Cashel Chimney & Roof Repair, Guiding you through Chimney Safety
Getting to Know Your Chimney
Whether you’re preparing your fireplace for a roaring fire, or installing a wood-burning stove, make sure your chimney keeps both you and your house safe.
Here at Cashel Chimney & Roof Repair we are going to guide you through several thing you can do to insure your chimney is always safe. Below are some of the most frequently encountered problems which are the result of inefficient or deteriorating chimneys.
The fire creates excessive soot
The fire creates excessive soot This usually means a lazy and inefficient flue although some bituminous coals are particularly prone to this. Such a flue may not be the right diameter for the fire or stove, or may not be satisfactorily insulated so that the fumes do not rise fast enough and therefore create soot deposits. Excessive soot and tar can be a considerable fire hazard, particularly if the chimney structure has deteriorated; or where, on 19th century property for example, floor joists have been built into the stack, when the whole house can be at risk.
Mortar falls into the fireplace
Mortar falls into the fireplace Bits of brick or mortar falling down the flue indicate a serious deterioration in the chimney structure. Such deterioration normally occurs from the inside of the flue but if there is any indication of weakness on the outside of the chimney then attention is obviously necessary.
There are fumes in the rooms
There are fumes in the rooms These may not be easily detected on closed appliances although if, with an open fire, the chimney smokes back into the room they are then obvious. Fumes contain carbon monoxide and are dangerous. Where there are leaks in the chimney the fumes can find their way into upstairs rooms and attics. Sometimes a tell-tale smoke stain around the edge of a carpet shows the presence of fumes.
The chimney breast feels hot
The chimney breast feels hot This means that the chimney has deteriorated and may be dangerous. A hot wall in the room above may be a similar symptom. If stains also appear on the chimney breast this is a sign that tar or acids have condensed and are eating into the chimney mortar and brickwork.
The fire or stove is using too much fuel
The fire or stove is using too much fuel Large non insulated flues require a lot of heat and fuel to make them draw. In particular high efficiency modern appliances have only a relatively small outlet pipe for the fumes. If these discharge into a much larger non insulated flue, their rise can be decelerated to the point when the appliance just will not draw. An insulated flue of the correct size is required to ensure that an adequate draught is created for them to burn as their designers intended. Otherwise they will use too much fuel and the slow moving fumes will also condense into acids which will attack the internal surface of the chimney.
What are the main fire risks
Fire Risk? Tar and soot deposits are a considerable fire risk; combine this with poor chimney structure or floor joists built up into the stack and the whole house is at risk. The most serious aspect of flue deterioration and corrosion is the fact that the problems are completely hidden from view. This means that you might not be aware of the seriousness of the chimney problem until it's too late. Cashel Chimney & Roof Repairs is here to help you avoid such hazards as:
Tarring of the flue
