AfterRemodeling Company in Kensington, CA
Home remodeling in Kensington runs $9,000 – $130,000 depending on scope, with most whole-house projects falling between $45,000 and $130,000. Every job here faces a dual regulatory burden: Contra Costa County permits through Martinez plus seismic-retrofit and Wildland-Urban Interface fire-hardening requirements that don’t exist in neighboring Berkeley. We’re Penhallow Remodeling, and we handle both layers before the first wall comes down. Call (936) 259-2607 for a free written estimate.
Kensington’s 1920s – 1940s Craftsman bungalows and Period Revival homes sit on steep hillside lots with unreinforced foundations, cripple walls without anchor bolts, and cut-and-fill grades that shift with the seasons. The marine fog rolling off the bay soaks west-facing siding year-round, while fall Diablo winds bring ember-risk that shapes every roofing and venting decision we make. We don’t guess at these conditions. We price for them up front.
Why Kensington Homes Are Different
Kensington isn’t a city. It’s an unincorporated pocket of Contra Costa County perched directly atop the Hayward Fault, and that single fact changes everything about how we build here. Permits don’t go to Berkeley’s Accela portal; they route to the county Building Inspection Division in Martinez, with its own fee schedules, plan-check queues, and code interpretations. Contractors accustomed to Berkeley’s faster turnaround get caught flat-footed. We don’t.
The housing stock tells the rest of the story. Most homes are ninety to a hundred years old, built on hillsides with unreinforced brick or concrete perimeter foundations, undersized cripple walls, and crawl spaces that were never bolted to their frames. When we open a wall or foundation for a remodel, we almost always find unstable fill, moisture-damaged framing from decades of fog exposure, or both. Seismic retrofitting isn’t an add-on here. It’s embedded in the scope.
Then there’s the climate paradox. The same marine layer that greens the hills rots west-facing siding and wicks moisture into foundations. But those hills also sit in the Wildland-Urban Interface, where Diablo winds in October and November create extreme fire weather. The 1991 Oakland-Berkeley Hills fire reached Kensington’s borders. Every roof replacement, every vent upgrade, every deck rebuild must satisfy both moisture management and ember-resistant assembly requirements. Two masters. One crew. That’s the job.
Our Main Kensington Services
Most Kensington homeowners who call us start with one of these three projects, each shaped by the conditions above.
General Contractor in Kensington
As your General Contractor in Kensington, we coordinate the county permits, the seismic engineering, and the WUI compliance so you don’t have to chase three separate workflows. We’ve seen East Bay GCs lose weeks because they filed Berkeley-style paperwork with Contra Costa County. We file it right the first time. Every project gets a written price before work starts, a real arrival window, and our 365-Day Done Right Promise in writing.
Bathroom Remodeling in Kensington
Bathroom Remodeling in Kensington means working around hillside plumbing runs, venting through fire-rated assemblies, and often sistering rot-damaged floor joists where decades of fog have done their work. We install Kohler and Moen fixtures, Cambria and Silestone surfaces, and we guarantee the waterproofing for 365 days. The price you sign is the price you pay.
Kitchen Remodeling in Kensington
A Kitchen Remodeling in Kensington project typically opens walls that haven’t been touched since the 1930s. We find knob-and-tube remnants, unbolted cripple walls, and moisture damage in the same demo sequence. We plan for it. Our Home Remodeling crews carry KraftMaid and Wellborn cabinetry, source Cambria and Caesarstone countertops, and leave you a written guarantee before the first cabinet goes in.

Home Remodeling in Kensington
Home remodeling in Kensington demands a contractor who understands unincorporated Contra Costa County permitting, seismic retrofit integration, and WUI fire-hardening compliance as standard practice, not afterthoughts. Most of our Kensington whole-house projects start with a 1920s – 1940s bungalow on a steep lot with an unreinforced foundation, and every one of them gets a written price before we touch a wall. Our Home Remodeling process is built for these conditions.
Whole House Remodel
Signs you need it
Your home hasn’t had a systems update in thirty-plus years, the floor plan doesn’t match how you live, and every contractor who walks through mentions the unbolted foundation before they mention the kitchen.
What it costs in Kensington
A whole house remodel in Kensington typically runs $45,000 – $130,000, with most projects landing between $65,000 and $95,000 depending on foundation work, seismic retrofit scope, and WUI compliance requirements.
How we do it
We start with a structural assessment and Contra Costa County permit strategy, then sequence demolition, seismic retrofit, systems rough-in, and finish work so each trade passes inspection before the next one starts.
Home Renovation
Signs you need it
Specific rooms are failing, you’ve got localized moisture damage from fog exposure, or you’re updating for resale while the foundation and framing can still support selective work without full seismic intervention.
What it costs in Kensington
Home renovation projects in Kensington typically range from $9,000 for focused single-room updates to $45,000 for multi-room work that doesn’t require foundation-level intervention.
How we do it
We isolate the renovation zone, protect the existing structure, address any hidden moisture or seismic issues we expose, and finish with materials from recognized trade brands that carry their own warranties alongside ours.

| Garage Conversion | $30,000 – $80,000 |
Do I need seismic retrofitting with my home remodel in Kensington?
Almost always, yes. Contra Costa County requires seismic review for any significant structural modification, and the 1920s – 1940s foundations we typically encounter lack anchor bolts and have undersized cripple walls. We include this assessment in our initial scope and price it into your written estimate so there’s no surprise after demo. Call (936) 259-2607 to schedule a free evaluation.
How long does a whole house remodel take in Kensington?
Most whole house remodels in Kensington take six to ten months, with two to four weeks of that being Contra Costa County plan-check and inspection scheduling in Martinez. We build that timeline into your written contract, including permit submission dates and inspection milestones, so you know where the project stands at every phase. Call (936) 259-2607 for a timeline specific to your home.

Three factors push Kensington prices above East Bay averages: Contra Costa County permit fees and the additional plan-check cycles for seismic and WUI compliance; foundation and cripple-wall work that most hillside homes require; and fire-resistant material upgrades for roofing, venting, and decking assemblies. We identify all three in your written estimate before you sign, so the number on day one is the number on the invoice.

FAQs About Remodeling Company in Kensington
Contra Costa County Building Inspection Division in Martinez, not the City of Berkeley. This trips up contractors who assume Berkeley’s Accela portal applies. We file directly with the county, know their plan-check timelines, and build permit scheduling into every written contract.
Kensington itself has no city-level HOA, but individual neighborhoods and hillside associations may impose design guidelines, particularly for exterior changes visible from public roads. We review these requirements during your free estimate and include any needed documentation in our permit package.
Call (936) 259-2607 anytime. A live person answers 24/7, and we’ll book a site visit where Trevor Nash or one of our background-checked, uniformed technicians will assess your home, explain the county permit path, and deliver a written price before any work starts. Estimates are free, and there’s no obligation.
