Water is the number one cause of
damage to your masonry chimney. Rain Caps, Water Sealants and Crown Coats can help your chimney last longer.
Every time it rains or snows that water goes
straight down your chimney unless it is protected with a cap. Also
time it rains the masonry will absorb the water, breaking it down. A
quick fix for crumbling water damaged masonry is called "pointing" and
it is often done, however this is a temporary cosmetic solution, piling new mortar on top of old does not stop water intrusion. Proper water sealant and crown
coating will stop the masonry from absorbing water.

stainless steel or copper rain caps. Galvanized caps rust out in as
little as 1 -2 years, rendering them ineffective and possibly
permanently staining the exterior of your chimney. Stone caps look
traditional, but they can not be removed for proper cleaning of the
flues, have no screening to prevent animal intrusion, and eventually the
stacks that it rests on will deteriorate, and possibly cause the stone
to fall. The stone can also crack into pieces and fall.
Stainless steel and copper caps not only
prevent rain intrusion, they open easily for cleaning flues, they never
need to be replaced because they don't rust, and they are screened to keep
out animals who may want to nest in your chimney (usually squirrels,
birds, bats, and raccoons).
Needless to say we do not recommend the use of
umbrellas to protect your chimney! (It looks humorous but is actually
very dangerous even temporarily).
This is not the same product that you use on
your deck. When fuel burns it gives of water vapor, and that vapor needs
to be able to exit through the masonry. Regular water seal will not
allow this to happen and will result in damage to your chimney. Professional chimney water sealers keep water
drops from penetrating your masonry, but allow water vapor out. Also the
chimney water seal only needs one application every 10 years.
Water sealers don't work as well on masonry
crowns. This is a special rubberized paint that fills in all the small
cracks in the crown and will not allow even standing water to penetrate.
It can't be used on the entire chimney.
Using all 3 of these products together will
keep your chimney looking nice, performing well and keep unwanted
critters out of your house.
