Exclusions:

 

The warranty does NOT cover the following components, for which replacement parts may be provided at a reasonable cost:

 

• Tempered glass glazing
• Operating parts (such as pistons in automatic window openers)
• Other accessories provided with the greenhouse which are breakable in ordinary use.

 

The warranty does NOT cover damage resulting from any of the following:

 

• Excessive loads placed on the packed product and/or parts
• Glazing breakage caused by large hail, rocks or other projectiles (including rocks thrown by a lawnmower)
• Use of force, incorrect handling, or inappropriate use, neglectful use or assembly or maintenance, commercial use or use other than for personal or household purposes

• Extreme storms, wind, flood, fire, overaccumulation of snow load, or other extreme weather conditions.

 

Snow Load Advisory:

 

Customers are expected to regularly clear snow accumulation from the roof of their greenhouse as overaccumulation may crush the structure.  This type of damage is not covered under this warranty.

 

Commencement and Transferability

 

This warranty commences from the date of purchase and is non-transferable. A dated proof-of-purchase must be presented upon request. Customers are advised to keep this product warranty and proof of purchase in a secure place as they will be needed to process any claims.

 

 

 

Claims Process:

 

Address your claim to the customer service department by phone or email. A photograph or sample of the defective part(s) may be required to expedite the resolution process. If needed, the customer will allow the manufacturer or its representative to access and/or examine the greenhouse and its parts at the original service location.

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.
