Had a shed built in 2017. I paid an extra $120 to level the shed. Two years later, and it is now un-level. Looked on their website and saw they provide leveling services for a nominal fee, and that's perfectly fine. Contacted the sales guy who I dealt with during the shed purchase. He never contacted me back (over a week now). I then contacted the company through their website to request their leveling service. They too haven't got back to me. Guess they don't think the request is worth their time. Be very careful doing business with TuffShed. If you need any after sales service, you will not get it.
