Window Company in Alhambra, CA
Juniper Windows & Doors is the Alhambra window company that puts a written price in your hand before any work begins. Alhambra’s mix of 1920s Spanish Colonials, mid-century ranches, and 1980s townhouses means no two window or door jobs are ever the same, so we quote every project line-by-line instead of guessing. If you’re looking for a window company that answers the phone, shows up when it says it will, and stands behind the work for a full year, call (682) 281-2168 for a free estimate.
Why Alhambra Homes Are Different
Alhambra sits in the western San Gabriel Valley, close enough to the hills that homes near Almansor Park and the north side get real afternoon heat while the flats stay mild. That puts genuine stress on window seals, wood frames, and door weatherstripping, and it’s why we pay attention to U-factor and solar heat gain when we spec glass here instead of just dropping in any replacement unit.
The housing stock is the bigger variable. Alhambra has block after block of pre-war bungalows with original wood sashes that have settled out of square, plus a large wave of post-war stucco homes where the original aluminum sliders have outlived their seals. Many of those older frames were never built for modern dual-pane glass, so installation often means reframing the rough opening rather than a simple swap. In the neighborhoods south of Main Street, we also see stucco homes where window openings were cut slightly oversized, which calls for a wider trim package to close the gaps cleanly. Every one of these conditions changes the price, the prep work, and the products we recommend.
Our Main Alhambra Services
Alhambra homeowners call us most often for two things: replacing failing windows and swapping out doors that let heat, noise, or water through. Here’s what each involves locally.
Window Replacement in Alhambra
Older Alhambra neighborhoods have a lot of single-pane wood windows that are drafty, fogged, or painted shut. We pull the entire old frame, address any rot or termite damage we find in the rough opening, and install a new unit sized to the actual opening rather than the old sash. Impact-rated glass is a popular upgrade in Alhambra for homes near busy streets like Valley Boulevard where road noise is constant. Every replacement carries a written price before we start, and the 365-Day Done Right Promise covers parts and labor on the completed install. More detail lives on our Window Replacement in Alhambra page.

Window Installation in Alhambra
When Alhambra homes get additions, ADUs, or new construction, someone has to lay out and set the windows correctly the first time. Our crews handle new-construction and retrofit installation, shimming and flashing each unit to keep water out of stucco and wood-framed walls alike. We work with contractors and homeowners directly, and we verify square before any window is fastened off. For more on how we handle installation projects, see Window Installation in Alhambra.

Door Replacement in Alhambra
Front doors in Alhambra take afternoon sun on the west side of the house, which warps cheap steel and fades finishes fast, and back doors get pushed into service as the main entry in many floor plans. We replace entry doors, patio sliders, and interior doors with units sized and sealed for Alhambra’s specific exposure patterns. Every door replacement starts with a written quote and ends with the same 365-Day Done Right Promise. Details and options are on the Door Replacement in Alhambra page.
