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.
HeatShield Chimney Liner & Rebuild in Annapolis: What to Know First
HeatShield chimney liner repair and rebuild in Annapolis typically runs $1,800 to $6,400 depending on whether we’re resurfacing a section of flue or tearing out and replacing the entire liner system. Most HeatShield jobs take one to two days on site, and we hand you a written price before a single tool comes off the truck. If you own a home in Annapolis with a HeatShield liner that’s failing, cracked, or showing signs of water damage inside the flue, this page tells you exactly what we find, what it costs, and how we fix it.

How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory flue sealant cracking at the smoke chamber. We see this constantly in Annapolis homes, especially in the older wood-burning units along the Eastport waterfront. The smoke chamber takes the hardest thermal beating in the whole chimney, and HeatShield’s Cerfractory material can develop hairline cracks there within five to seven years of installation. The camera scan shows it as a spiderweb pattern. We fix it by mechanical cleaning of the chamber walls, then reapplying the HeatShield coating in proper lifts so it bonds and cures before any fire is lit.
- HeatShield’s Joint Repair System pulling away at clay tile seams. This is the failure mode owners never see coming because it’s invisible from the rooftop. HeatShield’s joint repair product fills the gaps between clay liner tiles, but in Annapolis’s freeze-thaw cycles, condensation inside the flue works into those seams and loosens the bond. The symptom is always the same: a faint smoky smell in the house on humid days even when you haven’t had a fire in weeks. The camera reveals the flue wall separating at the tile joints. Fix is resealing the seams with HeatShield’s joint compound after we dry out the flue properly.
- Improper HeatShield application by a previous contractor. Not all HeatShield failures are product failures. We’ve opened up flues in Annapolis where a prior company applied HeatShield Cerfractory over creosote without a proper mechanical cleaning first. That’s not how the material works. The coating delaminates in sheets because it never bonded to the substrate. When we find this, the fix is a full removal back to the original flue surface, a proper cleaning, and a clean reapplication. You can’t put HeatShield on a dirty flue, period.
- Water intrusion at the flue crown causing HeatShield liner deterioration. The flue crown is the concrete cap at the top of your chimney. When it cracks, water runs down the inside of the chimney and attacks the HeatShield coating from behind. We see this in Annapolis all the time because salt air and freeze-thaw cycles eat concrete crowns faster here than inland. If your HeatShield liner is failing and your crown looks like a half-eaten cracker, both have to be addressed or the new liner fails the same way. We rebuild the crown and reline in the same visit.
- HeatShield liner thickness issues on tall Annapolis chimneys. Homes on the Severn River or in Historic Annapolis tend to have tall, narrow flues that are hard to coat evenly. A thin HeatShield application in a tall flue can start spalling, flaking off in layers, within a few seasons. We apply HeatShield in multiple passes on tall flues, checking thickness with a gauge between coats. The manufacturer’s spec is the minimum, not the target.
Our HeatShield Chimney Liner & Rebuild Process

- 1
Call and book. You call (443) 274-4231, a live person answers, and you get a scheduled window. We text when the tech is on the way.
- 2
Camera inspection first. Clause 4 of the Haven Standard requires a documented photo record on every visit. We run the camera down the flue and show you exactly what we see on the screen, then hand you the photos afterward. If the liner is sound and you don’t need work, we tell you that.
- 3
Written price before work starts. We write the scope, the materials, the dollar figure, and the warranty on paper. You sign it or you don’t. No work begins without your signature on that price.
- 4
Diagnosis and parts decision. We assess whether your HeatShield liner needs sectional repair, full resurfacing, or complete replacement with a DuraFlex stainless liner if the underlying flue is too far gone. We explain which one and why, and we show you the camera footage that supports it. Nothing is recommended without evidence you can see yourself.
- 5
The repair or rebuild. We complete the HeatShield application or liner replacement, then run the camera again to document the finished result. You get the before-and-after photos.
- 6
Cleanup and written warranty. We leave the site clean, hand you a written warranty on the work, and you’re done. The 365-Day Done Right Promise covers every job: if it’s not done right, we make it right.

Why Annapolis Homeowners Call Level Two Chimney Annapolis for HeatShield Work

We’ve inspected and repaired HeatShield liners in Annapolis for years, and we’ve seen the full range of what goes wrong with them. Corrine Halstead, our owner, started with a wire brush at a vocational program through LaGuardia Community College and has spent well over a decade doing this work the same way every time: camera first, findings written down, price stated before anything else. The camera doesn’t guess. Neither do we.
Every job comes with a written price, a written scope, and a written warranty before we start. Every visit includes the camera-scan photo record under Haven Standard Clause 4. If you have a written estimate from another company, bring it. We’ll give you a free second opinion on it, and we’ll show you our price in dollars, not vague promises.
We also service DuraFlex and Gelco liner systems, so if your HeatShield liner is beyond saving and a stainless replacement is the honest call, we’re not stuck recommending anything we can’t install. We’re independently owned and operated under the Haven Standard, and as an independent HeatShield service provider, we are not affiliated with or authorized by the manufacturer. We just fix their product when it fails, and we document every step.
FAQs
Most HeatShield liners in Annapolis can be repaired with a sectional application of HeatShield Cerfractory or joint sealant, which costs $1,800 to $2,900. If the liner has delaminated over more than half its surface or the underlying flue tiles are crumbling, replacement with a DuraFlex stainless liner makes more sense. We’ll show you the camera footage before we recommend either one. Call (443) 274-4231 for a detailed written quote.
HeatShield’s warranty is tied to the product, not the installer, so your coverage follows the material as long as it was installed to spec. We document every job with before-and-after camera photos, which gives you a record you can use for any warranty claim. Our own 365-Day Done Right Promise covers our work regardless of what the manufacturer decides.
Most HeatShield liner repairs and rebuilds in Annapolis take one to two days on site. A simple sectional repair at the smoke chamber can be done in a single day. A full flue resurfacing or partial chimney rebuild takes two days. We schedule a specific window, we text when the technician is en route, and we stick to it.
If a HeatShield liner keeps cracking after repair, the cause is usually water getting in through a failed crown, a missing chimney cap, or a previous application that was put over creosote without proper cleaning. We don’t just reapply the coating. We find and fix the water source, clean the flue back to bare surface, and then reapply. If we skip the water fix, the new liner fails the same way. Ask us to show you the cause on camera before we quote the repair.
Yes, HeatShield Cerfractory is rated for wood-burning flues up to its temperature spec, and we inspect Annapolis homes with wood-burning fireplaces every week, including older units along the Eastport waterfront where salt air and irregular use make annual cleaning and inspection a real necessity. If your HeatShield liner has cracked, do not ignore it. A compromised flue liner allows heat and combustion gases into the chimney chase and surrounding framing. That’s how chimney fires start. Call (443) 274-4231 and we’ll run the camera and give you a written price on the same visit.
