Window Company in Tarzana, CA
Tarzana’s window and door work comes down to two forces: a brutal inland sun and a housing stock full of 1950s-to-1970s ranch homes with original aluminum frames. Those single-pane sliders were never built for the San Fernando Valley’s August heat or the Santa Ana winds that whip through the canyons each fall. Juniper Windows & Doors handles window replacement, window installation, and door replacement across Tarzana with one fixed rule: a written price before any work starts, backed by our 365-Day Done Right Promise. Call (831) 508-3441 and you’ll get a real person, 24/7, not a voicemail maze.
Why Tarzana Homes Are Different
Most of Tarzana was built out between the mid-1950s and late 1970s, and the dominant form is the single-story ranch: long, low rooflines, wide front elevations, and a lot of glass facing the street. The original windows on these homes are almost always single-pane aluminum sliders. Aluminum conducts heat, which means in July and August those frames get hot enough to burn a palm. The glass itself has no low-E coating, so afternoon sun pours straight through and the air conditioner runs harder than it should. Add a Santa Ana event with 50 mph gusts and you have warped tracks, rattling sashes, and seals that fail under dust and dry heat. Tarzana’s newer builds, especially the larger custom homes south of Ventura Boulevard, often feature floor-to-ceiling glass walls and oversized sliding door systems. Those look great until a seal fails and the glass fogs permanently, or a track shifts slightly out of level and the panel starts hanging up. North of the Boulevard you’re more likely to see traditional double-hungs in non-standard frame openings, which means custom sizing rather than off-the-shelf replacements. Permitting in Los Angeles for window and door retrofits is straightforward when the opening size doesn’t change, but any enlargement or structural header work triggers plan check. We walk every Tarzana job through that reality before we quote so the written price matches the job on permit day.
Our Main Tarzana Services
Tarzana homeowners call us most often for two things: replacing windows that have outlived the original build, and replacing doors that don’t seal or slide the way they used to. Here’s what each job involves in Tarzana, plus the dedicated page for details, local pricing, and FAQs.
Window Replacement in Tarzana
Most Tarzana replacement work starts with those original aluminum sliders. We pull the old frame completely, not just the sash, because the frame is usually the warped part. Then we install a new energy-rated unit sized to the opening, with low-E glass and a frame material that won’t flex in valley heat. South-facing glass takes the worst of it, so we often recommend a higher solar heat gain coefficient rating on those elevations. Learn more on the Window Replacement in Tarzana page, including a full price table by window style and glass option.

Window Installation in Tarzana
New-construction and addition work in Tarzana means different requirements: flashing details, square and level openings, and coordination with stucco or siding before the final trim goes on. We handle the full installation for builders and for homeowners adding onto an existing ranch, with attention to the header support older Tarzana framing sometimes lacks after decades of settling. The Window Installation in Tarzana page covers new-opening work, permit coordination, and what to expect on install day across one or two days.

Door Replacement in Tarzana
The sliding glass door at the back of a Tarzana ranch gets hammered by afternoon sun and occasional wind-driven dust. When the track binds or the rollers wear flat, replacement is often cheaper than a patch-and-repair cycle. We also replace front entry doors on mid-century homes where the original wood door has shrunk, warped, or lost its weatherstrip. The Door Replacement in Tarzana page has pricing for sliders, French doors, and entry doors, plus notes on security strike plates and fit-up tolerances for older jambs.
