Had my greenhouse installed by Derek. Nice guy and very knowledgeable, however, Greenhouse not very sturdy, not even a year and lots parts falling off. I'm assuming it should have been more tightly screwed. Door piece fell off.... contacted Derek and haven't heard back and it's been about a month. At first he was very quick to reply to my questions within a few months of purchasing, But doesn't seem to bother in quick replies to my emails. It's been a year since my purchase.
