Had my old felt kitchen extension roof replaced with a rubber roof. Did it all in one day - was super impressed. The guys that did it were friendly and helpful, talking through what needed to be done as well as cleaning out my gutters as well. End result was really tidy, and everything was removed from the site for me. Correspondence was good and staff all helpful. Would recommend in a heartbeat.

Got a few quotes for a small job chasing out mortar and re sealing existing flashing. These guys were the cheapest but also reliable. They do what they say they will and turn up as arranged even in the rain and get the job done to a high standard.
