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 working on Chimney Cleaning & Sweep in Belmont long enough to know the pattern. The town’s early-20th-century Colonials and Victorians, especially up on Belmont Hill, have chimneys that were built for a different era. Coal furnaces, oil boilers, wood fireplaces - the flues were sized for those fuels. Now most homes run gas appliances vented into those same oversized, often unlined stacks. That mismatch is the root of most problems we find. Our Chimney Cleaning & Sweep team doesn’t guess. We camera-inspect before we clean or recommend anything, and we show you the photos.
Why Hearthstone Chimney Co. Is Belmont’s Preferred Chimney Cleaning & Sweep Company
Belmont homeowners tend to stay put. They’ve owned their houses for twenty, thirty, forty years. They’ve also had contractors in who recommended work that didn’t need doing, or skipped work that did. We understand that history. Russell Haines built Hearthstone Chimney Co. in 1984 on the principle that a craftsman explains what he sees, shows the evidence, and lets the homeowner decide. Forty-two years later, that hasn’t changed.
Our Boston office dispatches crews to Belmont daily. We know the difference between a flat near Pleasant Street and a hilltop stack on Belmont Hill exposed to the wind. We know which neighborhoods have the original clay tile liners, which have had conversions with questionable shared flue connections, and which chimneys have been neglected since the oil-to-gas switch in the 1970s. That local knowledge saves you from unnecessary work and catches problems that a generic sweep would miss.
Every call is answered by a live person, 24 hours a day. Our technicians are background-checked, uniformed, and carry the tools and materials to complete most jobs in a single visit. Pricing is agreed upfront. 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, no arguing.
Our Chimney Cleaning & Sweep Services in Belmont
Level 1 Inspection
A Level 1 inspection is the standard annual check for chimneys with no changes to the system and no known problems. In Belmont, this covers most homeowners who burn wood occasionally in a fireplace that’s been inspected within the last year. We examine the readily accessible portions of the chimney exterior, interior, and connections. We check for creosote buildup, obstructions, and basic structural soundness. For Belmont homes with straightforward single-flue systems and recent maintenance history, this is often sufficient. Cost: $180-$250.

Level 2 Inspection
This is where Belmont’s housing stock demands more. A Level 2 inspection includes everything in Level 1, plus a camera scan of the full flue interior. In Belmont, we strongly recommend Level 2 for any home with a multi-flue chimney, any home that has converted from oil or coal to gas, and any home on Belmont Hill with downdraft complaints.
Here’s why. On a Belmont Hill Colonial Revival, our tech found a single large stack with an abandoned coal-furnace flue, an active gas-appliance flue, and a fireplace flue all sharing one crown with no labels, plus first-degree creosote in the fireplace flue and visible spalling in the clay tile liner of the gas flue. We ran a Level 2 inspection with the camera so the homeowner could see every flue, brushed the fireplace flue only after confirming the shared connections, and set our Chimney Liner & Rebuild in Belmont plan for the deteriorating gas flue rather than quoting a full rebuild sight-unseen. The home’s downdraft complaint traced to a missing chimney cap at the wind-exposed stack top, not to the fireplace.
Without that camera evidence, a homeowner might have paid for a full relining they didn’t need, or worse, missed a deteriorating gas flue venting carbon monoxide into the home. Level 2 inspection in Belmont: $250-$400.

Creosote Removal
Creosote builds up in fireplace flues with every wood-burning fire. First-degree creosote is flaky and brushes off easily. Second-degree is shiny and tar-like, requiring more aggressive tools. Third-degree is hardened glaze, the most dangerous and hardest to remove. In Belmont, we see a lot of first-degree creosote in occasional-use fireplaces and second-degree in homes that burn regularly through the winter.
Belmont’s freeze-thaw cycles make creosote removal especially important. Moisture seeps into masonry cracks, expands when it freezes, and opens pathways for creosote acids to attack the liner. A clean flue is a dry flue. We use professional-grade rotary brushes and vacuum systems, and we never leave debris in the firebox or living space. Standard creosote removal with sweep: included in base pricing. Heavy third-degree removal: $320-$480.

Soot Removal
Gas appliances produce soot, not creosote, but the accumulation still restricts draft and can indicate improper combustion. In Belmont’s converted homes, we often find soot-clogged flues where a high-efficiency gas boiler was vented into an oversized chimney never designed for the cooler exhaust temperatures. The result is condensation, corrosion, and blocked draft. We remove soot deposits, inspect for corrosion damage, and document any liner deterioration with photos you can see. Soot removal with inspection: $180-$280.

