Alderson Building Services were originally recommended to me by a surveyor when we had a major problem with ingress of water in our kitchen. The work to solve the problem was carried out completely to my satisfaction at the time and I was extremely impressed with the company. It is, without doubt, the best building firm I have ever dealt with and I have been pleased to use them on other occasions since, including this most recent one. At all times the work has been coordinated and carried out to the highest standard in an extremely timely and professional manner.
