We were delighted with the work undertaken by WJB. Throughout the works they gave advice about the finish for our media wall and other works. Very reliable and cleaned up at the end of each occasion that they worked in our property.. Highly recommend them.

Very pleased with the work done, entire large garage roof replaced, Jordan and the team were very professional and hard working, got the job done sooner than expected as they worked longer days to get it done for us. Jordan took time to listen to our needs and our budget and did his upmost to keep the costs very affordable, without sacrificing on the quality of the work. Each day they ensured everything was clean and tidy. Would highly recommend and definitely use again if needed. Very happy customer