Annual Sweep
The National Fire Protection Association recommends annual inspection for all chimneys, and sweeping as needed based on use. In Belmont, we recommend annual service for any wood-burning fireplace and biennial for gas-only systems in homes with good maintenance history. The annual sweep includes the inspection, cleaning, and a written condition report with photos. We schedule Belmont sweeps before burning season, typically September through November, though we work year-round. Annual sweep with Level 1 inspection: $180-$320.

Fireplace Cleaning
Fireplace cleaning addresses the firebox, smoke chamber, damper, and visible flue. In Belmont’s older homes, we frequently find degraded mortar in the smoke chamber, stuck or missing dampers, and fireboxes coated with years of ash residue. We clean thoroughly and report what we find. Fireplace cleaning with inspection: $200-$340.

Common Chimney Cleaning & Sweep Problems We See in Belmont Homes
- Multi-flue stacks with no labeling. A single large chimney on Belmont Hill often contains two or three flues - one abandoned coal-furnace flue, one active gas-appliance flue, and one fireplace flue - with no indication which is which. Companies clean or recommend work on the wrong flue, or miss an active problem entirely. We camera-inspect first. Every time.
- Downdraft misdiagnosed as fireplace failure. Belmont Hill’s taller stacks catch stronger prevailing winds than the flats below. Homeowners call us complaining of smoky fireplaces, and previous contractors have replaced dampers or rebuilt fireboxes unnecessarily. Often the real problem is a missing or improper chimney cap, or a flue termination too low for the wind exposure. We find the actual cause.
- Accelerated liner spalling from freeze-thaw cycles. Eastern Massachusetts winters hit Belmont hard. Water enters cracks in aging mortar, freezes, expands, and spalls clay tile liners. Gas exhaust, cooler and wetter than coal or oil exhaust, condenses in the oversized flue and accelerates the damage. Annual inspection catches this before it becomes a carbon monoxide hazard.
- Unlined or improperly lined gas flues. When Belmont homes converted to gas, many installers vented new appliances into existing chimneys without proper liners. The old flue is too large, the exhaust too cool, and the result is condensation, corrosion, and draft failure. We document the condition with camera photos and recommend liner installation only when the evidence supports it.

FAQs - Chimney Cleaning & Sweep in Belmont
Yes. We camera-inspect every multi-flue chimney before cleaning or recommending any work. On Belmont Hill especially, we regularly find unlabeled flues - an abandoned coal-furnace flue, an active gas-appliance flue, and a fireplace flue all sharing one crown. You see the photos. We explain what each flue does and what condition it’s in. Then you decide what to clean or repair. Call (781) 404-3793 to schedule - estimates are free.
No. We never recommend relining or rebuilding without camera evidence from inside the flue. In Belmont, we’ve seen companies quote full relines based on exterior staining or age alone, when the real problem was a mislabeled flue, a shared connection from an old conversion, or a missing chimney cap. We put the camera down, show you the photos, and explain what we see in plain English. If the liner is sound, we say so. If it’s deteriorated, we show you exactly where and why. Call (781) 404-3793 for an inspection with photos you can see.
It matters significantly. Belmont’s Colonial Revival and Victorian-era chimneys were sized for the hot, buoyant exhaust of coal and oil appliances. Modern gas appliances produce cooler, wetter exhaust that doesn’t rise as readily in those oversized flues. The result is condensation, corrosion, and draft problems. Many conversions were done without proper liners or with shared flue connections that violate current code. We camera-inspect to assess whether your existing flue is adequate, needs a liner, or has unsafe conditions from the conversion. Call (781) 404-3793 to check your system.
Wind pressure at the chimney top is the most common cause, especially on Belmont Hill where taller stacks catch stronger prevailing winds. A missing or improper chimney cap, a flue termination too low relative to the roof peak, or nearby trees or structures creating turbulent air can all cause downdraft. The problem is often misdiagnosed as a fireplace or damper issue, leading to unnecessary repairs. We inspect the cap, the flue termination, and the surrounding wind exposure to find the actual cause. Call (781) 404-3793 and we’ll sort it out.
First-degree creosote brushes out cleanly, and if your Level 1 or 2 inspection shows no other issues, yes - we sweep it and you’re set for the season. But in Belmont’s older chimneys, we always inspect before brushing. That “simple” creosote job might reveal a deteriorating liner, an unlabeled adjacent flue, or a shared connection from an old conversion that changes what’s safe to do. We don’t skip steps. Call (781) 404-3793 to book a sweep that includes proper inspection.
