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.

Why Boston Residents Choose Us for HeatShield Service
Corrine Halstead started inspecting Boston chimneys with a camera before most companies even carried one. She learned flue measurement and liner assessment at BOCES Rockland in New York, then spent years working the older triple-deckers along Dorchester Avenue before building her crew across Greater Boston. When we open a HeatShield liner on a converted coal-to-gas flue, we know what we’re looking at because we’ve seen hundreds of them. We bring genuine HeatShield materials, not generic substitutes, and we document everything with photos before and after the job. Every quote is written, every scope is written, and every warranty is written, before anyone starts working. If a HeatShield liner is delaminating, we’ll show you the camera footage and tell you plainly whether it’s a patch job or a full reline. No phone-call estimates, no surprises on the invoice.
Common HeatShield Chimney Cleaning Problems We Solve in Boston
- Cerablanket delamination in converted coal-to-gas triple-deckers. Boston’s triple-deckers were built for coal, then oil, then gas. Each conversion left the flue oversized for the appliance, and oversized flues create condensation that works behind the HeatShield liner and pulls it away from the clay tile. We see this most often in Dorchester and Roxbury.
- HeatShield joint sealant cracks at roofline offsets in Back Bay and South End brownstones. Those neighborhoods sit on filled tidal land, and decades of differential settlement have left chimney stacks leaning or cracking at the roofline. The HeatShield sealant flexes with the structure until it can’t, and then it splits.
- Salt-spray erosion of the HeatShield resurfacing coat in North End and Charlestown chimneys. Atlantic salt air accelerates mortar and surface erosion faster than identical structures just 30 miles inland. Once the resurfacing coat wears thin, the original brick beneath starts spalling, and a standard sweeping won’t fix it.
- Improper original installation in Dorchester triple-deckers where flue tiles were already offset. HeatShield can’t permanently bridge gaps between misaligned tiles. If the original tiles shifted before the HeatShield went in, the product will fail early, and we’ll tell you that directly.
- Heavy glazed creosote requiring chemical treatment, not just brushing. When three tenants on three floors each assume someone else handled the chimney, nobody handles it. We routinely find Class III creosote in shared Boston flues that hasn’t been touched in years.
Our tech opened a triple-decker flue on Savin Hill Avenue in Dorchester and found the HeatShield Cerablanket had pulled away from the clay tile in a 6-foot run above the second-floor fireplace. The third-floor tenant had stopped using the fireplace because smoke was pushing into their unit, so we removed the delaminated section, reinstalled new Cerablanket, and sealed the offset with HeatShield Joint Repair. That’s the kind of job we do regularly across Boston.
BeforeAfterHeatShield Service in Boston: What Local Conditions Mean for Your Equipment
Boston is the only major US city where a single shared triple-decker flue in Dorchester routinely serves three separate rental fireplaces on three different leases. That means a HeatShield liner failure creates liability for one landlord across three tenant units simultaneously, a condition you won’t find in Cambridge or Brookline. When we perform Chimney Cleaning & Sweep in Boston on a shared flue, we’re not just clearing creosote; we’re checking the HeatShield liner’s condition along the entire run, because a delamination above the second floor affects the first-floor tenant’s fireplace and the third-floor tenant’s air quality at the same time. Most of these stacks were built between the 1880s and 1920s without modern clay-tile liners that meet current Massachusetts 527 CMR fire code, and many have been through multiple fuel conversions that left them badly oversized for today’s appliances. The camera doesn’t guess. Neither do we.
HeatShield Models & Products We Service in Boston
We service all four HeatShield product lines: Cerablanket, the Joint Repair System, Restore, and Eco-Clean. We use genuine HeatShield materials because the ceramic fiber chemistry is matched to the product’s expansion tolerances. When a HeatShield liner shows more than 30% delamination or the underlying flue is offset, we recommend a rebuild or stainless reline rather than patching. We stock the most common HeatShield materials locally for fast Boston turnaround, which means we’re not waiting on a distributor when your flue needs attention. Bring us a competitor’s written quote and we’ll give you a free second opinion.

FAQs - HeatShield Chimney Cleaning in Boston
Not reliably, no. A leaning chimney stack means the flue structure itself is compromised, and HeatShield is a resurfacing product, not a structural repair. We’d need to inspect the stack with a camera, measure the degree of lean, and likely recommend our Chimney Repair in Boston for structural stabilization before any liner work. Call (857) 567-8887 and we’ll give you a written assessment.
Most likely the flue was oversized for the current appliance and condensation has been working behind the liner, or the original clay tiles were offset when the HeatShield was installed. Both are common in Boston triple-deckers built before 1920 and converted from coal to gas. We’ll show you the camera footage so you can see exactly what’s happening. Call (857) 567-8887 for a free inspection.
Yes, and it should be a Level 2 camera inspection. A chimney fire can crack flue tiles behind a HeatShield liner without any visible exterior damage, and in a multi-unit, that hidden crack affects every tenant. We document everything with photos and give you a written report. Call (857) 567-8887 to schedule.
No. HeatShield needs a sound substrate to bond to, and spalling brick means the masonry is already shedding material. The spalled areas need to be rebuilt first, then HeatShield can be applied. We’ll show you exactly what needs to happen and what it costs before any work begins. Call (857) 567-8887.
The ChimneySaver certificate documents that a HeatShield liner was installed, but it’s not a substitute for the Level 2 inspection required under Massachusetts 527 CMR. We provide the camera-scan documentation that actually satisfies code. Call (857) 567-8887 and we’ll explain what your property needs.
