Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterChimney Company in Kensington, CA
Chimney cleaning in Kensington, CA typically runs $189 – $299 for a standard sweep, and most homes in this hillside community are better served by an inspection-plus-sweep package because of how fires burn here. Kensington’s older housing stock, steep lots, and cool, damp winters create specific creosote and moisture conditions that flatland chimneys don’t see. We’re Flint Chimney Sweep, part of the Garrison Partners family founded in 2002. Every job gets a written price before work starts. Call (830) 251-4560 and a live person answers.
Why Kensington Homes Are Different
Kensington sits on the eastern slope of the Berkeley Hills, and that terrain shapes chimney work in ways that don’t apply in the flats. Many homes along Arlington Avenue, Coventry Road, and the streets branching off Colusa Avenue were built between the 1920s and 1950s, which means clay tile liners, masonry that has shifted with the hillside, and chimneys that catch more wind than houses down the hill. Wind-driven rain is a real factor here. It finds its way into cracked crowns and worn flashing faster than in sheltered neighborhoods.
The microclimate matters too. Kensington gets more overnight fog and damp air than inland areas, which means creosote inside a flue absorbs moisture and turns more corrosive. A chimney that would pass a visual check in a drier climate often needs the liner looked at here. The terrain also complicates rooftop access. Steep driveways and tight setbacks on hillside lots mean our technicians plan roof access carefully before the truck even parks. And because Kensington is unincorporated Contra Costa County rather than a city with its own building department, permit requirements flow through the county. We handle that paperwork when a repair requires it, so homeowners don’t have to sort it out themselves.
Our Main Kensington Services
Kensington homeowners call us most about two things: annual sweeps before burning season and inspections after buying or selling a hillside home. Repairs follow when those inspections turn up something.
Chimney Sweep in Kensington
A chimney sweep in Kensington removes the creosote and soot that build up inside the flue during a burning season. In this climate, the creosote is often harder and more concentrated than what flatland chimneys produce, because Kensington fires burn cooler and damper. We use rotary brushes and HEPA-filtered vacuums to keep the dust contained inside your home, and every sweep includes a visual check of the flue, cap, and firebox. The process takes about an hour and a half, and we leave the hearth area cleaner than we found it. Details on what’s included are on the Chimney Sweep in Kensington page.
Chimney Inspection in Kensington
A chimney inspection in Kensington is a camera-based look at the full interior of the flue, the smoke chamber, and the exterior masonry. Hillside shifting, damp air, and older clay liners mean we recommend a Level 2 inspection more often here than in newer subdivisions. The camera shows exactly what the liner looks like inside, and you see the photos before anyone talks about repairs. We never recommend work without visual evidence you can review yourself. What each inspection level covers, and when a Level 2 is required, is outlined on the Chimney Inspection in Kensington page.
Chimney Repair in Kensington
Chimney repair in Kensington covers flue relining, crown repair, masonry work, and replacing damaged caps or flashing. The two repairs we see most on Kensington homes are cracked crowns that let water into the masonry, and deteriorating clay liners that no longer contain heat and smoke the way they should. Every repair we make carries our 365-Day Done Right Promise: a written guarantee valid for one full year, with a free return visit if a covered repair fails. The Chimney Repair in Kensington page lists what each repair involves and what it costs.
