If the internal walls of your home are plagued by dampness, you will need to take care of this before adding insulation. If not taken care of, insulation can cause further damage to both the wall and your insulation by trapping moisture. To avoid any future issues with dampness, use damp proof materials to line your wall before repainting it and installing new insulation. If installed properly, solid wall insulation will not cause or exacerbate damp problems. Prior to beginning any work, installers will do a thorough inspection of your property to confirm that it is in good condition overall and that the walls, floor, and ceiling are dry. This would entail attending to current dampness issues as well as problems such as cracked bricks, missing mortar between joints, or waterlogged gutters which could pose difficulties down the road.
