How do I file a warranty claim?

Contact us at (408) 441-1114 or email sales@baystonedepot.com with your original purchase receipt, photos of the issue, and a description of the concern. Our team will review your claim within 2-3 business days.

Does the warranty transfer if I sell my home?

Our material quality guarantee stays with the product regardless of ownership changes. For engineered stone manufacturer warranties, transferability varies by brand.

What if I notice a defect after installation?

If you notice a material defect that was not visible during slab selection, contact us immediately with photos and documentation. We will assess whether the defect existed at the time of sale.

Do I need to seal my stone to maintain the warranty?

While sealing is not a condition of our material warranty, we strongly recommend regular sealing for natural stone surfaces as part of proper care.

What is the claim process for engineered stone brands?

For engineered quartz brands (Caesarstone, Silestone, Cambria, etc.), warranty claims go through the manufacturer. We handle the claim submission on your behalf and coordinate directly with the manufacturer until resolution.
