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
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.

Relm were fantastic. I have done a lot of renovations over the years but our regular builders weren’t available and we had to get the job done on short notice. Relm were professional, helpful and most notably stayed on time and on budget. I wasn’t able to be onsite and they kept me up to date with photos and videos. They left the building site clean and tidy and I am delighted with the quality of the workmanship. I wouldn’t hesitate to use them again or recommend them to friends.
