Have you noticed patchy black mould appearing on an internal wall? Or a watermark has suddenly appeared on the masonry? Patchy black mould, watermarks, damp musty smell, and damage to wall plaster roofing and timber are all signs of penetrating damp. Let Preservit Ltd. conduct a damp proofing survey and help you determine what might be saturating your walls with water. Depending on the cause and the extent of damage, we will then employ a suitable damp proofing treatment to prevent future moisture from penetrating into your property. If left untreated, this can lead to more severe issues, such as wood rot, frost damage, and unsightly water marks on walls.
