All About HeatShield - Boston MA - Billy Sweet Chimney SweepWhen it comes to chimneys, it is our personal and professional goal to make sure all of our customers are safe and comfortable this winter. We strive to further this goal by providing expert services to maintain and restore chimney systems to safety and efficiency. One of the most common services that older chimneys require at least once in their lifetime is a flue liner repair or replacement. At Billy Sweet Chimney Sweep, we trust HeatShield for liner repairs—big and small.

HeatShield Meets Industry and Environmental Standards

In over 20 years, HeatShield has revolutionized the chimney industry with products that protect and last. HeatShield Cerfractory technology is a specially formulated hybrid that combines ceramic and refractory materials to safeguard against heat, moisture, and corrosion in the chimney system. HeatShield Cerfractory Flue Sealant has stood up to lab testing, is rated “super-Duty” by the American Society for Testing and Materials, and surpasses all fire safety codes set by the National Fire Protection Association (NFPA) and the International Residential Code (IRC). This product is approved for all fuel types, which means you won’t need to convert the liner if you convert fuel types in the future. On top of every other great benefit of using HeatShield products to fix your chimney, HeatShield is also considered eco-friendly, made from recycled and natural products at a lower cost than alternatives that are less “green”.

HeatShield Installers are Expert Installers

Independent HeatShield Installers are selected, trained, and certified as HeatShield installers. It is not a program you can pay your way into, but one you earn. Our technicians have factory training and tools designed specifically for HeatShield products. Armed with the right knowledge, experience, and tools to get the job done, we can repair your liner whether you have small joint damage or need a major relining.

HeatShield Repairs

Using HeatShield Cerfractory Flue Sealant, we are able to repair joints, missing mortar tiles, and more. We simply cut and place a custom foam applicator blade beneath the damaged portion of the flue, then attach the blade to a winch at the top of the flue opening. HeatShield product is then mixed from powder, placed into the blade, and deposited into the gaps and cracks as the blade is pulled upward. This process can be repeated for however much damage is present, however, if the damage is extensive, the flue may need to be completely resurfaced.

A resurfacing application uses the same process, but the applicator blade starts at the bottom of the flue and is pulled up to the top, surfacing the whole flue with HeatShield Cerfractory Flue Sealant. Once the entire flue is coated, we use cameras to verify the repairs are made properly.

CeCure Sleeve Relining

In serious cases of flue liner damage, or when no liner is present at all, we can reline the flue with a CeCure Sleeve: thin, ceramic insulation, reinforced with stainless steel fabric. The sleeve is sandwiched between two coats of HeatShield Cerfractory Sealant, creating a long-lasting liner, safe for all fuel types.

HeatShield is the easiest and most cost-effective solution for flue restoration. Professionals are so sure about HeatShield that it comes with a limited lifetime warranty. Really! Ask your chimney professional today.
