City and Guilds trained at Bucks University College in cabinet making. Recommendation "We have recently employed NML Contracts to undertake work on our house of a challenging nature and for which the usual jobbing builder and plumber declined to quote. NML Contracts have demonstrated skills and initiative in dealing with the unexpected and produced a thoroughly satisfactory and pleasing result which has materially improved the attractiveness and serviceability of the house . The work included incorporating a porch into the lounge area , requiring an RSJ some 4.4m in length, In the course of construction t was found that the roof was concrete and was supported by the outer skin of the house, whereas the roof of the house was conventional timber and was supported by the inner skin. It was therefore necessary to use the RSJ to support the concrete and provide suitable timber supports for the main roof . This was done most expertly and quickly and was approved by the building inspectors. All energy conservation requirements were fully met . The work also included two en suite bathrooms for which pumped drainage was necessary " Satisfied customer , D.G.W.

Coopers provided an excellent service. Jack came and reviewed the problem, showing me photos of the leak and damage, and gave various options and prices of what I could do. In the end, I decided on a full roof replacement along with guttering and soffits. I got them to fit a Velux window and sun tunnel too. The project management was excellent. Scaffolding came within a day and work started following Monday. The job was completed in four days to a professional standard. Highly recommended.
