Capped Chimneys Are Safer Chimneys
THE IMPORTANCE OF A CLEAN SAFE CAPPED CHIMNEY
An open chimney is an
invitation to trouble, and
sometimes to disaster.
Any experienced chimney
sweep can tell you; Why Your Chimney Needs A Cap Not only will it keep out critters, birds, small boys and other would-be thieves, but it will protect your chimney especially a masonry chimney from the devastating effects of the weather
1. Rain Damage
Rain coming down an open
flue mixes with soot or creosote,
causing unpleasant
odors and deterioration of flue
walls. It can run down into
the stovepipe, stove, fireplace
insert or furnace, where it
causes rust damage. It can
also rust out a fireplace damper.
Rain plus coal soot forms
sulfuric acid, which is particularly
destructive.
Even in a clean chimney, rain
can damage flue walls, the
smoke shelf and the area down
behind it. Moisture getting
into cracks and mortar joints
freezes and expands, making
the cracks larger.
2. Unwanted Guests
All sorts of pesky critters will
crawl, slither or fly down an
open flue.
Chimney Sweeps
have been called out to evict
(among other things) squirrels,
cats, raccoons, ducks, snakes,
barn owls, an American Eagle,
and even a goose.
Baby raccoons are cute, but
that big wild mama trying to
protect them can be ferocious
and rabid. Raccoon feces often
contain the eggs of a Roundworm
Parasite, Baylisascaris
Procyonis, which can be lethal
to humans.
Birds and their highly-flammable
nests are another common
problem. The nests can
block a flue, or even cause a
chimney fire. An Ohio sweep
removed a dozen dead birds
from a blocked gas flue one
cold winter's night.
The family
had shut down the furnace
because their home's carbon
monoxide alarm sounded.
Chickens roosting on another
open chimney top deposited a
deep sludge of foul manure on
top of the damper. Who could
blame the sweep who refused
to touch that job!!
Hordes of bats flew down the
chimney of one house, driving
the family out. The homeowner
and his neighbors killed 195
bats inside the house. Just prove tha its true that all sorts of pesky critters will
try and crawl, slither or fly down an
open flue.

3. Stuck In The Flue!!
Raccoons and such aren't
the only intruders. People, from children to grown men,
unaware of the anatomy of a
flue, have been known to try to
slip into the house via the
chimney. They can get hurt,
or stuck partway down, and
have to be rescued. The misadventure
can even be fatal.
The remains of a man missing
for seven years were found
when his house and chimney
were torn down by a wrecking
crew. What he was doing in
the flue that became his death
trap remains a mystery.
4. Types Of Flue Caps
A flue cap and screen will
keep out leaves, critters and
rain. It can prevent flaming
balls of creosote from spewing
out onto your roof if there is a
chimney fire. A cap can also
prevent the occasional down-draft.
Some caps are engineered
to solve more-serious
problems with the draft.
Prefabricated metal chimneys
come with their own cap. For
masonry chimneys, a variety
of cap styles, sizes and prices
are available to cover everything
from a single flue to an
entire multi-flue chimney.
They can be made of stainless
steel, aluminum, copper, or
galvanized iron electrostatically
painted. They should be
mounted securely, but not
permanently, as they need to
be removed when the flue is
inspected and cleaned.

5. What About Chimney Pots?
Pitrified clay chimney pots
are also available for topping
off a flue. Originally designed
for use on flues to coal fires,
these are durable and handsome,
but they can restrict the
draft and are not necessarily
suitable for a chimney serving
a woodburnlng fireplace, furnace
or stove.
Some local fire codes require
spark arresters (a type of
screen) on all chimneys. You
definitely need this protection
if you have a shake roof or live
in a wooded area. Chimney
pots, however, are difficult to
screen properly.
6. Call A Chimney Sweep
Installing a cap is a task best
left to a sweep, who is an old
hand at using ladders and
crawling about on roofs. He
can also help you choose the
right cap for your chimney.
The National Fire Protection
Association (NFPA) recommends annual inspection of
flues serving gas, oil and
wood-fueled heating systems.
When you call your chimney
sweep about installing a cap,
it makes perfect sense to go
ahead and schedule an
inspection of all your flues,
fireplaces and heating stoves.

A little professional preventive
maintenance, preferably in
the spring of the year, can go a
long way towards keeping your
family safe and heading off the
possibility of extensive (and
expensive!) chimney repairs
later on and elimniate that creosote smell on damp days.
