Frequently Asked Questions - Chimney Cleaning in San Francisco, CA
We've been sweeping chimneys across San Francisco since 2014. Here are the questions we hear most often, answered plain and direct.
Pricing & Cost FAQs
A standard chimney sweep in San Francisco typically runs between $180 and $320 for a single flue in good working order. Two-story homes in Noe Valley or homes with steep roof access in Visitacion Valley sometimes edge toward the higher end. We give you a written estimate before we start, so there's no surprises on the bill. Call (855) 408-5567 for an exact quote - estimates are free.
Heavy creosote buildup, multiple flues, and birds' nests or blockages all add time and cost. In San Francisco's Mission District, we see more nesting issues from the mild coastal climate that keeps animals active year-round. A level-2 camera inspection, which we recommend for any home changing hands or after a chimney fire, runs additional. We'll tell you upfront if your job needs more than a standard sweep.
DIY chimney cleaning kits cost less upfront, but most San Francisco homeowners end up calling us after. Without a camera inspection, you can't see cracked flue tiles or hidden creosote glazing deep in the system. More importantly, roof work on San Francisco's pitched Victorian roofs is genuinely dangerous. We don't recommend it. Every pro working under our name is required to hold the license and insurance their state requires, and we document everything with photos you can see.
We serve Daly City, South San Francisco, and the broader Bay Area from our San Francisco branch. Travel within our standard service area is built into our pricing. For Sausalito, Tiburon, or across the bridge to Oakland and Alameda, we'll note any travel adjustment when you call. Call (855) 408-5567 and we'll give you the exact number - estimates are free.
No. We don't believe in them. Our written estimate lists every charge before we touch a tool. If we find something unexpected - a damaged damper, a missing chimney cap - we stop, show you photos, and explain your options. No pressure, no surprise add-ons. That's a square deal, and it's how we've worked since 2014.
Service & Process FAQs
We lay protective covers, run brushes the full length of your flue to remove soot and creosote, and vacuum the firebox and smoke shelf. Then we inspect with a camera, looking for cracks, gaps, or deterioration you can't spot from the hearth. In San Francisco's older housing stock - think Victorians in Noe Valley or the compact flues in Chinatown - we often find previous repairs that need a closer look. You get photos and a plain-English verdict before we leave.
Most standard sweeps take 45 minutes to 90 minutes from arrival to cleanup. A level-2 camera inspection adds 30 to 45 minutes. Homes in San Francisco with multiple fireplaces, or properties in the Mission District with complex venting for historic stoves, may run longer. We'll tell you when we schedule so you can plan your day.
The National Fire Protection Association recommends annual inspection, with cleaning as needed. In San Francisco, where many homeowners burn sparingly due to mild winters, every one to two years is common for light use. If you burn more than three cords of wood a season, or if you notice smoky odors or draft issues, schedule sooner. The coastal moisture here can also accelerate mortar deterioration, so an annual look is wise.
A level-2 inspection includes everything in a standard sweep plus a camera scan of the full flue interior and accessible portions of the chimney structure. You need one when buying or selling a home, after a chimney fire or lightning strike, or if you're changing appliances or fuel types. In San Francisco's competitive real estate market, we perform dozens of these each month for buyers in Noe Valley, Visitacion Valley, and across the city who want documented condition before close.
Not when it's done right. We use industrial vacuums with HEPA filtration, lay drop cloths from the door to the hearth, and seal the firebox before brushing. Our K.E.Y.S. value of Your home first means we work in your house the way we'd work in our mother's. We've been doing this since 2014, and we know how to leave a home cleaner than we found it.
Brands & Parts FAQs
We use Gelco and Olympia Chimney caps for most San Francisco installations - both hold up well against the salt air coming off the Bay. For liner work and repair components, we source from Famco and Copperfield, depending on the flue size and fuel type. We don't install whatever's cheapest; we install what fits your system and will last. Every time - the 400th job gets the care of the first.
We can usually source compatible components for San Francisco's historic housing stock. Custom copper caps or ornate shrouds for Victorians in Noe Valley sometimes require specialty fabrication, which we coordinate with local metalworkers. We show you options and pricing before ordering anything. No surprises on the bill.
We focus on installation and repair of functional components - caps, dampers, liners, sealing systems. For decorative screens or tool sets, we can recommend San Francisco retailers we've worked with over the years. Our expertise is in what keeps your chimney safe and drafting properly, not in retail markup.
Licensing & Insurance FAQs
Every pro working under our name is required to hold the license and insurance their state requires, and our sweeps train to CSIA (Chimney Safety Institute of America) standards. Since 2014, we've believed in documenting like an engineer and working like a craftsman. That means photos you can see, a plain-English verdict, and no paperwork games.
Yes. We're fully insured for residential chimney work throughout San Francisco, Daly City, Oakland, and our full Bay Area service area. If you'd like to verify coverage, call (855) 408-5567 and our live coordinator can connect you with the details you need. We've been a fixture in this community too long to cut corners on protection.
Most chimney repairs and cleanings don't require permits, but structural work, liner replacements, or exterior masonry rebuilds often do. San Francisco's Department of Building Inspection has specific requirements for historic districts and seismic retrofit zones. We know the local code and pull permits when needed, included in our project pricing. We'll tell you upfront if your job requires city approval.
Emergency & Response FAQs
We offer same-day service when our schedule allows, Monday through Saturday during our operating hours: 7:30 AM to 8:00 PM weekdays, 8:00 AM to 7:30 PM weekends. We don't promise 24/7 availability - we promise we'll be there when we say. For suspected chimney fires, carbon monoxide concerns, or sudden blockages, call (855) 408-5567 and our live coordinator will find you the earliest opening.
A chimney fire - often signaled by loud cracking, dense smoke, or a hot, roaring sound - is an emergency. Call 911 first, then call us for inspection before using the fireplace again. Sudden carbon monoxide detector alarms, or a collapsed flue liner blocking exhaust, also need immediate professional attention. Don't use the system until we've assessed it. Safety first, always.
We're open Monday through Friday 7:30 AM to 8:00 PM, Saturday 8:00 AM to 7:30 PM, and Sunday 8:00 AM to 7:30 PM. Our live coordinator answers calls during these hours and connects you with the local San Francisco team. We'll give you a firm appointment window, not a vague "sometime Tuesday" runaround.
Warranty & Guarantees FAQs
We stand behind every job with The Keystone Standard: 90 days, in writing, no arguing. If something we cleaned or repaired isn't right, we come back and make it right. No paperwork, no runaround. It's been our way since 2014, and it's why San Francisco homeowners call us back year after year.
It covers our workmanship and the materials we install. If a cap we mounted leaks, a liner we sealed fails, or creosote buildup returns abnormally fast due to our incomplete cleaning, we return and fix it at no charge. It doesn't cover new damage from chimney fires, earthquakes, or changes in how you use the system. The full terms are on our guarantee page, and we'll review them with you before any major work.
Manufacturer warranties vary by product. Gelco and Olympia Chimney caps typically carry limited lifetime warranties against defects. Famco and Copperfield components carry their own stated coverage. We pass those warranties through to you and help with any claims if issues arise. Our 90-day Keystone Standard covers the installation itself, regardless of what the manufacturer offers.
Call us. We're local, we're established, and we plan to be sweeping chimneys in San Francisco for decades to come. A company that plans to be in town in thirty years acts like it. If it's within 90 days and it's our work, we fix it. If it's outside that window, we'll still come look and give you an honest assessment. That's Standing behind it, the S in our K.E.Y.S. code.
