Worth knowing

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 answering calls with a live person, 24 hours a day, for over 42 years. Russell Haines built Hearthstone Chimney Co. on a simple principle: show the homeowner what you found, explain it in plain English, and put your promise in writing. That hasn’t changed. Our technicians are background-checked, uniformed, and trained to document every inspection with photos you’ll see before any work is approved. No surprises on the bill. The number on the estimate is the number on the invoice.

New Milford is different from the towns around it. Connecticut’s largest municipality by land area, it stretches across rural ridges and river valley in ways that matter for your chimney. Homes off Long Mountain Road or in the northern reaches burn wood as primary heat through winters that run colder and longer than coastal Connecticut. That reality changes how fast creosote builds, what kind of creosote forms, and how often you actually need us out.

Why Hearthstone Chimney Co. Is New Milford’s Preferred Chimney Cleaning & Sweep Company

We know the difference between a chimney in the historic district near the Village Green and one heating a farmhouse off Route 7. The former might be 200-year-old rubble-stone with no clay liner. The latter might have a stainless steel insert working hard six months straight. Our Chimney Cleaning & Sweep team treats them differently because they are different.

New Milford homeowners call us because we’ve earned a reputation for saying what needs doing and what can wait. Our 90-Day Done Right Promise, backed in writing with no arguing, means if something isn’t right, we come back. No paperwork chase. No “we’ll get to it next week.” The K.E.Y.S. code governs everything: Krafted right, Every time, Your home first, Standing behind it.

Dispatch and scheduling are coordinated from our Hartford office, but crews serve New Milford locally. Most jobs finish in one visit. Calls don’t go to voicemail or a callback queue. A live person answers, every hour of every day. That’s not a marketing claim. It’s how we’ve operated since 1984.

Our Chimney Cleaning & Sweep Services in New Milford

Annual Sweep

For most New Milford homes burning seasoned cord wood on weekends, an annual sweep clears first-degree creosote, a light, flaky deposit that brushes away clean. But if you’re running a wood stove hard through the valley’s extended heating season, or burning your own cut wood, we may recommend a six-month interval. On a call off Long Mountain Road in the rural northwestern part of town, our tech pulled the pipe on a wood stove that had run all winter on the homeowner’s own unseasoned red oak and found the flue liner coated in sticky, corrosive third-degree creosote that a standard brush wouldn’t touch. We had to apply a chemical creosote remover and re-sweep before the damper would even seat properly. The firebox and smoke chamber were just as bad, so we recommended switching to seasoned cord wood and booked a follow-up sweep in six months instead of the usual annual visit. That’s the honest assessment you get from us. A square deal.

Annual Sweep

Level 1 Inspection

Included with every standard sweep, a Level 1 inspection covers readily accessible portions of your chimney structure and flue. For New Milford’s mid-century ranch and cape cod homes built through the 1960s and 70s, this often suffices if the system hasn’t changed and you’re burning properly seasoned fuel. We check for obstructions, creosote buildup, and basic structural soundness. If we find anything that needs a closer look, we’ll show you the photo and explain why before recommending a Level 2.

Level 1 Inspection

Level 2 Inspection

New Milford’s older housing stock demands this more than most towns. Colonial and Federal-era antiques near the historic Village Green, some dating to the 1700s and 1800s, frequently have original rubble-stone and brick chimneys with no properly sized clay tile liner. A Level 2 camera inspection lets us see what we can’t reach from the hearth: mortar joint deterioration, liner gaps, hidden creosote glazing, and crown damage from freeze-thaw cycling. You get photos you can see and a plain-English verdict. Nothing is recommended without camera evidence. If work can safely wait, we’ll say so. That’s the Keystone Standard.

Level 2 Inspection

Creosote Removal

Because New Milford is Connecticut’s largest town by land area and its rural northern and western sections routinely burn home-cut green or mixed hardwood all winter, we find third-degree, tar-glazed creosote after a single season in flues that would only reach first-degree in denser towns like Brookfield or Danbury. This isn’t a scare tactic. It’s physics. Green wood burns cooler, producing more incomplete combustion. The resulting creosote is black, shiny, and tar-like. It won’t brush out. It requires chemical treatment, mechanical removal, or both. Left alone, it ignites at lower temperatures and burns far hotter than first-degree deposits. For homes in Gaylordsville, Northville, or along the ridge roads west of the Housatonic, creosote removal is often the most critical service we provide.

Creosote Removal

Soot Removal

Less hazardous than creosote but still worth addressing, soot accumulation reduces draft efficiency and can recirculate fine particulates into living spaces. We see this particularly in New Milford homes that have converted to gas inserts but never had the original flue properly cleaned. Soot removal is straightforward, but it still gets the same documentation: photos, verdict, your approval before we proceed.

Trusted Brands We Service in New Milford

We don’t use builder-grade substitutes. For liner repairs and relining in New Milford’s unlined antique chimneys, we specify HeatShield refractory mortar systems and DuraFlex stainless steel liners rated for the heavy use these homes see. For crown and masonry repair damaged by the valley’s freeze-thaw cycling, we source professional-grade materials from Copperfield and Gelco. These are the brands that hold up when a New Milford winter runs six months. We stock common parts locally, so most repairs don’t wait on shipping. Done right, and we stand behind it.

Common Chimney Cleaning & Sweep Problems We See in New Milford Homes

  • Third-degree creosote in single-season flues. Homeowners burning green or mixed home-cut hardwood all winter assume a once-a-year sweep is enough, but the heavy, sticky creosote here can hit third-degree in a single season and won’t come off with a brush alone. We find this regularly on calls to rural northern and western New Milford, where wood stoves function as primary heat.
  • Unlined antique masonry near the Village Green. Colonial and Federal-era chimneys in the historic core often lack a properly sized flue liner, so even a routine sweep can’t make them safe once heavy fall burning resumes without a HeatShield or liner upgrade. We document this with camera evidence and explain exactly what you’re looking at.
  • Crown and brick spalling from valley freeze-thaw. Situated in the Housatonic River valley with higher terrain surrounding, New Milford experiences more aggressive freeze-thaw cycling than lower-elevation southwestern Connecticut towns. Cracks in the crown let moisture accelerate creosote corrosion and create draft problems that show up as smoky fires or cold air returns.
  • Improperly seasoned fuel accelerating corrosion. Technicians working the rural stretches regularly find wood stoves that have run all winter on green or mixed hardwood cut from the homeowner’s own land. This local practice produces far more corrosive, sticky creosote than seasoned purchased cord wood, and often means a single-season flue that looks like it hasn’t been touched in five years.
