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.

How HeatShield Products Fail - and How We Fix Them
HeatShield built its name on a ceramic refractory mortar that gets troweled or pumped into place to repair fireboxes and flue walls. It’s good material. But we’ve been inside enough Haverhill chimneys to know exactly where it gives out, and most failures follow patterns you can see coming.
- HeatShield FireGuard firebox panels cracking at the mortar joints. The FireGuard system uses refractory panels rated for direct flame contact, but the mortar between those panels takes the worst of the expansion and contraction. In Haverhill homes where fireplaces sit dormant all summer and then get hit with a hot fire in October, those joints crack first. We pull the loose mortar, re-point with HeatShield-compatible refractory mortar, and the repair usually holds for years.
- Cerfractory flue sealant flaking after a chimney fire. If a flue has been repaired with HeatShield’s Cerfractory line and later sustains a chimney fire, the glaze can spall or flake off in sheets. The homeowner sees what looks like sand in the fireplace and thinks the liner is failing. It is. We camera the flue, document the spalled areas, and decide whether a re-coat is enough or the underlying flue tile has shifted and needs a different fix.
- Smoke rollout on HeatShield-repaired smoke chambers. HeatShield’s SmokeGuard material is parged onto the corbeled brick in the smoke chamber to smooth airflow. When applied too thick, or when the original chamber bricks were badly out of alignment, the surface can develop ridges that catch creosote. In Haverhill’s older colonials up near Bradford, we see this on chimneys where the smoke chamber was never sized right for the flue. The fix is usually a re-parge to restore a smooth, continuous surface.
- HeatShield liner installed over water-damaged flue tile. We’ve pulled cameras through more than a few Haverhill chimneys where a previous contractor pumped HeatShield Cerfractory over flue tile that was already spalling from rain exposure. The HeatShield held, but the host tile kept crumbly behind it. The flue looks repaired from the top, but the camera shows the truth. When we find this, we don’t patch it. We tell you what’s actually holding the flue together and whether you need a real structural fix.
- OEM HeatShield patch kits failing when owners DIY the mix ratio. HeatShield sells repair products to contractors, not really to homeowners, but we’ve seen kits bought through gray-market outlets and DIY’d into place. Wrong water ratio, applied too cold, or put over a dirty surface, and the material won’t bond. It cracks within a season. We clean the surface properly, mix to spec, and apply at the right ambient temperature, which matters more than people think in a Haverhill January.
Our HeatShield Fireplace Services Process
Here’s how a HeatShield fireplace job goes from the first phone call to the last sweep of the drop cloth.
- 1
You call, we pick up. Wendell or one of the crew takes your call, asks what you’re seeing, and gives you a straight answer on whether it sounds urgent or can wait a week.
- 2
The sweep shows up on time. Uniformed, background-checked, and ready with a camera. We don’t quote anything until we’ve actually looked.
- 3
We run the camera. Every HeatShield service includes camera inspection of the firebox and flue. You see the footage. We don’t describe a problem and ask you to trust us. We show you.
- 4
We make the call on parts with you. If we’re replacing a HeatShield component, we talk about OEM vs. quality aftermarket parts, lead time, and warranty. If aftermarket is just as good and costs less, we say so.
- 5
We do the work. HeatShield repairs, firebox rebuilds, damper fixes, conversions, whatever was agreed. The price on the invoice matches the price on the phone.
- 6
We test and we guarantee it. Fire it up, check the draft, check the seal, show you the results. Then the 90-Day Done Right Promise goes in writing. If it’s not right, one call brings us back at no additional cost.
What HeatShield Fireplace Services Costs in Haverhill
Cost depends on what’s actually wrong, and we don’t quote until we’ve looked. That said, here’s what Haverhill homeowners can generally expect for common HeatShield work.
- HeatShield firebox crack repair: $250-$650, depending on linear feet of cracking and whether panels need resetting.
- HeatShield Cerfractory flue resurfacing: $1,800-$4,200 for a typical one-story flue, more for two-story Haverhill colonials or flues with heavy spalling.
- Damper repair or replacement for a HeatShield fireplace: $180-$520, part and labor.
- Gas fireplace service on a HeatShield unit: $150-$300 for a cleaning, burner check, and safety test.
- Full firebox rebuild with HeatShield firebrick and refractory mortar: $1,200-$3,500, depending on size and access.
What moves the price: access to the roof, flue height, how much of the old material has to come out, and whether the underlying masonry is sound. The estimate is free. Call (978) 724-7935 and we’ll give you a number before any work starts.
Why Haverhill Homeowners Call Top Hat Chimney for HeatShield Work
We’ve worked the same streets since 1999. Wendell Pike founded this business, runs it, and puts his name and license number on every job we do. No franchise rotated in last spring. No call center. When you call at 2 a.m. because you smell gas from your HeatShield fireplace, Wendell or one of his crew picks up.

We’re an independent HeatShield service provider, not a manufacturer-authorized shop, and that’s a good thing for you. We’ll tell you when a HeatShield repair is the right call and when a DuraFlex or Gelco part would do the job better for less money. Every job ends with the 90-Day Done Right Promise in writing. If it’s not done right, you call and we come back.
Ask anyone on your street. They’ll tell you the same thing: Top Hat Chimney shows up, does the work, and tells you straight. If it doesn’t need doing, we’ll tell you that too.
FAQs
No. As an independent HeatShield service provider, we perform repairs and maintenance that meet or exceed the manufacturer’s installation standards, and we use HeatShield-compatible materials. We document every job with photos and camera footage, so you have a record of what was done and when. That’s the same standard any authorized shop would meet.
Most common HeatShield components are available within 3 to 5 business days from our regional suppliers. If a part is backordered from the manufacturer, we tell you upfront and give you alternatives, including quality aftermarket options that often ship faster and cost less. You’ll know lead time before we order anything.
In most Haverhill homes, a HeatShield firebox repair is worth it if the underlying firebrick and masonry are still sound. Cracks in the refractory panels or mortar joints are almost always repairable for a fraction of what a new fireplace insert costs. We’ll camera the firebox and tell you straight: if the structure is shot, we’ll say replace. If it just needs re-pointing, we’ll say that.
Yes. We service HeatShield gas fireplaces, wood burning fireplaces, and fireplace inserts throughout Haverhill. The service includes burner cleaning, pilot and thermocouple checks, safety testing, and a full firebox inspection. We also handle fireplace conversions if you want to switch fuel types.
Once a year, burn or no burn. Chimneys break in the off-season too, and Haverhill’s freeze-thaw winters are hard on mortar and refractory materials. An annual service catches small cracks before they turn into smoke problems or fire hazards. Call (978) 724-7935 to book your annual HeatShield fireplace inspection.
