Chimney Flue Liner Repair & Relining

The flue liner is the innermost component of your chimney, and it serves a critical safety function: containing combustion byproducts — including carbon monoxide and extremely high temperatures — and directing them safely out of your home. Over time, clay tile liners crack and spall, and the mortar between liner sections deteriorates, creating gaps through which gases and heat can escape into the surrounding masonry and adjacent wood framing. Morales Brothers Chimney Service offers both targeted flue tile repair and complete stainless steel liner installation for chimneys where the original liner has failed beyond repair.

Stainless steel flexible liner systems are the most durable and widely recommended solution for damaged flues. We install 304 and 316 alloy liners appropriate for wood-burning, gas, and oil appliances, sized correctly for your specific fireplace or heating appliance to ensure proper draft and prevent downdrafting. Each liner installation includes a top plate, rain cap, and insulation wrap where required to maximize efficiency and condensation control.

In cases where only a section of the clay tile liner is damaged, we can perform targeted repairs using a pourable refractory compound that bonds to the existing liner and fills cracks and voids without requiring a full relining. Our video inspection process identifies the precise location and extent of liner damage so you only pay for the repair that is actually needed. A properly functioning flue liner is non-negotiable for safe chimney operation — don't delay if your inspection has revealed liner damage.
