AfterConstruction Services in Alamo, CA
Construction in Alamo, CA means working with Contra Costa County, not a local building department, and that single fact changes how permits, timelines, and fire-safe code requirements get handled. Barrett & Sons Construction knows this because we pull Alamo permits all the time, which means driving paperwork to the County offices in Martinez, not dropping it at a city hall down the street. If you’re planning a remodel, addition, or new build in 94507, call (877) 610-1318 and you’ll get Tom Barrett or one of his sons on the line.

Why Alamo Homeowners Choose Barrett & Sons Construction
We’re the owner-operated crew that answers our own phone, and the owner’s sons run the jobs. Tom Barrett founded this company in 1998, and his name, address, and license number are published for anyone to verify before signing anything. In Alamo, we’ve worked on homes along Stone Valley Road, up into the Roundhill Country Club area, through the Las Trampas foothills, and down toward Alamo Square. Each job gets permits pulled, inspections signed, and every change in scope arrives as a written change order before a single nail moves. We carry KraftMaid and Cambria in kitchens, GAF and CertainTeed on roofs, and Andersen and Marvin on windows; materials you can look up, not mystery brands off a van. And every project carries our 90-Day Done Right Promise: if it’s not done right, one call brings Tom back to make it right.
Construction Services We Offer in Alamo
Kitchen Remodeling
Alamo kitchens lean large and built for entertaining, which means we’re usually opening up walls, reconfiguring islands, and upgrading to premium cabinetry and stone. We handle the full scope: layout, plumbing, electrical, cabinetry, counters, and finish work, all with permits pulled and inspections signed.
Learn more about our Kitchen Remodeling in Alamo.
Bathroom Remodeling
From a powder room refresh to a full primary suite expansion, Alamo bathrooms often sit in homes built between the late 1960s and the 1990s, so we’re frequently correcting outdated plumbing, waterproofing, and ventilation. Every bathroom job includes written allowances so you never get surprised by a fixture upgrade cost.

Roofing
Alamo sits within a State Responsibility Area High Fire Hazard Severity Zone in many foothill sections, so re-roofing here typically involves Chapter 7A fire-safe materials like Class A shingles, ember-resistant vents, and ignition-resistant underlayment. We’re GAF and CertainTeed certified, and we pull the County permit every time.

Windows & Doors
The hot, dry Alamo summers accelerate moisture loss in exposed wood framing, so window and door replacements need weatherproofing sequenced correctly from day one. We install Andersen and Marvin products and handle everything from a single cracked pane to full-home replacement.
Fence Installation
Large lots and hillside terrain shape most Alamo fence projects; we’re building redwood privacy fences, ranch-style perimeter fencing, and gates that hold up to the Diablo winds. We handle the County setback and height requirements so your fence doesn’t become a neighbor dispute later.
Driveway & Pavers
Alamo’s expansive Diablo clay soils swell and shrink with the seasons, which means driveway base preparation matters more here than in most places. We install Belgard, Techo-Bloc, and Cambridge Paver systems with compacted base layers engineered for our soil conditions.
Home Additions & ADU
Most Alamo additions we build are tied to the same goal: more square footage without losing the character of a custom or semi-custom home. We manage the full County permit path for ADUs and additions, including the fire-safe construction checklist that Contra Costa County’s Title 7A review adds to the process.
Neighborhoods We Serve in Alamo
We’re in and out of Alamo neighborhoods every week; you’ll see our trucks on Stone Valley Road, up near Roundhill Country Club, along Livorna Road, in the Las Trampas foothill streets, and down around Alamo Square. When you call, we typically have a crew in the area within a day or two for an estimate walk-through.

Why Alamo’s Climate & Housing Affect Construction
Alamo is unincorporated, which means every construction permit routes through the Contra Costa County Department of Conservation and Development in Martinez, not a local city hall. Contractors who mistake Alamo for neighboring Danville, which has its own building counter, end up filing wrong paperwork and stalling projects by weeks. We know the County process, and we build the extra review time into our schedules so you’re not left wondering why the permit hasn’t cleared.
Then there’s the fire zone piece. Large portions of Alamo fall within a State Responsibility Area High Fire Hazard Severity Zone, which makes Chapter 7A fire-safe construction a mandatory code layer on nearly any new build or significant remodel in the foothills. That means ignition-resistant siding, ember-resistant vents, and defensible-space grading are not optional add-ons here; they’re code. We’ve walked enough Alamo jobs to know the Title 7A checklist cold.

FAQs About Construction in Alamo
Construction in Alamo typically runs 15 to 30 percent higher than tract-home communities across the county because the housing stock is custom and semi-custom, the lots are large, and fire-safe materials are often mandatory. A kitchen remodel starts around $65,000, a bathroom around $25,000, and an ADU project likely starts around $250,000 depending on site conditions. Call (877) 610-1318 for a free, written line-item estimate.
Alamo is an unincorporated community with no municipal government, so the Contra Costa County Department of Conservation and Development in Martinez handles every building permit, rather than an Alamo city hall. This can add review time, especially when the fire-safe Title 7A checklist applies to your parcel.
If your parcel sits within the State Responsibility Area High Fire Hazard Severity Zone, which covers much of the Alamo foothills, then yes, Chapter 7A fire-safe construction is mandatory for any new build or significant remodel. That means ignition-resistant siding, ember-resistant vents, and defensible-space grading. We’ll check your parcel before we bid so you know what’s required.
It won’t change unless you change the scope, and if that happens, you’ll get a written change order before any new work begins. That written-order rule applies to every Barrett & Sons job, no exceptions. If a contractor in Alamo tells you permits are optional or prices are verbal, ask them to put it in writing.
Yes, every eligible job gets permits pulled and inspections signed through Contra Costa County. We don’t treat permits as optional; the permit inspector works for you, not for me, and that’s exactly why we like having them on every job.

What Alamo Customers Say
"Came back a year later to sort a door that had dropped as the frame settled. No charge and no argument about whether it was covered."
- Thaddeus Oyelowo"Addition over the garage matched the original roofline and brickwork so closely that visitors do not realise it was added. He tracked down the closest brick he could find rather than settling."
- Gideon Stroud"The bathroom was finished on the day he said at the start, which nobody had led me to believe was possible."
- Loretta Vanterpool
