AfterWindow Company in Martinez, CA
Window and door work in Martinez means dealing with an older, character-rich housing stock, hot inland summers, and a marine layer that rolls in off the Carquinez Strait most evenings. The houses here were built for a different climate than the one we live in now, and a lot of the original single-pane windows and wood-framed patio doors are simply at the end of their useful life. Meridian Windows & Doors handles window replacement, window installation, and patio door installation throughout Martinez, with a written price before the first screw turns and a 365-day guarantee on the work. Call (817) 686-2228 when you want an estimate that will not change at the door.
Why Martinez Homes Are Different
Martinez has a distinct housing profile. A large share of the homes were built between the 1920s and 1970s, with original single-pane windows, dry-rotted wood sills, and door openings cut to old framing conventions. The hillside pockets up near Hidden Lakes and the Vine Hill area add real variables: sun exposure that bakes west-facing panes, wind that finds every gap in a wood frame, and soil movement that can throw a patio door off its track over time. Downtown and the older grid streets around Alhambra Avenue carry the typical Martinez story: houses with charm and history, and windows that no longer open, seal, or lock the way they should.
The climate is the other driver. Summer highs regularly push into the 90s, and homes without modern low-E glass absorb that heat and hold it all night. When the delta breeze picks up, air pressure differences make drafty windows and doors obvious. We spec glass for this specific environment: low-E coatings that reflect heat while letting light through, frames that hold their seal against salt air from the Strait, and patio doors rated for wind exposure. This is not stock product pulled off a shelf; it is the right product for how a Martinez house actually sits on its lot.
Our Main Martinez Services
The two calls we get most from Martinez homeowners are for full window replacement and for patio door installation. Each has its own detailed page below, with local pricing and what the work involves on a Martinez house.
Window Replacement in Martinez
Replacing windows in Martinez usually means pulling out original single-pane sashes and reframing the opening for a modern, energy-efficient unit. Older homes here often have non-standard rough openings, so we measure each one and order to the actual dimensions rather than forcing a stock size and covering the gap with trim. The delta breeze and hot summer sun are the two forces we build against. Window Replacement in Martinez has the full scope and local price ranges.
Window Installation in Martinez
Window installation for new construction and additions in Martinez follows a different set of rules than replacement work. It requires coordinating with the framing stage, flashing the opening properly before the exterior finish goes on, and meeting Contra Costa County and city building code at every step. We work with builders and homeowners who are adding rooms, converting garages, or building new homes in the hills and downtown. Window Installation in Martinez covers what that process looks like from rough opening to final inspection.
Patio Door Installation in Martinez
Patio doors in Martinez take a beating. Older sliders here are often aluminum-framed, heavy, and long past their sealing life. We install modern sliding and French doors that open smoothly, seal tight against the evening wind, and hold up to the sun exposure that cooks west-facing back doors all summer. If your current door sticks, drags, or lets air through when the delta breeze kicks up, Patio Door Installation in Martinez walks through the options and what installation costs here.

Pricing for Window Company in Martinez, CA
Here are the price ranges we typically see for window and door work in Martinez. These are installed figures for standard projects on most Martinez homes; odd rough openings, custom sizing, and higher-end glass packages move the number up.
| Service | Typical range in Martinez |
|---|---|
| Single window replacement (standard size) | $600 – $1,200 installed |
| Full-home window replacement (8 – 12 windows) | $8,000 – $18,000 installed |
| Window installation (new construction, per opening) | $500 – $1,100 installed |
| Patio door replacement (sliding, standard 6 ft.) | $1,800 – $3,500 installed |
| Patio door installation (French, standard 6 ft.) | $2,200 – $4,200 installed |
| Low-E glass upgrade (per window, added to replacement) | $150 – $400 added per window |
| Wood sill repair (per sill, before or during window work) | $150 – $450 per sill |
| Full frame window replacement (per window, rot or reframe) | $900 – $1,700 installed |
What pushes the price up in Martinez is what you would expect: original rough openings cut to odd dimensions, dry rot behind the siding, and the hillside access that makes staging and hauling harder. It is also getting pricier to do custom glass work, so a picture window with specific sightline requirements will land above the standard range. Every Meridian Windows & Doors quote is written down and delivered before any work starts, and that number does not move at the door.
