Chimney sweep and repair for Concord’s postwar ranch homes
Original brick chimneys near Todos Santos Plaza, and postwar ranch-style stock filling the tracts built around the Naval Weapons Station.
No commitment either way — we call back and settle on a time that works.
The short answer
Two problems account for most Concord service calls: a flue that hasn’t seen a brush since whoever lived here before last lit a fire, or a low-slope ranch roof whose flashing has finally worn through after enough summers baking in direct sun. Either way, one appointment covers it — we sweep and run a Level 1 or 2 inspection first, then put together a written scope for whatever the camera or a walk on the roof actually turns up, be that repointing a stack near Todos Santos Plaza or a flashing reseal on a ranch home out by Clayton Valley. Concord’s chimney stock skews older than several nearby cities, which is precisely why the crown, mortar and flashing carry most of the workload here.
Local specifics
What is true about Concord
- 01
Concord was founded in 1868 — originally platted as Todos Santos — and grew into the largest city in Contra Costa County, with its historic town square, Todos Santos Plaza, still at the center of the older downtown grid where the oldest brick chimneys stand.
- 02
The Naval Weapons Station Concord, established in 1942, drove a major wave of postwar housing construction as the base’s workforce needed homes nearby; much of that 1950s ranch-style tract stock is still standing today, now well past the original service life of its chimney flashing and crown seal.
- 03
BART reached Concord in 1973, and the city’s downtown transit hub turned surrounding neighborhoods into a dense commuter suburb almost overnight — a wave of infill and condo construction from the 1970s onward that runs alongside the older ranch-home stock rather than replacing it.
- 04
Concord’s summers run hot and dry, commonly well above 90°F for stretches, and that repeated bake-and-cool cycle on an exposed masonry crown is what opens the first hairline crack that autumn’s Diablo winds and winter’s rain then widen.
Housing stock
What the housing stock means for the chimney work
Concord’s older core near Todos Santos Plaza carries brick chimneys dating to the early 20th century, while the bulk of the city — the ranch-style tracts that filled in around the Naval Weapons Station through the 1950s and 1960s — runs low-slope composition roofs with either site-built masonry or factory-built metal chimney systems. That low pitch is the detail that matters most here: it gives standing water and windblown debris more time sitting against a crown or a flashing seam than a steeper roof would, and it is why flashing failure shows up earlier in Concord than in some of its hillier neighbors.

Barbara Rhodes
After a worker cleaned the smoke chamber and swept away baked-on soot from the upper flue walls, the smell of creosote that had been there since the warm summer months was gone.
Norma Peterson
Discolouration on the brick facing led to a deep inspection and sweep, removing concealed creosote pockets behind the lintel, eliminating smoke spilling across the room.
Evan Hughes
Very concerning chimney downdraft caused by strong winds was rectified when the sweep eliminated a substantial soot ring at the crown that had been obstructing the natural exit flow.
Kannon Odom
Our winter parties were about to be ruined by the extreme draft resistance, but a planned sweep found a collapsed inside baffle, cleared the route, and optimized the heat distribution.
Daniel Rodriguez
We cleaned out our wood burning fireplace insert just before winter set in. The airway is wide open, the heat output this season is considerably better.
Questions
What people ask about Concord
Do you serve all of Concord, or just certain neighborhoods?
All of it — Todos Santos, Clayton Valley, Concord Hills, the Monument Corridor and every neighborhood in between sits well inside our twenty-mile radius from central Concord.
My chimney is original to a 1950s Concord ranch home — is that a problem?
Age alone doesn’t settle it. A chimney from that era, masonry or factory-built, often does need crown or flashing work by this point — but we base the actual call on what a real inspection turns up, not just how old the house is.
Does Concord’s hot, dry summer really matter for chimney maintenance?
Yes — repeated heat cycling on an exposed crown opens hairline cracks the same way freeze-thaw does in colder climates. Checking the crown for heat-cracking is a standard part of every Concord sweep visit.
Do I need a permit for chimney repair in Concord?
Repointing or a crown reseal typically doesn’t require one, as long as nothing structural changes. Anything involving a load-bearing element or the building envelope has to go through the City of Concord’s permit process no matter the cost — we’ll say so upfront if that’s where your job lands.
