Always get a second opinion
The first step in any flue liner repair is having the system professionally and objectively examined, so you are educated about the options that exist before spending money on a redundant or needless repair.
The only companies that push stainless steel flue liners as the solution for every chimney defect are the ones selling stainless steel.
Certification is not a certificate of honesty or competency
Some homeowners have lulled themselves into believing that if a company claims to be “certified,” it must be competent and honest. Some of the most notorious chimney scammers in the country have advertised as being certified.
Look at the actual list of credentials each company holds beyond certification. Do not be distracted by fluff marketing. We think every chimney professional should have an itemized list of their real credentials right on their website — ours are at the bottom of every page.
Clay tile flue liners
Clay tile flue liners are no different from any other part of a house: they wear down over time. That wear shows up as pitting, chipping, or spalling flue surfaces, along with washed-out mortar joints and cracks in the flue tiles.
Repairing this kind of deterioration is considered routine maintenance. Your existing flue liner does not need to be demolished and replaced with a metal liner unless it is structurally unsound.
98% to 99% of the recreational chimney systems we inspect — even those that have had legitimate chimney fires — can be repaired without demolishing and replacing the existing flue.
Repair can very often be done for less than the cost of replacement with what may be an inferior material.
The HeatShield system
HeatShield® repairs clay flue liners with a resurfacing method. The Cerfractory® sealant restores the flue liner to its original level of safety and efficiency. When there are tears or gaps in the liner, carbon monoxide and other dangerous gases can escape and leach into the home. Those gaps appear because of deteriorated mortar between flue tiles, stress cracks in the tile, or spalled clay liners caused by moisture.
HeatShield can restore your clay flue liner and save you the expense of rebuilding or relining with stainless steel.
