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 Houston, TX | Flint Chimney Co Houston
We provide independent Chimney Sweep - Houston and HeatShield repair across Houston. Call (325) 750-6259 for a free estimate. One thing separates our HeatShield work here from a generic sweep: we check for liner damage caused by Houston’s expansive clay soil and humidity, not just creosote buildup. Flint Chimney Co Houston has been servicing HeatShield systems in this city for over a decade, and we stock the products needed for same-trip repairs. If you own a HeatShield-lined chimney, this page tells you what to watch for and what it costs to fix.
Why Houston Residents Choose Us for HeatShield Service
We work on HeatShield systems every week across Houston. Because we’re independent, we can tell you straight when a HeatShield repair is worth the money and when a different fix makes more sense. We’ve watched these liners fail over years in Houston’s humidity and shifting gumbo clay, not just read about it in a manual. Hank Delano, our owner, grew up in Los Angeles and learned the trade at Los Angeles Trade-Technical College before bringing his crew to Texas. He has serviced Houston homes for over a decade, including a steady run of jobs in Montrose where older masonry fireplaces keep us busy. Hank’s known for sketching a quick diagram on a notepad to show a homeowner exactly what the camera found in the flue before quoting a dollar.
Every job gets a written price before any tool comes off the truck. The number you approve is the number on the invoice. And every repair carries our 365-Day Done Right Promise: a written guarantee valid for one full year. If a covered repair fails in that window, we return at no charge. That’s the Garrison Standard, the same code every Garrison Partners location follows. We’ve been part of that family since it started in 2002.

Common HeatShield Chimney Cleaning Problems We Solve in Houston
- Cerfractory sealant cracking from thermal cycling. Houston fireplaces get used sporadically. A cold start after months of disuse puts real stress on the HeatShield Cerfractory Flue Sealant, and we regularly see hairline cracks where the material pulled away from the flue tile. Left alone, those cracks let smoke and heat reach the brick behind the liner.
- Joint repair material washing out after heavy rain. Houston gets biblical downpours. If the crown is cracked or the flashing is loose, water pours down the flue and erodes the HeatShield Joint Repair System over time. We find this a lot on homes where gutters were never quite enough to handle a proper Texas thunderstorm.
- Resurfacing layers flaking on older Heights chimneys. The pre-war and mid-century masonry chimneys in the Heights already deal with spalling brick and crumbling mortar from decades of humidity. When a HeatShield Resurfacing System was applied over a failing surface, the new layer can peel as the substrate keeps degrading underneath.
- CeCure sleeve delamination from soil movement. In Meyerland and Braeswood Place, chimneys lean or separate from the house as the clay soil expands and contracts. That movement can cause the HeatShield CeCure Sleeve Relining System to lose adhesion inside the flue, which we catch during a Level 2 camera inspection.
- Efflorescence and rust staining on the exterior. Houston’s persistent moisture leaves white mineral deposits on brick and rust streaks around the cap and flashing. On a HeatShield-lined chimney, exterior staining often means water is getting somewhere it shouldn’t, and the liner should be inspected before the next fire.
HeatShield Service in Houston: What Local Conditions Mean for Your Equipment
Houston’s expansive clay soils are the same gumbo clay that buckles sidewalks in Meyerland, and they do not treat chimneys gently. The cycle is predictable: wet season swells the ground, dry season shrinks it, and the chimney stack shifts with every swing. That movement causes the stack to lean or separate from the house, which puts longitudinal stress on the flue liner. We always check HeatShield liners for vertical cracks at the roofline during cleaning, because that’s where the stress concentrates. You wouldn’t see this same failure pattern in a drier, more stable-soil city like Dallas. What it means for a HeatShield owner in Houston is simple: a cleaning should never be just a brushing. It should include a camera check at the roofline, because that’s where Houston’s soil does its damage. When we find that kind of crack early, the fix is usually a Joint Repair System application and some exterior waterproofing. Catch it late, and you’re looking at a full rebuild.
HeatShield Models & Products We Service in Houston
Our crews clean and repair all four major HeatShield product lines: the Cerfractory Flue Sealant, Joint Repair System, Resurfacing System, and CeCure Sleeve Relining System. We use genuine HeatShield Cerfractory and CeCure products when the repair calls for them, because those materials are engineered to work together. For crowns, flashing, and waterproofing, we also stock quality aftermarket brands like Gelco and Olympia Chimney where OEM adds no benefit. That keeps turnaround faster in Houston without cutting corners on the liner itself. If a HeatShield liner is too far gone or the chimney structure underneath is compromised, we will tell you plainly and recommend a rebuild or a different lining system rather than layering more product on a failing base. Our HeatShield sales & service page covers the full range in more detail.

