We’ve been driving to Millis since 1984, long enough to know the difference between a chimney off Village Street and one out near the Medway line. Russell Haines started this company with the belief that a homeowner deserves photos they can see and a verdict they can understand, not a scare tactic and a hard sell. That hasn’t changed in 42 years. When we say we’ll be there when we say, we mean it - and if something’s not right, we come back. In writing, no arguing.
Why Hearthstone Chimney Co. Is Millis’s Preferred Chimney Cleaning & Sweep Company
Millis is not a town you learn from a map. The post-war ranches along Route 109 carry different problems than the early colonials near the town center, and the river-valley humidity here works on mortar in ways drier towns don’t experience. We’ve cleaned chimneys on Main Street, swept flues off Elm Street, and documented liner failures in the split-levels near the Charles River watershed that a less experienced sweep might miss entirely.
Our technicians are background-checked, uniformed, and trained to complete most jobs in a single visit. We show up with the right equipment and professional-grade materials - HeatShield, Gelco, Olympia Chimney - so we’re not making a second trip because we didn’t bring what the job required. No-hassle upfront pricing means the number on the estimate is the number on the invoice. We’ve earned our reputation in Norfolk County one chimney at a time, and we plan to be here in thirty more years. That changes how you treat every job.
Calls are answered by a live person 24 hours a day, 7 days a week. Not a callback queue. Not an app. A person who can book you, answer your question, or dispatch a technician if the situation calls for it.
Our Chimney Cleaning & Sweep Services in Millis
Level 1 Inspection
A Level 1 inspection is the annual standard for chimneys in regular use with no changes to the system. In Millis, where many homeowners burn cordwood from November through March, we recommend this every year before the first fire. Our technician examines the readily accessible portions of the chimney exterior, interior, and connecting appliance, checking for creosote buildup, obstructions, and basic structural soundness. For the older colonials near the historic town center with unlined rubble-stone chimneys, this inspection often reveals mortar deterioration accelerated by the low-lying valley humidity - a local pattern we’ve documented across decades of service in Millis.
Level 2 Inspection
A Level 2 inspection goes deeper, and it’s required when you’ve changed your heating appliance, experienced a chimney fire, or are buying or selling a home. This is where our camera inspection proves its worth. We run a high-resolution camera through the flue, document every tile joint and every crack, and deliver photos you can see with a plain-English verdict. In Millis’s 1950s-1970s housing stock, we regularly find clay-tile liners with failed mortar joints and interior spalling caused by gas conversions venting into oil-sized flues - damage invisible from the roofline that a Level 1 inspection cannot catch. This is the inspection that saves you from a $4,000 surprise two winters from now.
Creosote Removal
Creosote is the reason chimneys catch fire. It builds in stages, from flaky soot to tar-like glaze to the hardened, fuel-dense third stage that requires mechanical removal. Millis’s sustained cold season means longer burn cycles, and homeowners who burn unseasoned hardwood or run wood stoves overnight accelerate buildup significantly. We remove creosote using professional-grade brushes, chains, and rotary systems matched to your flue diameter and liner material - never the wrong tool for the job. For glazed creosote, we apply specialized chemical treatments that break down the deposit before mechanical removal, protecting your flue from damage.
Soot Removal
Soot is lighter than creosote but no less problematic when it accumulates. It restricts draft, stains interior masonry, and can migrate into living spaces through the smallest gaps. In Millis homes with mid-century masonry chimneys serving both fireplace and furnace, soot from one appliance can contaminate the other’s flue, creating odor and draft problems that homeowners often misdiagnose. Our soot removal service includes HEPA-containment cleanup, protecting your home’s air quality while we work. We also handle Fireplace Services in Millis for homeowners needing deeper hearth restoration beyond standard cleaning.

Common Chimney Cleaning & Sweep Problems We See in Millis Homes
- Gas conversions in oversized oil flues. A technician working the older streets off Village Street regularly finds chimneys where a mid-century oil boiler was swapped for a high-efficiency gas unit but vented into the same oversized clay-tile flue - the flue never relined - leaving cool, wet exhaust condensing into the tile and causing interior spalling that looks clean from the roofline but is actively deteriorating from inside.
- Cracked clay tiles in 50-70-year-old liners. The post-WWII housing belt along Route 109 and surrounding roads is full of chimneys with clay-tile liners now at the end of their reliable lifespan. Cracked tiles shift, open gaps in mortar joints, and allow exhaust to reach surrounding masonry - a problem our Level 2 camera inspection catches before it becomes a rebuild.
- Mortar erosion from river-valley humidity. Millis sits in the Charles River watershed where sustained moisture accelerates mortar joint failure and moss growth on exterior chimney masonry. This shortens maintenance cycles compared to drier inland communities and makes annual inspection more critical, not less.
- Mixed creosote and condensation deposits in dual-use chimneys. The dual-flue and shared-chase configurations common to Millis’s mid-century stock create conflicting draft pressures. When a wood-burning fireplace and a converted gas furnace share a chimney chase, the temperature differentials produce unusual deposit patterns that require experienced diagnosis.
