Window and door work in Lafayette follows a pattern we see on nearly every hillside street: original aluminum frames from the 1950s through 1980s, wide glass facing west, and seals that gave up years ago under Carquinez Strait winds and summer heat. Most Lafayette homes we visit need dual-pane, low-E replacements sized to custom openings, not stock units. We carry eight manufacturer brands so the recommendation fits the house, and every job starts with a written price before anything gets touched. Call (831) 480-4124 to schedule a free estimate.
Why Lafayette Homes Are Different
Lafayette’s housing stock runs heavily to custom ranch and split-level homes built on large lots between the 1950s and 1980s. That means wide expanses of glass, floor-to-ceiling window walls, and sliding doors oriented to capture hillside views. It also means custom-sized openings that do not accept off-the-shelf units, and decades of thermal expansion and contraction that have quietly destroyed seals and warped frames. The Mediterranean climate does the rest: hot, dry summers bake west-facing glass, while winter storms drive moisture into weathered openings. We regularly find aluminum frames that have lost their anodized coating and now corrode at the weep holes, leaving white oxidation streaks on stucco and fogging between panes.
Happy Valley and Burton Valley homes show this pattern consistently. Many were built with the same mid-century window packages, and many are now at the same failure point. Seismic movement adds another layer: Lafayette sits in an active fault zone, and original single-pane glass in shifting frames is a retrofit priority, not just an energy upgrade. The good news is that the opening sizes are usually generous, so a properly fitted dual-pane unit often makes an immediate difference in both comfort and noise from nearby Highway 24.
Styles & brands we work with
Our Main Lafayette Services
Two of the three services below cover what Lafayette homeowners call about most: replacing failed original windows and installing properly sized units in custom openings.
Window Replacement in Lafayette
Most replacement work in Lafayette involves removing original aluminum or single-pane wood windows and installing dual-pane, low-E units rated for the west-facing afternoon heat and winter wind-driven rain. We measure every opening on site because Lafayette’s custom ranch homes rarely have standard sizes. Corroded weep holes, fogged glass, and stuck sashes are the usual triggers, and we address the frame condition, not just the glass. Window Replacement in Lafayette
Window Installation in Lafayette
New-construction and addition work in Lafayette often means large fixed picture windows and sliding glass doors set into hillside-facing walls. The installation has to account for seismic movement, drainage at the sill, and thermal expansion in summer. We coordinate with your contractor or handle the full opening, and the written quote covers flashing, sealing, and interior trim so the price does not shift once work begins. Window Installation in Lafayette
Door Installation in Lafayette
Lafayette’s split-level and ranch homes often have original sliding patio doors that have become difficult to operate, or entry doors with warped frames from years of wet-winter exposure. Door installation here typically means leveling the rough opening, replacing rotted jambs, and hanging a properly sealed door that will not bind when the house moves. Door Installation in Lafayette

What Lafayette Customers Say
"Quiet, considerate install of several windows. They cleaned the glass and the sills and vacuumed every room. You'd never know a crew had been through. House is quieter and brighter."
- Brent Sakamoto"Lovely windows and a tidy install. One window came in a couple weeks late from the factory, so that opening finished after the others. They kept me posted and the rest was spotless."
- Mia Donnelly"Replaced six windows. The crew laid runners through the house and vacuumed each room as they finished. With a crawling baby, that no mess thing meant a lot. Windows are gorgeous."
- Rosalind Kemp
