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 Sunstone Chimney Sweep Is Mission District’s Preferred Chimney Sweep Company
Mission District homeowners call us because we understand what’s behind the plaster on these 1900s – 1920s buildings. Noel Castruita leads the team, and he’s spent years working San Francisco’s attached Victorians, where one chimney serves a unit through shared masonry walls. When a flue fails on a block near Garfield Park, the neighbor’s flue is usually the same age, the same original brick, and the same story waiting to happen. Our Chimney Sweep team doesn’t just run a brush up the flue; we assess the whole system, from cap to firebox, and tell you what can wait and what cannot.
Mission District customers get a direct line, not a dispatch center. We keep our schedule light enough to respect the fact that most people in the Mission don’t have alleys or driveways, so we work around parking permits and narrow service entrances off Bartlett or Shotwell. When you call, you talk to a person who knows this neighborhood. That’s the point.

Chimney Sweep Services in Mission District
Chimney Sweep Services in Mission District start with removing creosote, soot, and whatever the last storm dropped down an uncapped flue, then checking for the failure modes these old buildings are known for. A standard sweep plus Level 1 inspection in Mission District runs $189 – $279. If we’re relining or doing more than a visual check, costs rise from there, and we’ll show you camera footage before recommending anything beyond the basics.
Sweep and Level 1 Inspection
Every sweep includes a Level 1 inspection of the accessible parts of the chimney. We check the cap, crown, flashing, damper, and firebox. On a Mission District Edwardian, that means looking for spalling brick, cracked parging, and rusted caps – the three things we find most often.
Creosote and Soot Removal
Creosote in an unlined 1920s flue doesn’t behave like creosote in a modern stainless liner. It sticks to the rough brick, builds up in the mortar joints, and can ignite at lower temperatures than homeowners expect. We remove it with rotary brushes and inspect the flue surface afterward. Soot removal handles the lighter buildup in gas insert flues that get used for ambience more than heat.
Chimney Cleaning in Mission District
Chimney Cleaning in Mission District is a pre-season job for wood burners and an every-few-years necessity for gas inserts, but the interval depends on what the flue is made of. An unlined original flue serving a gas insert should be checked every year, because the combustion byproducts behave differently than they did in 1920 when these flues were built for coal fires. A standard chimney cleaning runs $189 – $279 in this market, and if the flue needs relining we’ll put a number on it before we start.
Annual Sweep for Active Fireplaces
If you burn wood in the Mission, an annual sweep is the floor, not the ceiling. The fog-shadow microclimate here means less damp than the Sunset or Richmond, but the rainy winters still drive water into crowns and flashing, and water plus creosote makes acid that eats mortar. We sweep, inspect, and tell you what the flue actually looks like inside.
Fireplace Cleaning and Gas Insert Service
Gas inserts don’t produce creosote, but they still leave soot and make-up air debris in the flue, and the original brick flue behind them is often unlined or illegally reused from a wood-burning era. We clean the insert, check the flue, and verify the termination cap is still doing its job above a roof that sees real wind off Twin Peaks.
Trusted Brands We Service in Mission District
We stock and install from professional trade lines – DuraFlex, HeatShield, Copperfield – because these old Mission District systems need materials that match what’s already there, not whatever’s on sale at a hardware store. DuraFlex flexible liners let us fully reline a flue without tearing out the original masonry chimney. HeatShield ceramic resurfacing seals cracked flues that would otherwise be unsafe to use. When a cap rusts out from salt air, we replace it with stainless, not another galvanized unit that’ll fail in five years.

AfterCommon Chimney Sweep Problems We See in Mission District Homes
- Rusted galvanized caps and flashing. Salt air from the bay gets trapped in the Mission’s sheltered microclimate, and it chews through galvanized steel. We replace them with stainless so you’re not back on the roof every few years.
- Unlined or illegally reused 1920s flues. These original brick flues were built for coal smoke, then tapped for gas furnaces and inserts without a liner. They fail Level 2 inspection routinely, and the fix is relining, not another sweep.
- Spalling and loose step-flashing on party walls. Mission District rows share chimneys along continuous masonry walls. When flashing pulls loose between two units, water enters both stacks, and the brick face starts to fail from the top down.
- Creosote in gas-only chimneys. Yes, it happens. When a gas insert vents into an old wood-burning flue, condensation and soot build up in the rough brick, and without an annual clean it becomes a blockage risk.

FAQs About Chimney Sweep in Mission District
Because the original 1920s brick flues were never lined for modern use, and the damage is on the inside where you can’t see it. These flues were built for coal smoke, then re-used for gas furnaces and inserts, and the acidic condensation eats the mortar joints from within. A Level 2 camera inspection shows cracked parging, spalling brick, or gaps in the flue wall. The street view tells you nothing. Call (833) 593-0743 for a camera inspection and we’ll show you exactly what’s inside before quoting any relining work.
Salt air corrodes galvanized steel caps and flashing years before it would inland. The Mission’s sheltered microclimate traps mist and fog near the bay, and exposed metal components on the roof take the brunt of it. We see galvanized caps rusted through in five to eight years where the same part would last fifteen in Walnut Creek. Stainless components are the standard fix.
Water intrusion through deteriorated crowns and pulled-loose step-flashing between attached Victorians. The Mission gets less coastal damp than the fog belt, but when winter rain hits, it finds every gap in the crown and flashing, and freezes and thaws inside the brick. Spalling starts at the top and works down. The fix is a rebuilt crown and new stainless flashing, plus whatever structural repointing the brick needs behind it.
No, but you need one often enough to catch what an unlined flue does with gas byproducts. If your gas insert vents into an original brick flue, soot and condensation build up even without wood fires, and the flue surface is rough enough to hold it. We recommend a check every two years for gas-only inserts, and an annual check if the flue is original and unlined. It’s cheaper to catch a blockage early than to reline after a failure.
Because Mission District chimneys step in a continuous line along shared party walls, and the same builder often ran the same flue up every unit on the row. When one flue fails a Level 2 inspection, the neighbors’ flues are usually the same age, same brick, same lack of liner. We often clean three or four attached chimneys in one visit, and neighbors share the cost of setup and roof access. Call (833) 593-0743 if you want to know whether your row is due.
