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.

AfterHeatShield Chimney Cleaning in Randolph, MA | Top Hat Chimney
We provide our Heatshield services across Randolph, and the one thing that makes our work here different is simple: we know what Randolph’s mid-century chimneys actually do to HeatShield coatings. Most HeatShield liners in this town were installed inside flues originally built for oil burners, and when those homes switched to gas, the oversized flue started working against the liner. Call (781) 277-4630 for a free estimate, and we’ll tell you straight whether your HeatShield needs work or not.
Why Randolph Residents Choose Us for HeatShield Service
We have been inside more Randolph service area chimneys than we can count, and HeatShield liners show up in a lot of them. The product works well when it is sized right and installed right. The trouble in Randolph is that many HeatShield coatings went into flues that were never re-sized after the house left oil behind, and that mismatch causes the coating to fail years early. We know what that failure looks like from the inside, and we know how to fix it without tearing out what does not need replacing.
Wendell Pike started Top Hat Chimney in 1999, and he has been pulling rain caps off Randolph chimneys ever since. He will be the one who shows up, or one of his crew who has been with him long enough to know what he expects. We have not spent two decades driving these streets to start cutting corners now.
Common HeatShield Chimney Cleaning Problems We Solve in Randolph
- Peeling Cerfractory coating from condensation. Randolph homes that converted from oil to gas often kept the original oversized flue. The gas appliance runs cooler, the flue never warms up enough, and condensation sits on the HeatShield surface until the coating starts peeling in sheets. We see this on ranches and split-levels all over town.
- Hairline cracks from freeze-thaw stress. Randolph’s inland Norfolk County position means harder freeze-thaw cycles than Weymouth or Braintree get. Water works into the brick, freezes, expands, and the stress transfers to the HeatShield Cerfractory. Those hairline cracks are not cosmetic. They let flue gases reach the brick.
- Joint separation between flue tiles. The 1950s and 60s homes here settled after construction, and the terracotta tile joints shifted. HeatShield was often applied over those joints without addressing the movement underneath. Now the coating bridges a gap that keeps widening.
- Black streaking on exterior brick. Randolph homeowners sometimes write this off as soot staining from rain. It is not. It is condensation carrying flue residue through the masonry. We have opened cleanouts on mid-century ranches where the liner was sized for a 150,000 BTU oil burner but the house now runs a 60,000 BTU gas appliance. That mismatch creates the condensation, and the streaking tells you it is active.
- Smoke chamber transition gaps. Original terracotta misalignment where the smoke chamber meets the flue is common in Randolph’s older masonry work. HeatShield applied over a misaligned transition looks fine during the install, but the gap underneath keeps moving, and the coating cracks right there.
HeatShield Service in Randolph: What Local Conditions Mean for Your Equipment
Here is the thing most HeatShield pages will not tell you. Randolph homes built in the 1950s and 60s used a specific local terracotta tile size that often lacks the exact dimensional match for HeatShield’s joint repair mesh. That means when we open up a flue on a Cape Cod or raised ranch in this town and find joint separation, we frequently cannot just lay the standard mesh in place. We have to custom-cut it to fit the tile dimensions that were standard here during the post-war building wave. That is not a problem in neighboring towns with newer liner standards, but in Randolph it is routine. It adds a step, but it is the difference between a repair that holds and one that fails again in two years. We learned that the hard way, and we have been doing the custom cutting long enough that it is just part of the job now.
HeatShield Models & Products We Service in Randolph
We service the full HeatShield line: the Cerfractory Flue Sealant, the Joint Repair System, the Resurfacing System, and the CeCure Sleeve Relining System. On the repair side, we use only genuine HeatShield Cerfractory SealTite and CeCure materials, never generic refractory. The coating has to match the original thermal expansion and adhesion properties, and generic material will not do that. We stock the HeatShield products we use most often in Randolph, so most service calls do not wait on a parts order. When repair is localized, we repair. When structural integrity is gone beyond a spot fix, we tell you CeCure relining is the honest answer. And if it does not need cleaning, we will tell you that too.
HeatShield Service Pricing in Randolph
HeatShield repair pricing in Randolph depends on what we find when we get the camera in the flue. A straightforward Chimney Cleaning & Sweep in Randolph runs less than a resurfacing job, and a full CeCure reline is a bigger investment. What drives the cost here is the same thing that drives most chimney work in this town: the age of the original masonry, whether an oil-to-gas conversion left an oversized flue, and how far the deterioration has gone. We give upfront pricing before a single tool comes off the truck, and the number you hear on the phone is the number on the invoice. Call (781) 277-4630 for an exact quote. Estimates are free, and we will show you camera footage before we recommend anything.

FAQs - HeatShield Chimney Cleaning in Randolph
Yes. If the damage is localized, we patch it with genuine HeatShield Cerfractory materials and leave the rest of the liner alone. We only recommend a full CeCure reline when the structural integrity is compromised beyond a spot repair. You will see the camera footage before you decide, so you know exactly what you are paying for.
In most cases, no. We remove loose or peeling material, dry the flue thoroughly, and apply HeatShield resurfacing with SealTite directly over the sound remaining coating. Full removal only happens when the existing coating has failed so completely that it cannot bond.
More than most homeowners realize. If your ranch was built in the 50s or 60s, the flue was sized for an oil burner. When the house switched to gas, the flue became oversized for the smaller appliance. That oversized flue runs cooler, condenses more, and the condensation attacks the HeatShield coating. So your HeatShield problem may have started the day the gas furnace went in. Call (781) 277-4630 and we will inspect the full picture, not just the liner.
We can, but we will not apply it to spalling brick without addressing the water problem first. If water is getting into the masonry and freezing, any new coating will fail the same way the old one did. We handle our Chimney Repair in Randolph as part of the job when it is needed, then apply HeatShield once the flue is dry and stable.
Done right, a HeatShield repair here can last 15 to 20 years. Done wrong, it fails in three. The difference in Randolph comes down to whether the tech addressed the condensation source, whether the tile joint movement was stabilized, and whether the materials matched the original HeatShield spec. That is why we use only genuine SealTite and CeCure and why we custom-cut the joint mesh to fit Randolph’s older tile dimensions. Call (781) 277-4630 for an exact evaluation.
