Key Takeaways

• HeatShield resurfacing works when the original liner is structurally sound; it does not fix a liner that’s already collapsed or separated.
• Camera inspection is the only way to confirm which condition you have. We’ve done it this way since 2009.
• You’ll get a written price, written scope, and written warranty before any work starts. No exceptions.
• Leesburg’s freeze-thaw cycles punish masonry chimneys, which is why we check the crown and exterior before blaming the liner.

How HeatShield Products Fail - and How We Fix Them

HeatShield is a cerfractory resurfacing product applied inside an existing flue. It’s good material. It still fails, and the failure points are predictable once you’ve seen enough of them in Leesburg homes.

• HeatShield Joint Repair System (JRS) fails at the mortar joints first. The product seals joint gaps between clay tile sections, but if the original clay tiles have shifted due to the freeze-thaw cycles we get in Leesburg winters, those joints reopen. We find gas and carbon monoxide drafting into the wall cavity when this happens. The fix: camera-scan the full flue, confirm the tile alignment, and reapply the joint seal only if the structural tile work is still intact.
• HeatShield CeCure (Smoke Chamber System) cracks where the smoke chamber meets the flue transition. The smoke chamber is the funnel-shaped area above the firebox, and it takes more thermal abuse than any other part of the chimney. We see hairline cracks there that let heat and gases reach the framing. The fix requires full access through the firebox, proper surface prep, and the CeCure resurfacing material applied in consistent coats, not one thick pass.
• Original HeatShield’d liners from the early 2010s show surface erosion after 10-12 years of wood burning. This isn’t a manufacturing defect. It’s what happens when a homeowner burns unseasoned wood or skips annual sweeps. The cerfractory surface degrades and flakes. If caught early, we can resurface the affected section. If the erosion has exposed the underlying tile, replacement is cheaper long-term than repeated patching.
• Improper DIY or handyman application is the failure we see most. HeatShield requires specific surface prep and coating thickness. We’ve pulled apart liners where someone essentially painted the flue with a thin coat and called it done. It delaminates within one season. Our repair protocol strips the failed application back to sound substrate and redoes it properly.
• Full HeatShield CeCure liners fail at the flue terminus when the crown has cracks. The top of the flue is where water entry starts. If the crown is spalling (flaking and crumbling), water seeps down, freezes, and breaks the cerfractory bond from the top. We don’t resurface a liner under a failed crown. Crown repair or replacement comes first, then the liner work, or you pay twice.

Our HeatShield Chimney Liner & Rebuild Process

We follow the same sequence on every HeatShield job because skipping steps is where warranties die.

1. 1
   Camera down the flue. We run a full NFPA 211 Level 2 camera scan, which means the camera goes up from the firebox and down from the crown if needed. You see the footage. We point out exactly what’s failing and what it means.
2. 2
   Written diagnosis and price. Before any tool touches the chimney, you get a written report with photos, a written scope of work, a written price, and a written warranty. This is Haven Standard Clause 1, and we’ve operated this way since 2009.
3. 3
   Parts decision: OEM HeatShield or a DuraFlex or Gelco alternative. When a HeatShield patch is appropriate, we use HeatShield material. When the liner is beyond resurfacing, we quote a stainless liner from DuraFlex or a cast-in-place system from Gelco, depending on the flue configuration and what the camera told us. You make the call with the numbers in front of you.
4. 4
   The repair or rebuild. Surface prep, then application or installation. Our techs are trained on HeatShield application thickness and curing requirements, and they work clean: drop cloths, shoe covers, and no debris left in the living space.
5. 5
   Post-work camera verification. We run the camera again after the work cures or the liner is installed. You see the before and after. The photo record is yours to keep under Haven Standard Clause 4.
6. 6
   Written completion record and warranty. You get a documented record of what was done, with images, plus the 365-Day Done Right Promise: if it’s not done right, we make it right.

What HeatShield Chimney Liner & Rebuild Costs in Leesburg

Here are the numbers we see across Leesburg, including older homes near Balls Bluff Battlefield where the original clay liners still show up.

• HeatShield Joint Repair (JRS): $1,800 – $2,800 depending on flue height and access.
• HeatShield Smoke Chamber (CeCure) resurfacing: $2,400 – $3,800.
• Full HeatShield flue resurfacing: $2,800 – $4,200 for a single-flue residential chimney.
• Stainless steel liner replacement (DuraFlex or equivalent): $3,500 – $6,500 installed, depending on flue size, height, and whether an insulation wrap is needed.
• Full chimney rebuild from the roofline up: $8,000 – $20,000+, since this involves masonry, crown, and flue work together.

What moves the price: flue height, roof pitch and access, whether the existing liner has collapsed, and whether the crown or smoke chamber is involved. A two-story chimney on a steep Leesburg roof costs more than a single-story ranch. We give you the written number in advance, and if you bring us a competitor’s written estimate, we’ll give you a free second opinion on it.

Why Leesburg Homeowners Call Level Two Chimney Leesburg for HeatShield Work

Corrine Halstead grew up in Queens, where old buildings keep secrets behind their walls, and she spent years working through every flue configuration the Northeast could throw at her before bringing that experience to Leesburg. When she’s on your job, she shows you the camera footage herself and points out exactly what was found and what it costs before any paperwork moves. The camera doesn’t lie, and neither does the price I write down before I start.

That’s the standard every job is held to. We’re not here to sell you a liner you don’t need, and we’ll tell you plainly when a chimney can safely wait a season. But when the flue is compromised, we want you to know why, see it with your own eyes, and have the written price in your hand before you decide. We also service DuraFlex and Gelco systems, so if the right answer for your chimney isn’t a HeatShield repair, we’ll say so and quote the material that actually fits. Every visit includes a camera scan and photo record. Every job carries the 365-Day Done Right Promise. And when you call (571) 601-3174, a live person answers, day or night.
