Warranty
GK Calls Limited Lifetime Warranty
GK Calls stands behind the craftsmanship of every call we build. Each call carries a Limited Lifetime Warranty against manufacturer defects and issues caused by faulty workmanship or materials. If your call has a defect we caused, we'll repair or replace it.
What's Covered
- Manufacturer defects in materials or workmanship
- Issues caused by a fault in the product itself
What's Not Covered
- Wood splitting or cracking. Wood is a natural material, and splitting can occur for several reasons outside our control — including climate, temperature swings, and humidity. This is a natural occurrence and is not covered under warranty.
- Lost calls or lost parts. We cannot warranty or replace any call, barrel, insert, or component that has been lost. To help prevent this, we strongly recommend double-looping your lanyard on any call that does not use an O-ring system to keep all pieces secure.
- Normal wear and tear, misuse, or damage caused by improper care or modification.
How to File a Warranty Claim
If you believe your call has a manufacturer defect, please contact us with your order information and a description of the issue. We'll review your claim and, if it qualifies, repair or replace your call. Photos of the issue help us process your claim faster.
