Window Company in Fullerton, CA
Meridian Windows & Doors handles window replacement, window installation, and patio door installation across Fullerton, CA. Most homes here were built between the 1950s and 1980s, which means we spend a lot of time replacing original aluminum-frame windows that have warped, fogged, or stopped sealing. Fullerton’s inland heat and dry air put real stress on seals and frames, and we spec products accordingly. If you’re pricing a project, call (817) 686-2228 and we’ll give you a written number before any work starts.
Why Fullerton Homes Are Different
Fullerton sits about 25 miles inland from the coast, so summer temperatures routinely climb into the 90s while winter nights dip into the 40s. That swing matters for window selection. Low-E glass, which is a thin coating that reflects heat while letting light through, does real work here in July and August when west-facing bedrooms and living rooms catch the afternoon sun. We see a lot of original single-pane windows in the neighborhoods south of Commonwealth Avenue, in tracts built during the 1960s and 1970s, and those are the ones homeowners tell us turn rooms into ovens by 3 p.m.
Housing stock is a mix of mid-century ranch homes, Spanish-style builds from the 1920s and 1930s around the downtown core, and newer construction in the hills north of Bastanchury Road. The older homes often have non-standard rough openings, which means retrofitting matters more than a straight swap. Some neighborhoods fall under HOA oversight, particularly in newer developments, and we are familiar with what those boards typically require for visible window and patio door changes. Permits for window replacement in Fullerton are handled through the city’s building division, and we pull them when the job calls for it.
Our Main Fullerton Services
Window replacement and patio door installation are the two jobs Fullerton homeowners call us about most. Window installation work on new construction or additions is a close third. Each service has its own Fullerton page below.
Window Replacement in Fullerton
Most Fullerton replacement work involves pulling out failed aluminum or wood windows and setting new ones into existing openings. We measure every opening, check for dry rot in the surrounding framing, and quote the job with that condition built into the number. In Fullerton’s older ranch homes, we regularly find sill damage from years of irrigation overspray against exterior walls. That gets addressed before the new window goes in, not after. See Window Replacement in Fullerton for project details and local pricing.

Window Installation in Fullerton
New construction and room additions in Fullerton call for a different approach: rough openings are clean, flashing details get built from scratch, and the window is set before exterior finishes go on. We coordinate with framing and stucco crews, and we spec glass that meets California’s Title 24 energy requirements for new builds. Hillside lots north of Bastanchury Road commonly need custom sizing because the architecture is less uniform. See Window Installation in Fullerton for what the process involves.

Patio Door Installation in Fullerton
Fullerton backyards are built for indoor-outdoor living, and the patio door takes more daily use here than almost any other opening. We replace sliding doors, French doors, and a fair number of doors that have settled out of square in older slab foundations. Fullerton’s clay soil expands and contracts with moisture, which can shift door frames enough that a once-smooth slider starts sticking. See Patio Door Installation in Fullerton for product options and what a typical Fullerton job costs.
