We’ve been working on Somerville chimneys since 1984. That means we’ve repointed mortar on triple-deckers near Union Square, rebuilt crowns in Winter Hill, and replaced flashing along Highland Avenue before the morning commute. We know the narrow lots, the shared driveways, and the parking situation around Davis Square. Our technicians carry the materials they need on the truck, so we’re not making a second trip because someone forgot the HeatShield.
Why Hearthstone Chimney Co. Is Somerville’s Preferred Chimney Repair Company
Somerville homeowners don’t have patience for contractors who treat the city like an afterthought. We’re here because we’ve earned the work, one chimney at a time.
Local reputation built over decades. We’ve served the Boston metro area for over 42 years, and Somerville has been central to that service from the start. Triple-decker landlords in 02143 call us back because we document every flue in the stack, not just the one that complained. Homeowners in 02144 recommend us because we explain what we found in plain English and leave photos they can show their insurance company.
Response time that respects your schedule. From our dispatch position, we can reach any Somerville address within 30 minutes during normal business hours. Emergency calls - a chimney leak soaking plaster, a cap torn off in a nor’easter - get same-day response. We don’t make you wait three days for water to destroy your ceiling.
We understand Somerville’s housing reality. The triple-decker on your street was built around 1905 with soft brick and lime mortar, designed for a coal furnace that’s been gone for fifty years. That history matters. We know how to work with landlords who need to coordinate access across three units, and we know the Somerville building department’s expectations for chimney work on rental properties.
Our Chimney Repair Services in Somerville
Mortar Repointing
In Somerville’s pre-1920 triple-deckers, the original lime mortar between bricks has endured a century of freeze-thaw cycles, coal soot, and now gas condensation. When we grind out the failed joints and repoint with matching mortar, we’re not just filling gaps - we’re restoring structural integrity to a chimney that three families depend on. A typical repointing job on a Somerville triple-decker chimney runs $1,800-$3,200 for the full exterior, less for partial sections.
Spalling Brick Repair
Somerville’s coastal humidity keeps moisture trapped in brick longer than in inland communities like Malden, and when January temperatures swing from 15°F to 45°F in 48 hours, that moisture expands and contracts with destructive force. Spalling - the flaking and crumbling of brick faces - is epidemic along Winter Hill and near Powder House Park. We remove damaged brick and install matching replacements, or apply specialized resurfacing compounds when wholesale replacement isn’t practical. Most spalling repairs in Somerville fall between $650 and $1,900.
Chimney Waterproofing
A porous chimney in Somerville absorbs every nor’easter and every spring downpour. Our waterproofing treatment uses professional-grade silane/siloxane sealers from Copperfield and Famco that penetrate the brick rather than forming a surface film that traps moisture. We apply it after any necessary repointing, and we guarantee it won’t alter the appearance of your historic masonry. Waterproofing a standard Somerville triple-decker chimney typically costs $450-$850.
Flashing Repair
The junction where your chimney meets the roof is the most leak-prone point on any Somerville home, and on triple-deckers with low-slope shed roofs or complex valleys, the flashing takes a beating. We fabricate and install custom step flashing and counterflashing using DuraFlex components where appropriate, sealed with high-temperature compounds that flex with thermal expansion. Flashing repair in Somerville generally runs $550-$1,400 depending on roof complexity and whether deck repair is needed underneath.
We also handle Chimney Cap & Crown in Somerville - crown reconstruction and cap installation that protects the entire flue system from water intrusion and animal entry.

Trusted Brands We Service in Somerville
We don’t substitute builder-grade materials to pad margins. Our trucks carry professional-grade inventory from DuraFlex, HeatShield, Gelco, and Famco - brands that publish test data and stand behind their products. For Somerville customers, this means we can often complete a repair without waiting for a parts order to clear traffic on I-93. When we rebuild a crown with HeatShield Cerfractory Foam or handle a Chimney Liner & Rebuild in Somerville, we’re using the same materials specified by engineers for commercial installations. The job gets done right, and it gets done in one visit.
Common Chimney Repair Problems We See in Somerville Homes
- Multi-flue chimneys with collapsed or missing liners. In Somerville’s triple-deckers, a single exterior stack often contains four or more flues serving three heating appliances and a fireplace. When one liner fails, exhaust can cross-contaminate adjacent flues. We inspect every flue in the stack with a Level-2 camera, document each with photos, and provide a plain-English verdict for the landlord and every tenant.
- Crown cracks from rapid freeze-thaw cycling. Somerville’s January weather pattern - hard freeze, rapid thaw, hard freeze again - destroys concrete crowns in three to five years if they’re not properly sealed. We rebuild crowns with proper slope and overhang, then seal them against the next cycle.
- Disputed maintenance responsibility between landlords and tenants. Because Somerville’s triple-deckers put three households under one chimney, we often arrive to find years of deferred maintenance because no single party wanted to initiate the call. We provide one written estimate addressed to the owner, with clear documentation of which flues serve which units, so responsibility is unambiguous.
- Flash rust and deteriorated flashing on low-slope roofs. Many Somerville triple-deckers have shallow-pitch shed roofs where snow sits and ice dams form. The flashing corrodes from underneath, and leaks appear in top-floor ceilings during March thaws. We remove the damaged flashing, inspect the deck, and install new custom-fabricated material with proper drainage.
