Existing chimneys can be made safe, durable and efficient by undertaking repair works and general maintenance. Below is a list of the most common repairs that we
If a chimney is leaning less than 1mm in 100mm it is deemed safe. Raking out the existing mortar to a depth of 25mm and repointing with a sulphate resistant mortar will stabilize the lean.
Broken or frost damaged chimney pots can cause smoke blow back so are replaced with new matching pots.
Cracked and loose flaunching allows vegetation to grow. Defective flauching can be removed and replaced with a new sand / sulphate resistant cement flaunching.
Cracks in the projecting cornice can be raked out and filled using special two pack mortars.
Loose and defective rendering is taken off and the brickwork beneath is raked out to a depth of 25mm. Two coats of a waterproof sand / sulphate resistant cement render are then applied.
Defective and loose lead flashings are replaced.
If there are problems with birds roosting between the chimney pots, then we can install bird deterrent spikes. This will not harm the birds, but will prevent them from landing.
