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.

Call (781) 277-4630 for a straight answer on your chimney.
Why Trust Top Hat Chimney for Your HeatShield Chimney Cleaning?
HeatShield is a specific material with a specific chemistry. It is not paint. Wendell Pike and his crew have applied, repaired, and correctly maintained HeatShield Cerfractory coatings across Quincy since long before most national outfits even carried the product line. We know how it sets, how it bonds to clay tile versus granite, and what happens when someone skips the surface prep. Wendell picked up the trade at Southwestern College down in Chula Vista, where a good instructor drilled into him that honest work done carefully beats a fast hustle. He has carried that into every Quincy chimney he has climbed since. When we open a HeatShield flue, we know what a proper two-coat Cerfractory application should look like, where it typically fails first, and what the freeze-thaw cycles on Quincy’s triple-deckers do to the joint lines. As an independent HeatShield service provider, we are not bound to push the product. We recommend it when it fits, and we tell you straight when a stainless liner is the better fix.
Common HeatShield Chimney Cleaning Problems We Fix in Quincy
HeatShield is a good product applied correctly. The problem is that a lot of what we see in Quincy was not applied correctly, or it has simply aged out. Here are the real failure modes we find, week after week.
- Opened clay tile joints behind old Cerfractory. Decades of New England freeze-thaw working on Quincy’s clay-tile flues cause the mortar joints between tiles to crack and separate. HeatShield was designed to seal those joints, but when the underlying tile shifts again, the coating can’t hold it together. We regularly find gaps behind Cerfractory that were invisible from the roofline. Last month our tech pulled a HeatShield Cerfractory flue in a 1960s split-level off Quincy Shore Drive where the homeowner bought the house with a “certified” coating from a flip. The clay joints had opened in two places, 8 and 14 feet down. Not visible from the top. We ran our inspection camera, found the gaps, removed the loose material, and reapplied the HeatShield joint repair system plus a fresh Cerfractory coat. The client’s smoke smell was gone that night.
- Peeling or cracked coats from bad surface prep. Cerfractory bonds to a clean, rough surface. If soot or creosote is left behind before application, the coat will peel within a season or two. We see this constantly on DIY jobs and handyman-applied HeatShield work in Quincy’s older capes and ranches. The fix is not always a full redo. Sometimes we can remove the loose sections and patch. Sometimes the whole flue needs a strip and fresh two-coat application.
- Gaps behind the ceramic coating where spalled brick lets hot gases into the chase. This is the dangerous one. When the underlying masonry is spalling, or the mortar between granite blocks has turned to sand, the Cerfractory layer can sit over a void. Hot gases find their way behind it. We spot this with our camera during cleaning. If the flue is structurally compromised, HeatShield is not the answer. We will tell you.
- HeatShield Cerfractory failing at the smoke shelf or damper area. The smoke shelf is a tricky spot. It collects debris, gets coated unevenly, and sits right where the damper frame puts stress on surrounding masonry. Original masonry movement in Quincy’s older triple-deckers often cracks the coating right at this transition point. We inspect the smoke shelf and damper area carefully on every HeatShield job.
- HeatShield installed where it should not have been. Sometimes a previous owner was sold Cerfractory as a standalone fix for an unlined or severely oversized flue. Cerfractory is a thin coating. It seals joints and smooths the surface. It does not create a new structural liner. When we find HeatShield applied to a flue that was never a candidate in the first place, we explain the honest options and let you decide.
HeatShield Parts & Our Repair-vs-Replace Approach
We use genuine HeatShield Cerfractory material and the manufacturer’s foam applicator system for every resurfacing job. No aftermarket substitutes. The chemistry and expansion rate of the material matter for a lasting bond, and we are not going to experiment on your chimney. We stock the standard HeatShield Cerfractory Flue Sealant two-coat system, the Joint Repair System for clay tile liner joints, and the Resurfacing System for full flue relining. We also work with HeatShield CeCure Sleeve Relining when a clay liner has failed at the joints but is otherwise sound. Our repair-versus-replace decision goes like this. If the flue structure is sound and the issue is joint sealing or surface smoothing, HeatShield is a good fix. If the masonry itself is spalling, the flue is offset beyond the Cerfractory spec, or the tiles are collapsed, we will tell you straight that a full stainless liner or a rebuild is the honest answer. We would rather lose a coating job than install one that fails. Call (781) 277-4630 and we will give you a no-hassle price before a single tool comes off the truck.
Our HeatShield Service Process - Step by Step
- 1
Camera inspection, top to bottom. Before any cleaning or coating, we run our inspection camera through the flue. You see what we see. We look for open joints, spalled brick, creosote glaze, and previous HeatShield failures. In Quincy’s older granite-block chimneys, we pay special attention to lime-mortar joints that erode differently than brick.
