Windows and doors in Martinez face a specific set of conditions: strong Delta winds, steep diurnal temperature swings that make old wood frames swell and shrink, and housing stock that ranges from downtown Victorians to 1960s ranchers. Each of those homes needs a different approach. We’re Lightwell Windows & Doors, an independently operated Cedarwell company. We carry eight manufacturer brands, put every price in writing before work begins, and a live person answers the phone 24/7 at (831) 480-4124. A light well is what brings daylight deep into a building. That’s what a well-installed window should do for your home.
Why Martinez Homes Are Different
Downtown Martinez is full of Victorians and Craftsman homes over a century old, many still holding original wood windows with wavy glass. Those frames have been through 100 summers of hot, dry air and 100 winters of rain, and the repeated swelling and shrinking has taken a toll. A few miles out, the surrounding hills hold mid-century ranch and split-level homes built with aluminum frames and single-pane glass that fog, corrode, and leak heat. The common thread is the climate: Martinez gets real Delta breezes, and the temperature can drop 30 degrees from afternoon to night. That movement stresses seals and weatherstripping, which is why low-E glass and durable seals matter more here than in a milder microclimate. When we fit a window or exterior door in Martinez, we’re fitting it for the swings, not just the snapshot.
Styles & brands we work with
Our Main Martinez Services
Most Martinez homeowners reach out for one of two reasons: old windows that are failing against the climate, or doors that have warped, stuck, or stopped sealing. Each service has its own page with local detail, pricing, and what to expect.
Window Replacement in Martinez
Replacing windows in Martinez often means pulling out original double-hungs in a Victorian where the homeowner wants to keep the historic look, or swapping fogged aluminum sliders in a 1960s ranch for a vinyl retrofit that actually seals. We bring shoe covers and drop cloths inside, match the style to the era of the house, and put the full price in writing before the first pane comes out. Window Replacement in Martinez covers the full process and what it costs per opening.
Window Installation in Martinez
New construction, additions, or replacing windows in spaces that never had proper units before all fall under installation. In Martinez, the big variable is how the rough opening has shifted over decades of Delta wind and temperature swings. We square the opening, flash it for wet winters, and seal it so the afternoon heat stays outside. Window Installation in Martinez explains what goes into fitting a window that stays put.
Door Installation in Martinez
A door in Martinez does double duty: it keeps the heat out during a 95-degree afternoon and keeps the rain out in January. Older homes here often have beautiful wood doors with terrible sealing, while ranchers have hollow-core slabs that have warped over time. We install Therma-Tru and ViewLux entry and patio doors, adjusting for the settling every home does near the Delta. Door Installation in Martinez has the local specifics.

What pushes a Martinez price up is usually the age of the house. Century-old framing shifts, and restoring an original Victorian window takes more time than a clean retrofit on a 1960s ranch. Whatever the number, it’s written down before work starts and it does not change unless the scope changes, which we’ll tell you about first.

FAQs About Window Company in Martinez
Most like-for-like window replacements do not require a permit in Martinez, but changing the size of an opening or structural work on a load-bearing wall usually does. We can check the local requirements for your specific project and pull whatever permits are needed before work starts.
A straightforward window replacement on a standard home runs one to two days, depending on the number of openings and the condition of the surrounding framing. Historic homes downtown sometimes take longer because we’re preserving original trim and working around 100-year-old plaster.
We serve the full city, including the hillside areas, Alhambra Valley, and the surrounding unincorporated pockets. If you’re unsure whether your address is in our service area, call (831) 480-4124 and a real person will confirm it.
If your windows are drafty, your doors are sticking, or you’re ready to see what newer glass can do for a hot Martinez summer, call (831) 480-4124. We’ll measure, write the price down, and you decide. The estimate is free.

What Martinez Customers Say
"New patio slider. Clean install, they protected the floor and hauled off the old door. Quiet, polite crew that worked around my work calls without complaint."
- Andre Bellamy"Nice work and very clean. The only small thing was a bit of caulk smudge on one sill that I wiped off myself. The install itself was careful and the windows are excellent."
