Fast, Reliable General Contractor Across Berkeley
Hiring a general contractor in Berkeley means navigating three things at once: a house that’s often 80 to 100 years old, a permit desk with real teeth, and a job site squeezed onto a narrow lot with neighbors six feet away. Penhallow Remodeling handles all three. We give you a written price before any work starts, show up in the window we promised, and put a 365-day guarantee on the finished job in writing. Call (936) 259-2607 to schedule a free estimate, and we’ll walk the site with you before you commit to anything.
Trevor Nash leads our General Contractor team, and he’s the one who makes sure your number on day one is the number on the invoice. No change orders that appear out of nowhere. No verbal ballpark that becomes a different number after demo.
Why Penhallow Remodeling Is Berkeley’s Preferred General Contractor Company
Berkeley homeowners have seen the full range. The contractor who never showed. The crew that left a dumpster blocking the shared driveway for three weeks. The estimate that doubled once the wall came open. We built our process to be the opposite of that. Every job starts with a written price, a defined arrival window, and a written guarantee. When you call, a real person answers – day or night – not a voicemail prompt that sends you in circles.
Our technicians are background-checked and arrive in uniform. You’ll know exactly who’s walking into your home, and they’ll explain what they’re doing in plain English. If a term like substrate comes up, we’ll tell you it’s the moisture-resistant layer behind your tile, not leave you guessing.
We operate under The Kingswell Way, the standard set in 2004: say the price before the work, show up in the window we gave, leave the place cleaner than we found it. We’re part of the Kingswell family of companies, independently owned and operated, with dispatch coordinated from our San Francisco Bay Area office. Crews serve Berkeley directly.
General Contractor Services in Berkeley
General Contractor Services in Berkeley cover the full scope of a remodel: structural changes, rough-in plumbing and electrical, drywall, flooring, cabinetry, countertops, finish work, and the permit coordination that ties it all together. This isn’t a handyman call. When you’re moving walls, opening floors, or reconfiguring a bathroom, you need someone who can sequence the work so inspections pass the first time and the project doesn’t stall.
Kitchen and Bath Remodeling
A full kitchen remodel in Berkeley typically runs $14,000 to $45,000, depending on cabinet line, countertop material, and whether you’re moving plumbing or gas lines. Bathrooms land between $9,000 and $28,000. We install KraftMaid and Wellborn cabinetry, and Cambria or Silestone quartz, which carry their own manufacturer warranties alongside our written 365-day guarantee.

Structural and Permit-Heavy Work
Berkeley’s older housing stock means many remodels turn into structural projects once walls open. Cripple-wall bracing, foundation bolting, and load-path upgrades are common on pre-1940 flats. We pull the combined permits, coordinate the engineering, and keep the draw schedule moving so you’re not waiting weeks between inspections.

Construction Company in Berkeley
As a Construction Company in Berkeley, we take on the jobs that require substantial sequencing: whole-home remodels, room additions, and ADUs. These projects have moving parts – structural engineering, foundation work, framing, weatherproofing, mechanicals, and finish trades – and the general contractor’s job is to hold the schedule together without surprises.
Additions and ADUs
Home additions in Berkeley generally run $45,000 to $130,000. ADU construction ranges from $90,000 to $220,000, and the number moves significantly based on whether your lot triggers hillside, geotechnical, or fire-zone review. We’ll give you a written number before permit submittal, not after.
Whole-Home Coordination
When a project touches multiple systems at once, the quote has to account for staging, dumpster placement, material delivery, and neighbor access. We scope what’s in the walls. We confirm the demand load on the panel. And we build the schedule backward from the inspection sign-off so the finish date is real, not aspirational.
Trusted Brands We Service in Berkeley
We don’t install brands we can’t stand behind. On Berkeley projects, that means KraftMaid and Wellborn cabinetry, Cambria quartz, Kohler and Moen fixtures, and James Hardie siding when the scope reaches the exterior. For hillside jobs in the Wildland-Urban Interface, we spec fire-resistant materials that meet Berkeley’s post-1991 code requirements. We maintain local parts relationships in the East Bay so a damaged cabinet door or a wrong finish doesn’t stop a project for two weeks.
Common General Contractor Problems We See in Berkeley Homes
- Soft-story retrofit deadlines on pre-1960 multi-unit buildings. Berkeley assigns compliance tiers by risk, and many owners learn about their deadline when a remodel permit triggers review. If the retrofit isn’t scoped into your project schedule from day one, every inspection after that slips.
- Wildland-Urban Interface requirements on hillside lots. Homes in the hills, especially rebuilds after the 1991 Tunnel Fire, carry venting, siding, and roofing rules that flatlands contractors routinely underpriced. That mistake lands on the owner as a change order.
- Staging on narrow lots and shared driveways. A Berkeley flatlands lot often has no driveway at all, or one shared between two or three units. Parking a dumpster or stacking lumber in the wrong spot gets complaints, and complaints turn into stop-work calls fast.
- Unknown structural conditions behind original plaster. Many 1920s Craftsman bungalows off Shattuck and Sacramento have unbraced cripple walls and mixed framing from decades of piecemeal updates. You won’t know until the wall opens, but a written quote should include a defined allowance for exactly this.

FAQs About General Contractor in Berkeley
Yes, and it should be scoped into your project from the first site visit. Berkeley’s Soft-Story Retrofit Ordinance assigns compliance deadlines by risk tier, and any substantial remodel on a pre-1960 multi-unit wood-frame building will almost certainly trigger retrofit review. A contractor who doesn’t know this will hand you a permit schedule that falls apart at the first inspection. We pull a combined permit that covers the retrofit scope, the remodel scope, and the inspection sign-off in the right sequence. Call (936) 259-2607 to have us check your building’s tier before you sign anything.
It means your remodel must meet fire-resistant construction standards that don’t apply to flatland homes. Post-1991 fire codes require specific venting, siding, and roofing materials on hillside lots in the WUI zone, and those requirements add real cost and material constraints. We spec James Hardie siding and fire-rated assemblies where the code calls for them, and we write those line items into your quote instead of discovering them mid-project. Call (936) 259-2607 for a hillside-specific estimate.
Yes, and we plan for it before the first delivery. On a 1923 Craftsman bungalow off Shattuck Avenue in North Berkeley, we staged a kitchen remodel in the driveway under a tarp to keep a narrow shared driveway clear for the neighbor. Material deliveries were scheduled in single-day windows. Party-wall notice went out before any structural work started. The staging plan affects the quote, because labor and logistics on a constrained site cost more than an open suburban lot with street frontage. We’ll walk your site and show you exactly how the staging works before you commit.
We pull the permits, schedule the inspections, and manage the sign-off process end to end. Berkeley’s permit workflow is slower and more detailed than neighboring cities, partly because of the soft-story and WUI overlays and partly because the city’s Residential Building Record disclosure system demands more documentation. A remodel that would sail through in Albany may need three extra weeks and two additional inspections in Berkeley. We build that into the schedule up front, so you’re not getting surprised on week six. Estimates are free – call (936) 259-2607.
Yes. Every project gets a written price before any work starts, and any allowance or change order is written, signed, and dated before we proceed. The number you approve on day one is the number on the invoice unless you ask us to change the scope. If something fails inside the 365-day guarantee period, we come back and fix it at no charge, and we put that promise in writing on every job. Call (936) 259-2607 for a free, written estimate.
