Frequently Asked Questions

1. How do I start the process?

Final location and accessibility to your property are important considerations when delivering and installing our fully pre-assembled sheds. A site assessment from HPM, a structural mover, or contractor is the first step in determining if your property is a feasible location for our pre-built sheds. We recommend finding an experienced and licensed professional to help with the delivery and installation. Please complete the form below to have our team contact you for more information.
