AfterWindow Company in Fairfax, CA
Juniper Windows & Doors handles window replacement, window installation, and door replacement for homes across Fairfax, CA. Most Fairfax work involves two realities: older hillside homes with odd rough openings, and a climate that swings from damp, foggy winters to dry, hot summer stretches. If you’re comparing window companies in Fairfax, the first thing to know is that we write the price down before any work starts. No door-to-door adjustment, no surprise line item at the end. Call (682) 281-2168 and you’ll get a real person, not a voicemail tree.
Why Fairfax Homes Are Different
Fairfax is not a tract-home town. Much of the housing stock was built between the 1920s and the 1970s, and a lot of it climbs the hills around Cascade Canyon, Deer Park, and the slopes above downtown. That means we regularly see narrow lot access, hillside foundations, and rough openings that are anything but square. A stock window from a big-box shelf often doesn’t fit without modification, so we measure every opening and spec the frame depth, sill angle, and reveal before ordering anything.
The microclimate matters too. Homes on the north side of town and along the creek corridors stay damp much of the year, which accelerates wood rot around old window sashes and door jambs. Homes higher up and facing south get intense UV exposure, which fades and degrades vinyl and old builder-grade glazing faster than homeowners expect. We account for both when we recommend frame materials and glass packages. And because Fairfax sits in Marin County’s WUI zones in many areas, impact-rated glass and defensible-space-aware door sealing come up more often here than in most Bay Area towns.
Our Main Fairfax Services
Most Fairfax homeowners reach out to us for one of two things: replacing windows that have failed, or planning new window and door work on a remodel. Here’s what each looks like in Fairfax.
Window Replacement in Fairfax
Replacement work in Fairfax usually means pulling out sash kits or full frames that have warped, rotted, or lost their seal. We often see fogged double-pane units from the early 2000s on the south-facing elevations, while north-facing openings have rot in the sill from years of winter moisture. We measure each opening individually, because Fairfax’s older homes rarely have two identical windows. Then we spec a replacement that matches the existing sightlines and works with the home’s trim. Window Replacement in Fairfax covers the full process, including typical costs and timeline.
Window Installation in Fairfax
New construction and addition work in Fairfax calls for a different approach. The rough openings are exposed, so we can install flanged windows with proper flashing and air-sealing from the start. Fairfax’s hillside builds and additions often need custom sizes and upgraded U-factors to pass Marin’s energy requirements. We coordinate with the framing crew, set the windows, and document the flashing before the siding goes on. Window Installation in Fairfax has the full breakdown for new-build and remodel projects.
Door Replacement in Fairfax
Front doors in Fairfax take a beating from late-afternoon sun on west-facing entries and damp air that swells wood jambs. We replace entry doors, patio sliders, and French doors, and we re-frame the rough opening when the surrounding structure has rotted. For homes in Fairfax’s steeper lots, a properly sealed and aligned door also keeps cold air from pouring in at night. Door Replacement in Fairfax details what a replacement entails and what homeowners typically spend.

Brands We Service in Fairfax
We work with our brands including PGT, CGI, CWS, and ES Windows. That matters in Fairfax because hillside homes and WUI-adjacent lots often need impact-rated or high-performance glazing that generic supply houses don’t stock. We order directly and coordinate the lead time so materials arrive before the install crew does.

In most Fairfax cases, replacing an existing window or door with a similar-sized unit doesn’t require a permit. Structural changes, new rough openings, or work in certain WUI or historic areas can trigger Marin County requirements. We’ll walk you through what applies before we write the estimate, so the price reflects any permit work from the start.
Yes. Fairfax has a lot of period homes with divided lites, wood trim, and unusual proportions. We can match the sightline, grid pattern, and frame color closely enough that neighbors won’t spot the difference. We’ll photograph and measure the existing windows during the estimate so the replacement doesn’t look like a patch job.
Yes. We coordinate the crew schedule, bring the materials, and handle removal of the old windows and doors. The install crew cleans the work area before they leave, and you get before-and-after photos so you can see what was done even if you weren’t home during the install. The written price covers all of that.
