Chimney Flue Repair
At the Chimney Scientist we specialize in a patented flue repair of resurfacing by FireGuard. This is ceramic system that is listed and labeled to the published U.L. subject 2425 by Guardian Fire Testing Laboratory Inc. This system is designed to fill and repair missing mortar joints as well as cracks in terra cotta flue tile liners.

Open joints and cracks within flue liners create dangerous openings within the chimney venting both fireplaces as well as heating appliances. These openings may allow carbon monoxide to escape the chimney liner and enter the home dwelling. These openings may also allow creosote (a flammable by-product of wood combustion) to build-up outside of the chimney liner and inside the chimney casing. In the event that this flammable flue build-up ignites, extremely high temperatures could be exposed to the house structure and the fire could spread to the dwelling. These chimney fires do occur and it is important that you know your chimney system will safely preventing such a fire from spreading beyond the flue liner.
The National Fire Protection Agency 211 code book states: ““If the flue liner in a chimney has softened, cracked or otherwise deteriorated so that it no longer has the continued ability to contain the products of combustion (i.e., heat, moisture, creosote, and flue gases), it shall be either removed and replaced, repaired, or relined.”
Before the development of this resurfacing technology the sole option for fixing common deterioration of a masonry chimney flue liner would be to remove and replace it with a stainless steel liner (reline.) This can be very expensive making the resurfacing option an attractive cost-effective solution. The chemical and physical properties of FireGuard’s resurfacing technology create and acid, heat, and water resistant reinforced flue liner that will eliminate the seepage of gases through the flue liner.
