  • Just to say thank again. I spoke to my builder and he confirmed that your specialist had attended and given the "all clear" and that your damp work was all now fine and we can finish off our refurbishment.
  • - Nick Mottershead
  • The estimate came promptly, the price seemed reasonable and the work was done with minimum disruption by very pleasant staff. It was a good experience all round.
  • - Stuart Nattrass
  • I would like to thank you for the work you carried out to our house in Chalfont St Giles. We had patches of salts appearing on the walls affected, and recommended a course of action.
  • You organised for your team to come and remove the plaster, inject the damp proofing treatment and replaster the affected area. Your team both at your office and the teams that came out to do the work were professional and friendly. I had to change the start date and your company had no problem accomodating my request.
  • I have no hesitation in recommending you to my family, friends and clients.
  • - Annemarie Shipman
