One thing I will say about Suncast is that their customer service is excellent
That doesn’t suprise me at all. Their products hold up great and I look to them first when buying something they might sell. I have a 6ft tall garbage can shed that’s made by Rubbermaid. It was warped by the sun within 2 years. I still have it but the doors haven’t opened right since. I also bought a full shed from Rubbermaid figuring it would be better some years later. Same problems. Warped and discolored quickly. I have 7 year old Suncast boxes that are a little faded, but still 100% perfect otherwise, exposed to the same sunshine.
