Our Customers Love Our Work!

After looking at pre-fab sheds, I had Jim price the job. Told him what I wanted, he did a terrific job. Square building, top to bottom. On time, for price quoted. A month later he did a rebuild for my mom. I would recommend him to anyone. It is nice to get your money's worth these days.
Jim McMahon (owner) met with us and provided a detailed estimate (along with suggestions) and references. We compared his quote to other providers and found him to be very competitive for the quality of materials (much higher quality than Lowes/Home Depot)…
