Chimney relining is the most practical and affordable way to repair deteriorated or damaged chimneys.

Chimney liners are used to protect the inside of a masonry chimney from wear and tear caused by wet conditions. Moisture, over time, will cause decay and corrosion of mortar, clay, and brick liners. How? Moisture reacts with the exhaust gases to form an acid that slowly “eats away” at the chimney. Moisture also, can collect and seep into cracks, mortar and bricks. In colder climates, this moisture will freeze, expand and then thaw, thus causing chunks of the chimney to break and crumble.

As well as moisture…the other most common form of chimney damage is a chimney fire.

In addition to chimney damage, older chimneys may be unlined or their liners may be deteriorated to the point where relining is warranted.

A cast masonry liner is installed after the removal of the old clay tile masonry liner. The tested chimney mix is pumped into the chimney casing and around a temporary deflateable chimney former.

Note the smooth texture and the flow of the Golden Flue masonry lining mix being pumped into the chimney around the rubber chimney former. Note the spring spacers around the former. This device is what maintains the wall thickness of the cast liner throughout the entire length of the chimney system.

The temporary chimney former is removed and pulled out of the chimney after the chimney mix has set up.

The end result is a round seamless liner system with no joints. The cast masonry liner has bonded to the inside walls of your chimney and stopped all further deterioration. At the same time it also has sealed any weak areas and any gaps or cracks in the chimney.

This is a complete fireproof masonry liner which looks like a well casing.

In most cases we install a short piece of conventional clay tile on top of the cast liner. This is so your chimney does not change any of its appearance prior to our relining of the flue.

To complete the job we install a new crown was on top of the entire chimney with same and mortar material.

If this chimney did not have a chimney cap we do recommend one. Water is the number one thing that causes masonry deterioration.
