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 Emberly Chimney Cleaners Is San Lorenzo’s Preferred Fireplace Services Company
We’re the company that puts a camera down every flue before we recommend anything. That’s the Fireplace Services standard Corrine Halstead set when she founded this company in 2009: NFPA 211 Level 2 inspection, photo record, written price, written warranty. Every single visit. Homeowners in San Lorenzo have come to expect that from us because the neighborhood’s housing stock is so uniform. When you’ve inspected a few hundred Bohannon-era ranch chimneys between Via Alamitos and Hesperian Boulevard, you learn the failure points before you even set up the ladder.
Our techs know San Lorenzo. They know these original 1950s clay tile liners crack in the same places. They know the cast-iron dampers seize from bay moisture. They know Alameda County rules apply here, not a city fire code. That local knowledge means we quote accurately the first time, and when we send a background-checked, uniformed technician to your home, that person has seen your exact fireplace a dozen times before.
And every job carries our 365-Day Done Right Promise. If something isn’t right after we leave, we come back and make it right. That’s Clause 1 of the Haven Standard: written scope, written price, written warranty, in your hands before work begins.
Our Fireplace Services in San Lorenzo
Gas Fireplace Service
Gas fireplace service in San Lorenzo runs $185-$295 for a full inspection, cleaning, and pilot assembly check. The marine layer here means gas units accumulate soot and mineral buildup faster than inland units, and we regularly find thermopiles coated in residue that causes intermittent starts. We stock replacement thermocouples, thermopiles, and log sets for the brands most common in this area, so most repairs finish same-day.
Wood Burning Fireplace
A wood burning fireplace that hasn’t been used in months is a San Lorenzo specialty. Hardened first-degree creosote bakes into glaze when fired after long idle stretches, and that requires more than a standard brush. Our cleaning starts at $195 and includes a full Level 2 camera scan. We document everything: flue condition, creosote class, smoke chamber integrity. You get photos, not a shrug.
Fireplace Insert
Many San Lorenzo homeowners install inserts to convert drafty original fireplaces into real heat sources. Insert installation runs $1,850-$4,200, including the liner and electrical. We see a lot of Bay Area homes where inserts were installed without proper insulation around the liner, and we fix those heat-loss problems while bringing the unit up to current Alameda County requirements.
Damper Repair
Damper repair in San Lorenzo ranges from $275 for a standard replacement up to $650 for a top-sealing model installed on the chimney crown. The original cast-iron dampers in these 60-to-80-year-old ranches rust from persistent coastal moisture, and many have been seized shut for decades. We replace them with stainless steel or top-sealing dampers that actually close tightly and keep marine air out of the flue.
BeforeAfterTrusted Brands We Service in San Lorenzo
We install and service components from Famco, Copperfield, and HeatShield, and we stock San Lorenzo-specific parts at our Bay Area dispatch hub. That matters when your 1954 fireplace needs a specific damper size or a particular stainless cap. No waiting a week for a part to ship from out of state. When Corrine Halstead set up the Haven Standard, she insisted on buying through the Haven buying network specifically to keep customer prices honest. You’ll see those brands on your written quote, with pricing upfront.
Common Fireplace Problems We See in San Lorenzo Homes
- Corroded galvanized chimney caps. Salt air and persistent marine moisture eat galvanized caps within 5 to 8 years. Once the cap fails, rain gets in, and rain in a San Lorenzo winter means cracked liners and rusted dampers. We replace with stainless steel, which is the only material that makes sense this close to the bay.
- Cracked clay tile liners from the 1940s through 1960s. These original liners crack under repeated heating-cooling cycles even without heavy use, because the damp coastal air keeps the masonry saturated. We find this on nearly every Bohannon-era fireplace we inspect.
- Seized and rusted cast-iron dampers. If you haven’t opened your damper in years, there’s a good chance it won’t move now. The rust seizes the pivot points. A replacement damper restores draft and stops cold air and moisture from dropping into the firebox.
- Glazed creosote from long-idle fireplaces. When a San Lorenzo fireplace sits unused through the damp season, then gets fired up in November, the creosote inside hardens into a tar-like coating. That class of creosote is the kind that feeds chimney fires. Our camera scan identifies it before we recommend how to remove it.

FAQs - Fireplace Services in San Lorenzo
Most fireplace repairs in unincorporated San Lorenzo, including damper replacement, cap installation, and firebox parging, do not require a county permit. Full chimney rebuilds or structural work generally do. Because San Lorenzo is unincorporated Alameda County, not a city, the rules come from county code, not a municipal fire department. Our techs check current county requirements before any structural work. Call (980) 580-8641 and we’ll tell you what applies to your specific home before you commit to anything.
Spare the Air alerts, issued by the Bay Area Air Quality Management District, ban wood burning in San Lorenzo on designated winter days when air quality is poor. It’s not a suggestion. Alameda County residents are subject to these rules, and fines apply. Our techs will tell you how to check before you burn, and we can also service gas inserts for homeowners who’d rather not roll the dice on winter air-quality days. Give us a call and we’ll walk you through the seasonal schedule.
Galvanized steel corrodes in San Lorenzo because the marine layer brings year-round ambient salt and moisture. On a late-1940s or 1950s ranch, the original cap has usually been through decades of that exposure, and replacement galvanized caps from a big-box store fail again in 5 to 8 years. We install stainless steel caps because they’re the only material that holds up against bay air. The difference in cost is modest, but the lifespan difference is measured in decades. Call for a quote and we’ll show you what your current cap looks like on camera.
In most cases, a rusted cast-iron damper from a 1960s San Lorenzo fireplace needs replacement, not repair. The rust seizes the pivot mechanism, and even if you free it, the metal is pitted enough that it won’t seal tightly. That lets cold air and moisture drop through your flue all year. We replace with top-sealing dampers that mount on the chimney crown, which seals far better than any original throat damper. Replacement runs $275-$650 in San Lorenzo. Call (980) 580-8641 and we’ll tell you what your camera scan shows before you decide.
Yes, it’s a well-documented problem in San Lorenzo’s climate. When a fireplace sits unused through damp coastal winters, the creosote inside doesn’t dry out. It hardens and concentrates. When you finally light a fire, that hardened first-degree creosote can bake into a glaze that feeds chimney fires. We classify creosote by degree during our inspection, and our written quote tells you exactly which class you’re dealing with. Most San Lorenzo cleanings we do fall into Class I or Class II, with Class II requiring rotary tools, not just a brush. Call us for a camera scan and we’ll show you exactly what’s in your flue.
