Bathroom Fitting- 14 Nov 2018
Jason and Steve did a fantastic job. Jason ensured that I knew what they were doing each day and, when decisions needed to be made, we had a quick chat to make sure we were all on the same page. The work was completed to a high standard and any niggles/snags were dealt with quickly and without fuss. Both of them are polite, respectful and just really nice guys. I would definitely recommend them. In fact, I've already booked them to fit my new kitchen next year.
