Martinez’s Window & Door Crew

Martinez is the Contra Costa County seat, and its housing reflects that history: Victorian-era homes and early 1900s cottages downtown, bungalows and post-war homes across the hills, and rural properties in Alhambra Valley. Replacing windows in older homes takes care with original construction and plaster walls, and we bring that care to every job.

Replacing Windows in a Martinez Home

From the historic streets downtown to the open hillsides of Alhambra Valley, Martinez homes face different conditions. Here’s what shapes the right window choice.

Traditional home with new windows
Downtown

Older homes downtown

Martinez is the Contra Costa County seat and one of its oldest towns, and the streets around Main Street still have Victorians and early 1900s cottages with original wood windows. Replacement double-hungs in wood-look or fiberglass frames keep the narrow sight lines these houses were built with, so the front of the house still looks right while you gain dual-pane glass.

Narrow sight lines
Dual-pane glass
Plaster walls protected
Quiet living room with double-hung windows
Along the waterfront

Trains and highway noise

The Capitol Corridor and freight trains run along the waterfront, and Highway 4 and I-680 carry traffic around the city. Laminated glass, or dual-pane units with panes of different thickness, block noticeably more sound than standard dual-pane glass. We recommend it for the rooms where it matters, usually bedrooms facing the tracks or the road.

Laminated glass
Dissimilar-pane units
Quieter bedrooms
Sealed frames
Bright room with tall windows
Strait and valleys

Strait wind and summer heat

Homes near the Carquinez Strait take steady afternoon wind, while the valleys south of town get hot summer sun. Tight-sealing frames stop the drafts and whistling that worn windows let through, and Low-E glass keeps west-facing rooms cooler without darkening them.

No more whistling

City or county permit

Not every Martinez address is inside city limits. Parts of Alhambra Valley and Vine Hill are unincorporated, so permits go through Contra Costa County instead of the City of Martinez. Some hillside lots also fall in a state fire hazard zone, which calls for tempered glass. We check both before anything is ordered.

Hillside fire zones

Some hillside lots fall in state fire hazard zones that call for tempered glass. We check your address before ordering.

Painted-shut windows

Old wood windows painted shut or with soft sills are common here. We inspect and include any repair in the quote.

Martinez Window & Door FAQ

Quick answers to what we hear most. See our full FAQ →

Yes. We choose double-hung and casement styles, frame profiles, and grid patterns that match your home’s original windows, so the front of the house keeps its character. Bring photos of the originals or we’ll look at them during the estimate.
Laminated glass, or dual-pane units with two different glass thicknesses, reduce noise the most. Good installation matters just as much: gaps around the frame leak sound, so we seal and insulate every opening.
Many window replacements do, and all of them must meet California’s Title 24 energy standards. Inside city limits the permit comes from the City of Martinez; in unincorporated areas such as parts of Alhambra Valley and Vine Hill it comes from Contra Costa County. We check which applies to your address and handle the permit when one is required.
If your home is in a Very High Fire Hazard Severity Zone, California’s wildfire building standards call for dual-pane windows with at least one tempered pane. We check your address against the state fire hazard map during the estimate and spec the correct glass.
Yes, that’s common in Martinez’s older homes. We inspect every opening during the estimate, and if there’s rot that must be addressed before new windows go in, we tell you up front and include it in the written quote.
Never. Every installation is done by Alex and Leon’s own in-house crew, which is how we stand behind our 4-year workmanship warranty.
