Penetrating damp is unsightly and can ultimately end up in costly structural timber rot repairs.To this end, you need to know the signs of penetrating damp, so you can deal with it as quickly as possible.Once the damp problem has been identified and resolved it will take some time for the fabric to dry out and consideration will be given to using specialised drying equipment if this is appropriate to the property.
The damp can form in isolated patches or can affect full wall areas.
The damp can get worse after heavy periods of rain.
This is one of the main reasons why older buildings are affected by penetrated damp as their building materials may be deteriorating over time or have been affected by storm damage and therefore not able to do the job they were designed to do.
If the structure of a building is failing, then your property may be allowing moisture to soak completely through the wall.
Living in the UK, your home is at risk of rainwater penetration, however penetrating damp most often affects areas that are exposed to severe weather conditions or there is a defect in the property like missing roof tiles or defective render, gutters and downpipes.
The first sign of penetrating damp that you may see could be a watermark that appears on your decoration.
A gap or cavity is left between the two walls to protect the inside walls from penetrating damp.
In recent years, dampness has been triggered in homes that have had cavity wall insulation installed.
In the UK, most houses built after 1920 were built with a cavity wall construction to their external walls.
The cavity wall is made up of an inner wall built to surround the inside of the building and an outer wall that could be covered with render, paint or pebbledash.
