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.

Yiltan was quick to come quote and fit us in ahead of both Christmas and our first baby. He was extremely communicative and accommodating of the additional asks we had along the way. His attention to detail is also plain to see. We're over the moon with our kitchen installation and wouldn't hesitate in recommending him to anyone.

We had a great experience with OL & Edward. Livia was amazing and very persistent in finding the perfect replacement for our sink. We were trying to replace a broken sink with an identical version. Our sink had a very particular design and had been discontinued in the early 2000s, but Livia did not stop until she found the exact replacement. John, the plumber who did the replacement did an excellent job, and he was fast, clean and very professional. Highly recommend and would use again!
