We had our whole house installed by fdw, 4 weeks after installed they warped and popped up. We contacted fdw and got the run around, the owner was very confrontational, said we had slab leak, and about 10 other excuses. We payed to have someone come out and confirm no slab leak. It was a 3 year nightmare- we had to get an attorney, and we payed wood specialist to come out and confirm that they never scrapped the glue off the concrete before laying the floors. Never do it again, we tell everyone to stay away!
