Two Relining Methods

Stainless Steel Liner vs. HeatShield Resurfacing

Downtown Greenville's pre-war chimneys qualify for two relining approaches depending on the extent of tile damage and the appliance fuel type. The camera inspection determines which method is appropriate.

Stainless Steel Liner Installation
  • Flexible or rigid stainless liner inserted from the chimney top to the appliance connection
  • Suitable for wood-burning fireplaces, wood stoves, gas appliances, and oil furnaces
  • Correct choice where tile damage is advanced — missing sections, structural cracks, or collapsed tiles
  • 316L alloy for gas appliances; 304 alloy for wood-burning applications
  • Liner is sized to the appliance output — not one-size-fits-all
  • Insulation wrap available where the flue passes through an unheated area
HeatShield Resurfacing System
  • Poured or brushed refractory compound applied directly to the existing clay tile interior
  • Best suited where tile sections are structurally intact but mortar joints have deteriorated
  • Most commonly used for gas appliance flues where exhaust temperatures are lower
  • Restores a smooth, continuous flue surface — improves draft and creosote shedding
  • Does not reduce flue interior diameter as much as a liner insert
  • Not appropriate where tile sections are missing or structurally compromised
Relining Process

How Chimney Relining Works in Downtown Greenville

Relining a pre-war masonry chimney follows a consistent process from camera assessment through liner installation and final draft test.

1

Camera Inspection of Existing Flue

A camera scan from the chimney top documents the full condition of the existing clay tile liner — joint integrity, tile cracking, missing sections, and any obstruction. This determines which relining method is appropriate and what liner diameter is needed.

2

Written Scope and Sizing

Liner diameter is calculated based on the appliance's BTU output, the flue height, and the firebox or appliance opening dimensions. Oversized liners draft poorly; undersized liners restrict exhaust. Correct sizing is documented in the written scope before work begins.

3

Liner Installation

For stainless liner: the liner assembly is connected at the appliance collar, fed down through the existing flue, and terminated at the chimney top with a correctly sized cap. For HeatShield: the resurfacing compound is applied to the flue interior and allowed to cure before use.

4

Top Seal and Cap Installation

The liner is sealed at the chimney crown with a top plate that closes the annular space between the liner and the existing flue tile — preventing water, animals, and cold air from entering the space between the liner and the original tile.

5

Draft Test and Documentation

After installation, draft is verified with the appliance operating. Final documentation includes the liner specification, installation date, and manufacturer warranty information provided to the homeowner.

Wood-Burning Applications

304 alloy stainless liner, sized per NFPA 211 connector area and flue height tables. Insulation wrap recommended where the flue passes through unheated attic or exterior wall sections to maintain exhaust temperature and reduce creosote formation.

Gas Appliance Applications

316L alloy liner for gas condensate resistance. Sized per appliance BTU input and manufacturer venting requirements. Oversized wood-burning flue reduced to correct cross-section for gas exhaust volume — eliminates condensate damage to original tile mortar joints.

Oil Appliance Applications

316L alloy for oil flue condensate. Oil furnace flues being returned to service after a period of abandonment are camera-inspected first — soot and moisture accumulation during abandonment can cause additional tile joint deterioration.

FAQ

Chimney Relining Questions — Downtown Greenville SC

Downtown Greenville's pre-war masonry chimneys were built with clay tile flue liners now 80–130 years old. NFPA 211 recommends relining when tiles show cracking, missing sections, or failed mortar joints — confirmed by camera inspection. Relining is also required when changing fuel types, when adding a new appliance to an existing flue, or after a chimney fire that may have cracked tiles.
The two main methods are stainless steel liner installation and HeatShield resurfacing. Stainless steel liner is recommended where tile damage is advanced or the flue will serve a wood-burning appliance. HeatShield suits flues where tiles are structurally intact but mortar joints have deteriorated, and is most commonly used for gas appliance flues. The correct method depends on tile condition and fuel type — confirmed during the camera inspection.
Stainless steel liner installation approximately $900–$2,500 depending on flue height, diameter, and liner type. HeatShield resurfacing approximately $1,000–$2,800 depending on flue height and tile condition. Full scope and pricing confirmed on-site before work begins.
