Because
of their size and beauty, or because of location restoring Historic
homes has become the trend. These home must not only be cosmetically
restored but also functionally restored to meet current health and
safty codes. As part of the process of upgrading the home's heating
system, Chimney Restoration allows for homeowners to use their fireplaces
in a safe & practical manner again.
In
historic homes, the burning of high-temperature heating appliances
such as wood and coal can cause difficulties. Many homeowners &
historic societies concider Chimney Restoration to be an important
part of a Historic Restoration

Chimneys
deteriorate from the inside out because of condensation. In historical
homes, the mortar has a high lime content; therefore, when it gets
wet, it resoftens due to moisture. Eventually, the moisture will
deteriorate the mortar, allowing heat and gases to enter the structure.
Ninety percent of historic homes have wood in direct contact with
the chimney. When wood is new, it has a flash point of 414
degrees F. Subjecting it to heat dries the moisture out of the wood,
lowering the flash point to as little as 200 degrees F. This process
is known as pyrolysis.
After
a chimney fire, people often look down a clay tile liner and see
only hairline cracks, so they then assume that it's safe to continue
using the chimney. What they don't take into consideration is that,
once the flue gas temperatures rise, those hairline cracks can expand
as much as one quarter inch, allowing creosote to leak out behind
the liner.

If
a chimney fire occurs after this, the situation would be the same
as having a chimney fire in an unlined chimney, resulting in a structure
fire and endangering the safety of everyone in your household. In
a research project conducted by the Housing and Home Finance Agency,
it was noted that tile flue liners will crack when temperatures
reach 1400-1700 degrees F. Chimney fire temperatures can reach as
high as 1900-2000 degrees F.
Another
hazard involving tile flue liners is that they have a tendency to
shift, thus leaving an opening between the liners, which allows
creosote to leak out. Very often we have found a large build-up
of creosote behind the flue liner. If you should have a chimney
fire, then the fire will spread from the flue liner into the casing.
There
is a great need for consumer education on the topic of chimney problems
and proper solutions. Have your chimney cleaned once a year,
and do not let any possible damage go unattended.
