Call (844) 803-1545

We’ve been working on Boston chimneys since 1984. Russell Haines started this company with the understanding that an old port city with 200-year-old brick stacks requires a different approach than suburban new construction. When we get a call from a Beacon Hill condo association about a shared flue showing moisture damage, or a Back Bay homeowner whose crown has cracked after another hard winter, we know the building before we arrive. The freeze-thaw cycling here, compounded by salt air off the harbor in the North End and Waterfront, chews through mortar joints that would last decades elsewhere. We’ve repointed chimneys on Louisburg Square, rebuilt crowns overlooking the Common, and diagnosed Chimney Liner & Rebuild - Boston issues in South End brownstones where four units share one flue. If your chimney needs attention, call us at (844) 803-1545. A live person answers, 24 hours a day.

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

Boston homeowners don’t have patience for contractors who vanish. We’ve been serving this market for over 42 years, and our Chimney Repair in Boston crew knows the difference between a Federal-era flue in 02113 and an 1880s brownstone stack in 02116. Russell Haines has walked job sites on Beacon Hill since the Reagan administration.

Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If the flue is cracked, we show you the crack. If it’s sound, we say so.

Calls reach a live person every hour of every day. Our technicians are background-checked and uniformed, and most repairs finish in one visit because we stock professional-grade materials from Gelco and Famco rather than ordering after we see the job.

Every repair carries our 90-Day Done Right Promise in writing. If it’s not right, we come back. No paperwork, no arguing. That’s the Keystone Standard.

Our Chimney Repair Services in Boston

Mortar Repointing

Boston’s 43-plus inches of annual snow and relentless freeze-thaw cycles grind away mortar joints on exposed chimney stacks. In Back Bay, where many brownstones sit on filled tidal land, we’ve documented foundation settlement that opens new gaps season after season. Our repointing matches existing mortar composition and profile, using HeatShield-compatible materials where heat exposure demands it. We grind out failed joints to proper depth, never skimming over the top. Done right, repointing on a Boston row house should last 25-30 years, though harbor-facing properties in the North End often need earlier touch-ups due to salt-air corrosion.

Spalling Brick Repair

Spalling, the flaking and crumbling of brick faces, is epidemic in Boston’s older housing stock. The soft, porous bricks used in Federal and Victorian construction absorb moisture through failed crowns or open joints, then shed their faces during freeze-thaw. We’ve replaced spalled courses on chimneys overlooking the Charles and rebuilt parapet walls in the South End where decades of neglect left brick dust on the roof. Our Chimney Repair team sources matching brick when possible, or recommends appropriate substitutes that honor the building’s character while performing better in Boston’s climate.

Chimney Waterproofing

Waterproofing a Boston chimney requires breathable, vapor-permeable sealants that won’t trap moisture inside already-saturated masonry. We apply professional-grade treatments from Olympia Chimney that allow the brick to exhale while repelling liquid water. This matters enormously in Boston’s shoulder seasons, when weeks of damp cold precede hard freezes. We’ve waterproofed chimneys on Marlborough Street and Commonwealth Avenue where previous, non-breathable coatings had accelerated the very damage they were meant to prevent. The correct application, following proper drying conditions, adds 10-15 years of protection to sound masonry.

Flashing Repair

Step flashing and counterflashing around chimney penetrations are the most common leak sources we find in Boston’s multi-unit row houses. Where a chimney passes through a flat or low-slope roof shared by multiple owners, deteriorated flashing often goes unreported until water stains appear in two units simultaneously. Our technicians document flashing condition during every inspection, and we repair or replace using copper or coated steel appropriate to the roof assembly. We also handle Chimney Cap & Crown in Boston work, since crowns and flashing fail together more often than not.

Trusted Brands We Service in Boston

We stock professional-grade materials from Gelco, Famco, and Olympia Chimney on every Boston-area truck. These aren’t builder-grade substitutes ordered from a catalog after we diagnose the problem. When we arrive at a job in 02115 or 02114, we typically have what we need to complete the repair that day. For specialized applications, Russell Haines maintains direct supplier relationships that get us HeatShield refractory materials within 24 hours. We’ve learned over four decades that keeping the right inventory matters more in a city with Boston’s parking constraints and narrow streets than in any suburban market. You don’t want us making two trips down Storrow Drive because we guessed wrong on a part.

Common Chimney Repair Problems We See in Boston Homes

• Shared flue deterioration in converted row houses. On Beacon Hill and in the South End, a single chimney stack often serves three or four separately-owned condos. A cracked liner or missing mortar joint isn’t one homeowner’s problem; it’s a multi-tenant liability that requires coordinated repair and sometimes condo board notification before work proceeds.
• Crown cracks from freeze-thaw cycling. Boston’s long, damp winters and sudden spring thaws destroy concrete crowns that lack proper overhang or expansion joints. We replace with poured concrete or pre-formed caps sized to shed water away from the brick below.
• Abandoned flues serving converted coal fireplaces. Many 19th-century Boston homes have flues that were never properly lined when coal gave way to gas inserts. These unlined masonry channels accumulate moisture and combustion byproducts, accelerating decay in the shared wall between neighboring units.
• Salt-air mortar corrosion in harbor-facing neighborhoods. The North End and Waterfront experience accelerated mortar degradation from airborne salt, cutting repointing intervals by roughly 30% compared to inland Boston neighborhoods. We specify appropriate mortar mixes for these exposures.
