Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Liner & Rebuild Across Collinsville
Chimney liner and rebuild work in Collinsville typically runs $1,800-$4,500 for most jobs, with shared-stack relines in the historic mill cottages often falling in the middle of that range. Our crews are dispatched from our Hartford office and carry DuraFlex stainless liners, lime mortar, and camera equipment sized for the narrow rooflines and attached-row access you’ll find along River Street and the old Collins Company blocks. If your chimney is original to a worker cottage built between the 1840s and 1890s, the flue was almost certainly sized for coal or wood and may now be venting a gas or oil appliance it was never designed for.

Why Hearthstone Chimney Co. Is Collinsville’s Preferred Chimney Liner & Rebuild Company
We’ve been answering calls with a live person for over 42 years, and we’ve learned that Collinsville homeowners don’t want a sales pitch - they want someone who understands what a 130-year-old soft-brick stack in a row cottage actually needs. Our Chimney Liner & Rebuild in Collinsville work is backed by the 90-Day Done Right Promise in writing, no arguing. If it’s not right, we come back.
Our technicians are background-checked and uniformed, and most liner replacements and partial rebuilds are completed in a single visit with no-hassle upfront pricing - the number on the estimate is the number on the invoice. We’ve worked on chimneys within sight of the Farmington River and along the tight streets where the Collins Company housed its workers. We know the parking is tight, the roofs are steep, and the chimneys are older than most in Hartford County. That local knowledge means we show up with the right materials and the right plan, not a guess.
Our Chimney Liner & Rebuild Services in Collinsville
Stainless Steel Liner Installation
A stainless steel liner is the right fix for most Collinsville chimneys that are still structurally sound but have a flue that no longer matches the appliance. We install DuraFlex stainless liners with sealed top plates and proper connectors, sized exactly to your boiler, furnace, or stove. In the mill cottages near the old Collins Company complex, where two or more appliances may share a single brick stack, we run a separate liner for each flue and smoke-test the entire stack to confirm no cross-contamination between neighbors. The sealed system is documented with photos you can see and a plain-English verdict. Done right - and we stand behind it.
Flexible Liner Installation
Some Collinsville chimneys have offsets or bends that make a rigid liner impossible to feed. A flexible liner navigates those turns while still giving you the full protection of a stainless steel venting system. We see this most often in the older two-story frame cottages where the chimney was built around a structural post or where previous modifications shifted the flue path. Our flexible liners are professional-grade, not the thin-wall builder-grade substitutes some operators use. We camera-inspect before and after installation so you see the fit.
Liner Replacement
If your existing liner is cracked, corroded, or was the wrong material from the start, a full replacement is the only safe option. In Collinsville, we regularly find clay tile liners that have shattered from thermal shock in flues oversized for modern appliances, or aluminum liners that have corroded through where gas exhaust condensed. The valley’s cold air pooling extends the burning season and keeps flue temperatures lower, which worsens condensation and corrosion. We remove the failed liner, camera-scope the remaining masonry, and install a new stainless system with a lifetime warranty on the material. The 90-Day Done Right Promise covers our workmanship in writing.
Partial Rebuild
When the upper courses, crown, or interior wythes of a Collinsville chimney have failed but the lower structure is sound, a partial rebuild preserves what is good and fixes what is not. This is common in the mill-village housing stock where hard Portland cement repointing from a past repair has accelerated cracking in the surrounding soft brick. We grind out the incompatible mortar and rebuild with lime mortar matched to the original 19th-century formulation - standard patching would worsen the damage. The crown is poured or capped with proper overhang and drip edge to shed water. Most partial rebuilds are completed in one visit.
Full Chimney Rebuild
A full rebuild is rare but necessary when the chimney has suffered catastrophic structural failure - extensive freeze-thaw damage, major settling, or fire damage that has compromised multiple wythes. In Collinsville’s oldest cottages, this sometimes follows years of deferred maintenance on a shared stack where multiple owners delayed action. We dismantle to sound masonry, salvage what original brick we can, and rebuild to current code with proper flue sizing and venting separation. The job is photographed at every stage, and the final system is smoke-tested and camera-verified.
Liner Repair
Minor liner damage - localized cracks, joint separation, or small gaps - can sometimes be addressed with HeatShield cerfractory resurfacing or targeted stainless patching. We do not recommend liner repair in Collinsville’s shared-stack situations unless we can verify that the entire flue system is intact and properly separated from neighboring appliances. Our Level-2 camera inspection gives us the evidence to make that call honestly, and we’ll tell you plainly when repair is sufficient and when replacement is the safer choice.

