Caps and Top Sealing Dampers

Chimney Caps

Chimney caps are probably the most inexpensive preventive measure to prevent water leaks, damage to the chimney and birds/critters from nesting inside the chimney. Animal/bird nesting material is usually placed in the chimney during late spring or early summer by these critters and goes undetected until the furnace begins to heat the house in the cool days of early fall. This type of chimney clog is extremely dangerous since carbon monoxide could cause serious consequences to the homeowner.

An uncapped chimney can collect rain water and funnel it directly to the chimney interior. Moisture in a chimney flue can contribute to liner deterioration, interfere with draft and create potential for blockages. Caps also will keep birds and animals out of the chimney, and can prevent sparks from landing on the roof or other combustible materials if there is a chimney fire. Caps should last a long time if they are made of sturdy, durable, and corrosion-resistant material. A full-size chimney cap may be a bit more expensive, but it will cover the entire chimney crown and protect it from wear.

Three reasons every chimney needs a cap:

  1. Rain protection – Moisture often deteriorates flue liners, mortar joints, and can cause fireplace damper mechanisms to rust out.
  2. Animal/bird protection – A source of danger to homeowners is the threat of disease from animals like raccoons, squirrels, birds and rodents that make their home in chimneys. A sturdy well-made chimney cover will help keep those critters out of your home forever.
  3. Spark protection – The mesh screen on our caps protects your home from sparks emitted from your chimney. That means less danger of a fire caused by stray sparks from your fireplace or woodstove.

Top-Sealing Dampers (“Chimalator”)

The three reasons we use top-sealing dampers is to save energy dollars, protect from water damage and to prevent birds/critters from entering the chimney.

Three reasons to use top-sealing dampers:

  1. Save energy dollars. Traditional throat dampers have a metal-to-metal seal. Even when they are new, they leak. That leaking gets worse over time as they rust and warp with heat. That means even when they are closed they allow warm air from your home to escape up the chimney. This adds significantly to your energy costs. Top-mounted dampers seal warm air in 90% more efficiently than even new throat dampers.
  2. Protect your chimney from water damage. Water runs down your chimney and erodes the mortar joints and damages the firebox in your fireplace. Our top-sealing dampers will protect the inner chimney from water damage during those times you are not using your fireplace.
  3. Top-sealing dampers can also prevent animal infiltration. Raccoons, squirrels, birds, and rodents love to move into chimneys. Our top-sealing dampers will keep them out.

Chimalator top-sealing dampers are made of stainless steel parts and assembled to exact standards. They have proven for over 30 years to be the most trouble free top-sealing damper and offer a lifetime warranty.
