Frequently Asked Questions (FAQs)

1. What is the most durable type of shed?

Vinyl sheds tend to be more durable. Vinyl sheds do not crack easily and are more weather resistant. They can usually withstand extreme temperatures better than other plastic sheds. This is a great choice for those who live in hot and humid climates.

2. Is it cheaper to buy a shed or have one built?

If you've been wondering is it cheaper to build your own shed, you'll discover that yes, it is less expensive to build your own shed than to purchase a pre-built shed. That is at least if you have all the tools required to build the shed. Typically, it won't take many specialty tools to build the shed.

3. Are resin or metal sheds better?

Metal sheds are more durable as they are fire, insect, rot, and weather resistant. They can rust, but they are more durable to the elements vs. wood. Resin is the most durable because it's weather-resistant to fading, rusting, warping, rotting, insects, and fire.

4. Do metal sheds have floors?

Let's start with the prepared base. Many metal sheds do not come with a floor as they are bolted to the ground so you need to make sure you have a level base. This would normally be flagstones, or concrete but not tarmac which can get very hot in the summer allowing the anchoring bolts to pull loose.
