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 Somerville chimneys for decades. The triple-deckers on Pearl Street, the converted Victorians near Davis Square, the brick rows along Highland Avenue - our technicians know the housing stock because it’s what we see every day. Somerville isn’t a suburb with detached colonials and one flue per roof. It’s one of the densest concentrations of pre-1920 triple-decker housing in the country, and that changes everything about how a chimney sweep works here.
Why Hearthstone Chimney Co. Is Somerville’s Preferred Chimney Cleaning & Sweep Company
Somerville homeowners call us back because we document what we find. Every Chimney Cleaning & Sweep inspection ends with photos you can see and a plain-English verdict - no jargon, no scare tactics, no pushing repairs that aren’t justified by what the camera shows.
We’ve served local communities for over 42 years. That longevity matters in a city where contractors come and go. We’re not a one-truck operator who might not answer next season, and we’re not a price-cutting chain sending out technicians who’ve never seen a shared-flue triple-decker. Our crews are background-checked, uniformed, and trained specifically on the failure modes of New England’s oldest housing stock.
Calls are answered by a live person, 24/7 - not a voicemail, not a callback queue. When you’re smelling smoke or your CO detector won’t quiet down, that matters. Our no-hassle upfront pricing means the number on the estimate is the number on the invoice. And every job is backed by our 90-Day Done Right Promise: in writing, no arguing. If it’s not right, we come back.
Our Chimney Cleaning & Sweep Services in Somerville
Level 1 Inspection
A Level 1 inspection is the baseline annual service for Somerville homeowners with a heating appliance or fireplace in regular use. We examine readily accessible portions of the chimney exterior, interior, and connecting appliances - checking for obstructions, creosote buildup, and basic structural soundness. In Somerville’s triple-deckers, this means confirming which flue serves your unit before we start, because the wrong flue means the wrong report. A Level 1 sweep and inspection in Somerville typically runs $189-$289.
Level 2 Inspection
This is where we spend most of our time in Somerville. A Level 2 inspection includes everything in Level 1 plus a full camera scan of the flue interior - the standard for real estate transactions, post-storm damage, or any change to your heating system. For Somerville’s 100+ year old brick chimneys, it’s essential. The camera reveals what a visual check cannot: deteriorating lime mortar, spalling brick, abandoned flues left open during oil-to-gas conversions, and dangerous cross-connections between units. We document everything with timestamped photos and a written verdict. Level 2 inspections in Somerville range from $289-$439 depending on flue count and roof access.
Creosote Removal
Creosote builds up in stages. First-degree is flaky soot - brushable. Second-degree is granular and requires more aggressive cleaning. Third-degree creosote, or “glaze,” is a hardened, tar-like deposit that can fuel a chimney fire and often requires chemical treatment or rotary removal. Somerville’s older flues, especially unlined or damaged clay-tile ones, are more prone to third-degree buildup because uneven surfaces and restricted airflow create condensation zones. We assess the degree before quoting treatment. Standard creosote removal is included in our sweep pricing; heavy third-degree glaze runs $150-$350 additional depending on severity and flue length.
Soot Removal & Annual Sweep
An annual sweep removes soot, creosote, and debris before heating season begins. In Somerville, where many chimneys serve multiple units and shared walls mean a fire in one flue threatens neighbors, this isn’t optional maintenance - it’s basic fire prevention. We recommend scheduling before October, when Somerville’s freeze-thaw cycles begin in earnest and heating systems start running continuously. Our annual sweep includes debris removal, a basic operational check, and a written condition report. $189-$289 for most Somerville properties.

