AfterWindow Company in Ontario, CA
Juniper Windows & Doors is the window and door company Ontario homeowners call when they want a written price before work begins, not after. We handle window replacement, window installation, and door replacement across Ontario, with crews dispatched from our Inland Empire office. Ontario’s mix of 1950s ranch homes, 1980s tract builds, and newer developments off Archibald and Vineyard means no two jobs look the same, and we price every one of them the same way: line by line, in writing, before a single screw turns. Call (682) 281-2168 to get your number.
Why Ontario Homes Are Different
Ontario sits in the heart of the Inland Empire, where summers routinely push past 100°F and the Santa Ana winds barrel through the Cajon Pass in fall. That means windows here take a beating from UV exposure, and doors face wind-driven dust and debris. Homes in older pockets like the areas around Euclid Avenue and Holt Boulevard often have single-pane aluminum windows original to the build, which leak conditioned air and rattle in the wind. Newer subdivisions east of the 15 and around Ontario Ranch have their own issues, mostly builder-grade vinyl that fades and warps within a decade. We also see a lot of patio doors with worn rollers and failing seals because Ontario backyards get used hard year-round. When we quote a job in Ontario, we quote for the climate: higher solar exposure, wind loads, and a housing stock that spans 70 years of construction methods.
Our Main Ontario Services
Most Ontario homeowners reach out to us for two things: swapping out failing windows, and replacing doors that no longer seal or slide. Each service has its own dedicated Ontario page below, with local pricing and specifics.
Window Replacement in Ontario
Window replacement in Ontario usually means pulling out old aluminum or builder-grade vinyl and installing something that can handle triple-digit summers without cooking the living room. We measure for U-factor and solar heat gain specific to your home’s sun exposure, because a west-facing window on a Park Grove home has a different job than a north-facing one off Vineyard. See full Ontario pricing and product options on our Window Replacement in Ontario page.
Window Installation in Ontario
Window installation covers new-construction and addition work, plus full-frame replacements where the old window comes out down to the studs. In Ontario, that often means matching stucco exteriors on mid-century homes near Chaffey High or working with new builds that still have builder wrap and flashing details. We document every opening with photos before and after. Get the full Ontario breakdown on our Window Installation in Ontario page.
Door Replacement in Ontario
Door replacement in Ontario covers front entry doors, patio sliders, and side doors that have warped, sagged, or lost their seal against Inland Empire heat and wind. Sliding glass doors take the worst abuse here, especially on homes with western exposure. We carry solid-core options and full slider replacements from the brands below. See what a new entry or patio door costs in Ontario on our Door Replacement in Ontario page.
