Damp Proofing

Damp Proofing — Diagnosis & Treatment

Damp problems at home can be frustrating. Whether it's a musty smell, mould on the walls, or flaking paint — it usually means moisture is getting in somewhere it shouldn't. We start every job with a proper diagnosis. Our CSSW-qualified surveyors carry out detailed damp surveys, identify the type of damp (rising, penetrating, or condensation), and explain exactly what's causing it. You'll get a full written report with honest recommendations and a clear cost breakdown. No sales pressure. No guesswork. Just the right solution.

  • Remedial DPC injection — stops rising damp at its source
  • Internal & external membranes for penetrating damp
  • Mechanical ventilation for condensation control
  • Timber preservation for wet and dry rot