AfterHeatShield Service Pricing in Houston
A standard HeatShield chimney cleaning and Level 1 inspection in Houston typically runs $189 to $289, depending on access and how long it’s been since the last sweep. Add a Level 2 camera inspection and you’re looking at $299 to $449. HeatShield Joint Repair System work generally starts around $600 and goes up based on how many joints need treatment and how much scaffolding or roof work is involved. A full CeCure sleeve relining typically lands between $3,500 and $6,500, and a complete rebuild with a new crown and waterproofing runs from $8,000 up. The cost driver in Houston is almost always access: steep pitches on two-story brick veneer homes add ladder work, and older Heights rooflines take more setup. Your estimate is free and in writing before anything starts. Call (325) 750-6259 and we’ll give you a real number.

FAQs – HeatShield Chimney Cleaning in Houston
Yes, and it happens even when you never light a fire. Houston’s humidity keeps the flue interior damp for months at a time, and damp clay tiles and mortar are exactly what HeatShield Cerfractory relies on for adhesion. When the liner is rarely heated, that moisture never burns off, and the sealant can soften and peel away from the tile. We recommend an annual Chimney Inspection in Houston for HeatShield-lined chimneys even during years you never burn. Call (325) 750-6259 to schedule one.
Look at the chimney from across the street. If the stack leans or you see a gap between the chimney and the house at the roofline, the soil has moved and the liner took some of that stress. Inside the flue, a Level 2 camera inspection shows longitudinal cracks in the HeatShield material that line up with the direction of the lean. In Meyerland and Braeswood Place, we find these cracks even when the exterior looks fine. The only way to know for sure is a camera.
Usually yes. If the structural masonry is sound and the damage is limited to cracked sealant, eroded joint material, or localized spalling, we can remove the failed HeatShield material and apply a new Joint Repair System or a targeted resurfacing. The chimney itself may need repointing or a new crown, but that’s still far short of a rebuild. We only recommend a full rebuild when the flue tiles are broken, the chimney is leaning enough to compromise structure, or the liner has delaminated across more than a short section. We will show you the camera footage either way before we quote anything.
Water staining on the ceiling near the fireplace, a musty smell from the firebox, white efflorescence on the exterior brick, or rust streaks around the cap are the common tells. After a hard Houston rain, water that got past the crown or flashing can sit against the HeatShield material and start dissolving the joint compound. If you saw any of these after the last storm, have the flue inspected before you burn again. The longer water sits against a ceramic liner, the more material you lose. Call (325) 750-6259 and we’ll take a look.
It can be, but only if the underlying masonry is stable. The Heights has gorgeous pre-war chimneys, and many have already suffered decades of spalling and mortar deterioration. HeatShield Cerfractory applied over a failing brick surface will eventually peel, because the substrate keeps moving and crumbling underneath it. On a structurally sound chimney with minor flue tile gaps, HeatShield is a solid option. On a heavily deteriorated one, we’ll tell you to repoint and waterproof first, then reline. Anyone who skips that conversation is selling you a layer of product, not a fix.
