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.

Why Trust Level Two Chimney Leesburg for Your HeatShield Chimney Cleaning?
We have rebuilt and relined dozens of HeatShield systems across Loudoun County, including Heatshield in Ashburn, so we know how the ceramic coating actually holds up under Virginia humidity and wood-burning creosote loads, without any factory affiliation telling us what to say. Our technicians work with HeatShield materials regularly, and they know where the coating delaminates first, where hairline cracks hide behind what looks like an intact surface, and when a patch will hold versus when a full CeCure sleeve is the honest answer.
Corrine Halstead, our owner, has spent the past several years serving Leesburg’s older homes near the Balls Bluff Battlefield area, where original clay-tile liners still turn up surprises. She shows customers the camera footage herself and points out exactly what was found and what it will cost before any paperwork moves. The camera doesn’t lie, and neither does the price I write down before I start.
Common HeatShield Chimney Cleaning Problems We Fix in Leesburg

- Delamination of the HeatShield coating from the original clay liner. Thermal shock from Leesburg’s hard freeze-thaw cycles causes the ceramic coating to separate where the underlying clay tile expands and contracts. What looks like a bubble or flake on camera is often adhesion failure at the bond line, not surface wear.
- Hairline cracks at flue tile joints where HeatShield’s joint repair was not applied fully. We see this most often on systems relined by contractors who skipped the EcoPrep step. The joint compound needs a clean, profiled surface to bond. Without it, settling in Leesburg’s clay-heavy soils opens hairline cracks within a few winters.
- Moisture intrusion causing spalling behind a HeatShield reline that looked intact on camera. Water enters through a cracked crown or damaged cap, works its way between the coating and the original masonry, and freezes. The coating looks fine from the inside. The damage is behind it. Our camera inspection checks for this specifically by looking for white efflorescence streaks and coating deflection.
- Creosote glaze adhesion on older HeatShield coatings that weren’t smoothed to spec. If the original applicator left the Cerfractory surface rough or didn’t feather the joints, glazed creosote grips it like sandpaper. A standard brush won’t remove it. We use a rotary whip at low speed, then re-inspect to confirm the coating hasn’t been scoured.
- Prefab fireplace units in eastern Leesburg with HeatShield applied to a corroded firebox. In late-1990s subdivisions like Lansdowne on the Potomac and Potomac Crossing, we regularly find HeatShield coatings applied over factory-built fireboxes that were already rusting. The coating can’t fix a structurally compromised unit. Our inspection reports what’s underneath before anyone spends more money on a reline.

AfterHeatShield Parts & Our Repair-vs-Replace Approach
We use genuine HeatShield Cerfractory materials and their proprietary trowel techniques for every reline. Cheap aftermarket sealants don’t bond the same way, and we won’t install them. Leesburg’s humidity and freeze-thaw cycles are unforgiving on substandard materials. That said, we also know when a patch is the right call. If the coating has failed in more than 40% of the flue area, we recommend a full CeCure Sleeve reline rather than trying to patch a failing system piece by piece. Patching below that threshold can buy years of service. Above it, you’re spending good money on a liner that’s already past its service life. Our written quote spells out both options with the exact scope and the exact price for each. Call (571) 601-3174 and we’ll put what we find on camera in front of you.
Our HeatShield Service Process - Step by Step

- 1
Diagnosis. We run a Level 2 camera inspection down the flue, checking the HeatShield coating for delamination, hairline cracks at tile joints, efflorescence, and creosote glaze adhesion. You see the footage after we pull the camera up.
- 2
Repair or reline. If the coating is sound, we proceed with cleaning. If we find joint cracks, we apply HeatShield joint repair compound. If the flue has failed across more than 40% of its surface, we quote a full CeCure Sleeve reline, written and priced before we touch anything.
- 3
Test. We confirm draft performance and check the smoke chamber and firebox for any condition the camera flagged but that couldn’t be addressed from inside the flue.
- 4
Warranty and documentation. You get a written scope, a written price, and a written warranty, plus the photo record from the camera inspection. That’s Clause 4 of the Haven Standard, and it’s included on every HeatShield job we do in Leesburg.
HeatShield Products We Service & Install in Leesburg
- HeatShield Cerfractory Flue Sealant: The core ceramic coating for resurfacing interior flue walls.
- HeatShield Joint Repair System: Fills gaps and cracks at clay tile joints before full relining.
- HeatShield CeCure Sleeve Relining System: Used when the existing flue is structurally sound but the liner needs full resurfacing.

FAQs - HeatShield Chimney Cleaning Service in Leesburg
No. We are an independent HeatShield service provider with extensive hands-on experience installing and repairing their product line across Leesburg and Loudoun County, but we are not a factory-authorized dealer or affiliate of the manufacturer.
Yes. We use genuine HeatShield Cerfractory materials, joint repair compound, and CeCure Sleeve systems. We don’t substitute aftermarket sealants on HeatShield work because we’ve seen how they fail under Leesburg’s freeze-thaw conditions.
A standard HeatShield-lined flue cleaning with camera inspection as part of our Chimney Cleaning & Sweep services typically takes 60 to 90 minutes. Joint repair or a partial reline adds time depending on access and how much of the flue needs work. We’ll give you a written time estimate along with the written price before we start. Call (571) 601-3174 to schedule.
Yes, and that’s exactly what the HeatShield system was designed for. The Cerfractory coating is applied over the existing clay tile, filling gaps at joints and resurfacing the interior. The key is proper surface prep with EcoPrep and a full joint repair pass before the coating goes on. If the underlying clay tile is crumbling rather than just cracked, a stainless steel liner like DuraFlex or Gelco may be a better fit. We’ll show you exactly what the camera found before recommending one path over the other.
Yes. HeatShield is rated for wood-burning flues, and we reline wood-burning systems in Leesburg regularly. The important variable is creosote. Glazed creosote bonds aggressively to HeatShield coatings, especially older applications that weren’t smoothed to spec. After relining, we recommend an annual cleaning and inspection after each burn season, not just for safety but to keep the ceramic surface from accumulating a glaze layer we can’t remove without scouring the coating. Call (571) 601-3174 and we’ll walk you through what annual care actually costs.
We use a low-speed rotary whip rather than aggressive steel brushes for glazed creosote on HeatShield coatings. Properly applied Cerfractory is durable, but it’s not indestructible. Our technicians inspect the surface condition on camera before choosing tools. For routine soot, a standard poly brush is fine. If we see any coating damage starting, we document it and give you a written repair option. The short answer: we clean to the condition of your specific liner, not a one-method-fits-all default.
White streaks on the coating usually indicate moisture moving between the HeatShield layer and the original masonry behind it. This can mean a cracked crown, a failed chimney cap, or water entering through the chase top. What it means for you is this: the problem likely isn’t the HeatShield itself, but the water source above and around it. We’ll trace it and quote the repair in writing. Call (571) 601-3174 for a camera inspection.
In Leesburg’s freeze-thaw environment, a properly applied HeatShield reline with a sound exterior crown and cap typically lasts 15 to 20 years before we start seeing meaningful coating wear. Systems where the crown was compromised or the coating was applied over wet masonry fail much sooner, often within 5 to 7 years, and typically at the tile joints first. The difference maker isn’t the product. It’s what’s around it. We quote what we see on camera, not what the sales sheet promises.
