AfterConstruction Services in Danville, CA
Finding a contractor in Danville who actually shows up when promised, pulls permits without being asked, and leaves a clean job site is harder than it should be.

Our crews know the valley, the inspectors, and the soil you’re building on. Call us at (877) 610-1318 for a free estimate, and Tom Barrett or one of his sons will be the one walking your property, not a sales rep flown in for the week.

Why Danville Homeowners Choose Barrett & Sons Construction
Most of our Danville work comes from referrals. A neighbor sees a kitchen going in on El Pintado, likes the crew’s manners, and calls us. That’s how Tom Barrett has run things since 1998, and it hasn’t changed. In neighborhoods like Greenbrook and Sycamore, we’re known for leaving the site broom-clean and never surprising a homeowner with a bill that wasn’t already in writing.
Every Danville job gets a written change order before a single board moves, permits pulled and inspections signed where the law requires them, and the 90-Day Done Right Promise in the contract. Tom’s name, address, and license number are on every quote. Look us up in Alamo or Blackhawk, ask around at the Danville farmers market on Railroad Avenue. The work holds up.
Construction Services We Offer in Danville
Kitchen Remodeling
We install KraftMaid and Cambria in Danville kitchens, with crews led by Tom’s sons. From Greenbrook galley kitchens to full Blackhawk chef kitchens, the cabinets and counters are brands you can research before we ever start.
Kitchen Remodeling in Danville
Bathroom Remodeling
Shower pans, tile, vanities, venting: we’ve done dozens of Danville baths, including tricky remodels in 1970s split-levels where the plumbing stack doesn’t cooperate. Permits are pulled on every eligible job, and we don’t hide that from the inspector.
Bathroom Remodeling in Danville
Roofing
GAF and CertainTeed shingles, underlayment spec’d for Danville’s wet winters, and Class A fire-rated assemblies for hillside homes near Blackhawk. Summer Delta winds in the San Ramon Valley affect how we schedule tear-off and installation days.
Windows & Doors
Andersen, Marvin, Simonton, and PGT are all brands we install, trimmed to match Danville home styles from 1980s ranches to newer custom builds. If you’re in a Blackhawk HOA, we know the window and door finish standards the Architectural Review Committee enforces.
Fence Installation
Cedar, composite, and metal post options, with concrete piers deep enough for Danville’s expansive clay. We handle HOA submittals for Blackhawk fence projects, because that committee has its own opinion on everything.
Driveway & Pavers
Belgard and Techo-Bloc pavers laid over properly compacted base. In Danville, the clay below moves with the seasons, so driveway prep here is not the same job it is in the flatter East Bay.
Home Additions & ADU
Second-story additions, ground-floor master suites, and detached ADUs with full kitchen and bath. Danville’s 94506 hillside setbacks and 94526 post-tension slabs each have their own retrofit requirements.
Neighborhoods We Serve in Danville
We work all over Danville, from the Sycamore and Greenbrook neighborhoods on the flat side of 680 to the custom homes around Blackhawk Country Club and the smaller cul-de-sac pockets off Diablo Road. Our crews live in the broader Bay Area and typically schedule a site visit within a couple of days of your call.

Why Danville’s Climate & Housing Affect Construction
Danville sits at the base of the Diablo Range foothills, and the soil under much of the valley floor is what’s called Altamont-series expansive clay. It swells in wet winters, shrinks in dry summers, and moves enough to crack slabs and heave shallow foundations. In the 94526 tract ranch and split-level homes built in the 1970s and 1980s, we regularly find post-tension slab cracks that trace right back to that seasonal movement. When we add on to a room or pour a driveway here, we over-excavate and import engineered fill, and we set footings deeper than minimum code. It’s not cheap; it’s what Danville dirt demands.
Then there’s the hillside side of town. Blackhawk and other 94506 communities fall under CAL FIRE’s State Responsibility Area with a Wildland-Urban Interface hazard designation. That means Class A fire-rated roof assemblies, ignition-resistant exterior materials, and detailed defensible-space awareness during construction. A contractor who only builds in flat-valley San Ramon may know the codes on paper. We’ve worked under them, and so have the inspectors who sign off on our Danville jobs.

FAQs About Construction in Danville
Yes, for almost every remodel beyond cosmetic finish work. Danville requires permits for structural changes, kitchen and bath plumbing, electrical, roofing, windows, and additions, and if you’re in Blackhawk, you also need Architectural Review Committee approval before the city will even look at your permit application. Call (877) 610-1318 and we’ll tell you what your project triggers before you sign anything.
Expect $45,000 to $110,000 for a typical Danville kitchen remodel in 2026, with Blackhawk custom kitchens running higher due to HOA material standards and more complex structural conditions. We give you a written, line-item quote so you know exactly where the money goes. Call (877) 610-1318 for a free estimate on your specific kitchen.
Yes, and anyone who tells you otherwise hasn’t built there. The Blackhawk HOA Architectural Review Committee has its own application, its own meeting schedule, and its own list of approved materials and colors. We’ve seen completed work torn out because a contractor skipped that step. We hand you the HOA submittal packet before the city submittal begins, and we build HOA review time into the schedule. Call (877) 610-1318 if you have a Blackhawk project on your mind.
The main culprit is the expansive Altamont clay under much of Danville. It swells when the San Ramon Valley gets its winter rains and shrinks through the dry summers, and over 40 or 50 years that movement shows up as slab cracks, sticking doors, and retaining wall lean. We address it with deeper footings, imported fill, and proper drainage on every ground-up or addition project in Danville. Call (877) 610-1318 to have Tom walk your property and tell you what he sees.
Not unless you ask for something different, and even then it comes to you as a written change order before the work proceeds. That’s a Barrett & Sons rule, not a suggestion. The allowance that isn’t on paper is a surprise waiting for a date, and you won’t get that from us. Call (877) 610-1318 for a fixed, written quote on your Danville project.

What Danville 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
