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.

Why Flint Chimney Sweep Is San Lorenzo’s Preferred Chimney Inspection Company
Homeowners in San Lorenzo call us because the process is documented before work begins. We’re part of the Garrison Partners family, founded in 2002, and every location operates under the same code: The Garrison Standard. That means a written price before any work starts, every time. A technician who is background-checked and uniformed, so you know exactly who is walking through the door. And a 365-Day Done Right Promise that puts the guarantee in writing on every repair for one full year. If a covered repair fails in that window, we return at no charge. No argument, no re-quote.
We know San Lorenzo’s housing stock: mid-century ranches, two-story homes off Bockman Road, and plenty of original masonry chimneys that have been through decades of Bay Area weather. That local familiarity matters. It means we look for what actually fails here, not what a generic checklist says to check. Our scheduling dispatch is coordinated from the San Francisco Bay Area office, but our crews serve San Lorenzo directly and understand this specific climate and building mix. You can read more about how we approach the whole process on our Chimney Inspection hub page, or see how we serve the area on the San Lorenzo page.
Chimney Camera Inspection in San Lorenzo
Chimney Camera Inspection in San Lorenzo is the difference between guessing and knowing. A Level 1 inspection is visual: what we can see from the hearth and the roof. But a chimney that’s original to a 1960s San Lorenzo home hides a lot behind brick. We run a high-resolution camera from the firebox up through the smoke chamber and flue liner, and we watch the footage right there with you on a tablet. You see what we see. That’s the point.
What the camera actually shows
The camera catches what a visual check misses: hairline cracks in clay tile liners, separated flue joints, creosote accumulation behind the damper, and moisture streaking inside the flue. In San Lorenzo, the marine layer means we see moisture issues more often than heavy creosote buildup. The camera confirms it instead of us asking you to take our word for it.
When you need it
If your home has been through an earthquake, a reroof, or a prior liner repair, a camera inspection is the only way to verify the smoke chamber and liner joints are intact. If you’re buying a home in San Lorenzo, this is the inspection level we recommend. You get a photo report documenting every finding, so the information doesn’t disappear after the truck leaves.
Fireplace Inspection in San Lorenzo
Fireplace Inspection in San Lorenzo means checking the entire system, not just the firebox. We inspect the damper, smoke shelf, smoke chamber, flue liner, chimney cap, crown, flashing, and the mortar joints throughout the chimney structure. Each piece matters. A damper that doesn’t seal leaks conditioned air year-round. A cracked crown lets winter rain in every single season, and that water reaches the liner before you notice anything on the ceiling.
What gets checked at the roof
A lot of companies skip the rooftop portion if the homeowner hasn’t burned in years. We won’t. San Lorenzo’s winter rain and summer fog attack chimney crowns and flashing from the outside. Crown spalling, rusted caps, and separated flashing are the most common problems we find here, and they happen whether or not you use the fireplace. We walk the roof, photograph everything, and show you the condition.
What happens after the report
You get a written inspection report with photos and a straight recommendation. If work can safely wait, we tell you that in plain words and identify what we’d watch. If a repair is needed, you get a written price before anything is scheduled. No pressure, no “today only” pitch. That’s the only way we operate.
Trusted Brands We Service in San Lorenzo
When a San Lorenzo inspection turns up a failing component, the fix should use materials we can name and you can verify. We work with professional-grade chimney trade brands including DuraFlex, Olympia Chimney, and Famco. A DuraFlex liner install or an Olympia Chimney cap replacement is specified by what the job actually needs, not by what’s easiest to stock. For San Lorenzo customers, we keep common parts available through our Bay Area dispatch, which means less waiting between inspection and repair. If the finding is a rusted cap or a cracked flue tile, the written quote we give you names the exact material we’ll use. You can look it up before you say yes.
Common Chimney Inspection Problems We See in San Lorenzo Homes
Here is what actually shows up in San Lorenzo inspections:
- Water intrusion through crown and flashing. San Lorenzo’s winter rain and summer fog drive the most common failure we document. Crown cracks and flashing gaps let water in regardless of whether the fireplace is used. By the time staining appears on the ceiling, the liner has often been wet for months.
- Rusted or loose chimney caps. The marine air accelerates rust on cheap caps. A loose cap lets rain straight down the flue and invites birds and debris. We see this frequently on original caps from the 1970s and 80s.
- Deteriorated mortar joints in older masonry. Many San Lorenzo homes were built with exposed brick chimneys. Decades of wet-dry cycles break down the mortar, and spalling brick falls inside the flue. This narrows the passage and creates draft problems.
- Unseen liner cracks after seismic activity. The Hayward Fault runs close enough that San Lorenzo homes feel real shaking. A minor quake can crack a clay tile liner without any visible sign from the exterior. Camera inspection is the only way to verify.

If you are buying a home and the inspector recommends a chimney check, most San Lorenzo real estate transactions use Level 2 as the standard.

FAQs About Chimney Inspection in San Lorenzo
Every year, even if you rarely burn. The reasoning is simple in San Lorenzo: the marine layer, fog, and winter rain damage your chimney from the outside regardless of how often the fireplace is lit. Crown cracking, flashing failure, and cap rust progress year after year whether the flue is hot or cold. A chimney that doesn’t get used still accumulates moisture damage, nesting debris, and sometimes hidden structural shifts after seismic events. Annual inspection catches external deterioration before it reaches the liner. Call (830) 251-4560 to schedule one, and the written price comes to you before we arrive.
A standard visit covers the firebox, damper, smoke chamber, flue, cap, crown, flashing, and exterior masonry. We check the accessible portions visually, and if a Level 2 is warranted, we run the camera through the entire flue and show you the footage on a tablet. You receive a written photo report before we leave. The whole appointment takes about an hour on average. We document everything, and if a repair is needed, we tell you whether it is urgent or can wait, then provide a written quote. No inspection finding gets repaired without your explicit approval on a separate written price.
It is a structural and water-management problem, not cosmetic. A cracked crown or failed flashing is the number one route for water to enter a San Lorenzo chimney. Rain runs into the crack, migrates down the masonry, dissolves mortar, and eventually reaches the liner and even the ceiling structure. Left alone, a $400 flashing repair becomes a $3,000+ crown rebuild plus interior water damage. If our inspection finds crown or flashing defects, you get photos and a written price for the fix. Call (830) 251-4560 for the exact scope and number.
Creosote is rated in three degrees: first-degree is a flaky soot, second-degree is a hard, shiny tar-like glaze, and third-degree is a dense, hardened glaze that resists normal sweeping. In San Lorenzo, heavy creosote is less common than in wood-burning-heavy inland cities because of the marine climate and intermittent use. But even light creosote combined with water intrusion creates an acidic slurry that accelerates liner deterioration. Our inspection reports note the degree we find, and if it reaches second or third degree, we recommend removal before further burning.
No. We do not recommend a liner replacement without camera evidence you can see on the tablet yourself. If we find hairline cracking that doesn’t yet compromise drafting or safety, we tell you it can wait and document it for future comparison. If we do recommend a liner repair or replacement, the report includes the images and a written quote with the specific material, usually HeatShield or DuraFlex. You decide. No pressure, and no ‘the sky is falling’ pitch. Call (830) 251-4560 and we will walk you through what we found in plain English.
