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 Alcott Chimney San Francisco Is San Leandro’s Preferred Chimney Sweep Company
San Leandro sits on the Hayward Fault, and that fact shapes how we approach every chimney here. Most companies sweep flues and call it done. We check caps, crowns, and mortar joints for seismic damage first, because in this city, the earthquake risk is real and it shows up in chimneys long before homeowners notice anything wrong inside the house.
Ruben Castellano leads our team, and he set a rule from day one: every technician who walks onto a San Leandro property is background-checked, identity-verified, and announced to you by name and photo before arrival. We call it the Threshold Standard. You’ll see who’s coming and you’ll see their photo ID badge at your door. Every job gets a written price before work begins, and every repair comes with a written guarantee. If a repair fails within 365 days, the second visit is free. That’s the 365-Day Done Right Promise, and it applies to every San Leandro job we complete.
Styles & brands we work with
Chimney Sweep Services in San Leandro
Chimney Sweep Services in San Leandro involve more than brushing soot out of the flue. We remove creosote, the tar-like buildup that causes chimney fires, and we inspect the entire system for damage that’s specific to this area. Given the Hayward Fault and the salt air coming off San Francisco Bay, a sweep here should always include a close look at the cap, crown, and flashing.
Creosote and Soot Removal
We remove creosote at every stage, from flaky first-degree deposits to hardened third-degree glaze. Third-degree creosote is rare in San Leandro because fireplaces here see sporadic use, but when it forms, it’s a serious fire risk that requires chemical treatment or removal with specialized rotary tools.
Chimney Sweep and Fireplace Cleaning
We always lay drop cloths, use HEPA-filtered vacuums, and leave your hearth cleaner than we found it. If you’re in the Estudillo Estates or Broadmoor area with an original masonry fireplace, expect us to spend extra time on the smoke shelf and damper housing, where debris accumulates in older builds.
A routine sweep in San Leandro runs $189 – $289. If you add a Level 1 inspection, which we recommend every year here, it’s $149 – $199. Call (831) 534-3789 and you’ll get an exact written quote before we book anything.

Chimney Cleaning in San Leandro
Chimney Cleaning in San Leandro means different things depending on the age of your home and how close you are to the Bay. For pre-war bungalows and mid-century ranches with brick or stone chimneys, cleaning usually includes removing bird nests, debris, and deteriorated mortar that’s fallen into the flue. For newer construction with prefab metal flues, it’s often a straightforward soot and creosote removal, plus a check of the chimney termination.
Annual Sweep
Even if you rarely light a fire, an annual sweep matters in San Leandro because idle chimneys attract nesting birds and collect debris. Last winter, we pulled a full bird’s nest out of a flue in a home near Estudillo Estates, and the homeowner had no idea it was there. A sweep is cheap insurance compared to a chimney fire or carbon monoxide backup.
Fireplace Cleaning
We clean the firebox, grate, glass doors, and surrounding hearth. Salt air near the Bay corrodes metal firebox components faster than inland, so if your damper is sticking or your glass looks foggy, we’ll tell you and show you photos before recommending anything.
Chimney cleaning in San Leandro runs $189 – $289, and fireplace glass and firebox cleaning are included in that range. You’ll get a written price before any work starts.
Trusted Brands We Service in San Leandro

When we replace a cap or crown in San Leandro, we install stainless steel, period. Copperfield and Gelco products round out the lineup where the job calls for them.

AfterCommon Chimney Sweep Problems We See in San Leandro Homes
- Cracked clay tile liners from seismic movement. Older homes in Estudillo Estates and Broadmoor often have original clay tile liners that crack over time. Even minor earthquakes are enough to open a vertical crack, and once that happens, heat and gases can reach combustible framing.
- Corroded caps and flashing from Bay salt air. Homes within a few miles of the shore get more salt exposure than people realize. Galvanized caps rust through in a few seasons and let rain in, which accelerates every other problem.
- Bird and debris blockages after long idle periods. Fireplaces in San Leandro are used sporadically, so in spring and summer, birds build nests in uncapped flues. A blocked flue pushes smoke and carbon monoxide back into the house.
- Missing or cracked mortar crowns from earthquake shifts. Even a small quake on the Hayward Fault can dislodge a crown that was perfectly fine the year before. This is why we look at the top of the chimney first on every San Leandro job.

FAQs About Chimney Sweep in San Leandro
Every year, even if you never light a fire. San Leandro sits on the Hayward Fault, and seismic shifts cause damage to chimneys that has nothing to do with creosote or usage. A Level 1 inspection costs $149 – $199 and tells you whether your flue is still safe. Call (831) 534-3789 to book one; we’ll send you the inspector’s name and photo before they arrive.
Yes. San Leandro is close enough to San Francisco Bay for salt air to corrode galvanized steel caps within a few seasons. We install stainless steel caps exclusively here, usually Olympia Chimney or Famco, because they hold up to the coastal conditions far longer. Inland cities don’t face the same corrosion problem.
Cracked clay tile liners from seismic movement. In the Broadmoor neighborhood, our tech found a 1930s-era clay tile liner with a vertical crack running through the flue, likely from decades of minor seismic movement. We relined it with HeatShield and installed a new stainless steel cap to keep salt air and rain out. The homeowner had last used the fireplace three winters ago, right after a small quake. That’s the pattern in this city.
They can. San Leandro’s older homes, many built in the 1920s through 1950s with masonry chimneys, fall under BAAQMD rules that sometimes require upgrades like caps or dampers during a sweep. If your chimney isn’t compliant, we’ll tell you specifically what’s needed and give you a written quote before any additional work begins.
Third-degree creosote is hardened, tar-like creosote that’s concentrated fuel inside your flue, and it’s the most dangerous form for chimney fires. It’s less common in San Leandro than in cold climates because fireplaces here are used sporadically. But if you’ve burned a lot of unseasoned wood or your flue hasn’t been cleaned in years, it can form, and we have the tools to remove it safely. Call (831) 534-3789 for a free estimate.
