We’ve been answering calls from Chelsea homeowners since well before the oil-to-gas conversion wave of the 1990s and 2000s. Our trucks roll across the Tobin Bridge and up Broadway through the Admirals Hill, Box District, and Chelsea Square neighborhoods every week. We know the triple-decker chimneys here, the shared masonry stacks with two or three flues, the salt-etched mortar that looks fine from the sidewalk and crumbles under a sweep brush. When you call (844) 803-1545, a live person answers, 24 hours a day. We’ll give you a real arrival window, and we’ll be there when we say.
Why Hearthstone Chimney Co. Is Chelsea’s Preferred Chimney Cleaning & Sweep Company
Our reputation in Chelsea was built one triple-decker at a time. Word spread from landlords on Shurtleff Street to homeowners near the Mary O’Malley Waterfront Park because we document what we find, explain it in plain English, and put our 90-Day Done Right Promise in writing with no arguing.
Response time matters in a city where one degraded chimney stack can affect three families. Our technicians are typically in Chelsea within 24-48 hours of your call, often same-day for urgent situations flagged by gas inspectors or plumbers during permit work. Background-checked and uniformed, they arrive with DuraFlex liners, HeatShield refractory mortar, and Famco caps on the truck, not on order.
We understand the local urgency. Chelsea’s housing stock, rebuilt rapidly after the 1908 fire, carries chimneys now 90-115 years old. Many were never properly cleaned after oil-to-gas conversions, leaving oil-soaked clay flue tiles that gas inspectors routinely flag. When that happens, you need a sweep who knows how to coordinate access with multiple tenants and get every flue inspected without creating a scheduling nightmare. That’s the work we do in Chelsea, week after week.
Our Chimney Cleaning & Sweep Services in Chelsea
Level 1 Inspection
A Level 1 inspection is the annual baseline for any Chelsea chimney, required by NFPA 211 for continued safe use. We examine the readily accessible portions of your chimney structure, flue, and appliance connection, looking for creosote buildup, obstructions, and basic structural integrity. For the typical Chelsea triple-decker with a shared masonry stack, this means checking the flue serving your unit while being aware of how neighboring flues may affect draft and ventilation. The inspection includes a written condition report, and if we find anything beyond normal soot, we’ll show you photos and explain exactly what you’re looking at. Most Level 1 inspections in Chelsea run $189-$245.

Level 2 Inspection
A Level 2 inspection goes deeper, with an internal camera scan of the flue from top to bottom. In Chelsea, this is the inspection we recommend for every property that has changed fuel type, changed appliance, or sold in the past decade, which covers a large share of the housing stock here. Our camera reveals what the eye cannot: cracked clay tiles, open mortar joints, gaps between flue sections, and the oil-soaked residue that accumulated for decades before a gas conversion. You receive dated photos, a plain-English verdict, and a written recommendation with upfront pricing for any needed repair. Level 2 inspections in Chelsea range from $299-$425, depending on flue count and roof access.

Creosote Removal
Creosote is the tar-like byproduct of incomplete combustion, and it accumulates in every wood-burning flue. In Chelsea’s older masonry chimneys, especially those with degraded or unlined flues, creosote can build to dangerous levels without the homeowner knowing. Stage 3 glazed creosote, hard and shiny as obsidian, cannot be removed with standard brushes; we apply professional-grade creosote modifiers and mechanical removal tools to break it down safely. For Chelsea’s multi-family buildings, we coordinate with all affected tenants to ensure every flue in the stack is properly addressed. Creosote removal as a standalone service in Chelsea typically runs $225-$340; combined with a Level 1 inspection, the package is $289-$375.

Soot Removal & Fireplace Cleaning
Soot removal addresses the fine carbon residue that coats fireboxes, smoke chambers, and damper assemblies. In Chelsea, we see heavy soot accumulation in fireplaces that haven’t been used in years, often because the previous owner converted to gas and never properly cleaned the firebox. Our service includes vacuuming the firebox, brushing the smoke chamber, cleaning the damper and throat, and inspecting the firebrick for deterioration. For properties near Chelsea Creek where salt air has accelerated metal fatigue, we pay particular attention to damper corrosion and fire grate integrity. Fireplace cleaning in Chelsea runs $175-$265 for a standard firebox; larger or heavily soiled units may reach $295.

Trusted Brands We Service in Chelsea
We stock professional-grade materials from DuraFlex, HeatShield, and Famco on every Chelsea-bound truck, which means most jobs finish in one visit without waiting on parts. DuraFlex stainless liners handle the relines that Chelsea’s converted oil flues so often need. HeatShield refractory mortar seals cracked clay tiles and open mortar joints from the inside, preserving the original chimney structure when full rebuilding isn’t necessary. Famco caps and dampers protect the stack top from the salt-laden rain and snow that Chelsea’s coastal position delivers in abundance. We don’t substitute builder-grade materials to save a few dollars. The job is done right, and we stand behind it.
Common Chimney Cleaning & Sweep Problems We See in Chelsea Homes
- Degraded shared masonry stacks in triple-deckers. Most Chelsea chimneys serve two or three units through separate flues, but the outer brick is exposed to salt air off Chelsea Creek year-round. Mortar joints erode faster than inland neighbors like Malden or Everett, and water infiltration during freeze-thaw cycles opens hidden paths between flues.
- Oil-soaked clay flue tiles never cleaned after gas conversion. Between the 1990s and 2010s, thousands of Chelsea properties switched from oil to gas heat. The clay flue tiles, coated with acidic oil residue, were rarely swept or relined. Gas inspectors across the 02150 zip code flag these regularly during appliance permits, creating urgent sweep-and-reline calls.
- Unlined or partially lined flues in pre-1930 construction. The rapid rebuild after the 1908 fire prioritized speed over chimney detailing. Many original flues lack proper liners entirely, or carry clay tiles now fractured by a century of thermal cycling. A standard sweep brush can catch and worsen these cracks without proper camera guidance.
- Salt-accelerated metal component failure. Chimney caps, dampers, and cleanout doors within a half-mile of Boston Harbor corrode faster than manufacturer specifications assume. We replace these with marine-grade stainless or copper options from Copperfield and Olympia Chimney that withstand Chelsea’s coastal exposure.

Yes, our phones are staffed by a live person 24 hours a day, 7 days a week, including holidays. True chimney emergencies, suspected carbon monoxide blockage, flue fire damage, or inspector-ordered shutdowns, receive priority dispatch to Chelsea. After-hours emergency sweeps carry a $95 expedite fee, but the inspection and any immediate safety work proceed with the same upfront pricing and 90-Day Done Right Promise as standard appointments.
Chelsea pricing is comparable to Everett and Revere, though multi-family buildings with shared stacks sometimes require additional coordination time that nudges the total toward the higher end of our ranges. The unique local factor is the frequency of post-oil-conversion relining needs, which adds $800-$2,400 to a standard sweep if clay tiles are too degraded for safe gas venting. We always camera-inspect before recommending relining, and we show you the photos so you understand why.
