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.

AfterWhy Norwood Homeowners Choose HeatShield Chimney Cleaning
HeatShield chimney cleaning in Norwood is an independent specialty service we provide for homeowners whose flues were resurfaced with HeatShield’s Cerfractory or CeCure systems and now need careful, warranty-safe maintenance. We’re not the manufacturer and we’re not an authorized dealer. What we are is a locally owned crew that has worked on hundreds of HeatShield-lined chimneys across Norwood and Norfolk County, and we know exactly how these systems behave after years of New England freeze-thaw cycles. If you have HeatShield in your flue and you’re not sure whether it’s holding up, call (508) 687-5884 and we’ll put a camera up there and tell you straight.
Wendell Pike has been running Top Hat Chimney since 1999, and most of that work has happened right here in Norwood. He grew up in San Diego, but Palomar College’s vocational program taught him the technical side of the trade, and the chimneys of eastern Massachusetts gave him the rest. Around Norwood Center and the neighborhoods off Washington Street, he’s known for one thing above all: if your flue is fine, he’ll tell you it’s fine and head back to the truck.
Why Trust Top Hat Chimney for Your HeatShield Chimney Cleaning?
HeatShield systems are not something you want a stranger poking at with whatever brush is on the truck. The Cerfractory flue sealant and CeCure sleeve components are engineered as a system, and cleaning them wrong can do more damage than the creosote ever would. Our sweeps know the difference between first-degree creosote that brushes off and third-degree glaze that has fused to the surface of a CeCure sleeve. They know not to run an aggressive rotary whip at full speed over a joint that’s already showing hairline cracking. That kind of judgment comes from years of hands-on work, not a training video.
Wendell and his crew have put more Heatshield repair in Norwood and resurfacing jobs behind them in this town than any national outfit that rotates in and out. We carry genuine HeatShield Cerfractory sealant and CeCure components on the truck for most common repairs, which means when we find a failing joint during a cleaning, we can often address it the same visit rather than scheduling a callback two weeks out. And every job we finish, HeatShield or otherwise, carries our 90-Day Done Right Promise in writing. If it’s not right, one call brings us back. No arguing, no invoice.
Common HeatShield Chimney Cleaning Problems We Fix in Norwood
Here’s what actually goes wrong with HeatShield-lined chimneys in this specific market. Norwood’s housing stock runs heavily to pre-1960 Colonial Revivals, Capes, and the mill-era worker cottages along Washington Street and Nahatan Street. A lot of those chimneys were relined with HeatShield in the 1980s and 1990s, and they’re now reaching the age where the original work starts showing its seams.
- Cracked or spalled flue tiles behind the HeatShield layer. HeatShield is only as good as the masonry it’s bonded to. In Norwood’s Neponset River valley, ground moisture wicks up through chimney bases and accelerates spalling in original clay tile. When the tile behind the HeatShield cracks, creosote seeps into the gap and you get a fire risk you can’t see from the firebox.
- Failed HeatShield joint sealant from thermal cycling. Norwood averages over 40 freeze-thaw events per winter. Each one expands and contracts the joint between HeatShield segments. After 20 or 30 winters, the Cerfractory sealant at those joints can develop microscopic separations, and that’s where acidic flue gas starts eating at the underlying masonry.
- Water intrusion at the crown delaminating the Cerfractory. When a crown crack lets water run down the flue wall, it gets between the HeatShield surface and the brick. Freeze-thaw then pops the Cerfractory loose in sheets. This is why we always check crown condition on any HeatShield service call in Norwood.
- Creosote buildup inside CeCure sleeves in taller chimneys. CeCure sleeves change the flue’s internal diameter, which alters draft characteristics. On taller chimneys like the two-and-a-half-story Capes near Norwood Center, reduced draft can let creosote condense more heavily inside the sleeve. We adjust our cleaning approach for that.
- Smoke backing up from a hidden flue offset crack. Norwood’s older homes often have two or more flue offsets. HeatShield follows those offsets, and a cracked fireclay tile at the bend can trap creosote behind the liner and push smoke back into the room. A standard sweep won’t touch it. A camera scan will find it.
