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.

Medford’s housing stock tells its own story. Walk the side streets off Mystic Valley Parkway or through the Hillside neighborhood and you’ll see it: brick triple-deckers built between 1880 and 1930, their chimney stacks rising three stories with two or three separate flues tucked inside a single masonry column. These chimneys were engineered for coal, later pressed into service for oil, and now vent modern gas appliances through passages far too large for clean, efficient draft. The lime-based mortar is past its century mark. The flue liners, where they exist at all, are often original terra-cotta, cracked by decades of freeze-thaw cycling from the Mystic River valley’s damp cold. We’ve been working chimneys like these for over 42 years. We know what to look for, and we document everything with photos you can see and a plain-English verdict you can understand.

Why Medford Homeowners Choose Hearthstone Chimney Co.
We’ve earned our reputation in Medford the old way: showing up when we say, finishing in one visit, and standing behind the work. Our technicians are background-checked, uniformed, and trained to treat your home like their own. Most jobs are completed same-day, with no-hassle upfront pricing - the number on the estimate is the number on the invoice.
The 90-Day Done Right Promise governs every sweep, inspection, and repair we perform in Medford. If it’s not right, we come back. In writing, no arguing, no paperwork to chase down. This is the Keystone Standard: Krafted right, Every time, Your home first, Standing behind it. It’s not a slogan. It’s how Russell Haines built this company starting in 1984, and it’s how we still operate.
Homeowners in West Medford and South Medford call us back because we explain what we find without dramatizing it. A cracked crown needs addressing before water destroys the brick below. A missing cap is an invitation for squirrels and driving rain. An open, decommissioned flue in a triple-decker is drawing cold air into your neighbor’s living space. We’ll show you the camera footage, tell you what it means, and give you a straight recommendation on what needs doing now versus what can wait.
Our phones are answered by a live person 24 hours a day, 7 days a week. Not an app. Not a callback promise. A human being who can book your appointment, answer your question, or flag a technician if something sounds urgent.
Chimney Cleaning Services We Offer in Medford
Chimney Cleaning & Sweep
We remove creosote buildup, obstructions, and debris from wood-burning, gas, and oil flues using professional-grade brushes and vacuum systems. Every sweep includes a basic structural inspection of accessible components. Learn more about our Chimney Cleaning & Sweep in Medford.

From tuckpointing eroded mortar joints to rebuilding severely deteriorated stacks, we restore structural integrity using materials matched to your chimney’s original construction. We photograph every stage and explain the scope before any work begins. Learn more about our Chimney Repair in Medford.

Fireplace Services
Firebox refractory panel replacement, damper repair and installation, smoke chamber parging, and fireplace door fitting - we handle the full range of fireplace maintenance and restoration for Medford’s older homes. Learn more about our Fireplace Services in Medford.

Chimney Cap & Crown Installation
A proper crown sheds water away from the brick below; a proper cap keeps animals and precipitation out of the flue. We fabricate and install crowns and caps using Gelco and Copperfield components, with sizing precise to your chimney’s dimensions. No more water stains on the firebox ceiling. No more squirrel nests in the flue.

Chimney Liner & Rebuild
When terra-cotta liners have failed or flue passages are oversized for modern appliances, we install stainless steel DuraFlex liners or apply HeatShield cerfractory resurfacing, depending on the condition and configuration. For chimneys beyond repair, we perform partial or complete rebuilds with matching brick and proper engineering for today’s venting requirements.

