From the street, your home is not the only thing that is noticed. People can notice your car, yard, and even your chimney. It may seem ridiculous but it has an impact on the home. Your chimney is subjected to continuously changing climates throughout the year. The blazing hot sun, rising stickiness, driving precipitation, a profound freeze from the outside components negatively affect the brickwork. Keep in mind that bricks are normally strong structure material, but they do take on a lot of wear and tear. The best way to prevent damage from dampness and water is to block with a sealant around the chimney cap.

The chimney cap is located at the top of the chimney. It is best to seal this area along with the area where the chimney connects to the home. Do you wonder what is the best sealant for your chimney cap? Sealants are designed to impede liquids from entering the material it is on. There are two different types used – silicone or polyurethane. Not all sealants are made equivalent. Below are some differences to think about when using a sealant on a chimney cap.

Types of Sealants

Silicone
  • Cures rapidly
  • Cures to a delicate completion
  • Not very useful for high traffic territories
  • Does not hold up to abrasions well
  • Works best on materials like metal, glass, and tile
  • Utilized in any temperature, functions great in the chilly temperatures
  • The life expectancy of 20+ years
Polyurethane
  • Over 24 hours to completely dry
  • Cures to a hard completion
  • Does work well in high rush hour gridlock areas
  • Holds up well to abrasions
  • Works best on wood only
  • Highly difficult to apply in cooler temperatures and does not a strong bond when cold
  • Long term life expectancy

Caps, Covers, & Damper Repairs

Living in the south, mainly along the Gulf Coast, then you know there are lost of rain storms. Actually, we get more rain than anywhere else in the country, including Seattle. The ranking of the most amount of rainfall goes as follows: Mobile, Pensacola, and Seattle in 41st.

This region has such a big deal about rain when it comes to chimneys and fireplaces. As the Chimney Safety Institute of America explains, “water, not fire, causes most chimney damage.”

“Whether masonry or factory-built,” says the CSIA, “prolonged water exposure can result in cracks or gaps in chimneys where creosote can collect and increase the risk of fire or where noxious gases can escape into your home and expose your family to carbon monoxide.”

Fireplaces, Chimneys and Leaks

In basic terms the problem with fireplace and chimney leakage is that water combines with the creosote that remains from fires to form an acidic mixture. Over time that mixture can eat out the silica in the mortar joints.
Once the joints are no longer secure, moisture — remember all that Gulf Coast rain — can get into the house through the chimney. For example, if water comes in through the chimney and is released under the shingles it can lead to the need for a roof replacement.

Also, without proper sealing, heat from fires can travel into areas which should not be exposed to heat, dry out wood, and in some cases actually cause the wood to catch on fire.

In fact, according to a staff report by the US Consumer Product Safety Commission, there are about 22,000 fires a year which are associated with fireplaces, chimneys and chimney connectors. Such fires can cause substantial damage and in some cases may lead to fatalities.

Also, without caps it does happen that birds and animals get into fireplaces. Sometimes nests are built and in some cases animals unable to get out die inside chimneys and fireplaces. Noises and odors can result from such problems.

Caps, Covers and Dampers

You can protect your household with caps, covers and dampers. Caps with spark arresters are devices that go over the flue. They keep out both moisture and animals, plus they help prevent sparks from leaving the chimney. Covers are at the top of the chimney, go around the flue, and protect against moisture. Dampers are inside the chimney itself. They can help create a proper draft to achieve the best fire, plus when closed they prevent animals from getting into the house.
