Chimney Terms

Chimney Caps

Protective coverings for chimneys usually made of aluminum, galvanized or stainless steel, or copper. Most chimney caps have a mesh screening that serves the dual purpose of spark arrestor and barrier against animals. Chimney caps also prevent rain from entering the flue of the chimney.


Stainless Steel Chimney Liner

Stainless steel pipe, either rigid or flexible, made for relining flues of masonry chimneys when the original clay liner has cracked or broken. May also be used to create a lining in a masonry chimney that was made without a clay liner.


Top-Sealing Dampers

A device installed at the top of a chimney for the purpose of sealing the flue shut when the fireplace is not in use. They are often used as replacements for throat dampers that are installed just above the firebox when a masonry chimney is built. Lyemance and Lock-Top top-sealing dampers are as much as 90% more efficient than throat dampers because they provide a silicone rubber gasket seal rather than metal to metal.

Does Your Home Have An Uncapped Chimney?

If your answer is yes, you need a Gelco Chimney Top. Why? That's simple!
Your chimney is a hole in your roof!

An uncapped chimney:

  • Says "come on in, make yourself at home!" to nesting birds and animals.
  • Allows rain and snow to enter your chimney, which leads to moisture damage and expensive repairs.
  • Creates a fire hazard as burning embers and sparks escape through the open chimney and land on your roof or in your yard.
