Man, my experience with Warners is very different. They gave our countertop guys the wrong dimensions for a built in stove. Ended up having to have the granite countertops recut. Wouldn’t have been a big deal but Warners dug their heals in and didn’t want to pay for the counters to be recut. We eventually worked it out but they wouldn’t own up to their mistake so I’ll never work with them again.
Sounds like our experience was an exception but it was a big one.
