Wholesale Hub Terms: Because materials are custom cut and processed to order, transactions operate under strict final-sale terms with no standard returns, credits, or cancellations. Product coverage is limited strictly to transit damage or manufacturing defects that directly compromise structural integrity:

• Identical Exchanges: Verified structural failures qualify for a 1-for-1 replacement. The original defective material must be returned to our driver at the time of the replacement delivery. Cosmetic variations, sun discoloration, and minor yard weathering do not qualify for claims.
• 24-Hour Window: Claims must be reported with clear photo verification within 24 hours of delivery.
• Drop-Zone Rule: To protect against jobsite handling accidents, verification photos must show the material completely untouched in its original drop-zone location as left by our driver, prior to any movement or installation.