Common Chimney Liner & Rebuild Problems We See in Collinsville Homes
- Shared-stack cross-contamination in row cottages. Two or more appliances venting into one brick stack is common in Collinsville’s attached mill housing. Cracked mortar joints let one neighbor’s exhaust back-draft into another’s firebox. We smoke-test the entire stack, not just the flue we’re working on, because the hazard isn’t always where you expect it.
- Oversized flues glazing with third-degree creosote. Original soft-brick flues built for coal or wood are often too large for modern gas or oil appliances. Exhaust cools before it exits, condensing into glazed creosote that a standard brush won’t remove. The Farmington River valley’s pooled cold air extends this risk through a longer burning season than the hill towns see.
- Hard-cement repointing destroying soft brick. Past repairs with Portland cement on 150-year-old soft brick create a hardness mismatch. The cement doesn’t flex, so freeze-thaw cycles crack the surrounding brick instead of the joint. Standard patching over this damage accelerates spalling. We grind it out and use lime mortar.
- Intermittent downdraft from valley wind patterns. Collinsville’s channeled wind can pressurize chimneys unpredictably, especially on south-facing slopes near the river. This compounds venting problems in already-marginal systems and can drive combustion gases into living spaces even when the flue appears to draft normally.

FAQs - Chimney Liner & Rebuild in Collinsville
It can be made safe, but only if the entire shared stack is inspected and properly separated. We camera-scope all flues in the stack, smoke-test for cross-leakage, and install separate liners with sealed top plates so each appliance vents independently. On a row cottage off River Street near the old Collins Company complex, we found the neighbor’s oil furnace tied into the same soft-brick stack as the homeowner’s wood stove - a 130-year-old flue sized for coal, now asked to vent two appliances. We ran a Level 2 inspection, camera-scoped the shared stack, then installed a DuraFlex stainless liner with a sealed top plate and new chimney cap so the two flues stayed separate; the smoke test held. The hard-Portland repointing from a past repair was cracking the surrounding soft brick, so we ground it out and rebuilt the crown and upper courses in lime mortar rather than patching over it. Call (860) 743-1516 if you suspect your stack is shared - we’ll check it properly.
Original brick is the container, not the vent. Unlined brick flues leak combustion gases through mortar joints, allow creosote to soak into the masonry, and were sized for fuels your appliance doesn’t burn. In Collinsville, most 19th-century flues are oversized for modern gas or oil equipment, so exhaust cools and condenses before reaching the top. A liner creates a correctly sized, sealed venting path that protects the brick and your household. Call (860) 743-1516 for an inspection - we’ll show you the camera evidence.
Hard Portland cement was likely used instead of lime mortar. The cement is stronger than the 150-year-old soft brick, so freeze-thaw cycles crack the brick rather than the joint. Standard patching over this damage makes it worse. We grind out the incompatible mortar and rebuild with lime mortar matched to the original formulation. The fix costs more upfront than a patch, but it stops the cycle. Call (860) 743-1516 and we’ll assess whether your chimney needs this restoration.
Yes - especially in Collinsville, where the valley’s cold air pooling extends the burning season and where shared stacks and oversized flues create hazards independent of how often you light a fire. Oil and gas appliances vent year-round, and their exhaust can back-draft through cracked masonry even when your fireplace is cold. Our $89 seasonal tune-up includes a Level-1 inspection; if we find concerns, we’ll recommend a Level-2 camera inspection. Call (860) 743-1516 to schedule.
We dismantle to sound masonry, typically 18-36 inches below the failure point, then rebuild with matching brick and lime mortar, proper flue sizing, and a poured or capped crown with correct overhang. In Collinsville’s shared-stack row cottages, rebuilds sometimes require coordinating access with neighboring owners and temporarily capping their flue during construction. We photograph every stage, smoke-test the finished system, and warrant the workmanship under our 90-Day Done Right Promise. Most partial rebuilds complete in one visit; full rebuilds may take two. Call (860) 743-1516 for a free estimate and timeline.
