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.

Boston’s older housing stock, from Back Bay brownstones to Dorchester triple-deckers, presents chimney conditions you won’t find in newer markets. We’ve swept flues in homes built before the Revolutionary War and others retrofitted six different times since 1950. That range of experience matters because creosote buildup patterns, liner compatibility, and draft problems vary dramatically based on construction era, fuel type, and how the chimney was modified over decades. In Jamaica Plain, we regularly find unlined brick flues from the 1920s still venting modern gas inserts. In South Boston, we see row-house chimneys shared between neighbors with inadequate separation. These aren’t textbook cases. They’re the actual conditions our technicians diagnose and correct.
Our approach is straightforward: we inspect with a camera, show you the photos, explain what we found in plain English, and give you a written verdict before any work proceeds. No surprises on the bill. No pressure to add services you don’t need. The 90-Day Done Right Promise covers every job, in writing, with no arguing. If it’s not right, we come back. That’s the Keystone Standard we’ve operated under since 1984.
We’re not the cheapest sweep in Boston, and we don’t try to be. We’re the company homeowners call when they’ve already been burned by a low bid that missed a cracked flue tile or a deteriorating crown, then handed them a $4,000 surprise six months later. Our customers are typically homeowners who’ve lived in their houses for twenty years or more and intend to stay. They want the job done correctly the first time so they never have to think about it again.
What Our Chimney Cleaning & Sweep Service Includes
Level 1 Inspection
A Level 1 inspection is the standard visual examination required for annual maintenance on chimneys with no known changes in use or condition. We examine readily accessible portions of the chimney exterior, interior, and connecting appliance to verify structural soundness and freedom from obstructions and combustible deposits. For Boston homeowners with consistent heating habits and no recent weather damage, this is typically sufficient and forms the baseline for every sweep we perform. Our technician documents findings with dated photos you receive as part of your service record.

Level 2 Inspection
A Level 2 inspection is required when you’ve changed your heating appliance, experienced a chimney fire, or are preparing to sell your Boston home. This includes everything in a Level 1 plus video scanning of internal surfaces and accessible attics, crawl spaces, and basements. Hearthstone Chimney Co. uses professional camera equipment to capture high-resolution footage of your flue liner, smoke chamber, and firebox, then walks you through the footage frame by frame. You see exactly what we see, and our written verdict separates what’s urgent from what can wait.

Creosote Removal
Creosote is the tar-like byproduct of incomplete wood combustion, and it accumulates in three stages from flaky soot to hardened glaze. Stage 3 glazed creosote is particularly common in Boston because our long heating season and frequent use of damp or improperly seasoned firewood accelerate buildup. We remove creosote using rotary cleaning systems sized to your flue diameter, followed by HEPA vacuum containment so no debris enters your living space. In neighborhoods like Roslindale and West Roxbury where wood-burning fireplaces see heavy winter use, we often recommend mid-season checks between annual sweeps.

Soot Removal
Soot accumulation from oil and gas appliances is finer and more acidic than wood creosote, and it requires different removal techniques to protect stainless steel and aluminum liners. Our technicians match cleaning methods to your fuel type and liner material, using soft-bristled tools on coated surfaces and more aggressive methods only where appropriate. For Boston homes with older oil-fired systems in neighborhoods like Mattapan and Hyde Park, we pay particular attention to connector pipe buildup that can restrict draft and cause soot blowback into the basement.

Annual Sweep
The National Fire Protection Association recommends annual chimney inspection and cleaning as needed, and most Boston insurers require documentation of compliance. Our annual sweep service combines Level 1 inspection with thorough cleaning tailored to your usage patterns and fuel type. We schedule reminder calls in late summer so you’re cleared before the first cold snap, and we maintain service records dating back decades for long-term customers. Many of our Back Bay and Beacon Hill clients have been on the same September schedule since the 1990s.

Fireplace Cleaning
Fireplace cleaning addresses the firebox, smoke shelf, and visible hearth area that a standard flue sweep doesn’t fully detail. We remove ash deposits, bird nests, and debris from the smoke shelf, check firebrick and refractory panel condition, and verify damper operation. For Boston homeowners with decorative gas log sets, we also inspect burner ports and pilot assemblies for proper flame pattern and carbon monoxide risk. In historic homes with original coal-converted fireplaces, we document masonry conditions that may affect safe operation of modern inserts.

