Hard Flooring- 2 Oct 2026
Really happy with the flooring work from Remus. He fitted engineered wood flooring in my home office, including removing and disposing of the old carpet, fitting new boards, laying plywood underneath, removing and refitting new skirting boards and painting the room. It wasn’t a straightforward job as the existing floor was uneven and there were gaps around the old skirting but Remus dealt with these and left everything looking neat and well finished. The end result looks excellent and has made a big improvement to the room. Remus was easy to deal with, timely,helpful, and clearly cared about getting the finish right. I’d definitely recommend him to anyone looking for a decorator.