HeatShield Parts & Our Repair-vs-Replace Approach
When we can preserve an existing Heatshield service in Brockton system, we do. The test is simple: is the underlying structure sound, and is the liner less than ten years old? If both answers are yes, we repair joints. We use genuine HeatShield Cerfractory sealant for joint work and CeCure sleeve components when a section needs replacing. For localized spalling or crown damage, we source matching refractory materials and stainless steel top plates that meet or exceed HeatShield specification. What we don’t do is sell a full reline because it’s easier for us to bill.
The camera footage and a plain-English verdict come with every job, no exceptions. If your HeatShield liner has ten good years left in it, Wendell will tell you that. Call (508) 687-5884 for an honest read on what your flue actually needs.
Our HeatShield Service Process - Step by Step
- 1
Diagnosis. We run a Level 2 camera inspection specifically looking for HeatShield failure points: joint separation, surface delamination, or creosote packed behind the liner. You see the footage on the spot.
- 2
Repair or cleaning. If the system is sound, we clean it with tools matched to the HeatShield surface. If we find a failing joint or a cracked section, we quote the repair before any work happens, and the number we quote on the phone is the number on the invoice.
- 3
Testing. After repair or cleaning, we verify draft and check for any remaining blockages. If the repair involved HeatShield Cerfractory, we confirm it’s set properly before we leave.
- 4
The 90-Day Done Right Promise. Everything we do is backed in writing. If the repair or cleaning isn’t holding up, one call brings Wendell and the crew back. No charge, no debate.
HeatShield Products We Service & Install in Norwood
We work on the full Heatshield in Stoughton line you’re likely to find in Norwood homes: the Cerfractory Flue Sealant system for resurfacing existing flues, the Joint Repair System for targeted fixes at seams and offsets, the CeCure Sleeve Relining System for full structural relining, and the Eco/Glo Liner for smaller-diameter applications. We stock common Cerfractory sealant and CeCure components on the truck, which means most repair work can be completed on the first visit rather than waiting on a distributor.
We Also Service These Brands
While HeatShield is a specialty of ours, we’re not a one-brand shop. We install and service stainless steel liner systems from DuraFlex and Gelco as well, and we’ll recommend whichever system actually fits your chimney rather than whichever one we happen to carry. If a different liner makes more sense for your flue, we’ll say so.
FAQs - HeatShield Chimney Cleaning Service in Norwood
Yes, but technique matters. HeatShield’s Cerfractory surface is harder than clay tile and tolerates standard poly or wire brushes fine, but we adjust pressure and speed around joints and offsets where the sealant is more vulnerable. A careless brushing can accelerate joint failure that’s already started. We know exactly how hard to work each section of a HeatShield flue, which is why we recommend professional cleaning rather than a DIY sweep.
The first sign is usually a faint creosote smell that lingers even after a sweep, or smoke that backs into the room on windy days. What happens is this: thermal cycling opens microscopic gaps in the Cerfractory joint, creosote vapor pushes through and condenses behind the liner, and the smell keeps coming back because the source is behind the HeatShield layer, not on top of it. A camera scan will catch it before it becomes a fire. If you’re smelling creosote in a Norwood home with HeatShield, call (508) 687-5884 and we’ll find exactly where it’s coming from.
HeatShield’s warranty language is specific about the crown being structurally sound and correctly flashed. If water has been getting in at the crown and the Cerfractory delaminates as a result, that’s typically considered a crown failure, not a liner failure. We address crown condition on every HeatShield service call because it’s the most common way these systems fail in New England. A cracked crown gets repaired before we touch the liner.
No. HeatShield is designed to bond to masonry and clay tile, not to a stainless steel surface. If you have a steel liner with pinholes from corrosion or a poor original install, the correct fix is a replacement liner, and depending on your setup, HeatShield CeCure is often the right choice after the old liner is removed. We’ll show you the corrosion on camera before any work is quoted, so you know exactly what you’re paying to fix.
Because the creosote isn’t on the surface of the HeatShield where the brush can reach it. It’s packed behind the liner at a cracked tile or a separated joint. The smell persists because the creosote is still there, soaking into surrounding brick. This is one of the most common findings on our first-visit calls in Norwood’s older homes, and it’s exactly why we run a Level 2 camera scan rather than just pushing a brush through and calling it done.
A standard HeatShield cleaning in Norwood runs roughly $180 to $340 depending on flue height and whether we’re also doing a Level 2 camera inspection. If we find joint failure or delamination, repair cost depends entirely on what we see. Estimates are free, and the price we quote before work starts is the price on the invoice. Call (508) 687-5884 for an exact number on your flue.
