This is the most important time of the year to get your chimney or stove flue swept. Clearing soot prevents it getting damp over the summer, resulting in a tar or creosote build up. These are highly flammable and are the principal cause of chimney fires.
As a professional Guild of Master Chimney Sweeps member we always advise customers to have their appliance swept in late Spring or early Summer. This maintains the integrity of the flue - especially where stainless steel liners are under guarantee subject to correct maintenance.
Even if you only have your chimney swept once a year, now is the time to have it done so your burning cycle and sweeping cycle are working together to keep you and your home warm and safe.
