AfterWindow Company in Danville, CA
Juniper Windows & Doors handles window replacement, window installation, and door replacement in Danville, CA. Most of the homes we work on here were built between the 1960s and early 2000s, which means we see a lot of aging aluminum frames, single-pane glass, and doors that have warped after decades of East Bay sun. Danville’s mix of sprawling ranchers, two-story traditional homes, and newer custom builds means no two jobs look the same. Call (682) 281-2168 and we’ll give you a written price before anything starts.
Why Danville Homes Are Different
Danville sits in the San Ramon Valley, tucked between the Las Trampas foothills and Mount Diablo. That geography creates a few realities for windows and doors. Summer temperatures routinely climb into the 90s, and the afternoon sun hits western-facing exposures hard. Homes on the west side of Danville, especially in neighborhoods like Westside Danville and Greenbrook, often see the most glass fading and frame expansion. We spec low U-factor glass for those elevations, because that’s the number that tells you how well a window resists heat transfer.
The other big factor is housing stock. Danville has hundreds of homes from the 1960s and 1970s, many with original single-pane windows and sliding patio doors that let conditioned air leak out year-round. The town also has a growing number of whole-home renovations in areas like Magee Ranch and Blackhawk, where homeowners want sightlines that preserve hill views while cutting energy loss. That’s where impact-rated glass and narrow-frame products from manufacturers like CGI and ES Windows come in. We also know that some Danville neighborhoods have HOA architectural reviews, so we’ll tell you up front if a door color or window style change needs committee approval before we order anything.
Our Main Danville Services
Danville homeowners call us most about replacing old windows and swapping out tired entry or patio doors. Each service has its own page with local pricing, timelines, and what to expect.
Window Replacement in Danville
Window replacement here usually means pulling out aluminum single-pane frames from the 1970s and putting in dual-pane, low-E glass that actually holds temperature. We measure every opening, check for dry rot in the existing frame, and write a price that covers the full job, including trim and haul-away. Danville’s afternoon heat makes glass selection matter more than most people expect. See the full breakdown on our Window Replacement in Danville page.
Window Installation in Danville
New construction and additions in Danville need windows installed before drywall goes up, which changes the flashing and waterproofing details. We handle window installation for additions, ADUs, and full tear-downs, and we coordinate with your general contractor so the schedule doesn’t stall. Danville’s hilly lots in neighborhoods like Crow Canyon and Diablo Highlands sometimes mean second-story windows need different access equipment, and we plan for that before the crew shows up. Details are on the Window Installation in Danville page.
Door Replacement in Danville
Entry doors in Danville take a beating from summer heat, which warps wood and loosens hinges over time. We replace front doors, French doors, and sliding patio doors, and we carry Therma-Tru and ViewLux lines that hold up better in sustained sun than standard builder-grade doors. If your door faces west or southwest, we’ll recommend a product that won’t expand and stick in August. Pricing and timelines are on our Door Replacement in Danville page.
