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 Repair in Annapolis: What to Know First
HeatShield chimney repair in Annapolis typically runs between $400 and $2,800 depending on whether we’re sealing a small breach or rebuilding a flue section, and most jobs wrap up in a single day. We’re an independent HeatShield service provider, not a manufacturer-authorized shop, which means we tell you plainly when a repair will hold and when you’re better off replacing the liner entirely. This page is for Annapolis homeowners who own a HeatShield liner or Eco-Steel system and need straight answers about what’s failing and what it costs to fix. Call (240) 851-3653 and you’ll get a live person, likely Wendell himself.

If you’re staring at cracking in your HeatShield surface or water showing up in the firebox after rain, you’re in the right place.
How HeatShield Products Fail - and How We Fix Them
HeatShield makes a solid product, but every chimney system has its weak points. Here’s what Wendell and his crew actually see on Annapolis roofs and inside Annapolis flues.
- Eco-Steel liner seam separation at the tee connection. HeatShield’s Eco-Steel Series is a stainless liner with a refractory coating, and the tee body where the liner meets the appliance connector is the most common failure point we find. The thermal cycling from steamy Annapolis summers to cold January burns loosens the mechanical connection, letting flue gas bypass into the chimney cavity. We pull the tee, inspect the seam, and either re-secure with an OEM-compatible band or replace the tee section if corrosion has started.
- Cracked Joints on the Ultra Series. HeatShield’s older Ultra Series liners used a cast-in-place refractory with ceramic blanket insulation. After 10 to 15 years of Maryland freeze-thaw cycles, hairline cracks open at the horizontal joints where sections were joined during installation. Those cracks let moisture into the insulation layer, which degrades it from the inside out. Our fix is selective grinding and re-sealing with a refractory patch that matches the original material, not a generic caulk that burns out in two seasons.
- HeatShield Surfaces spalling in unlined masonry chimneys. When HeatShield was applied directly to old clay tile flues as a surface repair, the underlying tile eventually decays due to age and acid attack from condensing flue gas. The HeatShield layer starts to peel or bubble, and owners mistake it for a failed coating. The real cause is the old tile behind it. We camera the flue first, and if the tile is crumbling, we recommend a full liner like DuraFlex rather than patching a surface that has nothing left to cling to.
- Water entry at the HeatShield crown interface. Even a well-installed HeatShield system leaves a seam where the coated flue exits the chimney crown. Annapolis gets more than 40 inches of rain a year, and that seam is where it finds its way in. We repair crowns and re-seal that transition with a flexible, high-temperature sealant designed for this specific junction. Your flue doesn’t care how the fire looks. It cares how it breathes.
- Improper aftermarket repairs by previous contractors. At least once a month, a homeowner in Annapolis shows us a HeatShield repair that some other company made with brickset mortar or silicone rated for 300 degrees. That stuff fails within the first season. We remove the bad patch and redo the repair with materials that match the original refractory or stainless spec.
Our HeatShield Chimney Repair Process
- 1
You call, a person answers. We gather details about what you’re seeing. If it sounds like a straightforward issue, we book a visit. The number you hear on the phone is the number on the invoice.
- 2
Wendell or a crew member shows up in a window we set, in uniform, with a camera system. We inspect the entire flue from the firebox to the crown, not just the spot you’re worried about.
- 3
We show you the camera footage on site. You’ll see exactly what we see. No mystery diagnosis. Then we walk you through the options: repair what’s failing, or replace if repair won’t hold.
- 4
We decide on parts together. For HeatShield systems, OEM parts make sense where the original material is still solid. When a quality aftermarket part gets the job done for less money, we’ll say so. We’d rather tell you that than hide it.
- 5
The repair happens same visit in most cases. Small jobs take under two hours. Full flue section replacements run half a day. We clean up like we were never there.
- 6
We test before we leave. Draft check, moisture check, camera confirmation. Then we put the 90-Day Done Right Promise in writing. If it’s not right, one call brings the crew back at no cost.
What HeatShield Chimney Repair Costs in Annapolis
We price by the job, not by the hour, and you’ll know the total before a single tool comes off the truck. Here’s what typical HeatShield repairs run in Annapolis right now:
| Repair Type | Typical Range |
|---|---|
| HeatShield surface patching (small cracks, joints) | $400 – $850 |
| Tee connection repair or replacement (Eco-Steel) | $650 – $1,400 |
| Selective refractory re-coating (Ultra Series joints) | $900 – $1,800 |
| Crown repair and HeatShield interface re-seal | $500 – $1,200 |
| Full flue section replacement | $1,800 – $2,800 |
What moves the price: how much of the flue is affected, whether we need to remove part of the crown to access the liner, and whether your chimney has a cleanout we can work through or requires staging from the roof. Annapolis historic homes with tight chase access sometimes cost more for labor time, not materials. We give free estimates, always in writing. And remember: $40 off any repair over $200, no trip charge inside the county, and 10% off for seniors and veterans.

FAQs
It depends on the specific warranty terms and the age of your system. HeatShield warranties often only apply to the original installation contractor’s workmanship, not the coating itself. As an independent HeatShield service provider, we’ll tell you whether the repair might affect any remaining warranty coverage before we start. In most cases, a properly matched refractory repair carries no practical warranty risk beyond the repair area itself. Call (240) 851-3653 and we’ll walk through your specific system.
Sometimes. If the cracks are at joint lines and the underlying flue structure is sound, selective patching works. If the coating is peeling everywhere or the original clay tile behind it is crumbling, a full liner replacement is the honest answer. We’ll show you the camera footage so you can make the call with your own eyes, not our word.
We schedule most HeatShield repairs within a week. If you have water actively entering the home or visible flue gas staining, tell us when you call and we’ll move you up. A live person answers 24 hours a day, so call (240) 851-3653 even if it’s late.
They serve different purposes. HeatShield coats and seals an existing clay tile flue, which can be a good fit when the tile is still structurally sound. DuraFlex is a full stainless liner that’s better when the original flue has failed completely or when you’re changing fuel types. We install and service both, and we’ll tell you which actually fits your chimney. If it doesn’t need doing, we’ll tell you that too.
No. Estimates are free, and there’s no trip charge inside the county. You’ll get a written number before any work starts, and that number doesn’t change when the crew shows up.
If your HeatShield system is acting up, call (240) 851-3653. A real person answers, and Wendell will shoot you straight about what it needs.
