Stop the energy thief...your fireplace damper

Traditional fireplace dampers leak. They leak a lot. That costs you big money in lost utility dollars going out your chimney.

A Lyemance Top-Sealing Damper will change all that. This well constructed, superbly engineered damper eliminates 90% of the winter heat and summer cooling loss that leaks past your current damper. It also eliminates downdrafts and keeps moisture and animals out of your chimney and home. Moisture in your chimney causes unwelcome odors and leads to deterioration of bricks and mortar. The Lyemance Top-Sealing Damper works year round to protect your chimney. That's why thousands are installed each year.
