Thompson Chimney Inc. doesn’t just clear out soot, we stop carbon monoxide leaks, chimney fires, and repairs that drain your wallet. We use brushless cleaning, video scans, and deep creosote removal to follow NFPA 211 rules, while some crews take shortcuts. If you smell smoke or a strange odor in your McNair neighborhood home, call before it turns into an emergency.
A chimney inspection is a visual and instrumental check of your flue, liner, and masonry to spot hidden dangers like cracks, corrosion, or creosote buildup, before they cause a fire or carbon monoxide spill.
Salem’s historic homes and modern gas fireplaces hide risks most homeowners miss. A Level I inspection (the minimum for resale or annual checks) costs $120–$180 and takes 45 minutes. We use a chimney camera to spot: - Creosote stage 3 buildup (glassy, flammable tar that ignites at 1,100°F, common in wood-burning stoves after 30 fires). - Cracked flue tiles (from freeze-thaw cycles in Salem’s coastal winters). - Obstructed dampers (often missed by DIY sweeps, leading to smoke backing into homes on Derby Street).
The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends inspections before every heating season, but Salem’s high humidity accelerates creosote buildup. If your inspection reveals stage 2 or 3 creosote, we’ll sweep immediately, no upsell. Schedule your Salem inspection today to avoid a chimney fire like the one that destroyed a Lafayette Street home last winter.
5 red flags your Salem chimney needs a sweep right now, don’t wait for the next cold snap
Salem’s old brick chimneys and modern gas inserts create unique hazards. Watch for: 1. Smoke or fumes in your living space (not just the fireplace room). This means blocked flues or a failing damper, common in pre-1980 homes where masonry wasn’t sealed properly. 2. A strong, acrid smell when lighting the fire. Stage 2 creosote (like tar) burns with a chemical odor. If you smell it, extinguish the fire and call us, this is a fire waiting to happen. 3. Soot stains on your fireplace mantel or walls. Black powder on white paint isn’t just messy; it’s a sign of incomplete combustion, which can produce carbon monoxide. 4. Animals nesting in your chimney. Birds, squirrels, or raccoons (common in Salem’s backyards) leave nests that block airflow. We’ve removed 12 nests this year alone, some with live critters inside. 5. Your gas fireplace pilot light won’t stay lit. A clogged flue starves the flame of oxygen, causing yellow tips (a CO risk). This is a code violation in Salem’s rental properties.
Pro tip: If your chimney was last swept after 2020, it’s due. The EPA’s Burn Wise program the EPA's Burn Wise program warns that unswept chimneys release 30% more harmful pollutants, bad for your health and Salem’s air quality. See our creosote removal process to understand why brushless tools are safer for your home.
Why Salem homeowners avoid DIY chimney sweeps, and the hidden costs of cutting corners
DIY chimney sweeps using cheap brushes or shop vacuums leave: - Creosote smeared on flue walls (brushes push it deeper, increasing fire risk). - Damaged liners (metal liners bent by stiff brushes cost $800–$2,500 to replace). - Missed blockages (bird nests, mortar debris, or collapsed tiles, we found a collapsed flue in a Danvers home last month that would’ve caused a chimney fire).
Local example: A homeowner in North Salem spent $50 on a DIY kit, then called us after their gas fireplace backdrafted soot into the kitchen. The cleanup cost $420, plus a new damper ($180). Total: $650, more than a pro sweep and inspection combined.
Thompson Chimney Inc. uses rotating brushless systems and video inspections to remove 100% of creosote without damaging your chimney. Our crews are licensed in Salem and surrounding towns like Marblehead Chimney Sweep in Marblehead, MA and Beverly Chimney Sweep in Beverly, MA, so we know the quirks of North Shore masonry. Ask about our creosote removal warranty, we stand by our work.
Should I schedule a chimney sweep in Salem before winter? The answer depends on your fuel type, and Salem’s weather
Salem’s coastal climate means humidity accelerates creosote buildup. Here’s your schedule: - Wood-burning fireplaces: Sweep twice a year (once in fall, once in spring). The NFPA the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) reports 25,000 chimney fires yearly, most from unswept wood-burning units. - Gas fireplaces: Inspect annually (creosote forms slower, but gas soot is corrosive). If your chimney is over 20 years old, we recommend a Level II inspection ($250–$400) to check for rust or cracks. - Pellet stoves: Sweep once a year (pellet ash is abrasive and wears down liners faster).
Salem-specific tip: If you’ve had more than 30 fires since your last sweep, book now. Last November, a home on Summer Street had a chimney fire because the homeowner skipped their sweep after 35 fires, damage cost $12,000. See our seasonal chimney care guide for month-by-month prep.
Is it worth paying more for a licensed chimney sweep in Salem? Yes, here’s why insurance and certifications matter
Unlicensed sweeps in Salem often: - Lack liability insurance (if they damage your chimney, you’re on the hook). - Use outdated tools (rigid brushes can crack flue tiles, costing you $1,500+ to repair). - Don’t follow NFPA 211 (the fire code standard). We’ve seen sweeps leave soot in the smoke chamber, illegal and dangerous.

Questions to ask a Salem chimney pro before hiring, and warning signs to avoid
Not all chimney sweeps are equal. Ask these questions to avoid scams or unsafe work: 1. ‘Are you CSIA-certified?’ (Certification means they follow national safety standards.) 2. ‘Do you carry liability insurance?’ (If they say ‘no,’ walk away.) 3. ‘Will you use brushless tools?’ (Brushes damage flues; we use rotating systems.) 4. ‘Do you offer a warranty?’ (We do, most competitors don’t.) 5. ‘Can I see a video inspection report?’ (If they refuse, they’re hiding something.)
Salem-specific warning: Some sweeps advertise ‘cheap’ services but skip inspections. Last year, a crew in South Salem charged $80 for a sweep, then the homeowner’s chimney collapsed during a nor’easter, costing $8,000 to rebuild. Pro tip: If a sweep won’t answer these questions, they’re not the best chimney sweep in Salem. See our crew certifications to verify ours.

Frequently Asked Questions
Should I call a chimney sweep in Salem if my gas fireplace smells like sulfur?
Yes, immediately. Sulfur smells mean burning gas isn’t venting properly, often due to a clogged flue or cracked liner. This can produce carbon monoxide. Thompson Chimney Inc. offers emergency inspections for gas fireplace issues. Schedule yours today, don’t wait for symptoms to worsen.
Is it worth the cost to sweep a chimney I haven’t used in years?
Absolutely. Old chimneys hide decades of creosote and debris. Even unused chimneys need inspections, animals nest in them, and mortar deteriorates. A Level I inspection ($120–$180) catches hidden risks before you light a fire. See our unused chimney prep guide for safety steps.
What happens when you skip sweeps in a McKinley Park home with a seasonal fireplace?
Yes, creosote builds up even with light use. The NFPA the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) reports most chimney fires start from neglected, low-use fireplaces. If you’ve burned more than 10 fires since your last sweep, schedule one. Ask about our seasonal discounts for off-peak bookings.
What’s the difference between a chimney sweep and a video inspection in Salem?
A sweep removes soot/creosote; an inspection checks for structural damage. We recommend both, a sweep cleans, but an inspection finds hidden cracks or corrosion. A Level I inspection costs $120–$180 and takes 45 minutes. Learn about inspection levels to choose the right one for your home.
