"I used Mothline to help with rising damp that I had. Joe came out free of charge to assess and quote and was very professional and informative. The work that was done was to a very high standard and made sure that mess was kept to a minimal where able to be. All rubbish was taken away the day after completion as mentioned. I would 100% recommend Joe to others for any damp work. Very happy and good competitive prices. Thank you so much."

"Beyond happy with the service from Mothline Preservations for basement damp proofing. Advice given during initial survey was thorough and practical. Joe was very knowledgeable and provided various options to suit budget. The quote was very reasonable and the work was conducted professionally and all left very tidy at the end of the job. The finished product looked great and following the weather that followed I can confirm has made the basement watertight. I've already requested a quote for additional services as Mothline have been amazing to work with on my home improvements."
