We sent in dimensions and shelfing instructions via email and fax and phone. We did changed our minds about some of the shelfing sizes during the process but Jack was very accommodating with our changes and requests. Two workers were sent out on the date agreed upon (usually a week backlog according to Jack) and they built our shed to our specifications for size, shelfing, vents, window and door the same day. We requested painting but had to wait for a few days for the paint team to arrive and paint the shed. We were more than happy with the shed. The crew did clean up after themselves but due to the fact that lumber was sawed on the site, we still had a lot of sawdust in the side yard and the front yard remaining. We will definitely use Quality Sheds again.
