I selected Tom Bock among about 10 other professionals called in to install a new gas line through the crawling space in my house. Tom was the first who clearly explained what to expect, what kind of materials will be chosen and why, price structure and what needs to be done to satisfy building codes. Not only Tom made an excellent and beautiful job of installing a new gas line, but he also followed through to make sure building codes are complied with (e.g., range hood vents out, the cabinet clearance is at least 30″ from the surface of the range etc.) The work was done very quickly and safety was my top priority (second one was price, of course!) I am completely satisfied with the work done by Tom and will not hesitate to call him again or recommend to anybody in the Barrie area.
