At Gavin Chimney Co, we cut through the smoke and mirrors of the chimney industry with no-nonsense, checklist-driven service you can trust. Boston’s historic homes and modern condos both demand precision, and we deliver it—no upsells, no delays, just a clean flue and a safer hearth. Our crew arrives on time, works efficiently, and leaves your chimney in code-compliant condition, period. We’re the only sweep in Boston who treats every appointment like a fire-prevention audit, not a sales pitch.
Other sweeps treat your chimney like a mystery box. We treat it like a system that needs clear answers. No vague estimates. No pressure to buy add-ons you don’t need. Just honest work, fair pricing, and a team that shows up prepared. We’re licensed, insured, and backed by a 10-year warranty because we stand behind what we do.
A blocked flue or a cracked liner won’t wait for a convenient appointment. We reserve same-day slots for urgent jobs, especially after storms or sudden draft failures. Call by noon, and we’ll be at your Boston home by evening. No waiting weeks for a ‘next available’ slot. Just fast, reliable service when you need it most.
Boston’s older homes have chimneys built for a different era. We know the local building codes, historic masonry techniques, and the unique challenges of coastal humidity. Whether your chimney’s in Back Bay, the North End, or along the Charles, we’ve seen it before—and we know how to fix it right.
A chimney sweep’s job isn’t done when the soot’s cleared. We guarantee our work with a 10-year warranty on labor and materials. If something goes wrong, we fix it—no questions asked. Other sweeps? They’ll point to a fine print clause. We’ll point to our warranty and get to work.
Skip the phone tag. Use our online scheduler to pick a time that works for you. We’ll confirm your appointment within the hour and send a reminder the day before. No high-pressure sales. No vague ‘estimates’—just a firm price upfront so you know exactly what to expect.
Our techs show up with the right tools, the right permits, and a checklist for your specific chimney. We’ll inspect the system before we start, explain what we’re doing, and get to work. No surprises. No delays. Just a smooth, efficient service that respects your time.
We don’t just sweep—we verify. After clearing creosote and debris, we inspect for damage, test draft performance, and ensure your chimney meets Boston’s safety standards. When we’re done, your home is cleaner, safer, and ready for the next fire.
You’ll get a detailed report with before-and-after photos, a summary of our findings, and clear next steps—whether it’s a repair, a waterproofing job, or a simple maintenance tip. No vague advice. Just actionable insights so you can make the best decision for your home.
"Gavin Chimney Co. swept my 1890s brick chimney last week. They found a hairline crack in the flue that I’d missed for years. Fixed it on the spot for a fair price. No upsells, no nonsense—just good work. Highly recommend."
"Called for a routine sweep. They spotted a nest of squirrels in the flue and removed it safely. Explained why a cap was essential for Boston’s weather. Worked clean, arrived on time, and charged exactly what they quoted. Trustworthy."
"After a chimney fire scare, I needed a full inspection. They did Level 2 with cameras and found a blockage I didn’t know about. Fixed it before winter hit. Their warranty gave me peace of mind. Wouldn’t trust anyone else."
"Used them for waterproofing last spring. My chimney was crumbling from salt air. They sealed it properly, and now it looks brand new. No more white stains or moisture damage. Worth every penny."
"Same-day service when my damper failed before Thanksgiving. They had me up and running in under 4 hours. Fair price, no hidden fees. Boston winters are brutal—glad I called them."
"They serviced my gas fireplace and found a cracked heat exchanger. Fixed it before it became a carbon monoxide risk. Their report was clear, with photos and pricing. No other company gave me that level of detail."

A Level 2 inspection in Back Bay runs $175–$225, while a routine sweep is $125–$175. The extra $50–$100 covers video scanning, a detailed report, and photos—required if you’re selling your home or have had a chimney fire. We’ll email you the footage same-day, so you see what we see. No upsells, just the inspection you need.
Yes, but only if we catch it early. Cracked tiles let heat escape and water in, risking a chimney fire or collapse. We carry OEM replacements and can reline your flue in under a day. In the North End’s tight row houses, access is tricky—we bring the right tools to get the job done without tearing apart your walls.
Check your firebox. If you see more than 1/8 inch of creosote buildup or your logs won’t catch easily, it’s time. Also, if you smell a campfire scent indoors or notice smoke spilling into the room, don’t wait—call us. Boston’s damp air accelerates creosote formation, so even gas fireplaces can trap moisture.
We do, but only for true emergencies—like a bird’s nest blocking your flue or a sudden downdraft filling your home with smoke. Same-day service in Boston costs $200–$300 on top of the standard fee. We prioritize safety over convenience, so if it’s not an immediate hazard, we’ll schedule you within 48 hours.
We’re 10–15% higher than the cheapest sweeps in the South End, but we include a Level 2 inspection and a written report—most competitors charge extra for both. Our crew is licensed, insured, and background-checked, so you’re not paying for cut-rate labor. In a city where shortcuts cost lives, we don’t cut corners.
Boston’s older buildings mean more masonry chimneys, tighter spaces, and stricter code enforcement. Cambridge has more modern construction, so sweeps there deal with gas lines and stainless steel liners more often. We adapt our process to your home’s era—whether it’s a 19th-century Beacon Hill townhouse or a Kendall Square high-rise.
DIY sweeping risks missing creosote glaze, damaging your flue, or leaving debris in your chimney. Boston’s building codes require a licensed sweep for inspections, and insurance companies deny claims if a fire is traced to improper maintenance. We’ve seen ‘DIY’ jobs that cost homeowners $5,000 in repairs. Hire a pro—it’s cheaper in the long run.
Hourly pricing is a red flag—it incentivizes dragging out the job. We quote flat rates because we know Boston homeowners value transparency. Our fee covers labor, equipment, disposal, and a Level 1 inspection. If we find extra work, we’ll give you a separate quote upfront. No surprises, no nickel-and-diming.
