Window Company in Whittier, CA
Juniper Windows & Doors is the window company Whittier homeowners call when they want a written price before any work starts, not after. We handle window replacement, window installation, and door replacement across Whittier, from the hillside homes off Painter Avenue to the classic ranchers near Whittier Boulevard. Replacements here run roughly $450 – $1,900 per window installed, and full door replacement typically lands between $1,400 and $4,800 depending on size, material, and whether we’re reworking the rough opening. Call (682) 281-2168 and we’ll give you a real number, on paper, before a single screw turns.
Why Whittier Homes Are Different
Whittier’s housing stock skews older than most of Los Angeles County, and that changes the way window and door work gets quoted. Much of the city was built between the 1920s and the 1960s, so we regularly open up walls and find non-standard rough openings, settled framing, and original wood sashes that have been painted shut for decades. None of that scares us, but it means a Whittier job is rarely a simple pull-and-swap. We measure twice before ordering because a half-inch difference on a 1940s Uptown bungalow means a custom order, not an off-the-shelf unit.
The terrain matters too. Whittier climbs from the flatlands near the 605 up into the Puente Hills, and homes up in the Friendly Hills and Spyglass Hill neighborhoods catch more afternoon sun and more wind than homes down near the Greenway. That’s why we talk about U-factor (how well the glass resists heat flow) and impact-rated options with hillside customers more than we do with folks down near Five Points. And Whittier has its own planning department, so if you’re in a historic district or an HOA-governed pocket, we’ll flag any approval step before you spend a dollar on glass.
Our Main Whittier Services
Most Whittier homeowners reach out for one of three jobs: replacing worn-out windows, installing windows in new construction or additions, or replacing a tired entry door. Each has its own dedicated Whittier page with pricing, timelines, and the exact process.
Window Replacement in Whittier
Replacing old single-pane wood windows in a Whittier home usually means a full tear-out: we remove the existing sash, frame, and trim, then set the new unit with fresh flashing and insulation. Many of the houses we work on in the Michigan Park and East Whittier areas still have their original 1950s aluminum sliders, which leak air and rattle with every passing truck on Whittier Boulevard. Our replacement crews fix the air leaks at the rough opening, not just the glass. See Window Replacement in Whittier for full pricing and timelines.

Window Installation in Whittier
New construction and addition work in Whittier moves on a different clock than replacement. If you’re adding a bedroom or building a garage conversion near Whittier College, we coordinate with your framing crew so the windows arrive when the rough openings are actually ready, not a week early. We install to the same written-price standard, and we’ll pull the measurements ourselves so the order comes in right the first time. Window Installation in Whittier covers the full installation process and what to expect on a new-build schedule.

Door Replacement in Whittier
Whittier homes from the 1930s and 1940s often have narrow door openings that don’t match modern pre-hung units. We rework the rough opening rather than forcing a door that binds every summer when humidity shifts. Front doors, back doors, French doors off a patio in the hills, and side doors that nobody remembers the key for: we quote them all with the same written price before the old door comes off. Door Replacement in Whittier lists door types, materials, and Whittier price ranges.

Two things push prices up in Whittier. Older rough openings that need reframing or leveling add labor, and homes in the hillside HOAs sometimes require specific window styles or colors that come at a premium. Whatever the job, the number we give you is the number you pay: written price, before anything starts, no change orders because we misjudged the opening. That’s the whole point of hiring us.

Yes. Hillside houses in Whittier have steeper access, more sun exposure, and more wind, so we spec impact-rated glass and tighter U-factors more often up there. The quote stays the same written-price process whether you’re on a flat lot or a ridge. Call (682) 281-2168 to set up a free estimate.
