Free curbside freight delivery
Choose your size, color and options. Your greenhouse ships from the manufacturer's warehouse, packed for freight.
We'll contact you to set up a delivery time frame that works for you.
Delivery is by LTL motor freight on an 18-wheeler. Let us know about tight roads or low wires so we can plan ahead.
Someone needs to be there to receive the delivery. The driver does most of the work but may need a hand.
Foundations and bases are bulky, so we recommend ordering them together with your greenhouse to avoid a separate freight charge.
