Why Diefenderfer Plumbing?

Leak Detection


If you suspect you may have a leak under slab the first thing to do is remain calm. Most slab leaks can be rerouted with minimal additional repairs. Rerouting avoids the destruction of concrete slabs and gets the water back on as quickly as possible. 

Service Calls


Whether old or new, your house will eventually need service. Is your water heater leaking? Faucet Dripping? Drain line clogged? Feel confident to call a company that was built on word of mouth and we will treat you like family.
