Frequently Asked Questions - Chimney Cleaning in San Francisco, CA
We've swept chimneys across San Francisco since 1984, from Victorians in Noe Valley to the hillside homes of Visitacion Valley. Here are the questions we answer most often on the phone.
Pricing & Cost FAQs
A standard chimney sweep and Level-1 inspection in San Francisco runs $189-$289 for most single-flue systems. Two-story homes in Pacific Heights or hillside properties in Bernal Heights sometimes run $320-$380 because of roof access complexity. We give you the full price before we start. No surprises on the bill.
Our standard sweep includes the rotary cleaning of the flue, a visual inspection of the firebox, damper, and smoke chamber, and a written condition report with photos. If we find creosote buildup beyond Stage 1, we'll show you and explain what it means. The Keystone Standard applies: 90 days, in writing, no arguing.
We don't add parking fees for standard appointments in San Francisco, Mission District, or Noe Valley. If your building requires HOA scheduling or specific access windows, we work with that. Commercial properties in Chinatown or Emeryville sometimes need coordination with building management, but we don't charge extra for the phone calls.
Gas fireplace service typically costs less, around $149-$219, because there's no creosote removal. But gas systems still need inspection of the burner, logs, and venting. We've found blocked vents in South San Francisco condos that were serious carbon monoxide risks. The savings aren't worth skipping the check.
We offer a 10% discount for homeowners 65 and older in San Francisco, Daly City, and Alameda. We've served this generation for forty years. They call, they don't click, and they deserve a square deal. Mention it when you schedule.
Service & Process FAQs
Most residential sweeps take 45 minutes to 90 minutes. A Level-2 camera inspection adds 30-45 minutes. We don't rush. The 400th job gets the care of the first. We'll tell you when we arrive how long we expect to be in your home.
We run a high-resolution camera up the full length of your flue, documenting every crack, joint, and deposit. You see the footage. We explain what we're seeing in plain English. Every inspection ends with photos you can see and a plain-English verdict. This is standard for home sales in Oakland and Tiburon, and for any chimney that hasn't been serviced in three-plus years.

The National Fire Protection Association recommends annual inspection, with cleaning as needed. In San Francisco's damp climate, we see accelerated mortar deterioration and rusted dampers, especially in fog belt neighborhoods like the Sunset and Richmond. If you burn wood regularly, clean every year. Occasional users can sometimes go two years, but we still want to look.
We lay down floor protection, use HEPA vacuums, and seal the fireplace opening before we start. We've worked in restored Victorians in Alameda and modern condos in Emeryville. Your home first: we work in your house the way we'd work in our mother's. If we leave a speck, call us back.
Creosote is a tar-like residue from burning wood. Stage 1 brushes off. Stage 2 needs rotary tools. Stage 3 is glazed and highly flammable. San Francisco's cool, moist air promotes Stage 2 and 3 buildup because fires don't burn as hot. We've removed glazed creosote from chimneys in Sausalito that hadn't been cleaned in a decade. It's a real fire hazard.
Brands & Parts FAQs
We install Gelco and Olympia Chimney caps for most residential applications. Gelco's stainless models hold up well in San Francisco's salt air, especially for homes in Tiburon and Sausalito with bay exposure. Olympia Chimney's multi-flue caps work well for the larger fireplaces common in pre-war Oakland homes. We measure on site and fabricate custom when needed.
We stock Famco dampers and Copperfield chimney liners for common repair scenarios. Famco's top-sealing dampers solve draft problems we see in Noe Valley's tall chimney flues. Copperfield's stainless liners carry a lifetime warranty when we install them. We don't guess on parts. We diagnose, then specify.
We source brick and mortar to match San Francisco's common styles: soft-mud Victorian bricks, pressed brick from the 1920s, and the salmon-colored brick found in Visitacion Valley and Daly City. Masonry repair by people who actually know mortar. We don't slap on gray caulk and call it done.
Licensing & Insurance FAQs
We're state-licensed chimney contractors, carry San Francisco business registration, and maintain full general liability and workers' compensation insurance. We've been sweeping chimneys in this city since 1984. A company that plans to be in town in thirty years acts like it. Ask any competitor how long they've been here.
Our sweeps are CSIA-certified (Chimney Safety Institute of America) and trained through our apprentice-to-journeyman program. Krafted right: trained journeymen, proper materials, no shortcuts. We don't send a kid with a brush. We send someone who can explain what they found and why it matters.
Structural repairs, liner installations, and rebuilds require permits in San Francisco, Oakland, and most Bay Area jurisdictions. We pull permits, schedule inspections, and meet the inspector. You don't chase paperwork. Standing behind it means handling the boring parts too.
Emergency & Response FAQs
We offer same-day response for smoking chimneys, suspected blockages, and post-fire damage in San Francisco, South San Francisco, and Daly City. For Sausalito, Tiburon, and the East Bay, we typically schedule next-day. Call (855) 408-5567. We'll tell you honestly if it's safe to use your fireplace tonight or if it needs to stay cold.
Smoke backing up into the house, visible flames outside the firebox, a fallen liner, or strong gas odors. After earthquakes, which San Francisco knows too well, we check for shifted flue tiles and compromised chimney crowns. Don't use a chimney you suspect is damaged. Carbon monoxide and structural collapse are real risks.
We work in San Francisco weather. Light rain doesn't stop a sweep. Heavy rain or high wind delays roof work for safety. We'll be there when we say, or we'll call you early if conditions shift. We've rescheduled Tiburon appointments when Marin fog made ridge access unsafe. No one gets hurt chasing a schedule.
Warranty & Guarantees FAQs
The Keystone Standard: 90 days, in writing, no arguing. If we cleaned it and something we should have caught shows up within 90 days, we come back. No paperwork battle. No "read the fine print." Standing behind it is one of our K.E.Y.S. values, and we mean it.
Chimney liner installations carry the manufacturer's lifetime warranty plus our 5-year workmanship guarantee. Caps and dampers carry 2-year installation warranties. We document every job with photos and a written report. If it's not right, we come back. No paperwork, no arguing.
Call us. We'll return. The hearthstone is the stone the whole home gathered around, and we treat your home with that weight. We've been in San Francisco since 1984 because we keep our word. Your home first. Every time. That's not a slogan. It's how we stay in business.
