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.

We’ve been dispatching crews to New Fairfield from our Hartford office for decades, and we know the chimneys here better than most. The town’s split personality matters: mid-century ranches and colonials inland with straightforward clay-tile flues, and the real challenge - the Candlewood Lake shoreline cottages, those 1930s to 1960s seasonal builds that got converted to year-round living without anyone upgrading the chimney to match. That’s where the industry’s worst upselling happens, and it’s exactly where our camera-first approach earns its keep. Nothing gets quoted without photos you can see and a plain-English verdict you can understand.
Why Hearthstone Chimney Co. Is New Fairfield’s Preferred Chimney Liner & Rebuild Company
We’ve served Connecticut homeowners for over 42 years, and our reputation in New Fairfield was built one shoreline cottage at a time. The 90-Day Done Right Promise isn’t marketing language - it’s in writing, no arguing, governed by our K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it. If it’s not right, we come back. Simple as that.
Our Level-2 camera inspections end with photos on a tablet and a verdict spoken in plain English, not contractor jargon. You’ll see the spalled clay tile, the glazed creosote, the missing mortar joint yourself. Then we price the job upfront - the number on the estimate is the number on the invoice. Background-checked, uniformed technicians handle most liner and rebuild jobs in a single visit, and a live person answers the phone 24 hours a day, 7 days a week. No voicemail, no callback queue.
We coordinate scheduling from our Hartford office, but our crews are in New Fairfield regularly - particularly through Sherman and along Route 39 toward the lake. We know which cottage clusters were built in the 1940s with no footings under the chimney breast, and which 1950s ranches on Ball Pond Road have the original terracotta flue tiles that are finally giving out. That local knowledge saves time and prevents the wrong fix.
Our Chimney Liner & Rebuild Services in New Fairfield
Stainless Steel Liner Installation
For New Fairfield homeowners with intact clay-tile flues that have cracked or shifted, a stainless steel liner is often the right move. We size the liner to your appliance - not guess - using the manufacturer’s BTU rating and the flue’s interior dimensions. In the lake cottages, this matters enormously: a 1950s fireplace converted to a wood stove needs a liner sized to the stove, not the original firebox. We use DuraFlex and Olympia Chimney products, installed to NFPA 211 standards, with the smoke chamber parged and the top resealed.

Flexible Liner Systems
Flexible liners are our most common solution in New Fairfield’s converted cottages, and for good reason. Many of these chimneys have offset flues, narrow terracotta channels, or slight bends that rigid pipe simply won’t navigate. A DuraFlex flexible liner conforms to the existing path while giving you the full stainless rating you need for wood, pellet, or gas appliances. We see this constantly on the Candlewood Lake properties - a 1960s cottage with a chimney built for a summer fireplace, now feeding a high-efficiency insert that runs six months a year. The flexible liner solves the geometry problem without tearing down walls.

Liner Replacement
When an existing liner has failed - corroded stainless, collapsed clay tile, or a previous install that was never properly sealed - we extract and replace. In New Fairfield, liner replacement often follows the discovery that a previous owner “got by” with a shortcut: an insert dropped in with no liner at all, or a flexible liner that was undersized and has now burned through. We camera the full length, document the damage with photos, then pull the old material and set new. The job includes a new top plate, insulation where required by code, and a written warranty.

Partial Chimney Rebuild
Not every failing chimney needs to come down to the roofline. A partial rebuild targets the damage: the crown that’s cracked and letting water into the stack, the top courses where mortar has turned to sand, the firebox walls that have spalled from heat and moisture. In New Fairfield’s shoreline cottages, we rebuild crowns and upper stacks more often than full chimneys - the original seasonal construction used minimal crown overhangs and no drip edges, so water has been working on the mortar for sixty years. We re-lay with proper bond, cast a new crown with positive pitch and drip detail, and flash to the roofline. Done right, and we stand behind it.

