Frequently asked questions

Lifetime vs Keter sheds — which is better?

Lifetime has the longer warranty (10-year), heavier plastic, and survives California sun better. Keter is easier to assemble.

20+ years with proper installation. 10-year warranty is conservative.

Strongly recommended. Compacted gravel minimum, concrete pad preferred for the larger sizes.
