Damp Proofing in Gwynedd

Professional damp proofing across Gwynedd — free survey, fixed written quotes and guaranteed work.

S&K Property Investments & Improvement carries out damp proofing throughout Gwynedd — one accountable team from first survey to final finish.

You get a straight assessment, a fair fixed price, and work carried out when we say it will be. Damp is a symptom, not just a stain — and fixing it means finding the cause. We diagnose and treat rising damp, penetrating damp and condensation with the right remedy: new damp-proof courses, tanking, repointing, ventilation and re-plastering with salt-resistant systems.

Our damp proofing service in Gwynedd includes

  • Damp diagnosis and moisture surveys
  • Chemical damp-proof course installation
  • Tanking of walls and basements
  • Penetrating-damp and pointing repairs
  • Condensation control and ventilation
  • Salt-resistant re-plastering

We identify whether the problem is a failed damp course, external water ingress or condensation, and treat it at source rather than just covering it up. Affected plaster is replaced with a proper damp-resistant system so it does not come back.
