We May Be Able To Repair Your Flue Liner with HeatShield®!

An intact and properly functioning flue liner is vital if your chimney is to provide minimal risk and the level of functionality and draft that you need and expect in your home.

Flue liners help:

  • facilitate the draft that pulls combustion byproducts up through the chimney
  • prevent toxic carbon monoxide from leaking into your air supply
  • buffer nearby combustible materials from the high heat that’s produced by your fireplace or stove
  • protect your masonry structure from the caustic elements of combustion byproducts

Many chimneys are lined with clay tile flue liners, and with regular care and maintenance, these liners can provide years of service. However, over time and with use, clay tiles can crack and the mortar joints in the liner can split or degrade. Often, poorly-built chimneys have unsealed joints between the liners from the time they are built.  Damaged or poorly installed clay tile liners increase risk and are inefficient.  They need to be repaired or replaced sooner rather than later.

To repair and restore damaged clay tile flue liners, Blue Sky Chimney Sweeps recommends and installs HeatShield® cerfractory sealant. HeatShield® is made to withstand the high temperatures in your chimney (more than 2900 degrees Fahrenheit), and when properly applied by professional technicians (like the ones employed by Blue Sky Chimney Sweeps), it creates a smoke- and air-tight seal in your flue and carries a 20-year material warranty.

How Is HeatShield® Applied?

Blue Sky Chimney Sweeps’ technicians will inspect your flue liner to assess the level of damage and, if your chimney is a good candidate for this repair, recommend the HeatShield® system that can most effectively repair that damage.

HeatShield® Joint Repair
Flue liners that are largely intact, but have damage in mortar joints, can be repaired using HeatShield®’s Joint Repair System. To apply the product, Blue Sky Chimney Sweeps’ technicians will use a specially-designed applicator blade (that’s custom-fitted to your chimney) to individually fill and smooth all of the cracks and voids in your liner. Once every damaged area is repaired, we’ll scan the entire flue with a video camera to ensure that your flue liner is fully crack- and gap-free.

HeatShield® Resurfacing System
When damage is spread beyond the mortar joints to cracked or spalling tiles, we’ll opt for HeatShield®’s Resurfacing System, which allows us to address the entirety of the flue liner. After applying a preparatory coat to your flue liner, we layer a quarter inch-thick coat of HeatShield® material using a method called “slip casting.” Simply explained, a foam applicator is pulled up through the whole flue with a winch, leaving the correct thickness of HeatShield® material as it travels up the chimney. When the sealant layer dries, we’ll video scan the flue to make sure you have a smooth, smoke-tight chimney.

HeatShield® Makes A Relining Product Too!

If your clay tile liner is too damaged for repair, Blue Sky Chimney Sweeps’ technicians can talk to you about several different relining options, including the installation of a new stainless steel flue liner or the use of HeatShield®’s CeCure Sleeve Relining System. We’ll help you find the best new liner for your system and your home, and install it properly.

If your clay tile flue liner needs repairs, Blue Sky Chimney Sweeps may be able to renew it using HeatShield® cerfractory sealant. Call us today to talk about your chimney and your options or click here to schedule an appointment online.

 

Stainless steel liners offer another chimney lining or relining possibility. We can advise you about the suitability of this product option for your situation.
