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.

AfterGelco Chimney Cleaning in Boston, NY | Emberly Chimney Cleaners
We provide independent Gelco chimney cleaning and service across Boston, with one thing that sets our work apart here: we know how Boston’s oil-heated triple-deckers corrode Gelco 316Ti liners at the lower flue bends, and we inspect for it on every visit. We’re not manufacturer-affiliated or authorized, which means our recommendations are based on what the camera shows, not what the factory wants us to sell. Call (980) 580-8641 for a written estimate before any work starts.
Why Boston Residents Choose Us for Gelco Service
Our technicians have worked on hundreds of Gelco chimneys across Boston, from original installations in century-old triple-deckers to modern replacements in converted brownstones. That hands-on time means we know where Gelco liners fail here, which cap profiles hold up to harbor air, and when a damper is worth rebuilding versus replacing. Corrine Halstead runs our crew, and she grew up around old masonry chimneys in Inwood, where attached brownstones meant shared stacks and flues nobody inspected until something went wrong. She studied building trades technology at Bronx Community College, spent years working inspection and cleaning jobs across all five boroughs, and she still walks every customer through the camera footage before any price leaves her mouth. That habit is one reason Boston homeowners trust us with Gelco systems we didn’t even install.
We stock OEM-compatible Gelco components locally, which means most repairs don’t wait on a warehouse shipment. You’ll get a written scope, a written price, and a documented photo record of everything we find. Read more about our Gelco sales & service approach if you want the full picture before you call.
Common Gelco Chimney Cleaning Problems We Solve in Boston
- Pin-hole perforations in Gelco 316Ti liners. Boston’s high rate of home heating oil use means flue gas carries sulfur compounds that condense at the lower elbow of the liner. We regularly find thinning and pin-holes there during Level 2 inspections, which is a fail condition under Massachusetts 527 CMR. The fix is usually a new liner section or full replacement, quoted in writing before we touch anything.
- Frozen Gelco top-mount dampers. Boston logs dozens of freeze-thaw crossings each winter, and dampers mounted on exposed rooftops take the brunt. Pivot pins seize, rubber gaskets crack, and upper-floor tenants call about smoke backing in. We can often rebuild the damper assembly with OEM Gelco parts rather than replace the whole unit.
- Gelco multi-flue caps trapping moisture against old brick. On unlined rubble-masonry stacks in Dorchester and Roxbury, condensation gets held against the masonry under the cap. Mortar erodes faster, and chunks of spalled brick end up sitting on the cap screen. We inspect the cap, the crown, and the flue condition together so you know exactly what’s failing and what can safely wait.
- Corroded burner assemblies on direct-vent Gelco fireplaces. Salt-laden air off Boston Harbor accelerates corrosion on gas fireplace components, especially in Beacon Hill and Back Bay brownstones near the water. Lazy yellow flames and intermittent ignition failures are the tell. We can usually restore the unit with an OEM burner replacement if the firebox itself is sound.
- Oil-soot buildup in multi-flue Gelco systems. Boston triple-deckers often run several flues through one stack, and when isolation is poor, soot from one unit’s oil furnace drifts into a neighbor’s wood-burning flue. We clean with chemistry suited to sulfurous oil-soot, not just wood creosote, and we document the cross-flue leakage on camera.
BeforeAfterGelco Service in Boston: What Local Conditions Mean for Your Equipment
One fact about Boston shapes Gelco maintenance more than anything else: the city’s building code requires a dedicated flue for each heating appliance, but many 19th-century multi-flue installations were retrofitted without proper isolation between flues. We see this constantly in Dorchester, South Boston, Jamaica Plain, and Roxbury. During Level 2 inspections on these stacks, our camera frequently reveals cross-flue leakage where oil-soot from one unit’s boiler contaminates a neighboring wood-burning fireplace flue, a direct violation of Massachusetts 527 CMR. For a Gelco 316Ti liner in that environment, the failure accelerates at the lower elbow where hot sulfurous soot concentrates, which is why our Fireplace Services in Boston include annual camera-scan inspections for any Gelco system on a shared stack. This is not a gradual cosmetic issue. It’s a corrosion point that turns a routine cleaning into a liner replacement, and it’s the reason we recommend annual camera-scan inspections for any Gelco system on an oil-heated building in Boston rather than the generic “every year or two” advice you’ll see on manufacturer sites. Different fuel, different chemistry, different inspection interval.
Gelco Models & Products We Service in Boston
We service the Gelco 316Ti Flexible Chimney Liner, the Gelco Direct-Vent Gas Fireplace, the Gelco Top-Mount Damper, and the Gelco Multi-Flue Chimney Cap. For liner, cap, and damper replacements, we recommend OEM Gelco components because they match the original brackets and keep the system’s warranty intact. When a unit is old enough that parts are obsolete or the corrosion is too far gone, we’ll say so plainly and often recommend aftermarket equivalents from DuraFlex or HeatShield when the numbers make sense. We stock common Gelco components locally so Boston turnaround doesn’t stretch into a week longer than it should.
Gelco Service Pricing in Boston
Gelco chimney cleaning in Boston typically runs $185 to $325 for a standard single-flue cleaning, depending on soot class and access. Multi-flue triple-decker jobs run higher because each flue is cleaned and inspected separately. A Level 2 camera inspection is included on every visit, not billed as an add-on. Liner replacement work ranges widely, $1,800 to $4,500 depending on flue height, liner diameter, and whether we’re replacing a section or the full run. What drives the price here is access: Boston roofs are steep, stacks are old, and coordinating around tenants in a triple-decker adds steps. You’ll have a written scope and a written price before anyone starts. Call (980) 580-8641 for a free estimate and we’ll come out and show you what we find.

FAQs - Gelco Chimney Cleaning in Boston
Annually, if the liner serves an oil-fired appliance. Boston’s salt-laden air and sulfur-heavy oil soot work on Gelco 316Ti liners faster than wood creosote ever would, and the lower flue elbow is where the damage concentrates. Annual camera inspection catches pin-holes before they become carbon monoxide problems. Call (980) 580-8641 and we’ll scope yours.
It depends on where the damage is and how far it’s spread. A pinhole at the lower elbow can sometimes be addressed with a sectional repair if the surrounding steel is sound. If the corrosion is widespread or the liner has started to separate at the seams, replacement with a new Gelco 316Ti system is usually the honest call. We’ll show you the camera footage either way, and the price is in writing before you decide.
Because Boston’s freeze-thaw cycles put water into the damper’s pivot assembly, where it freezes, expands, and seizes the mechanism. Cracked rubber gaskets from the same cycles let moisture in. We can usually rebuild the damper with OEM Gelco parts rather than replace it, and we’ll seal the assembly so the next winter cycle is less hostile.
Only after an inspection confirms the flue is compliant with Massachusetts 527 CMR. Many of those fireplaces were sealed in the 1950s through 1970s without relining, and what’s behind the brick is often bare rubble masonry or collapsed clay tile. If you have a Gelco liner already in place, we’ll scope it and tell you plainly whether it’s safe to use or needs replacement before you light anything.
The Boston Chimney Cap & Crown keeps rain and debris out of the flues, which matters. What it can’t do is isolate improperly separated flues inside the stack. That’s a code and construction issue, not a cap issue. Our Level 2 inspections identify cross-flue leakage in triple-deckers regularly, and the fix usually involves relining or isolating the affected flue, not simply changing the cap. Call (980) 580-8641 and we’ll show you on camera what’s actually happening inside your stack.
