Window Company in Upland, CA
We’re Meridian Windows & Doors, and we handle window replacement, window installation, and patio door installation for Upland homeowners. Most of the homes here were built between the 1950s and 1990s, so we see a lot of single-pane aluminum frames, wood rot around sills, and patio doors that have been sticking for years. Upland’s summer heat and those strong Santa Ana winds put real stress on seals and hardware. If you’re looking for a window company that writes the price down before any work starts, call us at (817) 686-2228.
Why Upland Homes Are Different
Upland sits right at the base of the San Gabriel Mountains, which means our crews work in real heat – regularly over 95°F from July through September – and on sloped lots where a bad measurement throws the whole install off. Homes in the older pockets north of Foothill Boulevard, especially around San Antonio Heights, were often built with different framing than the 1980s tracts south of the 210. That means we don’t carry one “standard” window into every job. We measure the actual opening, check whether the house has stucco or wood siding, and spec the frame accordingly.
Another thing we run into constantly: HOA rules. Upland has a few communities where window style and frame color are governed by association covenants. If you’re not sure whether yours is, we’ll help you check before you spend anything. The terrain also matters for patio doors – a lot of Upland backyards step up or down from the house, and a door that opens outward can hit a retaining wall if you don’t plan for the swing. These are the details we account for on day one, not the day of the install.
Our Main Upland Services
These three services account for nearly every call we take from Upland homeowners. Each one has its own dedicated page with pricing, timelines, and the specific conditions we handle in this city.
Window Replacement in Upland
When we replace windows in Upland, the typical job involves pulling out old aluminum or wood frames, repairing any rot in the surrounding framing, and setting new units with proper flashing and insulation. Older homes near Euclid Avenue and the historic districts often have unusual opening sizes, so we order to the eighth of an inch rather than forcing a stock size in. Low-E glass, which is a thin coating that reflects heat while letting light through, makes a meaningful difference in cooling costs here. Full details are on the Window Replacement in Upland page.

Window Installation in Upland
This service covers new-construction and addition scenarios: homes being remodeled, garage conversions, or ADUs going up in the back. Upland’s permitting office wants to see that windows meet Title 24 energy requirements, and we handle the documentation as part of the job. Because a lot of these projects are on hillsides north of Baseline, we also verify that the rough openings are square before any new window gets dropped in. See the Window Installation in Upland page for the full breakdown.

Patio Door Installation in Upland
Sliding glass doors, French doors, and multi-slide units – Upland homes have all three, and each one ages differently in this climate. The dry heat shrinks wood frames, and salt air isn’t a factor here the way it is at the coast, but UV exposure is relentless. We check the header above the door carefully; in 1970s-era ranch homes around Upland Hills we find undersized headers that need reinforcing before a heavier door goes in. Read the specifics on the Patio Door Installation in Upland page.

Upland prices shift based on the home’s age. Pre-1980s houses often need extra framing work or stucco patching once the old unit comes out, which adds a few hundred dollars per opening. Two-story homes and hillside lots can add equipment charges. Whatever the final number is, it goes in writing before any work starts, and it does not move at the door.
