The revolutionary Guardian Chimney Liner® is the safest and most effective system for relining masonry chimneys. Using the "cast-in-place" technique, the Guardian chimney liner® is not just a chimney liner, but a complete restoration process of the chimney structure.

The development of the Guardian Chimney Liner® is the culmination of 30 years of field experience by the Firesafe Corporation: a company that has installed thousands of cast-in-place chimney liners, in combination with a team of ceramic engineers. The practical applications from thousands of installations united with scientific research and development led to the production of the Guardian Chimney Liner®.

The Guardian Chimney Liner® is tested and listed to UL 1777 by accredited laboratory, Guardian Fire Testing Laboratory, Inc. Additionally, the Guardian Chimney Liner® is the only chimney liner in the United States to be certified by the International Code Council Evaluation Services (Report # ESR-2672) as compliant with the 2006 International Building Code, 2006 International Residential Code, and the 2006 International Mechanical Code.

The proprietary formula of the Guardian Chimney Liner® material provides an insulating, refractory compound that is the only chimney liner approved for zero-clearance specifications with 3/4" liner thickness. This break-through approval is especially critical when the available flue area will only allow a 3/4" liner. Consequently, when the area within the chimney is limited, the Guardian 3/4" minimum liner thickness allows you to line the chimney when our competitors cannot legally do so, since their minimum poured liner thickness is 1" to 1 ½". Furthermore, the Guardian 3/4" standard ensures all installations will meet zero-clearance specifications. The National Fire Protection Agency is strongly considering a mandate requiring that all chimney restoration methods comply with zero-clearance specifications. No problem!


So impressive is the Guardian Chimney Liner® that it is backed by a lifetime guarantee. Please see your chimney restoration professional, or contact us for details.

"Out on Nantucket our chimneys deteriorate faster than on the main land. The Guardian holds up better than any other liner we've installed, especially in this severe climate. We are very impressed with the performance and structural enhancement the Guardian liner provides; our clients are too."

"When we provide our customers with information about the different types of chimney liners we offer, most choose the Guardian chimney liner. Our customers appreciate the protection the system offers, and they also sense our confidence. We never hard sell; we just provide the facts and let the customer choose."

The Chimney Master, Gastonia, NC
"We had a Guardian liner installed in 1999 and had a chimney fire in March, 2009. The chimney sweep that cleaned and inspected the flue after the fire reported that the liner looked 'brand new.' I felt the Guardian liner would be OK because of the research I did when choosing a chimney liner in 1999, but the chimney sweep affirmed my confidence."