Brands We Service for Chimney Cleaning & Sweep
We’ve serviced and maintained thousands of systems using HeatShield refractory repair products, including their patented cerfractory foam resurfacing for deteriorating smoke chambers. In Boston’s older homes with parged smoke chambers that have cracked or thinned over decades, HeatShield restoration allows us to restore proper geometry without a full rebuild. We stock HeatShield materials and complete most resurfacing jobs in a single visit.
Our technicians are equally experienced with Gelco chimney caps and accessories, which we install on Boston homes exposed to harbor winds and driving rain from the east. A properly sized Gelco cap with integrated spark arrestor prevents water infiltration that destroys flue liners and keeps animals from nesting during our milder winters. We’ve also worked extensively with Olympia Chimney products for stainless steel liner installations and with Famco chimney fans to correct draft problems in tightly sealed modern homes. Whether you have one of these brands or any other make, we can inspect, clean, repair, or replace it with professional-grade materials and no builder-grade substitutes.
Signs You Need Chimney Cleaning & Sweep Right Now
- Strong, smoky odors when the fireplace isn’t in use. That acrid smell permeating your Boston living room during humid summer days is creosote off-gassing, and it indicates significant buildup. Beyond the nuisance, this odor signals that combustible deposits are present in quantities that could ignite during the next heating season.
- Visible black buildup on damper or firebox walls. If you can see more than 1/8 inch of soot or creosote accumulation on surfaces you can reach, the hidden portions of your flue are likely worse. We measure actual deposit thickness with specialized probes during inspection, but visible buildup is your cue to schedule before fall demand peaks.
- Smoke entering the room during normal fireplace use. Draft problems have multiple causes, including flue obstruction from nests, creosote narrowing, or negative pressure from modern HVAC systems. In Boston’s tightly sealed renovated homes, we frequently find that exhaust fans and energy recovery ventilators compete with natural chimney draft. A sweep and inspection isolates the actual cause.
- White or green staining on exterior masonry. Efflorescence (white powder) and chlorophyll-based staining indicate moisture penetration through compromised crowns, deteriorated mortar joints, or missing caps. Boston’s freeze-thaw cycles accelerate this damage, and water inside the flue accelerates liner corrosion while providing no path for creosote to dry and flake away naturally.
- It’s been more than 12 months since your last professional service. This is the simplest and most reliable indicator. Even with light use, birds and squirrels nest in idle chimneys, mortar crumbles, and moisture intrudes. The NFPA 211 standard exists because annual inspection catches problems before they become dangerous or expensive.
Our Chimney Cleaning & Sweep Process - Step by Step
- 1
Schedule and confirm. When you call (857) 597-5950, a live person answers, checks availability for your Boston neighborhood, and confirms your appointment with a two-hour arrival window. We send technician profiles including name and photo before arrival, and we call when en route. You’ll never wait all day wondering if someone will show.
- 2
Protect your home. Our technicians arrive in uniform with background-checked identification, lay drop cloths from the entry to the work area, and set up HEPA-filtered vacuum containment before touching your chimney. We’ve swept chimneys in furnished Beacon Hill parlors and construction-zone gut renovations with equal care for the space.
- 3
Inspect with camera documentation. Every sweep includes at minimum a Level 1 inspection; we recommend Level 2 video scanning for first-time customers and any home with known modifications. The camera reveals flue liner cracks, joint separation, glaze buildup patterns, and obstructions that visual inspection misses. You see the footage in real time and receive still photos for your records.
- 4
Clean with matched methods. Based on fuel type, deposit composition, and liner material, we select rotary chains, poly brushes, or manual tools to remove buildup without damaging surfaces. Creosote removal in Boston’s older unlined flues requires different technique than cleaning a modern stainless steel liner. We contain all debris and leave the work area cleaner than we found it.
- 5
Deliver written verdict and upfront pricing. Before any repair recommendation, we show you the evidence and explain what it means in plain English. If additional work is needed, we provide itemized pricing with no hidden fees. You decide what proceeds. Nothing is sold on pressure or scare tactics. The 90-Day Done Right Promise covers whatever we do, in writing, with no arguing.
How Much Does Chimney Cleaning & Sweep Cost in Boston?
A standard Level 1 chimney sweep with inspection in Boston typically runs $189 to $249 for a single-flue system with routine buildup and straightforward access. Level 2 video inspection adds $80 to $120 depending on flue height and number of appliance connections. Homes with multiple flues, such as the duplex and triple-decker configurations common in Dorchester and Roxbury, are priced per flue with volume discounts applied.
Several factors move pricing within these ranges. Creosote in Stage 3 glazed condition requires more labor and specialized solvents to remove safely, adding $60 to $150. Fireplaces with damaged refractory panels or deteriorated smoke chambers need repair before safe operation, and we quote that separately with photos documenting why. Exterior work such as crown repair or cap replacement is priced based on accessibility, roof pitch, and materials selected from our professional-grade inventory.
The most expensive chimney service is the one that misses a problem. We’ve been called to Boston homes where a $99 sweep failed to identify a cracked flue tile or missing mortar joint, resulting in carbon monoxide infiltration or a chimney fire two seasons later. Our camera inspection catches what visual sweeps miss, and our written documentation gives you something to show your insurer or home inspector. We also offer a permanent 5% Senior and Veteran discount, $50 off any repair over $250, and free second opinions on any written estimate you’ve received elsewhere.
Every estimate we provide is free and carries no obligation. The number we quote is the number on the invoice. Call (857) 597-5950 for exact pricing for your specific Boston home.
