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.
Chimney Company in San Lorenzo, CA
Flint Chimney Sweep handles chimney cleaning, inspection, and repair for homeowners across San Lorenzo, CA. Most of the homes here were built between the 1940s and 1960s, which means clay tile liners and masonry that has now seen sixty to eighty years of Bay Area dampness and wood-burning use. That age profile changes what we look for on every job, and it’s why a San Lorenzo chimney call rarely stops at just sweeping. For a written price before any work begins, call (830) 251-4560.
Why San Lorenzo Homes Are Different
San Lorenzo sits in the Hayward fault zone and gets the full brunt of marine air pushing through the San Francisco Bay. That combination does two things to chimneys. First, the constant moisture cycle settles into mortar joints and accelerates spalling, the flaking and crumbling you see on older brick crowns. Second, many original fireboxes in the area were built without proper dampers or with undersized flue tiles, so creosote builds faster and draft issues are common even in well-maintained fireplaces.
The housing stock matters too. Most San Lorenzo homes are single-story ranchers with interior chimneys that run through the center of the house rather than up an exterior wall. That layout keeps the flue warmer and reduces creosote condensation compared to an exterior chimney, but it also means any water intrusion from a cracked crown or failed flashing spreads into living space before you notice it on the masonry. We see this pattern most often in the neighborhoods off Hesperian Boulevard and along Bockman Road, where the original 1950s construction is still largely intact.
Our Main San Lorenzo Services
Three services cover almost every chimney issue a San Lorenzo homeowner will face, and each has its own dedicated page with local pricing and process details.
Chimney Sweep in San Lorenzo
A standard Chimney Sweep in San Lorenzo removes creosote, soot, and any debris blocking the flue. In San Lorenzo, the creosote profile skews toward the hard, glazed type because of the damp, cool marine air and the older wood-burning stoves still common in the area. That glaze doesn’t brush off, so our sweep jobs here often include mechanical removal with rotary tools. We cover the firebox and surrounding floor, run a camera post-sweep to confirm the flue is clean, and leave you with the written before-and-after documentation.

Chimney Inspection in San Lorenzo
A Chimney Inspection in San Lorenzo is the fastest way to know whether your chimney is safe to light or needs repair work first. Given the age of San Lorenzo’s housing stock, we recommend a camera inspection rather than a visual-only check whenever the chimney hasn’t been looked at in more than two years. Hairline cracks in clay tile liners, failed mortar joints, and hidden water damage are all things only the camera catches, and we show you the footage so you can see exactly what we see.

Chimney Repair in San Lorenzo
Chimney Repair in San Lorenzo covers everything from crown rebuilds and flashing replacement to full flue relining. San Lorenzo’s damp climate makes the crown and top courses of brick the first things to go, and we consistently find that repairs here involve more masonry work than in drier parts of the Bay. Every repair carries our written 365-Day Done Right Promise, and if a covered repair fails within that year, we return at no charge.
