HeatShield Chimney Flue Restoration Services

HeatShield is an advanced chimney flue restoration technique designed to repair and restore damaged flue liners without the need for a complete replacement. Developed by SaverSystems, HeatShield is a highly effective ceramic coating that seals cracks, gaps, and defects in your chimney’s flue liner, providing a smooth, durable, and heat-resistant surface.

At Nexus Chimney Services, we specialize in HeatShield flue restoration, offering homeowners an eco-friendly, cost-effective solution to bring their chimney venting systems back up to modern NFPA 211 standards.

When is HeatShield Needed?

Chimney flue liners endure significant stress from heat, moisture, and combustion byproducts. Over time, this can lead to:

  • Cracks or Gaps in Flue Tiles: These defects allow heat and toxic gases to escape into the chimney structure.
  • Erosion of Mortar Joints: Worn joints between flue tiles can compromise the liner’s safety and functionality.
  • Creosote Buildup: Rough or damaged surfaces in the flue increase creosote accumulation, raising the risk of chimney fires.
  • Water Damage: Moisture entering the chimney can weaken the flue liner, leading to spalling and other structural issues.

HeatShield is an ideal solution for addressing these problems without the extensive labor and expense of a full flue replacement.

How Does HeatShield Work?

HeatShield uses a proprietary ceramic-based formula to repair and restore flue liners. There are three primary applications depending on the extent of the damage:

1. Joint Repair

  • When It’s Used: For flues with eroded or missing mortar joints between clay tiles.
  • Process: HeatShield is applied directly to the joints, sealing gaps and restoring structural integrity.

2. Resurfacing

  • When It’s Used: For flues with surface damage, minor cracks, or spalling on the flue liner.
  • Process: A layer of HeatShield is evenly applied to the entire flue surface using specialized tools, creating a smooth, seamless lining.

3. Slip Casting

  • When It’s Used: For flues with extensive damage or multiple cracks.
  • Process: A foam applicator is used to coat the interior of the flue with HeatShield, filling larger gaps and creating a completely restored liner.