- 2
Cleaning and surface prep. Glazed creosote must come off before any HeatShield material goes on. Cerfractory will not bond to soot. We clean the flue thoroughly, remove loose material, and rough the surface so the coating has something to grab. This is the step amateurs skip, and it is why their coats peel.
- 3
HeatShield repair or resurfacing. Depending on what the camera showed, we apply the Joint Repair System to open clay tile seams, then follow with the Cerfractory two-coat sealant or foam-applied Resurfacing System. We use the manufacturer’s applicator, not a hand trowel. The foam application is the only way to get even coverage in a flue you cannot reach.
- 4
Post-application camera verification. We run the camera again after the coat cures enough to inspect. You see the finished surface. We point out what changed and what we will watch at the next cleaning. No mystery. The camera footage and a plain-English verdict, every time, no exceptions.
HeatShield Products We Service & Install in Quincy
We work with the full HeatShield line that applies to residential chimneys in Quincy. That includes the standard Cerfractory Flue Sealant two-coat system, the Joint Repair System for clay tile liner joints, the foam-applied Resurfacing System for full flue relining, and the CeCure Sleeve Relining system for clay liner joint failures. Most of what we install in Quincy is the Joint Repair plus Cerfractory combination on older triple-deckers and post-war capes. We also handle our Chimney Cleaning & Sweep services and chimney waterproofing as part of the full HeatShield service, because a good coating does no good if the masonry is still absorbing water from Quincy’s coastal air.
We Also Service These Brands
HeatShield is not the only product we trust. We install and service DuraFlex stainless liners and Gelco chimney caps across Quincy and the South Shore, and we also offer Milton Heatshield service. Some chimneys need a liner, not a coating. DuraFlex is our go-to for full stainless relining when HeatShield is not the right fit. Gelco caps handle the salt-air corrosion we see in Squantum and Wollaston better than most.
FAQs - HeatShield Chimney Cleaning Service in Quincy
No. HeatShield Cerfractory seals joints and creates a smooth, insulated surface inside an existing flue. A new stainless liner is a structural liner that contains the exhaust gases independently of the old masonry. Cerfractory is a good solution for joint failure and minor surface deterioration when the underlying flue is still sound. It is not a structural replacement. If your flue is spalled badly, offset, or unlined, a stainless liner is the honest fix. We will show you the camera footage and you decide.
No. Cerfractory will not bond to a dirty surface. Any creosote, soot, or glaze must be mechanically removed before the coating goes on. This is the number one reason we see DIY HeatShield jobs failing within a season or two in Quincy. The previous owner skipped the prep. We clean to bare flue surface and rough it up before applying. If you have glazed creosote, that comes off first, every time. Call (781) 277-4630 and we will tell you what you are actually starting with.
It depends on what the camera shows. An east wind pushing smoke back into the house is often a draft problem caused by an oversized flue, a cold flue, or a chimney cap that is not doing its job. HeatShield can smooth and slightly narrow the flue, which sometimes improves draft. But if the real issue is a flue that is too large for the fireplace or a cap that is the wrong size, HeatShield alone will not fix it. We diagnose the whole system, not just the coating.
Done correctly, with proper prep and the right two-coat application, HeatShield Cerfractory can last 15 to 20 years in Quincy’s climate, and we provide the same quality Heatshield service in Randolph. The coastal salt air in Squantum, Wollaston, and Marina Bay shortens the life of the surrounding masonry faster than the coating itself. The coating sits on the flue interior. The exterior masonry, the cap, and the flashing are what the salt attacks. We recommend annual cleaning and inspection so we catch joint movement or coating wear before it becomes a smoke leak. Once a year, burn or no burn. Chimneys break in the off-season too.
Sometimes. When a wood-burning fireplace is converted to gas, the flue often needs a properly sized liner for the gas appliance. HeatShield Cerfractory can seal the existing flue and improve performance in some gas conversion situations, but only if the flue size and condition meet code. In many of Quincy’s older homes, the original flue was sized for coal or oil and is far too large for a gas insert. That oversized flue causes condensation and drafting problems that a coating alone will not solve. We will look at the setup and tell you what actually meets code. Call (781) 277-4630 for a straight answer.
A standard chimney cleaning in Quincy typically runs $180 to $320 depending on flue condition, creosote buildup, and whether the chimney is a typical triple-decker flue or a larger granite-block flue in Quincy Center. HeatShield Cerfractory application is a separate line item, usually $1,800 to $3,400 depending on flue height, the number of coats, and how much Joint Repair is needed first. We give you the full price before any work begins. The number you hear on the phone is the number on the invoice. Call (781) 277-4630 for a free estimate.
