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 know Waltham chimneys. Not in the abstract. We know that a fireplace in a 1910 worker cottage on Charles Street behaves differently than one in a 1970s split-level off Lexington Street. Our Chimney Cleaning & Sweep crews work across Waltham every week, and we schedule by neighborhood so a truck that’s already in the Highlands can reach you the same morning. No dispatch call center, no “someone will call you back.” A live person answers.
Why Level Two Chimney Boston Is Waltham’s Preferred Chimney Cleaning & Sweep Company
Waltham homeowners call us because we show them what we found. That’s the entire point of the name. Every visit includes a camera down the flue and a photo record you keep, so when we say a clay tile liner is spalling behind the damper, you’re looking at the crack on a tablet screen, not taking someone’s word for it.
Corrine Halstead runs our Boston operation, and she’s built our Waltham book the slow way: one triple-decker at a time, usually by referral from a neighbor who watched us work. We’re not the cheapest sweep in Waltham and we don’t try to be. We’re the one that hands you a written scope and a written warranty before the brush goes up, because Clause 1 of the Haven Standard requires a written price before any work starts. Clause 4 requires the photo record. That’s been our practice since 2009, and it’s why property owners around Brandeis and the Route 128 corridor call us when a chimney issue threatens a closing.
Our technicians are background-checked, uniformed, and assigned by name. You’ll get a text when they’re on the way from our Boston dispatch office to your Waltham address. And every job, from a simple annual sweep to a full liner evaluation, is backed by the 365-Day Done Right Promise. If it’s not done right, we make it right.
Our Chimney Cleaning & Sweep Services in Waltham

Here’s what we actually do in Waltham homes, week in and week out.
Level 1 Inspection
A Level 1 inspection is the baseline check we run alongside every cleaning in Waltham. We’re looking at the accessible portions of the firebox, the damper, the smoke chamber, and the flue from both ends. For a typical South Side cottage with a well-maintained fireplace and no history of problems, this is almost always the right scope.

Level 2 Inspection
A Level 2 inspection is the camera-scan standard we default to on Waltham’s older chimneys, especially in triple-deckers and converted coal flues. If you’re buying a home near Moody Street, selling one in the Highlands, or your fuel source changed from oil to gas at some point in the last 40 years, this is the inspection that actually shows liner condition. We run the camera from the crown down through the smoke chamber. You watch the video. You keep the stills.

Creosote Removal
Creosote removal isn’t just brushing. In Waltham’s older flues, we frequently find first-degree creosote buildup even in gas-only chimneys, because oversized original flues cool exhaust too quickly and condensation does the rest. When we find heavier deposits, we use rotary whip systems sized to the tile liner so we don’t crack old clay while removing the glaze.

Soot Removal
Soot is the powdery black residue from incomplete combustion, and in Waltham’s converted coal chimneys it tends to cake the smoke chamber and throat before it ever shows up in the firebox. We clean the entire path, not just what you can see from the living room. That’s the difference between a sweep that lasts a season and one that lasts five minutes.
We also handle your Annual Sweep and full Fireplace Cleaning as part of a single visit. Call (857) 567-8887 and we’ll scope it in writing before we schedule the truck.

AfterTrusted Brands We Service in Waltham
When a Waltham chimney needs more than a cleaning, we install and service liners and components from manufacturers we trust: Gelco and Olympia Chimney for caps and terminations, Famco for vents and dampers, Copperfield for chase covers and flashing components. We don’t carry cheap generics. We stock these because they hold up through a New England heating season and because their dimensions are predictable, which matters when you’re fitting a liner into a 1905 flue that’s drifted half an inch out of square.
Common Chimney Cleaning & Sweep Problems We See in Waltham Homes

- Converted coal flues venting modern gas appliances. Waltham’s Watch City housing stock was built for coal. A flue originally sized for a coal furnace is often far too large for a 60,000 BTU gas burner, which drops exhaust temperatures and accelerates creosote or condensation buildup. We see this constantly in triple-deckers around Moody Street.
- Spalling clay tile liners in pre-1930 chimneys. Water penetration plus six months of heat cycling per year breaks down old clay tiles from the inside. By the time pieces show up in the firebox, the liner has already been failing for years. A camera inspection shows it early.
- Shared flues venting multiple units’ appliances. A single original masonry flue built for one coal furnace now venting a gas furnace and a water heater for two separate units is a configuration that typically violates Massachusetts 248 CMR liner-sizing rules. This surfaces as a deal-killing defect during rental-property turnover near Brandeis.
- Freeze-thaw damage to crowns and flashing. Waltham sits in the Charles River valley and gets real winter. Ice damming on roof lines along Lexington Street and the Highlands routinely compromises flashing and drives water into liners between cleanings, which is why we recommend an annual inspection even when you barely use the fireplace.

We always write the price down before work begins. Always. If a competitor quoted you something else, bring us their written estimate.

FAQs - Chimney Cleaning & Sweep in Waltham

A camera inspection is essential because Waltham’s pre-1930 chimneys were built for coal, and the only way to know whether the flue is still structurally safe is to look at it from the inside. A visual check from the firebox or the roof misses spalling tile, separated joints, and hidden gaps behind the smoke chamber. If the liner is deteriorated and we clean with standard brushes anyway, we can make the problem worse. In Waltham’s older stock, we don’t sweep a flue we haven’t seen. The camera image is the record, and you keep it. Call (857) 567-8887 to schedule a Level 2 inspection with your next cleaning.
Even gas-only chimneys in Waltham should be inspected annually and cleaned when deposit buildup or moisture issues show up. Gas exhaust is cooler than wood smoke and condenses readily inside oversized original flues, which produces acidic soot and first-degree creosote-like deposits even without a single log ever burned. We’ve documented this repeatedly in converted coal flues near Moody Street and the South Side. An annual sweep with a camera check costs less than a single repair. Call (857) 567-8887 and we’ll set a written scope before we schedule.
Usually not, and this is the most common code violation we find in Waltham rental stock. A single flue originally built for one coal furnace in a late-Victorian triple-decker is now often venting a gas furnace and a gas water heater for two separate units. Massachusetts 248 CMR has specific liner-sizing and common-venting rules, and most of these configurations violate them. The practical risk is backdrafting: exhaust from one unit pushing into the other’s living space. We document the configuration with our camera, explain what the code requires, and give you a written recommendation. Whether you act now or later, you’ll know exactly what exists. Call (857) 567-8887 for a Level 2 inspection.
Third-degree creosote is a tar-like glaze that hardens into a shiny, rock-hard layer and will not come out with standard sweeping brushes. It’s also the most flammable form of creosote. In Waltham, we typically find it in chimneys that vented coal for decades before converting to wood or gas, or in wood-burning fireplaces that ran for years without cleaning. We use rotary removal systems sized to the existing tile liner, removing the glaze without cracking the old clay. Then we run the camera again to confirm the flue is clean and unbroken. You get before and after photos. If you have a wood fireplace in a pre-1930 Waltham home, call (857) 567-8887 and we’ll scope it in writing.
Yes, and it’s more aggressive here than in towns farther from the Charles River valley. Waltham’s elevation and river-valley position mean sustained freeze-thaw cycles all winter. Water gets into hairline mortar joints, freezes, expands, and breaks the bond. Ice damming on roof edges, common along the Highlands and streets off Lexington Street, backs water up under flashing and into the chimney chase. The result is more spalling, more liner damage, and more rusted dampers than you see in sheltered inland communities. An annual inspection catches it before one more winter makes it a full rebuild. Call (857) 567-8887 and get a written price.
