We’re not strangers to Somerville. Our technicians know the difference between a coal-era flue in a Highland Avenue Victorian and a converted gas-vent stack in a Pearl Street triple-decker. That local knowledge matters because Somerville’s chimneys are rarely simple. Most residential buildings here date from 1885 to 1930, and their chimneys have survived multiple fuel conversions, decades of freeze-thaw punishment, and repairs by previous owners who sometimes left problems buried behind brick. We document everything with a Level 2 camera inspection before recommending any work. Photos you can see, a plain-English verdict.

Why Hearthstone Chimney Co. Is Somerville’s Preferred Chimney Repair Company

Somerville homeowners have called us back for decades because we treat triple-decker chimneys with the care they require. Coordinating access across three separately-tenanted floors is standard practice for our team, not an inconvenience we charge extra for. We’ve repointed crowns on stacks along Broadway, rebuilt spalling brick near Union Square, and traced mysterious smoke patterns through shared flue walls in Winter Hill - always with the same method: camera first, estimate second, repair third.

Our 90-Day Done Right Promise applies to every job in Somerville. If it’s not right, we come back. In writing, no arguing. That promise has governed our work since 1984, and it’s why customers in Cambridge and Medford hear our name from their Somerville neighbors.

Calls are answered by a live person, every hour of every day. No voicemail, no callback queue. When a chimney crown is shedding mortar onto your roof or you’re smelling smoke from a neighbor’s unit, you reach someone who can dispatch a background-checked, uniformed technician - most repairs completed in a single visit with no-hassle upfront pricing.

Scheduling and dispatch are coordinated from our Boston office, but our crews serve Somerville locally. We know the parking realities near Assembly Row, the narrow access between triple-deckers in East Somerville, and the way winter wind tunnels down certain streets to accelerate mortar deterioration. That matters when we’re estimating how long a crown repair will take or whether we’ll need to stage materials on the sidewalk.

Our Chimney Repair Services in Somerville

Mortar Repointing

Somerville’s freeze-thaw cycles are brutal on mortar. Dozens of cycles each winter open joints on chimney crowns and between courses of brick, especially on the tall, tightly packed triple-decker stacks that get minimal sun exposure between buildings. By spring, what was sound pointing in October is crumbling sand. Our repointing removes deteriorated mortar to proper depth, matches the original joint profile, and uses professional-grade mixes formulated for New England’s climate - not the fast-set products some crews use that fail within two seasons. A typical mortar repointing job on a Somerville triple-decker chimney runs $650-$1,200.

Spalling Brick Repair

Spalling - brick faces popping off due to moisture freezing inside - is epidemic on Somerville’s older chimneys. The combination of oversized original flues (designed for coal draft, now venting low-temp gas) and deteriorated crowns means moisture enters the stack, freezes, and exfoliates the brick surface. In Winter Hill and near Davis Square, we’ve replaced entire courses on triple-decker stacks where spalling threatened structural integrity. We source matching brick when possible and rebuild with proper bonding patterns, not surface patches. Spalling repair in Somerville typically ranges from $800-$2,200 depending on height and access.

Chimney Waterproofing

Somerville’s long heating season, roughly October through April, keeps chimneys warm and exterior masonry cold - a temperature differential that draws moisture into the brick. Waterproofing with a breathable silane/siloxane treatment (we use professional-grade formulations from Copperfield and Gelco) stops liquid water while letting vapor escape. Critical for triple-decker stacks where a single leak affects three households. Waterproofing a typical Somerville chimney runs $450-$850 and carries our 90-Day Done Right Promise.

Flashing Repair

The intersection where chimney meets roof is a common failure point on Somerville’s older buildings, many of which have seen multiple roof layers without proper flashing updates. We remove old flashing, inspect the underlying structure for rot, and install new step and counter flashing with proper overlap and sealant. In Somerville’s dense neighborhoods, we take care to protect adjacent properties during the work. Flashing repair typically runs $550-$1,100.

Our Chimney Repair team also handles full chimney rebuilding and tuckpointing for Somerville homeowners facing more extensive deterioration. Every project starts with the same Level 2 camera inspection and photo documentation.

Trusted Brands We Service in Somerville

We stock professional-grade materials from DuraFlex, HeatShield, Gelco, and Copperfield - no builder-grade substitutes. For Somerville’s triple-decker chimneys, that means flue liners rated for multi-unit applications, crown repair mixes that flex with freeze-thaw stress, and waterproofing treatments proven in New England’s coastal climate. Because we maintain inventory for this market, most Somerville repairs don’t wait on parts. Our technicians arrive with what they need to complete the job in one visit, whether that’s repointing a Winter Hill crown or rebuilding spalled brick near Magoun Square.

Common Chimney Repair Problems We See in Somerville Homes

• Undocumented flue caps in triple-deckers. In East Somerville and Winter Hill, we regularly find middle-floor flues that a previous owner capped without recording it. A tenant upstairs lights a gas insert, and smoke traces down through a cracked common flue wall into a neighbor’s kitchen below. Our Level 2 inspection locates these before any repair begins.
• Oversized flues venting low-temperature gas appliances. Somerville’s housing stock converted from coal to oil to natural gas, leaving flues designed for high-heat coal draft now serving appliances that never warm the masonry enough. The result is chronic condensation, accelerated liner spalling, and creosote stratification on remaining surfaces.
• Freeze-thaw destruction of mortar and crown brick. Somerville sits squarely in the New England freeze-thaw belt. Dozens of cycles each winter relentlessly open mortar joints and crack brick on chimney crowns, especially on tall triple-decker stacks with minimal sun exposure between buildings.
• Cracked terra cotta liners in shared stacks. With three or four separate flues inside one brick chimney, a crack in any liner risks cross-contamination between units. Carbon monoxide backdrafting into a neighboring apartment is a real hazard we’ve documented on camera in Somerville triple-deckers.
