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.

Why Hearthstone Chimney Co. Is Collinsville’s Preferred Fireplace Services Company
We’ve been serving the Collinsville area for over 42 years, and in that time we’ve learned that the mill-village chimneys along the Farmington River corridor behave differently from anything you’ll find in the hilltowns. The soft brick, the hard-cement repointing, the unlined coal-stove flues - these aren’t textbook cases for us. We’ve documented hundreds of them with camera footage and plain-English verdicts that homeowners in Collinsville can actually use.
Our Fireplace Services team doesn’t guess. Every technician is background-checked and uniformed, and every job starts with a camera inspection and ends with photos you can see. Most repairs are completed in a single visit, with no-hassle upfront pricing - the number on the estimate is the number on the invoice. And everything we do is backed by our 90-Day Done Right Promise in writing: if it’s not right, we come back, no arguing, no paperwork.
Calls are answered by a live person, 24/7. Not a callback queue. Not an app.
Our Fireplace Services in Collinsville
Wood Burning Fireplace Service
Collinsville’s extended wood-burning season - the Farmington River valley traps cold air that lingers weeks longer than on the Canton hilltops - means more fires and more creosote. But here’s the real problem in these mill cottages: the original flues were sized for coal stoves and are often oversized for modern wood-burning appliances. An oversized flue runs cold, and a cold flue promotes third-degree creosote glazing that a standard brush won’t touch. We prove it with a camera before we recommend anything. If the glazing is there, we’ll show you. If a standard sweep is enough, we’ll tell you that too.
Fireplace Insert Installation & Service
Putting a gas or wood insert into an original Collinsville coal-stove flue without proper sizing and lining is how you get exhaust odors, failed draft tests, and worse. We measure the flue, match the liner to the appliance, and document the connection with camera footage. Our inserts and liners use professional-grade materials from HeatShield and Olympia Chimney - no builder-grade substitutes. Done right, an insert turns an unlined century-old flue into a safe, efficient heating source. Done wrong, it’s a venting mismatch waiting to become a problem.
Firebox Repair
The firebox in a 19th-century Collinsville fireplace wasn’t built with modern refractory panels. It was brick, laid with lime mortar, and it’s taken 130-170 years of direct heat. We assess whether the firebox needs repointing with period-appropriate materials, refractory panel replacement, or partial rebuild. For historic homes near the old Collins Company complex, we match repairs to the original construction method - hard Portland cement has no place in a soft-brick firebox, and we’ll explain why if we find it.
Gas Fireplace Service
Gas fireplaces in Collinsville’s converted mill cottages often vent into flues that were never designed for them. We see this constantly: a gas insert or direct-vent system connected to a coal-stove chimney with no liner, or a liner that’s the wrong diameter for the BTU output. Our service includes combustion analysis, draft testing, and camera verification of the venting path. If the flue is too large or too damaged, we’ll show you the footage and explain your options.
Damper Repair & Replacement
A damper that won’t open fully or seal properly wastes heat and can create dangerous backdraft conditions, especially in Collinsville’s valley location where wind patterns already challenge draft performance. We repair and replace throat dampers and top-sealing dampers, always verifying operation with a smoke test or draft gauge. No guesswork.
Fireplace Conversion
Converting a wood-burning fireplace to gas - or vice versa - in a Collinsville historic home requires more than a new burner and a log set. The flue must be sized to the new appliance, the firebox must handle the changed heat pattern, and the venting must be camera-verified. We handle the engineering and the paperwork, and we explain every step before we start.
Trusted Brands We Service in Collinsville
We stock parts and materials from professional-grade brands that hold up in Collinsville’s demanding conditions - HeatShield for ceramic resurfacing, Gelco for caps and dampers, and Olympia Chimney for liners and components. No builder-grade substitutes. Because our Hartford office maintains local inventory, most Collinsville repairs don’t wait on shipping. When we find spalled brick or a failed crown during your inspection, we can often return and complete the repair within days, not weeks.
Common Fireplace Services Problems We See in Collinsville Homes
- Hard-cement repointing destroying soft historic brick. Someone before you repointed the chimney with Portland cement. It looks solid, but it’s trapping moisture and spalling the surrounding brick. The chimney keeps failing because the repair material is harder than what it’s repairing. We remove it and restore with lime mortar.
- Unlined coal-stove flues venting modern appliances. The original flue was sized for a coal stove or furnace. Your gas insert or oil burner needs a smaller, properly sized liner. Without one, you get poor draft, exhaust odor, and accelerated deterioration. We prove the mismatch with a camera.
- Third-degree creosote glazing in oversized wood-stove flues. The flue is too big, runs too cold, and the creosote hardens into a glazed layer that standard sweeping won’t remove. We’ll show you the camera footage and explain whether mechanical removal or a chemical treatment is appropriate.
- Valley downdraft accelerating draft problems. Collinsville’s channeled wind patterns push smoke and exhaust back down chimneys that already draft poorly due to flue sizing issues. We diagnose the interaction between weather patterns and chimney geometry, then fix the root cause.

FAQs - Fireplace Services in Collinsville
They fail differently, not necessarily faster - but the failures are harder to patch. Collinsville’s 1840s-1890s soft-brick chimneys were built with lime mortar and later repointed with hard Portland cement by well-meaning contractors who didn’t understand the material mismatch. That hard cement traps moisture, accelerates spalling, and cracks the surrounding brick. Meanwhile, the hilltowns of Canton and Simsbury built harder-brick chimneys in the 20th century with compatible mortars. A Collinsville chimney needs lime-mortar restoration and careful matching of materials, not another layer of cement. Call (860) 743-1516 and we’ll show you exactly what your chimney is built with.
We do both, depending on what the camera inspection reveals. If the firebox brick is sound but the mortar joints have eroded, we repoint with period-appropriate lime mortar. If the rear wall has cracked or the firebrick has spalled from decades of direct heat, we install custom-fitted refractory panels or rebuild with firebrick matched to the original dimensions. We never recommend a rebuild when resurfacing will suffice, and we prove the condition with photos before we quote either option. Call (860) 743-1516 for a free estimate.
Only with a properly sized stainless steel liner installed from top to bottom. The original coal-stove flues in Collinsville’s mill cottages are almost always too large for modern appliances, and venting a gas or wood insert into an unlined oversized flue creates draft failure, creosote buildup, and potential carbon monoxide hazards. We measure the appliance output, calculate the correct liner diameter, and install it with a proper connector and insulation. The camera footage proves the liner is continuous and correctly seated before we sign off. Call (860) 743-1516 to discuss your specific fireplace.
No. Every repair recommendation we make at a Collinsville home is backed by dated, labeled photos or video from our Level 2 inspection. If we tell you the flue is unlined, you’ll see the bare brick. If we point out hard-cement damage, you’ll see the spalling and the crack pattern. If we say third-degree creosote is present, you’ll see the glazed, tar-like surface on the camera monitor. No exceptions. The 90-Day Done Right Promise applies to everything we do, but we prefer to prevent disputes by showing you the evidence before you spend a dollar.
Watch for exhaust odors when appliances run, smoke spillage when you light a fire, white efflorescence or missing mortar on the exterior brick, and any new cracks in the firebox or hearth. In Collinsville’s valley climate, also note if your wood-burning season seems to produce more creosote odor than usual - the cold, damp air here can mask draft problems until they become serious. If you notice any of these, don’t wait for your annual appointment. Call (860) 743-1516 and we’ll schedule a camera inspection.
