    David from IGASS LTD is amazing. His work, attention to details and knowledge is second to none. We have been using David for over 5 years now. Referred him to 5 neighbours as well and they are all very happy with his service. I can't recommend David any more and would never hesitate to use his services.

  • Water pump installation


    Brilliant work carried out. Fitting was not easy as it needed to be in an awkward place with custom made pipes all made on the day. Very happy with the result and would highly recommend.
