Penetrating damp is caused by water entering a building through an external surface or defect, rather than by moisture rising from the ground. Cracked render, open pointing, damaged brickwork, roofs, gutters, and downpipes can all allow water ingress. Damplast inspects the internal symptoms alongside the outside of Balham properties to trace the route water is taking. The repair plan can include sealing cracks, restoring exterior masonry, applying suitable facade protection, and repairing internal plasterwork or decoration once the source has been addressed.
