How We Help With Chimney Relining

The flue liner is the most critical safety component of any chimney system—it contains combustion gases and protects surrounding combustible materials from excessive heat. When clay tile liners crack, spall, or separate at the joints, the chimney becomes a fire and carbon monoxide hazard regardless of how clean the flue is. Hill Brothers Chimney Sweeps installs flexible and rigid stainless steel liner systems sized to match your specific appliance's venting requirements, restoring the chimney to safe, efficient operation.

For masonry chimneys with minor to moderate liner deterioration, we also offer HeatShield Cerfractory Flue Sealant application—a spray-applied ceramic restoration product that repairs cracks and voids in existing clay tile liners without full liner replacement. This can be a cost-effective solution when the tile substrate is structurally sound but the mortar joints and tile surfaces have degraded. Our technicians perform a thorough pre-liner video inspection to determine which approach is appropriate for your specific flue condition.

Relining is also required when converting a wood-burning fireplace to a gas insert or when upgrading to a higher-output wood stove, as the new appliance may require a different flue diameter. All liner installations by Hill Brothers are sized per manufacturer specifications and current building code to ensure proper draft and safe operation for the life of the appliance.
