Expert Chimney Relining & Replacement

Inside of the brick or stone structure of your chimney, you should see a flue liner — most often, these were built with clay/terracotta tiles, but liners can be made with a variety of other materials, including stainless steel and aluminum.

The liner is performing an important function in your chimney system: It works as a gas-tight and heat-resistant insulator, keeping toxic gases from seeping into your living space and protecting the flammable structure behind the chimney from the effects of high heat. Cracks, gaps or other damage in your flue liner prevents it from doing that important job properly, which is highly inefficient, and highly dangerous — it leaves your home at risk of fire and deadly carbon monoxide leaks.

If your flue lining is damaged, certified Mason’s Chimney Service technicians can install one of a variety of new liners, returning your chimney to its full safety and efficiency.

Why Might My Flue Need Relining?

  • There isn’t a liner – This is sometimes seen with historic homes, but if your historic chimney was built without a liner, this should be corrected as soon as possible.
  • Damaged tiles – Clay/terracotta tile can last when properly maintained, but it’s not uncommon to see cracked, split or flaking tiles after years of use.
  • Damaged aluminum liners – Aluminum liners are affordable, but they’re also prone to rust and corrosion, as well as damage from animals.
  • New appliances bring a need for a resized flue – A new stove, insert or other heating appliance might require a different flue size than the one you currently have. Stainless steel liners can be installed to correct that problem.

Different Options For Repairing Or Replacing A Damaged Flue

Insulated Stainless Steel Lining System
We all know how durable stainless steel is, and pre-fabricated stainless steel liners can be a great, long-lasting option, whether you’re looking to resize your flue for a new appliance or replace a damaged clay liner. When installed by certified technicians, like the ones at Mason’s Chimney Service, stainless steel liners also carry lifetime warranties.

Ceramic Slip Cast Resurfacing
Flue liners that haven’t sustained significant amounts of damage might be best repaired with this kind of resurfacing, which involves coating the liner with a heat-safe Cerfractory Sealant.

Cast-In-Place Lining System
Many view the cast-in place-liner as the most long-lasting option for relining a flue. Homeowners with liners that have significant cracks, gaps and spalling might choose to look into a cast-in-place liner — it will seal those problem spots while strengthening the overall chimney structure. Installation involves inserting a former down the full length of a chimney, then pumping in a liner material that’s similar to concrete. When the former is removed, you’ll have a gas-tight, smooth and seamless liner.
