Stainless steel flexible liner installation for cracked clay tile replacement, fuel conversion, and new appliance connections. CSIA certified installation with written price before work begins. All Greenville SC neighborhoods served.
The flue liner is the only barrier between the combustion gases in your chimney and the wood framing of your home. NFPA 211 requires a sound, properly sized, code-compliant liner for any chimney in active use. When the liner fails — or is absent or wrong-sized — relining is required before the chimney can be used safely.
Clay tile liners in Greenville SC homes built before 1985 frequently present cracked sections found on Level 2 camera inspection. A cracked liner allows combustion gases and sparks to reach the surrounding masonry and woodwork.
Even a chimney fire of short duration can crack the full length of a clay tile liner. NFPA 211 requires a Level 2 inspection after any chimney fire. In most cases, chimney fire damage requires relining before the chimney returns to use.
Converting from wood to gas, or installing a gas insert in an existing wood-burning fireplace, often requires a stainless steel liner sized for the new appliance. Gas appliances vent at lower temperatures and require a smaller, tighter flue.
A flue that is too large for the connected appliance causes incomplete combustion, excessive creosote buildup, and poor draft. A flue that is too small causes backdrafting and carbon monoxide risk. Relining corrects both conditions.
Many Greenville SC homes built before 1940 — common in North Main, Augusta Road, and Downtown neighborhoods — were constructed without a flue liner. A stainless steel liner can be installed inside the unlined masonry chase.
Installing a new gas furnace, water heater, or boiler that vents through an existing chimney commonly requires a new properly sized flue liner. Undersized venting is a leading cause of carbon monoxide issues in Greenville SC homes.
Three main liner systems are used in the Greenville SC market. The right choice depends on the appliance fuel type, chimney configuration, and existing structure. We assess and recommend after inspection.
Corrugated stainless steel flexible liner is the most commonly installed relining solution in Greenville SC. Available in 304 grade (for gas/oil) and 316Ti grade (for high-temperature wood burning), flexible liner is installed from the chimney top and navigates bends and offsets without difficulty.
Rigid stainless steel sections provide a smooth interior wall that is slightly easier to clean than corrugated flexible liner. Rigid liner requires a straight chimney without offsets or bends. Used primarily on newer Greenville SC homes with straight-shaft chimneys.
A castable cement compound is poured or pumped into the flue around an inflated form, creating a custom-cast seamless liner that conforms to the exact shape of the existing masonry chase. Particularly effective for irregular-shaped or heavily deteriorated flues.
Before any liner work, the existing flue is camera-inspected to document liner condition, measure inside dimensions, identify offsets or bends, and confirm the correct liner size for the appliance connected.
Liner diameter is calculated based on the appliance heat output (BTUs) and flue height — per manufacturer specifications and NFPA 211 requirements. Written price provided before ordering materials.
The existing flue is cleaned of all debris, creosote, and loose tile fragments before liner installation. Drop cloths protect the interior; HEPA vacuum captures debris.
For flexible liner: the liner is attached to a pulling cone and lowered from the chimney top. For rigid liner: sections are connected from below and raised into position. The liner is secured at top and bottom with properly rated connectors and clamps.
For gas appliances and high-efficiency units, liner insulation wrap is installed to maintain proper flue temperature and prevent condensation issues in Greenville SC's humid climate.
After installation, the liner connection is tested, the firebox connection confirmed, and the top termination sealed. Written completion report with photographs documenting the installed liner system.
CSIA certified liner installation with written price before any materials are ordered. All Greenville SC neighborhoods and surrounding areas. Level 2 inspection required first — we can schedule both.
