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.

Call (830) 251-4560 and we’ll schedule you a confirmed window, not a four-hour gap.
San Francisco chimneys have a specific problem most inspectors in drier cities never see: the marine layer keeps chimney crowns and dampers wet for months at a time. That moisture works into masonry and iron, and what starts as hairline spalling becomes a $1,800 crown repair if it is ignored. We know which Sunset bungalows have original 1920s clay liners, which Noe Valley Edwardians were retrofit in the 1980s, and which Pacific Heights stacks take the worst wind-driven rain off the ocean. That local read is why our Chimney Inspection team does not treat San Francisco like any other market.
Why Flint Chimney Sweep Is San Francisco’s Preferred Chimney Inspection Company
Flint has inspected chimneys across San Francisco since 2002, first as an independent shop and now as part of the Garrison Partners family of independently owned chimney service companies. Homeowners on the west side and in the central neighborhoods keep calling us back because we show up on time, we put every price in writing before a tool comes off the truck, and we hand over camera photos so you can see exactly what we see inside the flue.
Our San Francisco customers consistently tell us the same thing: they have been burned by companies that quote $149 on the phone and show up with a “relining emergency” that costs $6,000. That does not happen with Flint. The 365-Day Done Right Promise means every repair carries a written guarantee valid for one full year, and if a covered repair fails inside that window, we return at no charge. No charge, no argument.
We dispatch background-checked, uniformed technicians to every San Francisco job, from the Outer Sunset to Bayview to the Richmond. A live person answers our phone 24 hours a day, seven days a week. No voicemail trees, no callback forms. When you call (830) 251-4560, you speak to a person who can book your inspection and answer a pricing question without transferring you three times.
Hank Delano leads our inspection operation with a simple rule: the camera does not lie and neither do we. If your chimney needs a sweep and nothing else, that is what we tell you. If it needs a crown coat and a new cap, you will see the photos that prove it before you approve a dollar.
Chimney Flue Inspection in San Francisco
Chimney Flue Inspection in San Francisco is the core of what we do, because the flue is the one part of your chimney you cannot see without specialized equipment. In a fog-heavy city like San Francisco, flue liners crack from water absorption and thermal stress in ways that are invisible from the hearth or the roof. A proper flue inspection runs $249 – $399 here, depending on whether we are running a standard visual check or a full camera scan.
When we inspect a flue in San Francisco, we look for three things beyond the standard creosote check: hairline cracks in the clay liner, rust or seizure at the damper, and moisture intrusion through the crown. Those three issues account for most of what we find in homes built before 1940. We document everything with a camera, and you get the photos in your report whether we flag a problem or not.
Level 1 Inspection
A Level 1 inspection is what most San Francisco homeowners need when they use the fireplace regularly and nothing has changed since the last sweep. We check the accessible portions of the flue, the damper operation, and the firebox condition. It runs $179 – $249 in San Francisco, and it answers the question of whether the chimney is safe to keep using as-is.
Level 2 Camera Inspection
A Level 2 camera inspection is the standard we recommend for any San Francisco home where a chimney has not been inspected in three or more years, or where a property is being bought or sold. We run a high-definition camera from the firebox to the crown and record the entire run. In San Francisco’s damp climate, this is the inspection that catches hairline flue cracks before they become structural repairs. $299 – $449, with written photo documentation included.
Chimney Fire in San Francisco
Chimney Fire in San Francisco is rarer here than in snowy mountain markets, but the risk is not zero and the cause is different than most homeowners assume. San Francisco chimneys do not usually build up the thick third-degree creosote that causes dramatic chimney fires in cold-weather cities. What we see instead is slow-burning creosote mixed with moisture from the fog, which corrodes flue liners and degrades mortar joints. A chimney fire here is more often the result of a cracked liner allowing heat and embers to reach combustible framing than a creosote ignition.
That is why a camera inspection matters more than a basic sweep in San Francisco. You cannot see a cracked flue liner from the firebox, and a sweep with brushes will not fix one. The inspection cost is $299 – $449, and it is the single most direct way to rule out the conditions that allow chimney fires to start. If we find third-degree creosote, our Chimney Inspection in San Francisco protocol includes removal options specific to the liner material in your home.
What a Camera Sees That a Sweep Cannot
A brush sweep clears loose creosote from the flue walls and smoke shelf. It does not reveal cracks, gaps, spalling, or failed mortar joints. In a 1920s San Francisco home with an original clay liner, those hidden defects are the real fire risk. The camera inspection shows us the condition of every foot of the flue, and we walk you through the footage.
