Refund Policy
If your products are damaged or defective, please take photos and send them to support@homehaq.com within 30 days, and we will coordinate with the manufacturer to resolve the issue. Customers will not be subject to any costs for damaged/defective returns.
As for non-damaged/defective returns, we accept returns up to 30 days of the item being delivered on most products (for example, made-to-order items cannot be returned). Customers are responsible for shipping costs associated with the return, as well as a restocking fee on some products up to 25% of the purchase price. If you would like to make a return after the 30-day period, it may be accepted on a case-by-case basis.
Cancellations are accepted only for back-ordered products. Generally orders will ship from the manufacturer very quickly, so we cannot process cancellations.
