I've been a customer with DME Expansion Joints since '77 or 78'. They occasionally build expansion joints for us, and they buy a lot from us, as well. For a company that's always busy, they are very service-oriented and easy to get in touch with.
I know the owners of DME, the dad who used to run things, and the kids who run it now. They are a very well-run business. They are executing for service, and that's the name of the game.