When a Chimney Fire Risk Is Urgent
If you smell smoke in rooms that are not near the fireplace, if you hear a rumbling sound while burning, or if you see white staining on exterior brick above the firebox, that warrants an inspection on our next available day. Those signs point to liner failure or moisture damage, not creosote volume. We will not scare you into a relining job; we will show you the camera evidence and give you a written recommendation.
Trusted Brands We Service in San Francisco
Flint works with professional-grade chimney products from Copperfield, DuraFlex, and HeatShield, and we keep common Duraflex service in San Francisco parts in local stock so we are not waiting on a distributor when your crown needs a cap or your damper needs replacing. If your existing chimney includes a Copperfield cap or a DuraFlex liner, our technicians are familiar with the product and the install. What this means for you is faster scheduling and a repair that fits your existing components instead of a one-size-fits-all part we had to order blind.
Common Chimney Inspection Problems We See in San Francisco Homes
- Rusted or seized dampers from year-round Pacific fog. The damper is the iron plate above the firebox that opens and closes the flue. In San Francisco, dampers stick open from rust, which wastes heat and lets cold air pour in all year. A replacement damper is a straightforward fix, but you need an inspection to confirm whether the rust came from the damper itself or from water entry higher up the chimney.
- Spalling chimney crowns misdiagnosed as full rebuilds. The crown is the concrete slab that caps the chimney and sheds water. San Francisco’s marine layer keeps crowns damp, and they begin to spall, flake, and crack after 20 to 40 years. Some companies quote a full chimney rebuild for what a crown coat and new cap would fix. We will show you the difference in the photo report.
- Contractors who skip the camera and sell a sweep when a Level 2 is needed. A basic sweep is the right service for a clean chimney. It is the wrong service for a chimney with hidden liner cracks, moisture damage, or a history of smoking issues. If your fireplace has been drafting poorly or you have never had a camera inspection, a Level 2 is the honest call. We will tell you if a sweep alone is sufficient and put that in writing.
- Water entry through mortar joints on exposed stacks. San Francisco homes with chimneys exposed on three sides, common on the west side and the hill neighborhoods, take wind-driven rain directly into the mortar joints. Repointing and crown sealing are the two most frequent repair recommendations we make here, and both are addressable before they become structural.

FAQs About Chimney Inspection in San Francisco
Yes, especially in San Francisco, because an unused fireplace still has a chimney exposed to fog, rain, and temperature swings that crack crowns and rust dampers. A camera inspection is the only way to see moisture damage inside the flue before it becomes a leak into your walls or ceiling. If you never use the fireplace, we would still recommend a Level 2 every three to five years to check the condition of the structure itself. Call (830) 251-4560 and we will walk you through what the camera will show.
Once a year if you burn regularly, and once every two to three years if the fireplace is rarely used. San Francisco’s damp climate does not reduce the need for inspections, it changes the findings from creosote to moisture damage, and moisture damage progresses whether or not you are burning. An annual inspection catches crown spalling and damper rust early, when the repair is measured in hundreds of dollars instead of thousands.
A Level 2 camera inspection reveals hairline cracks in the flue liner, gaps in mortar joints, hidden water stains, and failed chimney crown conditions that a brush sweep cannot see because the brush only contacts the inner flue wall. In San Francisco, most of what we find on a Level 2 is moisture-related, and none of it would be visible during a standard Level 1. That is why we recommend the camera inspection for any home built before 1980 that has not had one in years. Estimates are free, call (830) 251-4560.
Yes. Third-degree creosote is the hard, glazed tar layer that forms on flue walls, and it does not come off with a standard brush sweep. We have the removal tools and the process for glazed creosote, and we will inspect the liner first to make sure the removal method is safe for your chimney’s material. In San Francisco, third-degree creosote is less common than in cold-weather markets, but it does occur in homes with frequent wood burning and limited airflow.
You should check, not worry. A blocked or cracked flue is a carbon monoxide risk even if the fireplace is rarely used, because the chimney also vents your furnace or water heater in many older San Francisco homes. We test draft and flue condition during every inspection, and if we find a CO concern, we will tell you in plain words and put the recommended fix in writing. Call (830) 251-4560, and we will get an inspector out to confirm whether your flue is venting properly.
