Penetrating Damp Treatment - BJ Plastering & Damp Proofing

Penetrating damp is one of the most common causes of moisture problems in UK homes. It happens when water makes its way through external walls, roofs, windows, or damaged building materials. If ignored, it can lead to heat loss, unsightly staining, crumbling plaster, and long‑term structural issues.

What Penetrating Damp Looks Like

Penetrating damp often shows itself through:

• Growing damp stains or tide marks
• Peeling or blistering paint
• Crumbling or salt‑contaminated plaster
