilroy usually means pulling the old sash and frame, correcting any rot or termite damage at the opening, and installing the new unit square to the opening. The biggest variable we see in Gilroy is the stucco exterior: many homes need the new window set as a retrofit, which keeps the exterior finish intact and keeps the price down. The heat here also makes low-E glass (a thin coating that reflects heat while letting light through) worth the small upcharge on any south- or west-facing wall. Full details and local pricing are on the Window Replacement in Gilroy page.

Window Installation in Gilroy
New-construction window installation in Gilroy applies when you are adding onto a home, converting a garage, or building a new structure on your property. The work is different from replacement because there is no old frame to work with, which means we are roughing the opening ourselves and setting the window with new flashing before the exterior finish goes on. Gilroy’s summer building season is dry and windy, so we pay close attention to flashing tape and sealing sequence on every new opening. That detail is what prevents leaks five years down the road. Read the full breakdown on the Window Installation in Gilroy page.

Patio Door Installation in Gilroy
Patio doors in Gilroy take a beating from sun exposure and gusty afternoon wind that rattles a poorly sealed threshold. We install sliding, French, and bi-fold patio doors, and in most Gilroy homes the job involves removing the old aluminum slider, checking the subfloor at the threshold for dry rot, and setting the new door on a flat base with new flashing. A door that does not close square will let dust and heat in every afternoon, which is why we level and shim the rough opening before we ever fasten the frame. Details and pricing on the Patio Door Installation in Gilroy page.

FAQs About Window Company in Gilroy
Yes. We handle stucco retrofits regularly, which means we set the new window from the inside and leave the exterior finish intact. For homes with moisture damage at the sill, we note it during the estimate and include the repair in the written price before work starts. Call (817) 686-2228 to schedule a free estimate.
Most Gilroy homeowners schedule their estimate about a week out, and we typically begin work within two to three weeks after the estimate is approved. Windows and doors with longer lead times, like custom PGT or CGI units, may add two to four weeks. Call (817) 686-2228 for current scheduling in your area.
For simple retrofit replacements that do not change the rough opening, Gilroy typically does not require a separate building permit, though we always comply with local code. For new-construction window installation, patio door rough openings, or work that alters the exterior envelope, we pull the permits and schedule the inspection. Call (817) 686-2228 and we will tell you what applies to your project.
