I spent $800 on one of those resin shed kits from a big box store thinking it would be a quick weekend project. Turns out the walls warped after one hot summer and the floor buckled by fall. Should have just built a simple wood frame myself for half the cost. Anyone else had a plastic shed fall apart on them?
Honestly who cares about grammar when we're talking about sagging issues? @robinp89 did yours get worse after the first winter or did it just happen all at once?