Neighborhoods We Serve in Medford
Our crews run regular routes through Medford’s most distinctive neighborhoods, each with its own chimney character:
- West Medford - Grand Victorian single-families and converted two-families with elaborate original masonry, often with multiple fireplaces long since deactivated
- Hillside - Dense triple-decker blocks where shared chimney stacks demand careful flue-by-flue inspection and tenant coordination
- South Medford - Mix of pre-war singles and post-war splits, many with exterior chimneys exposed to full weather off the Mystic River
- Medford Hillside / Lawrence Estates area - Larger homes with multiple flues and complex venting histories from successive heating system conversions
Wherever you are in Medford, we aim to book within a few days during peak season, sooner when possible.
Why Medford’s Climate & Housing Affect Chimney Cleaning
Medford sits low in the Mystic River valley, and that geography matters more than most homeowners realize. The river puts moisture into the air year-round, but especially through the shoulder seasons when warm days give way to freezing nights. That moisture wicks into porous brick and lime mortar, then expands as it freezes. By March, the exposed upper courses of a Medford chimney can show significant spalling - faces of brick popping off, mortar joints crumbling to powder. We’ve inspected chimneys that looked sound from the sidewalk and revealed major crown deterioration and internal water damage once we got the camera up.
The housing stock compounds the problem. Medford’s triple-deckers, built fast and cheap between 1880 and 1930, used rubble-stone or brick-lined stacks with lime mortar that was never meant to last 140 years. These chimneys were designed for coal, converted to oil in the mid-20th century, and often converted again to gas - each time leaving flue passages oversized for the new fuel, producing acidic condensate that eats mortar from the inside. In Hillside and West Medford, we regularly find that when a unit converted from oil to gas, the old flue was simply abandoned, the terra-cotta liner left open at the top. That open flue draws cold air, moisture, and sometimes animals directly into the shared masonry, and can pull combustion byproducts from neighboring active flues into living spaces. It’s a configuration we see almost nowhere else in the Boston metro, and it demands a sweep who understands multi-family venting before the brush ever touches soot.
This is why a basic sweep isn’t always enough in Medford. We audit flue ownership, verify venting assignments, and document what we find - because in a triple-decker, what happens in Unit 1’s flue affects Unit 3’s air quality.

FAQs About Chimney Cleaning in Medford
A standard chimney sweep with Level-1 inspection in Medford typically costs between $180 and $260, depending on flue count and accessibility. Triple-deckers with multiple flues may fall at the higher end. Call (857) 392-4709 for an exact quote - estimates are free.
The National Fire Protection Association recommends annual inspection for all chimneys, with sweeping as needed based on use and fuel type. In Medford’s older housing stock, we often find that annual inspection reveals maintenance needs before they become safety hazards - especially given the freeze-thaw moisture damage common to river-valley chimneys. Call (857) 392-4709 to schedule.
Terra-cotta liners can be cleaned if they’re intact, but they cannot be repaired once cracked or spalled. We use camera inspection to show you the exact condition before recommending replacement. If a DuraFlex or HeatShield solution is appropriate, we’ll explain why and show you the footage. Nothing is recommended without evidence you can see. Call (857) 392-4709 for a Level-2 inspection.
Skipped maintenance leads to creosote accumulation, which can ignite at temperatures above 450 degrees and cause a chimney fire. In Medford’s older, often oversized flues, incomplete combustion and poor draft compound the risk. Moisture intrusion from deteriorated crowns or open flues accelerates hidden damage. The cost of prevention is always lower than the cost of rebuilding. Call (857) 392-4709 to book before burning season.
Medford’s triple-decker chimneys contain multiple flues serving separate units, often with complicated ownership and maintenance histories. Abandoned flues left open after fuel conversions draw moisture and cold air into shared masonry, damaging active flues and potentially affecting indoor air quality. We audit flue assignments and document conditions for each unit before cleaning. This coordination step is essential and rarely needed in single-family homes. Call (857) 392-4709 - we’ll walk you through what’s involved for your building.

What Medford Customers Say
"Swept it, capped it, and fitted a proper damper. The downdraft smell we had lived with every summer is gone."
- Allison Doyle"The cap keeps the birds out now, which after two springs of scratching noises above the bedroom is worth every penny."
- Nisha Gupta"Creosote buildup was worse than I realized. He measured it, put a camera up to show me the glazing on the flue, and was honest that we were closer to a chimney fire than I wanted to hear."
- Mark Bennett
