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.

Malden’s housing stock is unlike most of Middlesex County. The city built fast during the streetcar-suburb boom, and those late-19th and early-20th century wood-frame triple-deckers still dominate neighborhoods like Maplewood, Edgeworth, and the streets around Linden. We’ve been working on these chimneys for over 42 years. We know the original coal-era flue dimensions, the oil retrofit era, and the gas conversions that followed. That history lives in your chimney walls, and it determines whether you need a stainless liner, a partial rebuild, or honest reassurance that your flue is sound for another season.
Why Hearthstone Chimney Co. Is Malden’s Preferred Chimney Liner & Rebuild Company

Our Chimney Liner & Rebuild Services in Malden
Stainless Steel Liner Installation
Malden’s triple-decker chimneys were built for coal, later fitted for oil, and often converted to gas. Those original flues are oversized for modern appliances, which causes condensation to pool and accelerate clay liner deterioration. A stainless steel liner - we typically install DuraFlex for its flexibility in tight, offset flues - sizes the passage correctly for your appliance, eliminates condensation damage, and meets current NFPA standards. In shared stacks around Oak Grove and Linden, we pressure-test adjacent flues before and after installation to confirm no cross-leakage between units. Most stainless liner jobs in Malden run $2,800-$4,200 for a single flue, including the camera inspection and photo report.
Flexible Liner Systems
Some Malden chimneys have offsets or bends that rigid stainless cannot navigate - common in older homes where the flue was modified during a previous conversion. Flexible liners from trusted manufacturers allow us to thread a complete liner through compromised passages without dismantling the stack. We see this need frequently in the narrower two-family homes near Maplewood, where chimney geometry was never standardized. Flexible systems cost roughly the same as rigid stainless in straightforward applications, but complex routing can add $400-$800 to the project.
Liner Replacement
When clay tiles are spalling, cracked, or missing sections, patching is rarely worth the cost. Full liner replacement removes the failed material and installs a new, properly sized system from the smoke chamber to the top of the flue. In Malden, we often find that gas appliances in oversized flues have created unusual creosote patterns - sticky, corrosive deposits that eat clay from the inside out. We document this with camera footage before we quote, so you see exactly why replacement is recommended. A full liner replacement in Malden typically runs $3,200-$5,000 depending on flue height and access.
Partial Chimney Rebuild
The Boston metro freeze-thaw cycle - temperatures crossing 32°F dozens of times each winter - fractures brick faces and opens mortar joints in Malden’s century-old chimneys. When spalling is limited to the upper courses, crown, or a section of the stack, a partial rebuild preserves sound lower masonry while replacing failed components. We rebuild crowns with proper slope and overhang, repoint mortar with matching composition, and install new flashing where the chimney meets the roof. Partial rebuilds in Malden generally fall between $1,800-$3,500, though extensive upper-stack work can reach $4,500. We always photograph the damage and explain what can wait and what cannot.

Trusted Brands We Service in Malden
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, Olympia Chimney, Famco, and Copperfield - brands that hold up in New England’s temperature swings and meet the warranty standards landlords in Malden need for their insurance. Because we stock common liner diameters and crown forms locally, most Malden jobs don’t wait on parts. When a triple-decker owner in Edgeworth calls with a tenant complaint, we can often inspect, document, and repair without a return trip.
Common Chimney Liner & Rebuild Problems We See in Malden Homes
- Shared-stack flue neglect in triple-deckers. Landlords rarely coordinate cleaning across all three tenants, so one flue goes years without service while another is swept. The unswept flue may be blocked, deteriorated, or actively leaking carbon monoxide into neighboring units through open mortar joints.
- Oversized coal-era flues retrofitted to gas. Modern gas appliances exhaust cooler, wetter combustion gases into flues dimensioned for hot coal draft. Condensation accelerates clay liner deterioration and creates creosote deposits even without wood burning - a pattern many Malden homeowners mistake for “just a gas smell.”
- Freeze-thaw damage to crowns and mortar. Water infiltrates deteriorated mortar, expands when it freezes, and fractures brick faces. By late winter, we routinely find spalling and open joints in Malden chimneys that looked sound in October.
- Single-flue cleaning without adjacent-flue inspection. A sweep who cleans only your unit’s flue in a shared stack and doesn’t camera-scope or pressure-test the neighboring flues may leave a blocked or crumbling flue directly beside your live one. Malden fire inspectors have flagged this repeatedly around Oak Grove and Linden.

FAQs - Chimney Liner & Rebuild in Malden
NFPA recommends annual inspection for all chimneys, and in Malden’s triple-deckers we consider that a minimum. Because shared stacks create cross-contamination risk when one flue is neglected, we advise landlords to schedule coordinated Level-2 inspections across all units every 12 months - or at minimum, to have each flue camera-scoped on a rotating schedule with pressure-testing of neighbors. Individual homeowners in two-families should insist on seeing documentation that adjacent flues were checked. Call (781) 404-3793 to schedule; estimates are free.
No. In a triple-decker stack, each flue is a separate passage. Your landlord’s cleaning receipt for Unit 1 means nothing for Unit 2 or Unit 3 unless the technician camera-scoped and pressure-tested all three flues and documented the results. We’ve found blocked, deteriorated flues sitting directly beside recently cleaned ones in Malden buildings around Oak Grove and Linden. Ask to see the photo report for your specific flue, or call us for a free second opinion.
A proper Level-2 inspection includes internal camera examination of the flue, inspection of accessible exterior masonry, crown, flashing, and smoke chamber, plus pressure-testing of adjacent flues in shared stacks. You receive dated photos and a written verdict in plain English. Our flat price for this service in Malden is $249-$349 depending on stack height and access, agreed before we book. No surprises on the bill. Call (781) 404-3793 to confirm pricing for your building.
Yes - and we won’t recommend a liner without camera evidence you can see for yourself. Clay tiles with hairline cracks may need only monitoring. Spalling, missing sections, or glazed creosote that cannot be mechanically removed means the flue is no longer a safe passage for combustion gases. In Malden’s gas-converted, oversized flues, we also measure condensation patterns and draft performance. Sometimes a thorough cleaning and a new cap is sufficient. When a liner is truly needed, we show you exactly why. Call (781) 404-3793 to book an inspection.
We do not promise same-day dispatch. What we do promise: a live person answers your call 24 hours a day, 7 days a week, and we prioritize genuine safety concerns. If your carbon monoxide alarm is sounding, evacuate and call emergency services first. For non-emergency but urgent concerns - strong creosote odor, visible smoke spillage, or a known flue blockage - we schedule the earliest available inspection, typically within 24-72 hours, and we talk you through immediate safety steps while you wait. Call (781) 404-3793 anytime.
Malden’s triple-decker chimneys demand a specific kind of care - one that respects the building’s history, the tenants’ safety, and the landlord’s need for documentation. In the triple-decker blocks off Linden, we opened a first-floor flue that hadn’t been touched in years - third-degree creosote glazed the walls and the flue liner was spalling from years of gas condensation in an oversized clay tile. We camera-scoped the adjacent flues in the same stack and found one with an open mortar joint leaking into the live flue beside it; we rebuilt the crown, installed a DuraFlex stainless liner, and returned a photo report to all three tenants so the landlord could see exactly what was done and what still needed attention. That’s how we work. Photos you can see. A plain-English verdict. Done right - and we stand behind it.
