Honest, honest, honest. The service I received from Gas-Tec was by far the best! They were always in contact with me, kept me informed of the price at all time, and made me aware of options available to me. Going forward, I won't be using anyone else for all my heating and plumbing needs. I will be recommending them to all my family who seem to always have trouble finding good, reliable and honest heating and plumbing engineers.
