DCS-Flex Liner

Due to our volume of business we are able to offer brand name stainless steel chimney liner kits at prices below what the manufacturer will allow us to advertise. These are marketed as our liners but will be a name brand liner with the listed qualities when they arrive at your door.


Homeowner purchase and installation of these liners will still qualify for a full manufacturers warranty on this product. (Most other liners require a certified professional and/or manufacturers recommended installer to keep warranty coverage).


These DCS-Flex chimney liners are a superb buy and are comparable (if not identical) to many if not all of the popular liner brands and will not disappoint.
