Found Jason based on the reviews here and he more than lived up to his rep. A wonderful guy, with a polite and neat crew, took out the old concrete floor in the basement - which was only about 1/2" thick and had been patched many times since over the home's 95 year life - installed internal weeping tiles, laid down a gravel base and poured the concrete. Because of our narrow laneway and poor access, the concrete had to be mixed inside and ended up being more work than he originally thought. Despite that, the floor ended up perfectly level and there was no request for more money when the job was done. Once the window was out in the basement, the guys came and went through the window to keep the upstairs clean. When I need masonry work in the future, Jason will be my first call.