Trusted Brands We Service in Somerville
We work exclusively with professional-grade materials - no builder-grade substitutes. For flue relining and repair in Somerville’s older chimneys, we specify HeatShield cerfractory resurfacing for restoring deteriorated clay flue tiles, Gelco stainless steel liners for gas conversions, and Olympia Chimney components where full liner replacement is warranted. We stock common parts locally, so most Somerville jobs don’t wait on shipping. If your triple-decker needs a cap to keep out the squirrels that plague the Winter Hill area, or a crown repair before the next freeze-thaw cycle, we have what fits.
Common Chimney Cleaning & Sweep Problems We See in Somerville Homes
- Cross-connected flues in condo-converted triple-deckers. We regularly find gas inserts vented into flues already serving another unit’s furnace - a carbon monoxide hazard that only a camera inspection reveals. One homeowner on Medford Street discovered this when their CO detector kept chirping; our tech traced the flue, documented the connection, and capped the abandoned oil flue before any cleaning proceeded.
- Abandoned oil-to-gas conversion flues left unlined and uncapped. During Somerville’s waves of condo conversion, many oil flues were simply disconnected and forgotten inside shared chimneys. The brush passes through, but the camera shows bare brick, open mortar joints, and a direct path for CO into neighboring units.
- Spalling brick and eroded lime mortar from freeze-thaw damage. Somerville’s soft, pre-WWI lime mortar can’t handle the Boston area’s repeated winter cycles around 32°F. The surface flakes, joints recede, and water penetrates deeper each season. Annual inspection catches this before structural rebuild becomes necessary.
- Sweeping the wrong flue in a shared chimney. Without confirming unit ownership first, a tech can clean one stack, tell the paying customer their chimney is fine, and leave a blocked or unlined flue serving the condo next door - a mistake that’s easy to make and expensive to discover later.

Call (857) 597-5950 for an exact quote.

FAQs - Chimney Cleaning & Sweep in Somerville
You probably don’t, and neither does your neighbor. We trace flue ownership with a camera, a smoke pencil, and documentation - not guesswork. In Somerville’s condo-converted triple-deckers, it’s common for none of the three new owners to know which flue serves which unit, or to discover that a previous contractor vented a gas insert into a flue already serving another unit’s furnace. We document what we find with timestamped photos and a written report you can share with your condo association or board. Call (857) 597-5950 to schedule - estimates are free.
Yes - and in Somerville’s older shared chimneys, it’s a frequent cause. The gas company checks the appliance, not the flue. An unlined or deteriorating flue, a blocked cap, or a cross-connection between units can all vent carbon monoxide into living spaces even when the furnace itself is functioning perfectly. We run a Level 2 camera inspection to trace the flue from appliance to cap, identify the source, and document it with photos you can see. If we find a problem, we explain exactly what it is and what it costs to fix - no recommendations without evidence. Call (857) 597-5950.
Flaking brick means the freeze-thaw cycle is destroying your mortar joints - common in Somerville’s soft, pre-WWI lime mortar. Whether you need a liner depends on what the camera shows inside the flue. Spalling exterior brick and eroded joints can allow gases to leak through the chimney wall even if the flue itself looks intact. We inspect with a camera before recommending anything. Sometimes the fix is crown sealing and mortar repointing with HeatShield. Sometimes a stainless steel liner from Gelco or Olympia Chimney is warranted. We show you the photos and explain both options. Call (857) 597-5950 for a free inspection.
Once per year per active flue, per NFPA 211 - more frequently if you burn wood regularly or have an unlined gas flue. In Somerville’s triple-deckers, the critical difference is that each unit’s flue needs separate attention. A building with three units and three active flues needs three annual inspections, not one. We schedule these together when possible to minimize disruption and offer reduced rates for multiple flues at the same address. The 90-Day Done Right Promise applies to every flue we service. Call (857) 597-5950 to set up annual service.
Yes, though it requires more than a standard brush-out. Third-degree creosote - hardened, glazed tar - is common in Somerville’s older, unlined or uneven flues where restricted airflow causes condensation. We assess the degree with a camera first, then apply chemical treatment or rotary mechanical removal as warranted. The process may require a return visit to complete full extraction. We quote this upfront after inspection, not after we’ve started. Most third-degree removal runs $150-$350 above standard sweep pricing. Call (857) 597-5950 for an estimate.
