Latest review:
Having just moved into a 3 bedroom house, where one of the bedrooms was far too big for my family's needs, Trevor converted the large bedroom into two smaller ones, thus creating a 4 bedroom home. Everything about the job was undertaken with great care and diligence, the workmanship was of excellent standard, everything was done within the time frame set out and all of my questions and queries were answered in full throughout. Trevor was completely professional throughout the whole process even when I changed my mind about a couple of things.
