Values are indicative and may vary slightly.
Free shipping anywhere in the lower 48, on your schedule. Your order arrives flat-packed on a pallet by freight carrier. The carrier calls ahead to schedule a delivery window and drops the pallet at the curb. You just need somewhere a truck can pull up.
At delivery. Every part is labeled and pre-drilled at the factory: check the pallet with the driver before you sign, and everything is ready for assembly. Step-by-step instructions walk you through it. Most of our customers build with two people, over a weekend.
Covered for 10 years. Every greenhouse is backed by a 10-year warranty against defects under normal use. If something fails, email us and we make it right.
Real support, from a real person. Not a form that goes nowhere: email us at support@greenlyhouse.com, Monday to Friday, and a person reads it and answers the same business day. A question halfway through assembly? We stay reachable.
Something wrong at delivery? A missing part, a panel damaged in transit? Note it on the delivery slip and email us a photo: we ship the replacement part at no charge. And if the delivery itself goes wrong, you are covered (see our refund policy). Not sure which size fits your yard? Email us BEFORE you order, and we will help you get it right the first time.
Standard shipping is free for eligible Greenlyhouse orders delivered within our US service area.
Your estimated delivery window appears directly below the Add to Cart button and updates automatically based on the date of your order.
Once your order has been prepared and handed to the carrier, you will receive tracking information by email.
Greenhouses are large products, so delivery arrangements may vary depending on the order and destination. Any important delivery instructions will be communicated before arrival.
Delivery dates are estimates, not guarantees. Carrier availability, weather or other circumstances can occasionally affect the schedule.
