Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!
Dmitry

Lawrence & sons) which began building and contracting in 1903. CSCS cards (Construction safety) and DRB checks held, plus all necessary liability insurances . 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.
We had a porch dismantled and a new exterior door and canopy added. The work was carried out in a timely manner and we were satisfied with the finished work. We would recommend Nigel and his team
