Penetrating Damp Remedies

Penetrating damp occurs when water infiltrates your property through external defects or internal issues, resulting in damage to your walls, ceilings, and furnishings. To effectively combat penetrating damp, it’s crucial to identify the source of water ingress and implement appropriate repairs. Our qualified damp proofing surveyor can assess your property to determine the cause of the dampness and the extent of required repairs.

Once the source of the dampness is identified, our damp proofing specialists will remove the affected material and apply a physical waterproofing membrane to expedite the drying process. Furthermore, external issues must be addressed, which may involve coating the exterior wall with a chemical water repellent to ensure water remains outside your property, protecting your living space from further damage. Prompt and effective management of penetrating damp is instrumental in preserving your home’s structural integrity and comfort.
