Refund and Damage Policy

Refund

• We do not provide for or allow for "Buyer's Remorse" 
• We only give full credit for product received in re-sellable condition. It is assumed that no greenhouse arrives back in a re-sellable condition (based on practical experience) at a minimum most if not all packaging has to be replaced - and all to often some parts are damaged - as a result we have a minimum restocking charge of 20% for all our greenhouses - but if product is damaged - cost of damaged parts will be subtracted from the refund

 

Damage

Customers are required to accept delivery of all packages, even if a box arrives damaged. Any visible damage must be noted on the Bill of Lading at the time of delivery and reported to us promptly.

• Small Items (UPS & FedEx Shipments): If an item is damaged, customers should contact us and we will immediately send a replacement part.
• Greenhouses: Customers should take digital photos of any damage (if possible) and email them to us for review. Based on our assessment, we will either:

• • Send replacement parts immediately
  • Suggest an easy repair (minor damage to aluminum greenhouse parts is often fixable with basic tools, like pliers)
  • Offer direct compensation for cosmetic damage (typically $100 for RIGA or Victorian Greenhouses)
  • Fully replace parts with structural damage

We are committed to making sure every customer receives a high-quality product and the support they need for any issues.
