Guardian. The Most Advanced Chimney Liner in the World.

The revolutionary Guardian Chimney Liner® is the safest and most effective way of relining masonry chimneys. Using the “cast-in-place” technique, the Guardian system actually eliminates the need to tear down and rebuild an existing chimney, resulting in substantial savings.

Installation Procedure

The chimney is first inspected and cleaned using standard chimney sweep procedures and equipment. Chimneys that have suffered fire & damage often have cracked or broken tiles, similar to those at left.

All lower openings in the chimney structure are closed off and any weak areas in the chimney are braced. All of the existing tiles are then removed from the chimney, ensuring a large cavity in which to size and pour the new liner.

Next, an inflatable rubber former is inserted into the chimney cavity, centered with spacers to ensure proper flue wall thickness, even along offsets or bends within the flue path.

The Guardian mixture is prepared on site by simply adding water. The mixture is then poured into the chimney from the top so that it flows around the form, between it and the chimney wall, filling the entire cavity.

When the Guardian mixture hardens, the former is deflated and removed, leaving a smooth, round, efficient flue passage. The new Guardian liner even shields the walls of the chimney's smoke chamber.

Finally, we finish off the top of the chimney with a crown. With proper maintenance, your Guardian Chimney Liner will provide many years of service.
