Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
HeatShield Chimney Cleaning in Humble, TX | Flint Chimney Co Houston
We’re Flint Chimney Co Houston, and our Chimney Sweep - Humble team cleans and services HeatShield-coated chimneys across Humble, Texas. A standard chimney sweep here typically runs $169-$289, and if you have a HeatShield liner, expect us to spend extra time checking the coating itself, not just scraping creosote. What makes our HeatShield work different in Humble is that we know exactly how the local clay soil shifts crack those coatings before winter’s first fire. Call (325) 750-6259 for a written quote before any work starts.
We’re an independent HeatShield service provider, not affiliated with or authorized by the manufacturer. That matters because we have no incentive to push a re-coat when a $40 joint seal is the honest fix. Hank Delano, our owner, learned the trade at Los Angeles Trade-Technical College and has been on Houston-area roofs for over a decade. He’ll sketch what he finds on a notepad before quoting a dollar. HeatShield sales & service is a core part of what we do, and we’ve worked on enough Humble systems to tell you straight what holds up and what doesn’t.
Why Humble Residents Choose Us for HeatShield Service
HeatShield is a cementitious resurfacing product applied inside flues to seal cracks in clay tile liners. It’s good material when installed right. The problem in Humble is that the ground underneath many neighborhoods moves more than people realize. That movement puts stress on chimneys, which puts stress on any HeatShield coating inside them.
We’ve serviced HeatShield systems all over this part of Harris County, and we know the failure patterns by heart. Hairline cracks from clay soil shifts. Spalling at the bond line when a cold front follows a damp week. Joint sealant shrinkage in 1970s chimneys. When you book with us, you get a background-checked, uniformed technician who documents everything with a camera before recommending anything. Every repair carries our 365-Day Done Right Promise in writing. If a covered repair fails within a year, we come back at no charge. That’s The Garrison Standard, and it applies to every job we do.
We also answer the phone. A live person, 24 hours a day, seven days a week. No voicemail trees.

Common HeatShield Chimney Cleaning Problems We Solve in Humble
- Hairline cracks in the original Cerfractory coating. Humble’s humid air gets into those fine cracks and condenses inside the flue. That condensation re-liquefies creosote, turning a dry, brushable deposit into a sticky tar that’s much harder to remove and far more flammable. We see this on HeatShield Original coatings more than any other issue.
- Spalling at the HeatShield-to-clay-tile bond line. A warm, damp week followed by a sudden cold front causes thermal shock. The cementitious HeatShield expands and contracts at a different rate than the clay tile beneath it, and the bond starts to let go. Homes in Humble get these temperature swings often enough that spalling is a routine find.
- Corrosion at the top of steel HeatShield collars. Humble gets heavy seasonal rain and wind-driven moisture. If the chimney cap is loose, even by a little, water pools where the steel collar meets the flue. Over time, that rust eats through. We check the cap seal on every HeatShield inspection here.
- Joint sealant shrinkage behind the HeatShield surface. In 1970s chimneys near FM 1960, the original clay tiles shift as the ground moves. The HeatShield surface might look fine from the firebox, but flue gas leaks behind it through shrunk joints. A Level 1 camera catches this before it becomes a smoke or carbon monoxide problem.
- Creosote building up faster than the sweep schedule expects. High humidity in Humble means moisture in the flue condenses more readily. That wet creosote glazes onto the HeatShield surface and the clay behind it. If you only burn occasionally, the problem gets worse. A sweep every year is the floor, not the ceiling, for Humble homes.
HeatShield Service in Humble: What Local Conditions Mean for Your Equipment
Here’s the thing about Humble that most chimney companies won’t explain: the soil here is expansive clay, and it swells and shrinks with moisture. When it rains, the ground pushes up against foundation and chimney bases. When it dries, it pulls away. That movement, season after season, flexes brick chimneys enough to crack clay tile liners. If you live in an older neighborhood off FM 1960, your chimney likely has original clay tiles that have been quietly shifting for decades.
What that means for HeatShield owners is specific. A HeatShield coating applied five years ago, when the tiles were still fairly stable, can develop fine vertical cracks that weren’t there at the last inspection. Not because the product failed. Because the chimney moved. We’ve documented this on Bender Avenue, where our tech removed loose HeatShield, repointed the tile joint beneath, and re-coated with genuine HeatShield Cerfractory. The homeowner had no idea anything was wrong. The firebox looked clean. The camera told a different story.
That’s why we won’t quote HeatShield work in Humble without a Level 1 camera inspection first. Tell me what you’re seeing, I’ll tell you what it costs to fix it. That’s how Hank has always run it.
HeatShield Models & Products We Service in Humble
We work on every HeatShield product line installed in Humble homes:
- HeatShield Original – the cementitious resurfacing for clay flue liners, and the one we see most in 1970s-90s brick homes.
- HeatShield Cerfractory Flue Sealant – used for spot repairs and crack filling during resurfacing jobs.
- HeatShield Joint Repair System – specifically for failed mortar joints between clay tiles, common in shifting Humble soil.
- HeatShield Hybrid System – stainless steel combined with cerfractory, used when the flue needs structural support plus sealing.
For any HeatShield repair, we use genuine HeatShield Cerfractory and joint materials. Mixing third-party refractory products can create a bond failure, and we won’t do that to save a few dollars. But we’re also straight about repair-versus-replace. If the underlying clay tiles are badly shifted, or the HeatShield surface is delaminating over more than a third of the flue, we’ll tell you a stainless steel reline is the better long-term call. We stock DuraFlex stainless liners and genuine HeatShield materials for fast turnaround in Humble.

FAQs – HeatShield Chimney Cleaning in Humble
You usually can’t tell from the firebox alone. The signs we look for are fine vertical cracks in the HeatShield surface, visible only with a Level 1 camera. In Humble’s expansive clay soil, those cracks often run right where the underlying clay tile shifted. If you’ve noticed a damp smell after rain or smoke backing into the room on windy days, call (325) 750-6259 for a camera inspection with your next sweep.
Yes, in many cases. If the bond is sound over most of the flue and the spalled areas are small, we remove the loose material, prep the surface, and re-coat with genuine HeatShield Cerfractory. If delamination covers more than about a third of the flue, we’ll recommend a stainless steel reline instead. We’ll show you the camera footage either way.
It doesn’t make the HeatShield itself produce more creosote, but humidity changes how creosote behaves. Moist air condenses inside the flue, and that wet creosote sticks to the HeatShield surface and turns glazed. It’s harder to brush off and more flammable. That’s why we recommend annual sweeps in Humble, even if you only burn occasionally. Call (325) 750-6259 to schedule before the humid season peaks.
No. HeatShield is a resurfacing product, which means it’s applied over an existing clay tile liner. If your chimney has no liner, or the existing tiles are beyond saving, we’d quote you for a stainless steel reline. That’s the honest answer, and it’s the same one we give every Humble homeowner.
Joint Repair targets the mortar joints between clay tiles. We grind out failed mortar, pack in HeatShield joint sealant, and leave the tile surfaces alone. A full resurfacing coats the entire flue interior with HeatShield Cerfractory. In Humble, where clay tiles shift, we often find that joints need repair even when the tiles themselves look intact. Call (325) 750-6259 and we’ll tell you which one your chimney actually needs after a camera inspection.