Trusted Brands We Service in New Fairfield
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, HeatShield, Gelco, and Copperfield - the brands that other sweeps order when they get a job they can’t handle with hardware-store stock. For New Fairfield customers, this means faster turnaround: we don’t need to special-order a liner or a crown form, because it’s already on the shelf. A HeatShield cerfractory flue repair, a Gelco cap, a DuraFlex flexible run - we size it, cut it, and install it. No waiting, no substitutions, no surprises on the bill.
Common Chimney Liner & Rebuild Problems We See in New Fairfield Homes
- Unlined cottage flues with forced-in inserts. The 1980s and 1990s conversion boom dropped wood stoves and inserts into 1950s cottage fireplaces with no liner relining whatsoever. The appliance vents into unlined brick or a clay tile never sized for the load. Within three to five seasons, third-degree creosote glazes the flue and the undersized passage starts smoking into the room. We camera every one.
- Clay-tile spalling from shoreline moisture cycling. Candlewood Lake adds ambient humidity that condenses inside chimneys sitting cold all summer. Come October, the first hard firing flash-dries the surface and the clay face pops off. We’ve pulled tile shards the size of poker chips from flues on Sail Harbour and Candlewood Isle that looked fine from the hearth.
- Crowns and flashing that were minimal or absent from original construction. Seasonal cottages didn’t need elaborate chimney protection - they were empty November through April. Once converted to year-round use, water enters through cracked wash layers or missing flashing, rots mortar from the inside, and turns the stack into a sponge. The damage hides until the camera goes up.
- Mortar joints crumbled by freeze-thaw in the hill country. New Fairfield sits higher and colder than coastal Fairfield County. More freeze cycles, longer heating seasons, and harder thermal shock to masonry that was never built for it. We see this particularly on inland colonials near Pootatuck State Forest, where the chimney runs exterior on two sides.

FAQs - Chimney Liner & Rebuild in New Fairfield
Yes, absolutely, and anyone who quotes a liner price without camera evidence is selling blind. We were out on Candlewood Lake’s shoreline cottages last fall and pulled a Famco insert out of a 1950s cottage fireplace that had been dropped in during a conversion with no stainless liner behind it - the flue was unlined brick, third-degree creosote glazed down past the damper, and the clay tile above it had spalled from years of shoreline moisture. We ran a camera, walked the homeowner through the footage, then set a DuraFlex flexible liner sized to the insert and re-cast the smoke chamber and crown; by January the stove was drafting hard instead of smoking into the room. The camera tells us whether you need a liner, a partial rebuild, or just a thorough sweep. Call (475) 375-9457 to schedule - estimates are free.
A full rebuild is only necessary when the structural masonry has failed - leaning stack, separated courses, or mortar turned to sand throughout. Most New Fairfield chimneys need a liner, a crown repair, or a partial rebuild of the upper stack, not a teardown. We determine this with a Level-2 camera inspection and exterior assessment, documented with photos you can see. If the flue is sound but unlined, a stainless or flexible liner is the right fix. If water has rotted the top courses but the base is solid, we rebuild from the roofline up. We never recommend more work than the evidence supports. Call (475) 375-9457 for a free inspection and plain-English verdict.
New Fairfield’s hill-country location means colder winters, longer heating seasons, and more frequent cold starts - all conditions that produce creosote. The Candlewood Lake shoreline adds a specific problem: ambient moisture condenses inside chimneys that sit cold and damp through summer, then the first October firing flash-evaporates that moisture and leaves a sticky, acidic film that accelerates buildup. Coastal chimneys in Bridgeport or Stamford don’t see the same moisture cycling, and they don’t run as many hours per season. In New Fairfield, we recommend annual sweeping for any wood-burning appliance, and camera inspection every two to three years for converted cottages. Call (475) 375-9457 to book.
First-degree creosote is dry, flaky soot - easy to sweep, low risk. Third-degree is shiny, hardened tar that bonds to the flue surface and becomes its own fuel source. It forms when wood burns cool and moist, which is exactly what happens in an undersized or unlined flue: the smoke cools too quickly, condenses, and bakes on. Third-degree creosote can’t be brushed off with standard tools; it requires rotary removal or chemical treatment, and it’s the leading cause of chimney fires. For New Fairfield’s converted cottages with unlined flues, third-degree buildup is the warning that the flue is dangerously mismatched to the appliance. We camera, measure, and size a proper liner to eliminate the conditions that create it. Call (475) 375-9457 for an inspection.
Even a decorative fireplace needs a sound flue if there’s any chance of use - a holiday fire, a power outage, a new owner who doesn’t know it’s “decorative.” In New Fairfield’s older cottages, we often find that the “decorative” fireplace was actually the primary heat source for decades and has significant creosote or mortar damage hidden above the damper. If the flue is truly never used and the homeowner wants to seal it, we can advise on proper capping and ventilation. But we won’t sign off on an unlined or damaged flue as “fine because it’s decorative” - that’s how surprises happen. Camera first, then decide. Free estimates at (475) 375-9457.
