Mortar Repointing

Repointing in Collinsville is rarely a simple grind-and-fill job. The historic soft brick in these 130-170-year-old chimneys was originally set with lime mortar, which breathes and flexes with temperature swings. Too often, a previous owner or contractor used hard Portland cement instead. That cement cracks first under freeze-thaw cycling, then the surrounding brick spalls in sheets. We remove the incompatible mortar and restore joints with period-appropriate lime mortar - the only way to stop the cycle without destroying more brick. On a two-story frame cottage off River Street near the old Collins Company complex, we opened a soft-brick stack that had been repointed years earlier with hard Portland cement; the surrounding brick was spalling in sheets and the crown had cracked, pulling the flashing loose. Because the flue was shared with the adjoining unit, a neighbor’s appliance was venting partly into this address’s smoke chamber, so we rebuilt the crown, restored the joints with lime mortar, installed a correctly sized HeatShield flue liner, and sealed the shared-stack breach. We finished with a Level 2 inspection, a new chimney cap, and a waterproofing coat to break the freeze-thaw cycle that started the damage.

Spalling Brick Repair

Spalling - the flaking and crumbling of brick faces - is widespread in Collinsville’s valley housing. The Farmington River valley pools cold air in winter, extending the freeze-thaw season beyond what hilltop chimneys in Canton or Simsbury experience. Water penetrates compromised mortar joints, freezes, expands, and pops off brick faces. We replace spalled brick with matching units where possible, seal the crown, and apply breathable waterproofing to keep moisture out without trapping vapor inside. The goal is stopping the damage at its source rather than chasing symptoms year after year.

Chimney Waterproofing

Water is the enemy of every chimney, but Collinsville’s conditions make waterproofing especially critical. The channeled wind patterns along the river corridor drive rain into masonry with unusual persistence, and the extended cold season means more freeze-thaw cycles. We apply professional-grade breathable sealers that repel liquid water while letting water vapor escape - essential for historic soft brick that needs to breathe. This isn’t a DIY spray-job. We prep the surface, repair open joints first, and use products formulated for severe exposure, not the hardware-store versions that trap moisture and accelerate damage.

Flashing Repair

Flashing failure is common in Collinsville’s older housing stock because original installations were often rudimentary, and decades of thermal movement have opened gaps. We see lifted counter-flashing, rusted step flashing, and sealant that’s hardened and cracked. Our crews fabricate custom flashing details where needed and integrate them with the roofing system properly. On the River Street job, the cracked crown had actually pulled the flashing loose, creating a direct water path into the attic. We repaired both elements together - the only way to solve it permanently.

Chimney Rebuilding

When spalling, joint failure, and structural cracking have compromised too much of the stack, partial or full rebuilding becomes necessary. In Collinsville, we rebuild with matching brick and proper lime-mortar bedding, restoring structural integrity while preserving the historic character that makes these mill-village homes distinctive. We also take the opportunity to correct flue sizing and isolate shared stacks, so the rebuilt chimney functions correctly for modern appliances and protects against cross-contamination.

Tuckpointing

Tuckpointing in Collinsville follows the same principles as our repointing work - lime mortar for historic soft brick, careful color matching, and full joint preparation rather than surface smearing. The difference is largely cosmetic precision: tuckpointing restores the fine, narrow joint lines that give these old chimneys their crisp appearance. We match the original joint profile and aggregate exposure so the repair disappears into the facade.

Trusted Brands We Service in Collinsville

We work exclusively with professional-grade materials from industry-trusted manufacturers - no builder-grade substitutes that fail early. For flue liners and restoration systems, we specify HeatShield for ceramic resurfacing and Olympia Chimney for stainless steel relining.

We stock common sizes and configurations locally, so most Collinsville repairs don’t wait on special orders. When your chimney needs a part, we install the one that was made for the job.

Common Chimney Repair Problems We See in Collinsville Homes

• Portland-cement repointing destroying soft brick. A previous repair used hard mortar on historic brick. The cement cracks, water enters, freezes, and spalls the surrounding brick worse than before. The fix is removal and lime-mortar restoration - not another layer of cement.
• Oversized flues mismatched to converted appliances. Wood- and coal-era chimneys vent modern oil or gas equipment poorly. Weak draft lets exhaust linger, and the valley’s downdraft conditions accelerate third-degree creosote glazing. A correctly sized liner solves both problems.
• Shared-flue cross-contamination in row houses. Failed mortar joints between attached units let one neighbor’s appliance exhaust migrate into the next flue. Our repairs isolate and seal these shared stacks, protecting both households.
• Crown cracks pulling flashing and opening water paths. The concrete crown takes the worst weather exposure. When it cracks, water runs behind the flashing, into the attic, and down the interior of the stack. Crown rebuild plus flashing repair stops it.
