This place is the best, still a family run business with staff who treat people very well. I will always come back to get products from here and would recommend for anyone to do the same.

Truckers, No docks, they pulled the skids by hand bombing then use the fork lift. They close the receiving by 3:00 p.m.

Two locations, Carp and Ottawa/Nepean. Stop in to say hello, grab some materials, place an order or settle a bill, always good service here.
