My experience with them or other pole building contractors was not the best. First of all, I don't like to have to stand watch over a contractor and his help. I have work to do too and cannot devote the time to standing there measuring every thing to see if it is square, nailed right, lined up right. I have had 4 pole type buildings put up and I should have just taken time off from work and baby sit them. #1 building was a 32x34. After paying them, I was putting some siding on it, and noticed the truss spacing didn't look right. Checked it out 3" out of square. #2 building a 52x84. Didn't put shingles on right. Tacks were put in at a angle (not flush) within a year I had holes every where. #3 building 32x40, trusses not set level, 3" bow in 40 ft. Then on #4 building 50x80. Some one told me if you want a building put up right use Amish. I located a Amish contractor that specialized in pole type buildings. My only really request was that all the holes for the siding and roof be drilled on the ground before panels were set up. My other buildings have a droopy, sagging chalk line in places, with the nails in a bow. He said no problem. They measured and drilled about 6 sheets at a time. After building was completed, about a year later I noticed some of the screws coming out. Got up on a ladder and found they had just barely caught the 2x4, right on the edge and some places missed it. On the roof they used 1" screws and the all keep working loose. Should have used longer screws, and completely missed the 2x4 in a few places.. Tried to call them and phone disconnected. Plus I had specified a 12' door height and allow for 6" of concrete floor. They measured from ground to top of door and did not allow for 6" of floor.
