Why Kensington Homes Are Different
Kensington sits on the eastern slope of the Berkeley Hills, which means two things for any remodel: drainage matters more than most homeowners expect, and access is rarely a straight shot from the street. Homes here were largely built between the 1920s and 1960s, so we regularly open walls to find knob-and-tube wiring, dimensional lumber that is actually dimensional, and foundation piers cut into hillside rock. On Colusa Circle and along Arlington Avenue, many homes step down their lots in two or three levels. That changes how we stage materials, how we brace openings, and how we route new plumbing. Kensington is unincorporated Contra Costa County, not part of Berkeley’s building department. Permits go through the county, which means plan review timelines and inspection scheduling follow county rhythms. None of this is a problem if it is priced in from the start. It is a problem when a contractor discovers it mid-project and hands you a change order.
Fog and marine air push in from the bay most mornings. Wood-framed homes here deal with real moisture exposure, so exterior work, window replacement, and any bathroom remodel need flashing and ventilation details done correctly the first time. A bathroom exhaust fan that vents into the attic is a mold claim waiting to happen in this climate.
Styles & brands we work with
Our Main Kensington Services
Most Kensington homeowners call us for one of three reasons: a general contractor to manage a larger project, a bathroom that needs a full remodel, or a whole-home update that touches multiple rooms at once.
General Contractor in Kensington
As a General Contractor in Kensington, we handle the parts of a project homeowners should not have to think about: pulling county permits, scheduling inspections, coordinating subcontractors, and keeping the job moving when a hillside lot complicates material delivery. Kensington projects often involve retaining walls, drainage corrections, and structural work alongside the visible finishes. We deliver a written price for the full scope before tools arrive, and every crew member is background-checked, uniformed, and introduced by name and photo before the visit.
Bathroom Remodeling in Kensington
Kensington bathrooms in 1930s and 1940s homes are often small, with cast-iron tubs, single-sill windows, and plaster walls that hide decades of previous patches. A Bathroom Remodeling in Kensington typically involves reworking the footprint, replacing galvanized supply lines, adding proper ventilation, and waterproofing to modern code. With our 365-Day Done Right Promise, if anything is not right within a year of completion, we return and make it right at no cost. That matters on a hillside home where a slow leak can go unnoticed for months.
Home Remodeling in Kensington
A Home Remodeling in Kensington project might mean opening up a kitchen, adding a bedroom, or converting an underused lower level. Kensington homes have floor plans that worked for 1950 but rarely match how families live now. We handle the structural, electrical, plumbing, and finish work as one coordinated scope with one written price. No verbal estimates that grow on the final bill. The Threshold Group standard applies on every job: identity-verified crews, photo badges at the door, and a written guarantee on every completed project.

FAQs About Remodeling Company in Kensington
Most Kensington projects begin with a site visit and a written estimate within about a week. Permitting through Contra Costa County then sets the pace: simple bathroom remodels can clear in a few weeks, while additions and structural work take longer. Call (803) 680-2547 and we will give you an honest timeline for your specific project.
Yes. Kensington falls under Contra Costa County jurisdiction, and we pull all required permits, schedule inspections, and walk the job through final sign-off. The permit process here is not a mystery, just a checklist. We handle it so you do not spend afternoons on hold with the county.
No, not unless you change the scope. The written price you receive before demolition is the price you pay, and any change you request gets its own written approval before we proceed. No surprise invoices at the end. Call (803) 680-2547 for a free, no-pressure estimate.
