Chimney Liner Warranty Comparison Chart: Lifetime Chimney Supply VS. DuraVent

Lifetime Chimney Warranty Requirements

  1. To be covered under the Lifetime Warranty your Lifetime Chimney Liner must be installed by a certified solid fuel installer, in accordance to the written instructions provided with your liner. Any deviations or improper installations will void the warranty.
  2. Annual inspections, maintenance and cleaning must begin one year after the date of the installation and continue once every twelve months thereafter by a certified chimney sweep or a qualified solid fuel professional.
  3. The chimney must have a Lifetime Chimney Supply chimney cap.
  4. Corrosive chemical chimney cleaners must not be used and their use will void the warranty.
  5. Driftwood or wood pellets containing salt, treated lumber, plastics, the chimney sweeping log or trash must not be burned and doing so will void the warranty.
  6. The maintenance record must be up-to-date.
  7. Never use a metal chimney cleaning brush. We strongly recommend the use of a plastic bristle chimney cleaning brush as metal brushes can damage the liner and will void the warranty.

If you should need to make a claim under the conditions of this warranty, you must contact the original installer who will provide Lifetime Chimney Supply, LLC. with information about your claim. Should a factory inspection of the defective parts in question be required by Lifetime Chimney Supply, Lifetime Chimney Supply will pay the shipping cost for the return of the defective parts in question. If Lifetime Chimney Supply deems the parts to be defective, Lifetime Chimney Supply will replace the parts at no cost to the original purchaser and said replacement will be Lifetime Chimney Supply’s exclusive and final remedy under this warranty.
