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.

AfterFast, Reliable Chimney Cleaning & Sweep Across Boston
A professional chimney sweep in Boston typically costs $180-$320 for a standard Level 1 cleaning with inspection, while a Level 2 camera inspection runs $350-$550 depending on flue count and access. Most single-family and triple-decker jobs in Boston are completed in one visit. Call (857) 597-5950 to book - a live person answers 24 hours a day, and we’ll give you an exact price before we schedule.
We’ve been dispatching crews from our Boston office to homes across the city for over 42 years. That means we know the difference between a Back Bay rowhouse chimney that burned coal for sixty years and a triple-decker stack in Dorchester serving three separate boilers. The salt air off Boston Harbor, the November-March freeze-thaw cycle, and the city’s pre-World War II housing stock create problems that don’t show up in suburban systems. Our Chimney Cleaning & Sweep team treats every flue like the safety system it is - documented with photos, explained in plain English, and backed by our 90-Day Done Right Promise in writing.
Why Hearthstone Chimney Co. Is Boston’s Preferred Chimney Cleaning & Sweep Company
Boston homeowners don’t need a sales pitch. They need a sweep who shows up when promised, explains what the camera found, and charges what was quoted. That’s been our standard since 1984.
Our technicians are background-checked, uniformed, and trained to complete most jobs in a single visit. We don’t subcontract to day laborers or send out crews who’ve never worked on a triple-decker stack. When we inspect a chimney in Jamaica Plain or South Boston, we understand that one cracked clay liner in a shared stack puts every tenant at risk - and we document it with photos you can see, not jargon you can’t.
Our 90-Day Done Right Promise means if it’s not right, we come back. No paperwork to dig up, no arguing, no runaround. In a city where contractors have come and gone for decades, we’ve answered the phone with a live person every hour of every day for over 42 years. That’s not a marketing claim. It’s how we know we’ll still be here when you need us next.
Our Chimney Cleaning & Sweep Services in Boston
Level 1 Inspection
A Level 1 inspection is the baseline for any Boston chimney that hasn’t changed appliances or suffered damage in the past year. We examine the readily accessible portions of the chimney interior and exterior, check for obstructions and combustible deposits, and verify that the flue is properly connected to your appliance. For most Beacon Hill and South End rowhouses with a single fireplace flue, this takes about 45 minutes and includes a written condition report with photos.
Level 2 Inspection
This is where our Boston expertise matters most. A Level 2 inspection includes everything in Level 1, plus a full camera scan of every flue interior - critical in triple-deckers where multiple units share one chimney stack. In Dorchester, Jamaica Plain, and East Boston, we regularly find that a tenant who called about one flue actually has cracked liners across all three stacked units. Our camera doesn’t miss it. You get photos of every flue, a plain-English verdict on each, and a priority list of what needs attention now versus what can wait. This documentation protects you, your neighbors, and your landlord if you’re renting.
Creosote Removal
Boston’s legacy of coal heating left something behind in thousands of chimneys: hardened, glazed creosote that standard brushing won’t touch. In 1880s-1920s triple-deckers and rowhouses across the city, we find flues coated with deposits from decades of coal smoke, later covered by oil or gas soot. First-degree creosote - flaky, brushable - comes out with a standard sweep. Third-degree glazed creosote, common in under-maintained Boston chimneys, requires chemical treatment and rotary removal. We assess what you’ve got before we quote, and we don’t pretend a quick brush will solve a glaze problem.
Soot Removal
Modern oil and gas appliances produce fine soot that builds up where you can’t see it, restricting draft and creating a fire hazard. In Boston’s triple-deckers, soot accumulation in the smoke chamber can migrate between flues, especially when shared masonry has deteriorated. Our soot removal includes HEPA-containment vacuuming and brushing of the entire flue length, smoke chamber, and firebox. We finish with a draft test to confirm your appliance is drawing properly - because in a shared stack, your draft depends partly on conditions two floors away.
Annual Sweep
The National Fire Protection Association recommends annual inspection and sweeping for all chimney systems. In Boston, we’d add: if you’re within a mile of salt water, inspect your cap and flashing twice yearly. The corrosion accelerates dramatically. Our $89 Seasonal Tune-Up includes a Level 1 inspection, basic sweep, and exterior cap and crown check - a smart annual habit for Boston homeowners who’d rather prevent problems than discover them in January.
Fireplace Cleaning
Even gas fireplaces in Boston condos and townhouses need annual service. Spider webs in the burner ports, deteriorating ember material, and blocked venting create real hazards. We clean and inspect gas and wood-burning fireplaces across the city, from high-efficiency inserts in South Boston lofts to original coal-converted hearths in Back Bay brownstones.

