Why Columbus Residents Choose Us for HeatShield Service

HeatShield is only as good as the prep underneath it. Our owner Hank Delano learned that the hard way, years before he started Flint Chimney Sweep. He’s been around chimneys his whole working life, through the building maintenance and construction technology program at Los Angeles Trade-Technical College and the hands-on years that followed. When we look at a flue, we’re looking at the surface the HeatShield has to grip. If that surface is loose mortar or spalled terra cotta, no coating in the world will hold.

We’ve done hundreds of HeatShield restorations in Columbus, from older brick chimneys in the established neighborhoods to newer builds. We’re an independent service provider. Not manufacturer-authorized, not tied to a corporate script. That means when HeatShield is the right call, we say so. And when a stainless steel liner makes more sense, we tell you that too, with camera footage to back it up. The HeatShield sales & service work we do here comes with the same 365-Day Done Right Promise every Flint job carries: a written guarantee on the repair, valid for a full year, with a free return visit if it fails.

Common HeatShield Chimney Cleaning Problems We Solve in Columbus

• Cerfractory coating delaminating after a humid summer. Central Ohio summers can be sticky, and if a previous crew applied HeatShield without letting each pass cure properly, the coating lifts. We remove the failing layer, prep the surface, and reapply with correct drying time between coats.
• Cracking at the flue crown joint. Columbus winters bring freeze-thaw cycles that push and pull at the crown-to-flue connection. Water gets in, freezes, expands. We seal the crown joint before any HeatShield goes on.
• Spalling terra cotta underneath the HeatShield layer. In older Columbus brick chimneys, the original terra cotta liner may be flaking in pieces. HeatShield can’t bond to that. We grind out the loose material, tuckpoint the mortar joints, then coat.
• Flaking from heavy creosote buildup. If a chimney sees frequent wood burning in Columbus, creosote deposits can compromise the bond between the HeatShield layer and the flue wall. We clean to bare surface first, every time.
• HeatShield applied without joint repointing. This is the one we fix most often. The coating looks fine on the surface but the mortar joints underneath were already washing out. Once those joints move, the HeatShield cracks. We rebuild the joints before we coat them.

HeatShield Service in Columbus: What Local Conditions Mean for Your Equipment

Columbus has one of the highest concentrations of 1920s through 1940s brick chimneys in the Midwest. That matters because those original liners usually fail at the mortar joints before the terra cotta itself cracks. Over decades, freeze-thaw cycles in central Ohio push water into the joints, where it expands and contracts until the mortar begins to wash out. By the time a homeowner calls us, the flue often looks fine from the outside but the joints inside are coming apart.

That’s why our HeatShield prep in Columbus includes grinding out and repointing those joints first. It’s a step a lot of sweep-and-coat outfits skip, because it’s messy and slow. But it’s the difference between a HeatShield layer that lasts and one that cracks in two winters. We see it all the time in neighborhoods like Clintonville and Old North. If you’re not sure what shape your joints are in, our Columbus Chimney Inspection with Level 2 camera will show you. We don’t coat what we don’t inspect.

HeatShield Models & Products We Service in Columbus

We work with the full HeatShield product range: the standard Cerfractory Flue Sealant, the high-temperature mix for furnaces and boilers, the insulation mix for colder climates like ours, and the Resurfacing System with Armor Coat. For every restoration in Columbus, we use genuine HeatShield Cerfractory materials. Aftermarket substitutes don’t carry the same UL listing or thermal ratings. We stock the standard and high-temperature mixes locally for faster turnaround, and we’ll order specialty formulas as the job requires. If your flue is too far gone for HeatShield, we’ll recommend a stainless steel liner instead, and we’ll show you exactly why with the camera footage. We cover the Columbus service area and we list every material on the written estimate you approve before any work starts.

FAQs – HeatShield Chimney Cleaning in Columbus

How does HeatShield hold up to Columbus winters compared to a stainless steel liner?
HeatShield performs well in Columbus winters when the flue joints have been repointed and the crown is sealed first. A stainless steel liner is the stronger option when the terra cotta is severely spalled or the flue has shifted. We’ll show you the camera footage and recommend based on what we see, not on which product costs more.

Can you apply HeatShield over a chimney that has already been swept and has heavy creosote staining?
No. The flue surface must be clean and sound before HeatShield goes on. We remove the creosote thoroughly and let the surface dry before applying the first coat. Skipping this step is how the coating flakes, and we won’t do it.

What is the difference between HeatShield’s standard mix and the insulation mix for Columbus homes?
The standard mix restores a smooth, durable flue surface. The insulation mix adds a thermal layer that helps reduce condensation and improve draft, which matters in Columbus’ cold winters. We’ll recommend the right one based on your flue size, fuel type, and how the chimney drafts. For an exact recommendation, call (830) 251-4560 and we’ll inspect your chimney before we quote.

My chimney was HeatShielded five years ago and now has a crack – can it be repaired or does it need a full redo?
It depends on the underlying condition. If the crack is in the HeatShield layer only, we can often grind out the damaged area and reapply. If the bond failed because the mortar joints underneath were never repointed, the full section may need to be redone. We’ll camera the flue and show you exactly what’s going on before we recommend any work. Call (830) 251-4560 for a free inspection.

Do you need to remove the fireplace insert to apply HeatShield in a Columbus home?
Usually yes. The insert blocks access to the flue above it, and we can’t properly prep or coat what we can’t reach. There are some cases where an offset chimney allows access, but most inserts come out for the work and go back in once the HeatShield has cured.
