We set the posts in the ground with concrete. Post holes augured (drilled) set and lined making sure that the post holes are straight. All work is warrantied against frost heave for 2 years! We also specialize in sono tube installation for decking. We drill with a mini BOBCAT MT-52 it is a walk-in unit on a rubber track, the BOBCAT is 37 inches wide. We use to be a Perfect Post Hole franchise, over 20 years experience. Many left the franchise and formed independent post/fence companies. We are Master Post Hole (Digger) Inc. and we take pride in our work and listen to our customers. We also take care of the Locates, the clearance from Bell, Hydro, Cable and Gas. You just need to supply the posts and we do the rest! Cheaper Lumber quotes available.
