With the present weather conditions its no surprise that older homes are being effected by Penetrating Damp were rainwater enters the property through solid walls with no cavity. Now whilst the first port of call should be to check for defective rainwater goods (gutters and downpipes) and to maintain mortar there is still always the posibilty of ingress particularly around windows and doors.
Probably half of all the calls we get that relate to penetrating damp (rainwater entering the building directly through the walls at any floor) have been impacted in some way by faulty or incorrectly fitted rainwater goods. Overspill from gutters and downpipes can saturate a wall and ingress the building particularly when the walls are of a solid construction.
As the weather improves gutters and downpipes will have less work to do and probably be furthest from your mind however this is the time to check and replace them, if needed, or at least give them a good clean.
We were asked by a Bristol letting agent to complete a survey on a one-bedroom ground floor flat converted from an end of terraced house.
