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.

It’s unfortunate that I need to give them a poor rating , first instance absolutely great service , however since install the window hasn’t been weighted properly having been told it is . Having to tape it shut says otherwise. Second problem the weight is stuck in the box so now the window doesn’t function. Third issue the window leaks ! It’s hasn’t been sealed properly. Contacted numerous times but had no luck with trying to rectify these issues. No reply after many attempts. Disappointed

I was contacted by many people for the rendering job I needed doing on the house but Owen from Omni Drylining stood out from the others on his approach and explanation of what the job needed. Once they started the work, Owen and his team were superb. Really personable, professional and tidied up as they finished work each day. Owen kept me in the loop and turned up as planned. The end result was second to none. I am absolutely thrilled with the work and have no hesitation in recommending Owen from Omni.

Nicolae was great to work with, very accommodating, quick and unphased by bad weather. Did an excellent job with the blockwork at a good price and a good job with the plastering, which was little bit more expensive, but worth the assurance of having the same person do both jobs. Would recommend for similar, quick turnaround jobs.

George was excellent. Really professional, fast, efficient and reliable. My job required him to travel to my flat three days in a row. And George was always reliable and on time. It was a repair to three damaged walls, filler and paint. George did a fantastic job repairing and painting the walls - they look like new now. The price was competitive too. I am happy.
