Construction Services in San Carlos, CA
If you own a home in San Carlos, you’ve probably already learned that construction here isn’t like construction in the flat towns next door. The moment a remodel opens a wall in a 1950s ranch on Eaton Avenue, or an addition gets planned for a hillside lot off Brittan Avenue, the real conditions of this city show up: cripple-wall foundations, clay soils that move with the seasons, and wind that dries concrete before it’s finished. Barrett & Sons Construction has worked through all of it, and we answer our own phone when you call (877) 610-1318.
We’re not going to pretend any of this is easy, and we’re not going to give you a phone quote that changes at the door. What we will give you is a written scope, a written allowance sheet, and a written change order before anything changes. Tom Barrett puts his name on every job, and his sons run the crews. That’s the whole structure.

Why San Carlos Homeowners Choose Barrett & Sons Construction
We built our reputation the slow way, one permit inspection at a time. Homeowners in the White Oaks flats and up in the hills west of Alameda de las Pulgas have seen the same thing happen too often: a contractor quotes a number over the phone, then finds “unexpected conditions” once the drywall comes down. In San Carlos, unexpected conditions aren’t unexpected at all. We know what’s behind these walls before we open them, because we’ve opened hundreds of them in 94070.
Tom Barrett founded this company in 1998. His sons run the crews. The license number, the address, the name, all published and verifiable before you sign anything. We carry background-checked, uniformed crew members who show up with the Barrett & Sons name on their shirts and their work. And every job, from a small fence replacement to a full kitchen gut, carries the 90-Day Done Right Promise in writing: if it isn’t done right, one call brings Tom back.
Construction Services We Offer in San Carlos
Kitchen Remodeling
We install KraftMaid and Cambria in Kitchen Remodeling - San Carlos projects, not mystery brands off a van. On 1950s ranch homes near El Camino Real, we plan for the wiring and plumbing age before we order a single cabinet.
Learn more about our Kitchen Remodeling in San Carlos.

Bathroom Remodeling
Bathroom Remodeling - San Carlos homes often sit on original slab or hold old cast-iron drain lines that need attention before new tile goes down. We scope that work in writing before we start, so the number on your contract is the number you pay.

Roofing
The wind corridor through San Carlos puts real stress on San Carlos Roofing, especially on exposed hillside streets. We install GAF and CertainTeed systems and we pull permits on every eligible roof, because the inspector works for you, not for us.

Windows & Doors
Windows & Doors in San Carlos from Andersen and Marvin hold up to the afternoon wind far better than builder-grade units. We measure, order, and install with an eye on how each opening affects the rest of the wall.
Learn more about our window and door work as part of your San Carlos project by calling (877) 610-1318.

Fence Installation
Hillside fence lines in San Carlos need posts set below the clay movement zone, or you’ll be re-setting them in three years. We build fences that stay plumb on the flats and stable on the slopes.

Driveway & Pavers
The clay-heavy soils west of Alameda de las Pulgas heave driveways every wet season. We specify deeper base and proper drainage, using Belgard and Techo-Bloc pavers that you can look up by name.

Home Additions & ADU
San Carlos is pushing ADUs hard, and most of the viable lots are on hillsides with geotechnical conditions that demand engineered foundations. We pull the permits, schedule the inspections, and hand you the signed paperwork when it’s done.

Neighborhoods We Serve in San Carlos
We work across the entire 94070 ZIP code, from the flats near El Camino Real to the hillside streets above Brittan Avenue. The terrain changes fast in San Carlos, and our scoping changes with it. Typical response time for an estimate in San Carlos is within a few days, depending on the scope.

Why San Carlos’s Climate & Housing Affect Construction
San Carlos sits in a natural gap in the Coast Range, which means afternoon wind comes through hard off the Bay. In summer, that wind dries concrete flatwork and stucco faster than the curing schedule allows if you aren’t paying attention, so pour timing has to account for it. In winter, that same corridor pushes moisture inland, and the wet season lands on expansive hillside clay that swells and shrinks through March.
The housing stock makes it more complicated. Most homes here went up as Peninsula bedroom-community infill between the 1940s and 1960s, and many still sit on original slab or cripple-wall foundations. Any significant remodel in San Carlos means opening walls that haven’t been touched in 50 to 70 years, finding wiring, framing, and plumbing that predates current code. On hillside lots, those homes also sit on clay that heaves driveways and step-cracks foundations. Contractors who don’t specify pier-and-grade-beam or deepened footings on those lots get called back within a few years. We’d rather do it once.
Pricing for Construction in San Carlos
Construction pricing in San Carlos reflects the terrain and the age of the housing stock more than anything else. A simple interior remodel in the flats runs differently from an addition on a hillside lot that needs soils reports and engineered footings. Here are honest ranges we see in this market:
- Kitchen remodel: $45,000-$110,000 depending on layout, cabinet grade, and what’s behind the walls
- Bathroom remodel: $22,000-$55,000 depending on waterproofing scope and drain-line condition
- Roof replacement: $14,000-$32,000 depending on pitch, access, and material
- Windows & doors: $900-$3,200 per opening installed, depending on brand and frame condition
- Fence installation: $4,500-$14,000 depending on linear feet and slope
- Driveway & pavers: $12,000-$45,000 depending on base depth and drainage needs
- ADU / home addition: $180,000-$500,000+ depending on site conditions and finish level
Every estimate is free, and every allowance and change order arrives in writing before work proceeds. Call (877) 610-1318 and we’ll walk the site with you.

FAQs About Construction in San Carlos
A kitchen remodel in San Carlos typically runs between $45,000 and $110,000, with hillside homes on the higher end due to foundation access and structural reinforcement needs. The spread depends on whether we’re reconfiguring plumbing and electrical in a 1950s rancher or doing a cabinet and counter refresh. Call (877) 610-1318 for a written, line-item estimate.
No, not without a written change order you sign first. Every allowance, every scope adjustment, every surprise behind the wall gets priced in writing before a single nail moves. The allowance that isn’t on paper is a surprise waiting for a date.
Yes, on every eligible job. San Mateo County scrutinizes grading and excavation permits on hillside lots for erosion control compliance, and the City of San Carlos requires permits for structural, electrical, plumbing, and roofing work. We pull them, we schedule the inspections, and we hand you the signed paperwork.
Hillside lots west of Alameda de las Pulgas sit on clay-rich soils that swell in winter and shrink in summer, heaving driveways and causing step-cracks in 1950s-60s foundations. Most significant construction on those lots requires engineered foundations, soils reports, and retaining wall permits that flat-terrain cities don’t demand. If the contractor doesn’t mention soils, find a different contractor.
We offer a permanent 10% discount for seniors and veterans, a $40 discount on any repair over $200, a free second opinion on any written estimate, and no trip charge inside San Mateo County. Call (877) 610-1318 to schedule your free estimate.

What San Carlos Customers Say
"Genuinely good builders and I would use them again. Site tidiness slipped a bit in the middle stretch and I had to mention it, after which it was spotless every evening."
- Marcus Threadgill"Every change to the price came as a written change order before the work happened, not as a surprise on the final bill. I did not know contractors still did that."
- Xiomara Benavides"Tom Barrett was on our job most days himself, not just at the quote and then never again. When something needed deciding there was an actual person to decide it with."
