Window Company in Simi Valley, CA
Juniper Windows & Doors is the window company Simi Valley homeowners call when original aluminum frames start rattling in a Santa Ana wind or a sliding door stops rolling on its track. Most of the homes here went up between the 1960s and 1980s, and the original single-pane windows that came with them are now fifty-plus years old. We replace and install windows and doors across Simi Valley, and every job gets a written price before work begins. Call (559) 314-1305 for a free estimate.
Why Simi Valley Homes Are Different
Simi Valley’s housing stock has a very specific fingerprint. The east side is full of tract homes built in the 1960s and 1970s, and a surprising number still have their original single-pane aluminum windows. Those frames conduct heat straight into the house during July and August, and they rattle audibly when the Santa Ana winds push through the valley from the northeast.
The dry, dusty conditions here also take a toll on moving parts. Sliding glass door rollers gum up with grit, aluminum tracks wear down, and weatherstripping dries out and cracks. We see homes near the foothills in Wood Ranch where gusts whistle through old window seals, and homeowners notice it most on windy afternoons. Dual-pane glass with low-E coatings isn’t a luxury in Simi Valley; it’s the difference between a room that holds temperature and one that bakes by 3 p.m. Winter nights dip near freezing in the valley floor, so insulation matters on both ends of the thermometer.
Our Main Simi Valley Services
These are the three jobs Simi Valley homeowners call us about most, and each has its own page with full pricing and local details.
Window Replacement in Simi Valley
Replacing original aluminum windows in a 1970s Simi Valley tract home means pulling frames that were never designed for today’s energy codes. We measure for tight fits, address any dry rot at the rough opening, and install dual-pane units with low-E coatings that actually block the valley’s solar heat. Many east-side homes benefit from going to impact-rated glass, since wind-borne debris during Santa Ana events is a real concern near the foothills. Window Replacement in Simi Valley.
Window Installation in Simi Valley
New construction and addition work in Simi Valley follows Ventura County building codes, and we handle the paperwork alongside the install. The dry climate means we pay close attention to flashing and sealant details, because dust intrusion through a poorly sealed rough opening shows up fast. We install PGT, CGI, CWS, ES Windows, ECO Window Systems, and Mr-Glass products, and every install gets a written price before the first screw turns. Window Installation in Simi Valley.
Door Replacement in Simi Valley
Original sliding glass doors in Simi Valley homes are often as old as the windows, with worn rollers and bent tracks. We replace them with modern units that seal tight against dust and wind, and we also handle front entry doors where homeowners want better security and insulation. Therma-Tru and ViewLux doors are popular choices here for their durability in dry heat. Door Replacement in Simi Valley.
