George has been absolutely amazing, so friendly and professional, was a pleasure and didn't feel like having work done.
The installation has been so quick, no noise issues and completely clean, can't tell anything been done.
Highly recommend, in fact I wouldn't recommend anybody else.
The gathering information process was also brilliant, and Kelsie was so friendly with nothing too much trouble.
