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.

Why Hearthstone Chimney Co. Is Boston’s Preferred Chimney Liner & Rebuild Company
Boston’s chimney problems aren’t generic. A triple-decker in Dorchester with three oil boilers sharing one stack needs a different eye than a single-family in the suburbs. Our technicians have worked the narrow streets of Jamaica Plain, the hill climbs of Charlestown, and the tight alleys behind Beacon Hill rowhouses. We know what salt air off the harbor does to galvanized caps. We know why a 1920s clay liner converted from coal to gas is probably cracked. And we know that in Boston, a “simple” liner call often turns into a whole-stack assessment because three families share one chimney.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon. No scare tactics. If your liner has five years left, we’ll say so. If it’s breached and sending carbon monoxide into the upstairs unit, we’ll show you the crack on screen and explain exactly what it costs to fix.
Every job is backed by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back. That’s the Keystone Standard: Krafted right, Every time, Your home first, Standing behind it.
Our Boston-area customers call because they want the job done once, done correctly, and never thought about again. That’s who we are.
Our Chimney Liner & Rebuild Services in Boston
Stainless Steel Liner Installation
Boston’s salt-laden harbor air corrodes galvanized chimney components in half the time you’d see inland. That’s why we install stainless steel liners from DuraFlex and Olympia Chimney as our standard - not an upsell, just the right material for this climate. A stainless liner resists the chlorides in coastal air, handles the acidic condensation from modern high-efficiency boilers, and carries a lifetime warranty in most applications. In waterfront neighborhoods like Charlestown, East Boston, and South Boston, we won’t install anything less. A typical stainless steel liner installation in Boston runs $2,800-$4,500 depending on flue height and diameter.
Flexible Liner Systems
Some of Boston’s oldest chimneys - especially the offset flues in Federal-era Beacon Hill rowhouses or the angled stacks in Back Bay Victorians - won’t accept a rigid liner without major demolition. Flexible liners from DuraFlex navigate these offsets without tearing down walls. Our techs measure with a camera first, then pull the liner through from the top. Most flexible liner jobs in Boston are done in one day, with the boiler back online by evening. Typical cost: $2,400-$3,800.
Liner Replacement
Clay tile liners in Boston’s pre-WWII housing stock were designed for coal fires, not modern oil or gas appliances. They’re often undersized, cracked from decades of thermal cycling, or coated with hardened creosote that can’t be swept clean. We remove the failed liner - sometimes in pieces, sometimes as a collapsed shell - and install a new system sized correctly for your appliance. In triple-deckers across Dorchester and Jamaica Plain, we frequently find that one unit’s liner failure has already begun compromising the adjacent flues. We inspect every flue in the stack. Replacement jobs in Boston typically range $2,200-$4,800.
Partial Chimney Rebuild
When the top courses of brick are spalling, the crown is cracked through, or the flue opening has deteriorated beyond liner repair, a partial rebuild is the square deal. We rebuild from the roofline up, replacing damaged brick with matching units, pouring a new concrete crown with proper overhang and drip edge, and installing a stainless steel cap. In Boston’s freeze-thaw climate, the crown is everything - water sits in a crack, expands overnight at 20°F, and by March your chimney top looks like it was shelled. A partial rebuild in Boston runs $1,800-$4,200 depending on height and brick matching.

Trusted Brands We Service in Boston
We work exclusively with professional-grade materials - no builder-grade substitutes that fail in Boston’s climate. Our trucks carry DuraFlex stainless liners and flexible systems, HeatShield cerfractory flue resurfacing products, and Gelco stainless caps and flashing kits. For crown repairs and rebuilds, we specify Olympia Chimney materials and Famco components where appropriate. These are the brands that other chimney companies sell; we install them every day and stock common sizes so Boston customers aren’t waiting two weeks for parts. When your boiler is down in January, that matters.
Common Chimney Liner & Rebuild Problems We See in Boston Homes
- Galvanized cap and flashing corrosion from harbor salt air. In waterfront neighborhoods, we’ve pulled caps that looked like lace after seven years. Water gets in, freezes, and spalls the brick beneath. Stainless steel caps and proper counter-flashing are the fix - not optional here.
- Freeze-thaw cycle damage to clay tile liners. Boston’s real winter - November through March, with temperatures swinging from 40°F to single digits weekly - cracks clay liners that were already marginal. The crack opens, acidic condensate reaches the brick, and the liner collapses into the flue.
- Cross-contamination between triple-decker flues. When one unit’s liner is breached, exhaust can enter another unit’s flue through shared masonry joints. We’ve documented carbon monoxide readings in second-floor units caused by a first-floor liner failure. Whole-stack assessment is standard on every triple-decker call.
- Third-degree creosote in coal-converted flues. The hard, glazed creosote from decades of coal and later oil burning can’t be removed by sweeping. It reduces flue diameter, traps acidic moisture against the liner, and is the fuel source for chimney fires. We remove it with mechanical tools or specify liner replacement when the flue is too far gone.

FAQs - Chimney Liner & Rebuild in Boston
Annual Level-2 inspections are the standard for Boston triple-deckers, not every-two-years. The shared stack means one unit’s problem becomes everyone’s emergency, and the salt air plus freeze-thaw cycle accelerates deterioration beyond what NFPA 211’s minimum guidelines anticipate for inland climates. Call (857) 597-5950 to schedule - estimates are free.
Salt-laden air off Boston Harbor corrodes galvanized steel in 5-7 years versus 15+ inland. Once the cap rusts through, water enters the flue, freezes, and spalls the brick from the inside out. Stainless steel resists this corrosion and costs less over time than replacing galvanized caps twice and rebuilding the damaged brick beneath. We install Gelco and Famco stainless components as standard in waterfront neighborhoods.
Yes - exhaust gases and carbon monoxide can migrate through shared masonry joints into adjacent flues. In a triple-decker on East Cottage Street in Dorchester, our tech found a 1910s clay flue liner cracked and spalling from decades of salt air and freeze-thaw cycles. We installed a stainless steel DuraFlex liner with a new stainless cap, restoring safe draft for the oil boiler and preventing cross-contamination between the three units’ flues. That’s why we camera every flue in the stack, not just the one that called.
Third-degree creosote is a hard, glazed, tar-like deposit that forms when wood or coal burns at low temperatures with restricted airflow - exactly how Boston’s 1880s-1920s chimneys were typically operated. It cannot be removed by standard sweeping and acts as both a flue obstruction and a chimney fire fuel. We find it routinely in Dorchester and Jamaica Plain triple-deckers where coal burning left legacy deposits, later covered by oil soot. Mechanical removal or liner replacement is required.
Water enters hairline cracks in the crown or mortar joints during a January thaw, then expands by about 9% when temperatures drop below freezing overnight. Repeat this 50-100 times per winter, and the brick face pops off - spalling - or the crown cracks completely through. Boston’s soft Federal-era brick is especially vulnerable. A proper crown with drip edge and expansion joints, plus timely mortar repointing, prevents the damage that leads to rebuilds. Call (857) 597-5950 for an inspection - we’ll show you exactly what your chimney faces this winter.
