It is important for tradesmen to point out to homeowners that they must check their chimney flues are not blocked, as it could pose serious threats to their health.Michal Bragg, writing on an entry on Articlesbase, said a blocked chimney flue can lead to carbon monoxide seeping into the home.
Chimney flues can become blocked if birds or animals nest in them, meaning it is vital that homeowners check themselves or bring in a professional to inspect them.
"In the worst cases, the mess left behind may actually block the chimney completely, causing all of the carbon monoxide to dump into the home, possibly building to concentrations high enough to cause death," Mr Bragg said.
Tradesmen should point out to consumers that the summer months are a good time to take care of these issues, as there are fewer jobs around, which means the problem can be fixed more quickly.
They should also make sure that domestic customers who plan to install a chimney liner understand that it is a difficult and dangerous task, according to the Ask the Chimney Sweep blog.
