Alamo homes sit on big lots, from classic ranch houses to custom estates in Round Hill and the hills off Stone Valley Road. We replace windows and doors across Alamo with premium options where they make sense, and we handle the county permit and any HOA review.
No subcontractors, ever. You deal directly with Alex and Leon Elbert, the brothers who own the company and show up on your job.
Get My Free QuoteAlamo is unincorporated, so it has no city hall of its own: permits go through Contra Costa County. Homes range from 1950s and 60s ranch houses on large lots to custom estates and gated communities like Round Hill. Many owners here want windows that match the quality of the house, which often means wood-clad or fiberglass, custom sizes and big doors to the yard.

What matters when replacing windows in an Alamo home.
Alamo’s older ranch homes often have original single-pane windows, while larger estates may have dozens of windows in custom shapes. Both benefit from planning: matching sizes and grids exactly, and ordering every unit together so the house looks consistent.
Because Alamo is unincorporated, window permits go through Contra Costa County rather than a city. Gated communities like Round Hill add their own architectural review. We prepare the submittals, handle the permit, and order once everything is approved.
Alamo summers are hot, and homes toward the Las Trampas foothills can sit in high fire hazard zones that call for tempered glass. We check your address against the state fire map and choose glass that handles both the heat and the rules.
Homes along I-680 and Danville Boulevard do best with laminated or sound-rated glass in the bedrooms.
Tall entry doors with sidelites and multi-slide patio doors are common upgrades, and we check headers before recommending large openings.
Wood-clad windows give estate interiors real wood while the aluminum exterior stands up to the sun.
