Whether you’ve noticed damp patches, peeling paint, or a musty smell in your home, our professional damp proofing specialists are here to identify the cause and deliver long-lasting solutions you can trust.

Damp problems can occur in any property and, if left untreated, may lead to structural damage, health issues, and expensive repairs.

Comprehensive Damp Proofing Services in Cornwall

We offer a complete range of damp proofing and moisture control solutions for homes and businesses. Our experienced team can tackle everything from minor condensation issues to major rising damp, ensuring your property remains structurally sound and comfortable to live in.

  • Rising Damp Treatment: Rising damp occurs when moisture from the ground travels up through porous materials such as brick and plaster. This can leave tide marks, flaking paint, and damaged skirting boards.
  • Our specialists use proven damp proof course (DPC) systems to stop rising damp in its tracks, preventing further moisture ingress and protecting your walls from decay.
  • Penetrating Damp Solutions: Penetrating damp is caused by water entering your property through defects such as cracked brickwork, damaged pointing, leaking gutters, or roof faults. We locate the source of the problem and carry out all necessary repairs — including roofing, guttering, and brickwork restoration — before applying long-lasting damp proofing treatments.
  • Condensation Control: Condensation is one of the most common causes of damp in UK homes. It often appears as water droplets on windows and walls, leading to mould growth and unpleasant odours. We provide effective ventilation and insulation solutions to balance airflow, reduce humidity, and prevent condensation from recurring.
  • Basement and Cellar Damp Proofing: If you have a basement or cellar that’s damp or musty, our waterproofing systems can transform it into a dry, usable space. Using tanking membranes and specialist coatings, we create a moisture barrier that protects against water ingress and damp damage.
  • Structural Damp Surveys: Our team provides comprehensive damp surveys to identify the type and extent of moisture issues within your property. We then provide a detailed report and tailored treatment plan to resolve the problem efficiently.
