Window Company in Covina, CA
Juniper Windows & Doors is the window company Covina homeowners call when they want a written price before work begins, not after. Covina’s mix of 1950s ranch homes, hillside properties north of the 210, and newer builds near Charter Oak each present different window and door challenges. Sun exposure on south-facing walls fades old vinyl and warps builder-grade frames. Older wood sash windows swell in winter and stick. We handle all of it, and every job starts the same way: a real person answers the phone at (682) 281-2168, and you get a locked number in writing before a single screw turns.
Why Covina Homes Are Different
Covina sits right where the San Gabriel Valley starts to roll into foothills, and that geography shows up in the work. Homes south of Badillo Street sit on flatter lots and tend to be mid-century builds with original single-pane windows. North of Covina Hills Road, the elevation changes and the wind picks up, which means exterior doors take more weather and windows need hardware that won’t sag under repeated thermal cycles. Summer heat regularly climbs past 95°F, so U-factor matters here more than a homeowner might think. A low U-factor means less heat transfer through the glass, and in Covina that translates to a cooler living room in August and a lower AC bill. We also see plenty of homes in the Covina Hills area where HOA design guidelines dictate window frame colors and door styles, so we help homeowners navigate that paperwork before ordering anything.
One more thing about Covina: many homes built before 1978 have original aluminum-frame windows. Those frames conduct heat efficiently, which is the wrong direction for a city that gets this much sun. Replacing them usually requires careful flashing work around stucco exteriors, and that’s where experience with Covina’s specific housing stock prevents leaks down the road.
Our Main Covina Services
These are the two jobs Covina homeowners ask us about most. Each has its own page with pricing, timelines, and answers to the questions we hear on almost every call.
Window Replacement in Covina
Window replacement in Covina usually means pulling out old aluminum or wood sashes and fitting new frames into existing openings. The biggest variable is what’s behind the stucco: some Covina homes have drywall returns that make a retrofit straightforward, while others have plaster that requires a full-frame replacement. We measure every opening twice, order exactly to spec, and install with new flashing and insulation. No surprises at the end because the price is fixed before we order. Window Replacement in Covina covers the full process and typical costs.

Window Installation in Covina
New window installation in Covina comes up most often with additions, garage conversions, and homes where the original framing needs reframing for larger glass. Hillside lots in Covina Hills sometimes need engineering review when enlarging openings on load-bearing walls, and we coordinate that. This is different from replacement; installation means the opening itself is new or resized. We bring the same fixed-price approach, and the work still falls under the 365-Day Done Right Promise. Window Installation in Covina has the details.

Door Replacement in Covina
Door replacement in Covina gets called in for three reasons: a warped front door that no longer seals, a patio slider with fogged glass, or a security upgrade after a break-in attempt. Front doors on west-facing Covina entries take brutal afternoon sun, which is why we recommend fiberglass or properly finished wood over thin steel. Sliders are a big one too; many Covina homes have original aluminum sliders from the 1970s that rattle in the wind and leak air at the track. Door Replacement in Covina walks through options and what each costs.
