I recommend Andy from Rowland Property services, he has done a front room back to brick and replaster for us before and also redid our bathroom which needed structural alterations to the wall. Better than some bathrooms fitters on here as he does the whole job, another guy i got a quote from said i needed to get a builder in to do the wall knocking through work which would have been a pain.
Throughout the job he was very flexible, kept us informed, adapted to problems that raised along the way, and the finish of the job was great. I got 4 quotes and he was value for money, and was fine with me sourcing my suite/materials too. All in all someone you can trust.
