Why Foster City Homeowners Choose Barrett & Sons Construction
Most of the people we work with have already been through one bad remodel. They hired a company that quoted a price over the phone, then showed up with a different number and a shrug. That doesn’t happen here. Tom Barrett founded this company in 1998, and the crews working in Foster City today include his sons. The name on the truck is the name that answers when something isn’t right.
We’ve done work in the Dolphin Bay and Whaler’s Island neighborhoods, and a lot of our Foster City jobs come from neighbors talking over fences. The 90-Day Done Right Promise is written on every contract: if it’s not done right, one call brings Tom back. No fine print, no voicemail maze. A live person answers our phone around the clock, and every price change arrives as a written change order before work moves forward. Permits get pulled on every eligible job, and inspections get signed. You can look up our license number yourself before you sign anything. We expect you to.
Construction Services We Offer in Foster City
Kitchen Remodeling
Kitchens in Foster City tract homes often sit on post-tension slabs that complicate plumbing relocations, so we plan the scope around what your foundation actually allows. We install named brands you can research, and every allowance is in writing from the start. Learn more about our Kitchen Remodeling in Foster City.
Bathroom Remodeling
Bathroom remodels here frequently reveal slab cracking from decades of slow Bay mud consolidation, and addressing that early keeps costs predictable. We pull permits, coordinate inspections, and hand you a written change order before any scope shift touches the job. Learn more about our Bathroom Remodeling in Foster City.
Roofing
Salt-laden air off the tidal lagoons shortens the life of standard flashing and fasteners, so we specify materials that hold up under constant coastal moisture. Tear-off and reroof jobs trigger the same geotechnical awareness we bring to every Foster City project. Learn more about our Roofing in Foster City.
Windows & Doors
Replacing Windows & Doors in Foster City in these 1964-1985 build-outs often means working with framing that has shifted subtly over the decades. We carry Simonton and Ply Gem lines, and we square the openings rather than forcing new units into old geometry.
Fence Installation
Fence posts set in Foster City’s engineered fill need deeper footing than they would a mile inland, especially anywhere near the lagoon edges. We plan for that before we dig, so the fence stays plumb through the wet season.
Driveway & Pavers
Poured concrete and paver driveways here sit on compressible Bay mud, which means base prep matters more than it does on solid ground. We over-excavate and reinforce where the soil report tells us to, and we show you the report’s reasoning before we pour.
Home Additions & ADU
Second-story additions in Foster City routinely hit a wall when the 1970s slab can’t carry the load without engineered reinforcement. We’ve worked through that process enough times to tell you honestly, before you spend money on plans, what the geotechnical picture likely demands. More about our construction services is on our home page.
Neighborhoods We Serve in Foster City
We run projects throughout Foster City, from the lagoon-front homes near Marlin Avenue to the quieter cul-de-sacs off Edgewater Boulevard. Our typical response time for a Foster City estimate visit is within one business day.

Why Foster City’s Climate & Housing Affect Construction
Foster City was built almost entirely on engineered fill dredged from San Francisco Bay starting in the 1960s. Virtually every project here sits on compressible Bay mud with real liquefaction risk and ongoing differential settlement potential. That is not a footnote. It changes how foundations get designed, how additions get engineered, and why a simple bathroom remodel can turn up slab cracking that a contractor in San Mateo would never see. Contractors who work in Foster City routinely deal with deep pile or grade-beam foundation requirements mandated by the soil conditions, and even routine permits trigger geotechnical scrutiny that would be unnecessary a mile inland.
The second local factor is the salt air. The network of tidal lagoons running through the city means metal fasteners, flashing, and even reinforcing steel corrode faster than they do just a few miles from the water. We choose exterior materials, from our Roofing in Foster City flashing to window frames to fence hardware, with that salt exposure in mind. A galvanized bracket that would last thirty years in Belmont might fail in fifteen here. The housing stock, almost uniformly from the 1964-1985 master-planned build-out, was designed as a unit, which means the original specs were consistent but the ground underneath each lot is not. That combination, uniform homes on inconsistent fill, is the central fact of Foster City construction. We plan around it from day one.
Pricing for Construction in Foster City
Honest numbers depend on the soil report, the scope, and what’s hiding inside the walls, but here’s what we typically see in Foster City:
- Bathroom remodels: $18,000-$42,000, with foundation repairs adding $3,000-$12,000 when slab cracking shows up.
- Kitchen remodels: $35,000-$85,000, depending on layout changes and whether the slab needs work around plumbing moves.
- Second-story additions: $250,000-$450,000+, because the 1970s slab-on-fill usually needs engineered reinforcement before framing starts.
- Roof replacements: $14,000-$38,000, with salt-rated flashing and fasteners included by default.
- Driveway and paver work: $12,000-$35,000, based on over-excavation depth and base reinforcement.

FAQs About Construction in Foster City
A second-story addition in Foster City typically runs $250,000 to $450,000 or more, and the wild card is almost always the existing foundation. The 1970s slab-on-fill under many of these homes was never designed to carry another level, so engineered reinforcement often becomes the first line item before framing even starts. Call (877) 610-1318 for a written estimate that covers the foundation question directly.
Because your house sits on engineered fill over compressible Bay mud, and the building department knows it. Foster City’s soil conditions create liquefaction risk and differential settlement potential that most neighboring cities on natural ground don’t face. A geotechnical report tells us, and the permit inspector, what your specific lot can handle. We don’t skip it, and we don’t hire contractors who suggest you should.
Only if the scope changes, and only after you sign a written change order approving it. That’s the rule on every Barrett & Sons job. An allowance that isn’t on paper is a surprise waiting for a date, and we’d rather hand you a boring piece of paper than a surprise invoice. If the inspection or the soil report reveals something we couldn’t see on the surface, you’ll know the cost before the work proceeds.
Yes, on every eligible job. Permits and inspections are not optional in Foster City, and any contractor who tells you otherwise is setting you up for a disclosure problem when you sell. The permit inspector works for you, not for us, and we like it that way. It keeps everyone honest.
Most kitchen remodels in Foster City run eight to twelve weeks, and bathrooms typically run four to seven weeks. Foundation complications, which are more common here than a mile inland, can add a week or two. We’ll put the timeline in writing with your estimate, and we’ll update it in writing if conditions change. Call (877) 610-1318 to get a schedule and a number, not a guess.

What Foster City Customers Say
"The bathroom was finished on the day he said at the start, which nobody had led me to believe was possible."
- Loretta Vanterpool"His sons run the crews and they were in our house for four months. Not once did I feel I had to be home to keep an eye on things."
- Camila Fuentes"Beautiful work and honest pricing throughout. The project ran about three weeks past the estimate waiting on the cabinets, which was the supplier rather than him, though the delay was still real."
