Our Chimney Repair Services in Blackstone
Mortar Repointing
The lime mortar in Blackstone’s 1885-to-1930 brick chimneys was never meant to survive 140 years of valley moisture and freeze-thaw cycling. We grind out failed joints to proper depth and repoint with color-matched, professional-grade mortar formulated for New England’s climate. A typical repointing job on a Blackstone two-family chimney runs $1,200-$2,400. We also handle Fireplace Services in Blackstone when the firebox needs attention alongside the exterior.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is epidemic on Blackstone’s north-facing chimney exposures where snow sits against the stack and moisture penetrates freeze-weakened faces. We remove damaged brick, source matching replacements when possible, and rebuild with proper bonding patterns that respect the original construction. Spalling repair on a Blackstone cottage chimney typically runs $800-$1,800. Left alone, spalling becomes a rebuild; caught early, it’s a repair.
Chimney Waterproofing
Blackstone’s valley location traps moisture, and its chimneys absorb it like wicks. We apply vapor-permeable waterproofing agents that let the brick breathe while shedding rain - critical on chimneys that were never designed for the condensation loads of modern appliances. Waterproofing a standard Blackstone chimney runs $450-$850 and includes a full inspection. We also install Chimney Cap & Crown in Blackstone when the crown itself has failed and is letting water straight into the structure.
Flashing Repair
The junction where chimney meets roof is the leak point we see most often in Blackstone’s older homes, many with multiple roof layers and irregular step flashing installed by roofers who didn’t understand masonry. We fabricate and install custom flashing using professional-grade materials, sealed with proper counter-flashing reglets cut into the brick. Flashing repair in Blackstone typically runs $350-$750. Done right, it outlasts the next roof.

Trusted Brands We Service in Blackstone
We stock Blackstone’s most commonly needed repair materials on our trucks: DuraFlex stainless liner systems for the oversized flues that dominate this market, HeatShield cerfractory resurfacing compound for restoring cracked clay liners without a full reline, and Famco chimney caps and accessories in standard sizes. When a job calls for Olympia Chimney components or Copperfield specialty flashing, we source direct and turn it around fast. No builder-grade substitutes, no waiting two weeks for parts. The brands matter because the job only holds if every component does.
Common Chimney Repair Problems We See in Blackstone Homes
- Failed clay tile liners in coal-era flues. Nearly every original Blackstone chimney was built for coal combustion with an oversized, uninsulated flue. Venting a modern 80,000 BTU oil burner through that passage produces acidic condensation that cracks clay tiles within seasons, not decades. We document the damage with camera inspection and recommend stainless liner inserts sized to the appliance.
- Deteriorated mortar from valley moisture and freeze-thaw. Blackstone’s location in the Blackstone River valley means higher ambient moisture than surrounding hill towns, and winter temperatures that swing above and below freezing for weeks. The lime mortar in pre-1930 chimneys turns to sand, joints go hollow, and water finds its way to the interior framing.
- Improper cross-border work failing MA inspection. Because Woonsocket is essentially the next town, many Blackstone properties were serviced by Rhode Island contractors working to RI codes. When those homes sell and a Massachusetts inspector examines the chimney, liner sizing and clearance violations surface routinely. We remediate to MA standards with documentation that satisfies the transaction.
- Multiple appliances sharing a single flue. The two-family housing stock in Blackstone often has one chimney serving two furnaces, or a furnace and a water heater, through a common flue - a configuration that fails modern venting codes and creates dangerous draft interference. We separate the venting or install dedicated liner systems.

We offset this with our $50-off repair offer and transparent upfront pricing that prevents sticker shock.
