AfterWindow Company in Moraga, CA
Most window and door projects in Moraga run $800 – $3,200 per opening depending on whether it’s a standard retrofit replacement or a new cut-in requiring structural modification and fire-rated framing. We’re Lightwell Windows & Doors, and we handle Moraga’s full range: replacing the original 1960s – 1980s aluminum single-pane units that now leak air and trap heat, installing new windows in additions or remodels, and upgrading exterior doors to meet Chapter 7A wildfire-urban interface standards. Every job starts with a written price before we touch anything. Call (562) 478-8017 to schedule your free estimate.
Why Moraga Homes Are Different
Moraga developed almost entirely between the late 1950s and mid-1980s as an affluent hillside suburb, producing a dense stock of single-story ranch and multi-level homes with wide eave overhangs, wood siding, and oversized fixed-glass picture windows oriented toward the surrounding ridgelines. Those original aluminum single-pane units are now 40 – 60 years old, with perimeter seals long since failed and frames that corrode in the valley’s seasonal moisture cycles.
The Moraga Valley acts as an inland heat trap: summer afternoons regularly reach 95 – 105°F while the coast 12 miles west sits at 70°F, creating extreme UV exposure and thermal cycling that degrades window sealants and vinyl frames faster than in most Bay Area communities. Fall Diablo wind events then drive low-humidity, high-velocity air through any gap in door weatherstripping, and those same offshore winds are the primary driver of the wildfire ember cast that makes fire-rated glazing a genuine local necessity rather than an upsell.
Here’s the code reality that surprises Moraga homeowners: the entire town sits within a CAL FIRE-designated Very High Fire Hazard Severity Zone. That means any window or exterior door replacement triggers Chapter 7A WUI review at the building department. The low-cost vinyl unit priced online is not permittable here. The job requires multi-pane tempered glass and a non-combustible frame, typically aluminum or fiberglass, a requirement that simply does not apply in the flatland Bay Area cities just 15 minutes away. We navigate this on every Moraga estimate so there are no permit surprises after work starts.
Our Main Moraga Services
Most calls from Moraga homeowners fall into three categories: replacing original windows that have failed after 40 – 60 years, installing windows in new openings or additions, and upgrading exterior doors for energy performance and fire compliance.
Window Replacement in Moraga
We remove the original aluminum single-pane picture windows, sliders, and awning units that dominate Moraga’s 1960s – 1980s housing stock, replacing them with Chapter 7A-compliant multi-pane tempered glass in non-combustible frames. We work around your schedule for kids’ nap times and use quiet tools where possible. Drop cloths protect floors and furniture, and we photograph the clean-up before we leave.

Window Installation in Moraga
New window openings in Moraga additions, ADUs, or remodels require structural headers, fire-rated framing, and Chapter 7A-compliant glazing from the start. We coordinate with your contractor or architect on rough opening specs, pull permits, and pass inspections. Our crews ask before moving anything, respect quiet hours, and explain every price before work begins. Window Installation in Moraga
Door Installation in Moraga
Exterior door upgrades in Moraga must meet the same WUI standards as windows: multi-pane tempered glass in sidelights and non-combustible frames. We install fiberglass and aluminum entry systems, French doors, and sliding patio doors that seal against Diablo wind infiltration while bringing daylight deep into the home. That’s the light well idea behind our name. Door Installation in Moraga
