Each year, it is important to make sure your chimney is free of creosote buildup and your firebox is nice and clean (no black walls). Cleaning and inspecting a masonry fireplace and chimney is a messy job that requires a trained eye. In addition to properly cleaning the entire unit (chimney liner, firebox, and all components of the chimney), proper fireplace maintenance is also mandatory. Hot gases must be able to travel up and out. Gaps in a system will cause hot gases to get into the chase or the home which can cause a fire or it can also cause carbon monoxide to enter your home. Most people are not aware of this, but unclean chimneys are a primary cause of carbon monoxide poisoning in homes. If you do not maintain and clean your chimney annually, you run the risk of creating a serious fire hazard when you least expect it.
A trained professional has the right equipment to identify any risk factors as well as remove creosote buildup. When creosote buildup gets to 1/8 of an inch thick, it becomes a serious fire hazard as it is highly flammable. It can appear like black flaky tar coating your chimney and if it is extremely bad, the surface will be smooth from repeated recoating. Once it is thicker than 1/8 of an inch, the flammable creosote in the chimney can easily catch fire from the flames below. A professional chimney sweep will ensure all creosote is scraped off your chimney liner and firebox in a clean efficient way, which does not allow any soot to enter your living area. If it is determined that the creosote is too thick for removal, a replacement of your chimney liner is the safest option.
1.
First, they place a
drop cloth or canvas tarp is in
front of fireplace, with at least a
five foot radius surrounding the
fireplace area to catch any creosote
(aka: soot) that will disperse into
the room.
2.
If there is a large
amount of ash that has accumulated
in your firebox, they will scoop it
out first.
3.
Then, they will
remove your fireplace grate, so they
can access your chimney free of
obstructions and inspect the firebox
for any hazards.
4.
They will then tape
a poly sheet over the fireplace.
It will have a hole in it to
attach to their industrial vacuum
cleaner.
5.
Next, they will
inspect the chimney to determine
level of dirtiness and safety.
Most sweeps will drop a
camera with from the rooftop to get
close up views of the chimney liner,
damper, smoke shelf and firebox from
all sides. It is
important to know that a chimney
deteriorates from the top downwards,
so inspection from the rooftop is
vital.
6.
After ruling out
any hazards such as cracks in the
liner, a collapsed liner, or any
other obstructions, it is time to
clean the chimney.
7.
They will scrub the
flue, smoke chamber, smoke shelf,
and damper with a professional
chimney brush that meets the
dimensions and proper material match
for your chimney.
8.
Once they have
sufficiently removed all creosote
buildup, they use a shop-vacuum
(preferably one with a micro filter
to prevent airborne dust) to vacuum
the fallen soot from your firebox
and within your smoke-chamber and
smoke-shelf areas.
The best time of year to have your chimney and fireplace serviced is the spring or summer. This is because it is outside the peak winter season when people are using their fireplaces and notice they have a problem with their chimney. If you wait until you want to use your fireplace to have it cleaned and inspected, you will have to wait for your sweep's schedule to permit. Another side note, some chimney sweeps will offer discounted pricing if you contact them to do your annual cleaning outside of their busy season.
A chimney sweep is a licensed professional who knows the inner workings of your chimney, fireplace, and heating appliances. Chimney sweeps are able to detect potential fire hazards that the average homeowner does not see because they are hidden deep in the chimney or in some cases, homeowners do not know what to look for. Chimney sweeps have the professional equipment and understand the latest state laws and safety codes that will prevent a chimney fire from happening in your home. If you have just purchased a new home or a natural disaster has occurred in your area, this is all the more reason to hire an expert and make sure your chimney is clean and safe to use before lighting your next fire.