Trusted Brands We Service in Boston
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from Gelco, Olympia Chimney, and Copperfield - brands that hold up to Boston’s salt air and freeze-thaw abuse. When your cap needs replacement in Charlestown or your liner needs resurfacing in Dorchester, we’re not ordering parts from a catalog and making you wait two weeks. We stock the components that fail most often on Boston chimneys, including stainless steel caps rated for marine environments and HeatShield cerfractory resurfacing material for deteriorated clay liners. Most repairs are completed same visit.
Common Chimney Cleaning & Sweep Problems We See in Boston Homes
- Galvanised caps and flashing corroded by harbor salt. In Charlestown, East Boston, and the South Boston waterfront, we’ve replaced caps that failed in under five years because the salt-laden air ate through galvanised steel. Stainless steel caps from Olympia Chimney last dramatically longer - we measure the difference in years, not months.
- Freeze-thaw spalling on soft-brick Federal and Victorian chimneys. Boston’s genuine winter freeze-thaw cycle drives water deep into aging mortar joints. We see crown deterioration and brick spalling across Back Bay, the South End, and Beacon Hill that simply doesn’t occur at this pace in milder climates.
- Cracked, undersized clay liners in converted coal flues. The majority of Boston’s housing stock predates World War II. Clay flues designed for coal were later pressed into oil or gas service, leaving liners that are frequently cracked, too narrow for modern appliances, and coated with hardened legacy creosote. A Level 2 camera inspection reveals what a glance cannot.
- Cross-contamination between stacked flues in triple-deckers. When one unit’s boiler backdrafts into a shared smoke chamber, combustion gases can enter neighboring apartments through liner breaches. This is not theoretical - our Dorchester Avenue field call confirmed it. Whole-stack assessment is essential, not optional.

What moves you within these ranges? Flue count is the big one - a triple-decker in Dorchester with three separate liners takes longer to inspect properly than a single-family cap in West Roxbury. Access matters too: steep slate roofs in Beacon Hill require different setup than flat-roofed triple-deckers. The condition of your creosote - brushable versus glazed - determines whether standard sweeping suffices or chemical treatment is needed. We assess this during our initial camera look and give you a fixed price before any work begins. No surprises on the bill. Seniors and veterans receive a permanent 5% discount.

FAQs - Chimney Cleaning & Sweep in Boston
All three flues should be inspected, not just yours. In Boston’s triple-decker belt, a single masonry chimney stack contains multiple stacked flues serving separate units, and shared deterioration or liner breaches in one flue create hazards for every tenant in the building. Our Level 2 inspection includes camera documentation of all flues in the stack, with photos and a plain-English verdict for each. Call (857) 597-5950 to schedule - we’ll confirm the flue count when you book so there are no surprises.
Galvanised steel caps and flashing in waterfront Boston neighborhoods typically show significant corrosion in 3-5 years, versus 8-12 years in inland climates. The salt-laden air off Boston Harbor accelerates rust dramatically in Charlestown, East Boston, and the South Boston waterfront. We recommend stainless steel caps for any chimney within a mile of the harbor, and we include cap and flashing condition in every inspection. Call (857) 597-5950 for a free cap assessment.
Yes, it matters significantly. Coal-era clay flue liners in Boston’s 1880s-1920s housing stock were designed for different combustion temperatures and draft patterns than modern oil, gas, or wood appliances. They’re frequently cracked, undersized for current use, and coated with hardened legacy creosote that standard brushing won’t remove. Our Level 2 camera inspection identifies these conditions precisely, and we’ve resurfaced dozens of deteriorated coal-era liners with HeatShield cerfractory material. Call (857) 597-5950 to assess your specific flue condition.
Yes - annual inspection is recommended regardless of use frequency, and in Boston’s climate it’s particularly important. Even minimal burning produces creosote, and our freeze-thaw cycle damages masonry whether the fireplace is active or not. Birds, squirrels, and moisture intrusion create blockages and deterioration independent of how often you light a fire. The $89 Seasonal Tune-Up is designed for exactly this situation: a low-cost annual check that catches problems before they become expensive. Call (857) 597-5950 to book.
First-degree creosote is flaky, dusty, and brushes off easily - what you’d find in a well-maintained, annually swept flue. Third-degree glazed creosote is hard, shiny, and bonded to the flue liner like enamel; it requires chemical treatment to soften before rotary removal, and it’s common in Boston chimneys with decades of deferred maintenance, especially converted coal flues. We diagnose which type you have during our initial camera inspection and quote accordingly - no guesswork, no pretending a standard sweep will fix a glaze problem. Call (857) 597-5950 for an exact assessment.
