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 Flue Liner Replacement: The Annapolis Owner’s Guide
We stock and install HeatShield flue liner replacement kits in Annapolis, with most full replacements running $2,400 to $4,800 installed depending on flue height, access, and whether the original liner is still intact enough to serve as a form. If you’re calling us, you’ve usually already been told one of two things: your HeatShield liner has a visible crack, gap, or void on camera, or a sweep recommended replacement after a Level 2 inspection. Either way, you want to know what it costs and whether it has to be done now. The camera answer on that second question is usually yes if the liner has separated at a seam or the underlying clay tiles are spalling into the flue.

Key Takeaways
- HeatShield flue liner replacement in Annapolis typically costs $2,400 to $4,800 installed.
- We carry HeatShield-compatible materials and can match your existing liner’s spec before we arrive.
- Most HeatShield failures we see in Anne Arundel County are joint separation or erosion from salt-air moisture, not old age alone.
- We are an independent chimney service company. We install HeatShield products but are not affiliated with HeatShield the manufacturer.
- Every replacement includes a camera-scan photo record before and after, per Haven Standard Clause 4.
Which HeatShield Models This Applies To

HeatShield is a cerfractory flue liner repair system, not a single product. The two versions we work with most often in Annapolis homes are the Joint Repair System and the CeCure Sleeve Reline System. The first is applied as a sealant at the joints between clay tiles. The second is a full resurfacing of the flue interior using a ceramic-fiber fabric and a refractory coating. If your chimney previously had a HeatShield application and you’re now being told it has failed, the first thing we do is pull the original installation documentation or scan the flue to identify which system was used, because the failure patterns differ.
The compatibility gotcha most owners don’t know: HeatShield is not a liner you can pull out and replace like a stainless sleeve. It bonds to the existing clay tile or masonry. When it fails, the fix is often a stainless steel liner sized to the existing flue dimensions, or a full re-application if the substrate is sound. We match the replacement to the flue’s actual inside diameter, not the nominal size printed on the original paperwork. In Annapolis, where many homes along the Eastport waterfront date to the 1920s through 1950s, the tile dimensions are rarely uniform. We measure on camera and in person before ordering anything.
HeatShield materials are one of several brands we source through our buying network. We also carry DuraFlex and Gelco stainless liners, which are the more common replacement path when a HeatShield application has deteriorated past the point of re-application. As Corrine Halstead puts it: “The camera doesn’t guess. Neither do I.” We won’t recommend a re-coat if the underlying tile is gone.
Before
AfterSigns Your HeatShield Flue Liner Replacement Is Failing
- Flaking or peeling material in the firebox or on the smoke shelf. HeatShield resurfacing material breaks down under repeated thermal cycling. If you find small gray or reddish fragments below the damper, the coating is degrading somewhere above.
- Visible cracks in the flue interior on camera footage. A camera scan will show hairline separations at the tile joints or along the cerfractory surface. This is the most definitive sign, and it’s exactly what we document on every visit.
- A stronger-than-usual smoky smell when the fireplace is not in use. Gaps in the liner allow air to move through the chimney. When humid Annapolis air hits creosote residue, you smell it inside the house.
- Draft problems that got noticeably worse over one season. A failing HeatShield surface creates turbulence in the flue. If the fireplace used to draw well and now spills smoke at startup, the flue lining is no longer smooth or continuous.
- Efflorescence or damp staining on the exterior chimney near the top. A compromised flue liner lets moisture condense inside the masonry. You’ll see white chalky minerals on the brick, usually a few feet below the crown.
Replacement Cost & What’s Included

A HeatShield flue liner replacement in Annapolis runs $2,400 to $4,800 installed for most single-flue residential chimneys. The low end covers a straightforward stainless liner drop into an intact clay tile flue with a standard cap. The high end includes situations where the old HeatShield coating must be removed first, the chimney has an offset, or access requires scaffolding on a steep Eastport roof. We write the number down before work starts. That’s Haven Standard Clause 1, and it applies to every job we do.
Here’s what that price includes:
- Camera-scan inspection and measurement of the existing flue (pre-work, documented).
- Materials: HeatShield-compatible replacement or stainless liner, sized to your flue’s actual dimensions.
- Installation labor by a uniformed, background-checked technician.
- A written scope and written warranty, not a verbal promise.
- Post-installation camera footage showing the new liner in place, top to bottom.
- Removal of old flue debris and a clean work area.
The 365-Day Done Right Promise applies to every HeatShield flue liner replacement we do. If it’s not done right, we make it right. No fine print, no argument.
Can You Fix a HeatShield Liner Instead of Replacing It?
Sometimes, yes. If the original HeatShield application has separated at one or two tile joints but the bulk of the coating is still bonded, a Joint Repair System re-application can close those gaps and buy you several more years. We run the camera first. If the cerfractory surface is intact except for isolated joint failure, we’ll say so and price the repair in writing. If the material is flaking throughout the flue or the underlying clay tiles are cracked, repair will not hold, and we’ll tell you that plainly. You’ll see the footage that made us say it.
DIY or Call Us?

You can safely check a few things before you call. Shine a flashlight up from the firebox and look for loose debris or visible gaps. Note the condition of the brick exterior and whether the crown has cracks. Take photos of anything that looks off. What you should not do is attempt to remove or replace any part of a flue liner yourself. The work happens inside a chimney, often on a roof, with materials that require proper sizing and curing. And the consequence of a poorly done liner repair is not cosmetic. It’s a chimney fire or carbon monoxide moving into the house. This is a job for a trained technician with camera verification, period.

FAQs
In our experience across Anne Arundel County, a HeatShield application lasts 15 to 25 years when the chimney is swept annually and the crown is kept sealed. Salt air and humid summers in Annapolis shorten that if moisture gets in, so liner lifespan here tracks closely with crown condition.
Yes, if the failure is isolated to joint separation and the rest of the cerfractory surface is bonded. We’ll verify that on camera and give you a written repair price if repair is viable. Call (443) 274-4231 to book an inspection and camera scan.
Most single-flue replacements in Annapolis take 4 to 6 hours on site. That includes setup, removal of the old HeatShield material where needed, liner installation, cap fitting, and the post-work camera record.
We stock common liner sizes and HeatShield-compatible materials on our trucks, plus stainless liners from DuraFlex and Gelco for full replacements. If your flue is an unusual size, we order from our supplier network and schedule the install the same week. Call (443) 274-4231 and we’ll confirm what’s available for your flue’s dimensions.
