Why Wichita Falls Homeowners Choose HeatShield Chimney Cleaning
We provide independent HeatShield chimney cleaning and service in Wichita Falls, and what sets our HeatShield work apart is the diagnosis behind it: we inspect the flue with a camera before anyone touches the surface, we document what we find, and we only recommend resurfacing, repair, or a liner when the evidence supports it. HeatShield is a flue resurfacing system, and this page covers how we clean, repair, and service it.
HeatShield systems in Wichita Falls come from a proprietary ceramic refractory mortar family, and owners searching for service on one usually want a technician who knows the difference between a properly applied coating and a failing one. We’re an independent HeatShield service provider. We’re not affiliated with or authorized by HeatShield. Our technicians have up to 15 years of experience with flue systems like this, and we work on HeatShield as part of a broader chimney and ventilation practice.
Wichita Falls sits on the edge of the Texas Rolling Plains, where winter ice storms and hard freezes regularly knock out power for days. That makes chimney work here a storm-season safety question, not an aesthetic one. Call (855) 705-9859. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Why Trust Lionheart Chimney Sweep for Your HeatShield Chimney Cleaning?
HeatShield’s Thermo-Ceramic refractory mortar is a proprietary, engineered system. Independent sweeps who install it must complete HeatShield’s own applicator training to buy and mix the material. That means real expertise in this product shows up in the applicator training and the mixing discipline, not in a manufacturer-authorized badge we don’t claim.
We work with these systems as an independent provider. We document flue conditions before and after relining, so you can see the joint-by-joint difference rather than take our word for it. That documentation matters most in older Wichita Falls housing, where chimneys that date from the mid-20th century oil and Air Force boom years have had decades of patchwork. Original fireboxes and clay flue tiles crack, get patched, and get re-lined. Each layer of history changes what a new HeatShield application will bond to.
The other half of HeatShield expertise is the parts. HeatShield systems are proprietary, so the mortar and coating have to come from HeatShield-authorized distributors. There is no legitimate aftermarket substitute. A sweep mixing a generic refractory mortar is not applying the same product, even if the color matches. We buy through professional chimney trade suppliers, including Olympia Chimney and Copperfield, and we use components that fit the system correctly. That keeps your service warranty-safe and your flue sound.

Common HeatShield Chimney Cleaning Problems We Fix in Wichita Falls
HeatShield resurfacing fails in predictable ways. The failure modes below are what we look for during a Level 2 inspection in Wichita Falls, and each one has a root cause you can trace.
- Delamination and flaking from thin mixing or poor prep. Thermo-Ceramic linings mixed too thin, or applied over a dirty, oily flue with inadequate surface prep, delaminate and flake within a few seasons. The material needs to bond to clean masonry. Creosote-glazed tile gives it nothing to grab. Grey flakes on the hearth or a sandy texture in the smoke chamber usually trace back to this.
- Cracks reopening behind coatings bridged over bad joints. When a coating is applied over badly spalled or offset flue tile joints, the coating bridges the gap instead of filling it. Movement in the tile reopens the crack behind the new surface. The HeatShield looks intact from the top until the inspection camera finds the gap underneath.
- Missing or undersized bond breaks. A liner run continuous past the smoke chamber, without a proper bond break, cracks under thermal expansion. Bond breaks give the resurfaced section room to move. Skip them, and the liner cracks at the point where the flue changes shape or direction.
- Crowns and flue tops left without a proper cap. A crown or flue top resurfaced with HeatShield materials but left uncapped takes Wichita Falls wind-driven rain and hail directly. The new surface pits, the crown coating fails early, and water finds its way back into the flue.
- Freeze-thaw damage on brick and mortar. Plains winters alternate hard freezes with thaws, and water sitting in a cracked crown or an uncapped flue expands and splits the masonry. That damage then undermines whatever resurfacing sits above it.
A blocked or cracked flue doesn’t warn you before it becomes dangerous. If a HeatShield application is failing, the flue behind it may be exposing you to creosote buildup or carbon monoxide. The fix starts with a camera inspection, not a guess.
How a Typical HeatShield Relining Problem Shows Up
A homeowner burning wood in a 1950s brick fireplace notices grey flakes dropping onto the hearth and a rough, sandy texture inside the smoke chamber. A Level 2 camera inspection typically shows an earlier Thermo-Ceramic application that has delaminated where it was applied over creosote-glazed tile. The usual fix is to strip the loose material, clean the flue back to bare masonry, fill and rebuild the spalled joints, and re-apply the HeatShield refractory mortar with proper bond breaks before the crown and cap are addressed. The whole sequence matters. Skipping the strip-and-clean step is exactly how the first application failed.
HeatShield Parts & Our Repair-vs-Replace Approach
HeatShield systems are proprietary. The mortar and coating come from HeatShield-authorized distributors, which means we don’t stock an OEM or genuine HeatShield parts inventory and we don’t claim to. What we do is source correctly, mix to specification, and use quality components that fit HeatShield equipment. Famco and Gelco ventilation components finish the system at the top and bottom of the flue.
Repair versus replace depends on flue integrity, and we won’t push past what the inspection shows. A sound but pitted flue tile is a good candidate for resurfacing with HeatShield. A cracked, offset, or heavily deteriorated flue needs tiles replaced or a stainless liner installed instead. We install DuraFlex flexible liner systems for those cases. If your flue can safely wait another season, we’ll tell you that and put it in the report. Nothing is recommended without camera evidence you can see for yourself.

