Most homes around here feature a chimney, often more than one. In New England we use our chimneys for different purposes.
Most homes around here will have a central heating system, often fueled by oil or gas. Quite often there is a fireplace or two as well. Chimneys can be of single flue or multi flue construction. It is common to find the same chimney serving more than one fireplace. Fireplace and heating system combinations are common. Flues are separate channels within your chimney designed to vent exhaust combustion gases to the outside. The same flue should not vent more than one system and different types of fuel should not share the same flue. Chimneys must endure many years of "wear and tear". Not only the exterior is subject to natural deterioration from the elements, the inner channels/flues can get worn out from exhaust gas corrosion, deposits and moisture. It is important to maintain a chimney in order to safely exhaust toxic products of combustion and to keep masonry structure sound. Flues are made of stacked flue tiles generally made of clay. These tiles are durable but eventually they will start to corrode and break. Once a chimney flue fails, it must be repaired or relined. Since it is not practical to replace the total length of flue tiles, chimney flues are most commonly relined with stainless steel (oil, wood or gas burning) or aluminum (gas only) liners. A quality stainless steel liner properly maintained will last a lifetime. Most modern high efficiency heating furnaces and boilers will also perform better with a properly sized chimney liner. If you are planning on replacing your heating system make sure that you to reline your chimney flue as well. Today's high efficiency systems are not flue tile friendly. Their exhaust temperatures are much lower, therefore the exhaust travels through the flue at a slower page(low draft) creating lots of condensation inside the flue. This moisture mixed with deposits create an acidic environment that will quickly deteriorate clay flues.
All modern stoves and fireplace inserts most likely require the chimney flue to be relined as well.
Now the good news:
Many chimney problems can be avoided with proper maintenance and preventive measures:
Chimney caps, masonry waterproofing, flashing sealant, chimney crown sealant.
A chimney cap can prevent many problems down the road. Every chimney should have a cap!
All caps we install come with a lifetime material warranty.
