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!

Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

The work completely was of a very high standard with immaculate attention to details. Jerry was punctual from the survey stage to the end of the work. He sorted little snags with the wall, separated the work area with a plastic sheet so the dust was minimised. After each day, my home was left clean and the job was progressing well. The end result looks great and no issues so far. I would recommend them 100%

Daniel provided a competitive quote. I wanted Howdens kitchen and he allowed me to directly deal with Howdens. So in effect I paid the Howdens trader price. The best part was for him to suggest some additional work which made a lot difference. I really appreciate him for that. He charged extra but it was worth it. Daniel and Team worked very professionally and finished the work as agreed. The most important is that Daniel is a good man. I will definitely call him for future work. Highly recommed

Nicolae was punctual, knowledgable and tidy! He tried to identify a leak (turns out the problem may be the washing machine rather than a problem with pipes). He helped rectify the washing machine. He tidied up after himself. Cannot fault him. I have already asked him to return to do other works in my home.