Our HeatShield Service Process – Step by Step
- 1
Diagnosis. We start with a Level 2 inspection and camera the full flue. We check for delamination, bond-break placement, joint offsets, and crown condition. You see the photos before we plan anything.
- 2
Repair or install. If the flue qualifies, we strip loose material, clean back to bare masonry, fill and rebuild spalled joints, and apply HeatShield refractory mortar with correct bond breaks. If it doesn’t qualify, we explain why and lay out the alternatives: tile replacement or a DuraFlex stainless liner.
- 3
Test. We camera the finished flue and compare before-and-after. We verify the crown, cap, and smoke chamber. You get the documentation, not just our word.
- 4
Warranty-safe closeout. We confirm the installation meets HeatShield’s requirements so your product coverage stays intact, and we go over the maintenance expectations for the system you now have.
One call covers your chimney and your dryer vent. Dryer vent cleaning is one of the leading causes of home fires, and most chimney-only companies won’t touch it. We will.

AfterHeatShield Products We Service & Install in Wichita Falls
We service and install the HeatShield systems that show up in Wichita Falls flues. HeatShield CerfCrete is a ceramic and refractory-based resurfacing mortar for deteriorated flue interiors. HeatShield Thermo-Ceramic is the refractory mortar relining system used to rebuild a failing clay tile flue from the inside. HeatShield chimney crown coating and crown repair materials restore the top of the chimney where water gets in. Each of those is a repair product applied to a specific problem, and each requires the flue to be in the right condition before it goes on. We inspect first, then recommend. If your system needs the crowned-and-capped finish these materials expect, we handle that in the same visit.
We Also Service These Brands
HeatShield is one system in a wider toolkit. We install DuraFlex stainless flexible liners when a flue is past resurfacing, and we use Gelco components at the top and bottom of the vent. We buy through Olympia Chimney and Copperfield because those are the distributors certified chimney professionals rely on. That range means we can recommend the right fix for your flue, not just the one brand we happen to carry. One company, and a real diagnosis behind every recommendation.
FAQs – HeatShield Chimney Cleaning Service in Wichita Falls
You usually can’t tell from the firebox alone, which is why a camera inspection matters. HeatShield Thermo-Ceramic has a distinctive surface texture and a joint-by-joint application pattern, and a generic refractory mortar typically looks smoother and lacks the proper bond break at the smoke chamber. Grey flakes or a sandy residue on the hearth are a sign something is failing regardless of brand. We camera the flue and show you what’s actually there.
No. A HeatShield resurfacing restores the flue surface, but it doesn’t replace the need for annual sweeping and inspection. Creosote still builds up, and a smooth flue surface makes it easier to remove, not unnecessary. Annual sweeping also catches new damage before it spreads. A blocked or cracked flue doesn’t warn you first. Call (855) 705-9859 to book your sweep.
It depends on how far the cracking goes. A hairline crack or surface spalling on a refractory panel can often be repaired with the right material. Cracking that runs through the panel or into the masonry behind it usually means a rebuild is the safer answer. We inspect and show you the extent before recommending anything. Estimates are free.
Early flaking almost always traces to prep or mixing. A Thermo-Ceramic liner applied over creosote-glazed tile, mixed too thin, or run without a proper bond break will delaminate within a few seasons. Wichita Falls winters add stress: hard freezes and thaws move the masonry, and an uncapped flue takes rain and hail directly. The fix is to strip the loose material, clean to bare masonry, and reapply correctly. Call (855) 705-9859 for a free estimate.
Yes. A resurfaced flue is only as good as what sits above it. Without a proper crown and cap, Wichita Falls wind-driven rain and hail pit the new surface and water re-enters the flue. We address the crown and cap as part of the job rather than leaving them for later. That step is the one most homeowners never hear about, and it’s the one that determines whether your resurfacing lasts.
Cleaning a HeatShield-resurfaced flue is a sweep with extra care around the surface, so it’s priced per job by a written estimate after we see the flue. Resurfacing and repair are quoted separately once the inspection shows what’s needed. Estimates are free, and the written estimate sets the final price. Call (855) 705-9859 for an exact quote – estimates are free.
