The job was booked in straightaway and a team set about taking off old asphalt rebuilding and repairing the big Victorian staircase and then asphalting. The finish was quite amazing, these guys are very skillful at what they do and My husband and I were delighted. They were a professional team really hard working and highly recommend them.” Customer in London

“Ryan and team arrived, late afternoon, as agreed, to review balcony, approx. 25m2, 3 sides fed by tiled roof and one long length hand-rail. Problem, 3 leaks in different places from 10yr old asphalt roof. We discussed the problem and Ryun suggested a choice of two plan of action. We found his quotation very acceptable. This work was completed as agreed, in only a few days, to our complete satisfaction. Eight months after completion, I can now report that after a very wet winter, the roof is in a sound state. An excellent job done.” Customer in Cambridge
