We had a completely broken faucet and fully expected to have to buy a new one. The plumbers from German arrived right on time and were able to fix the faucet in about 20 minutes. Super nice guys. Very efficient and professional. Excellent…

Needed an estimate, called German, they came out and looked at the service I needed then left. I haven’t heard anything back about it, this was 2 weeks ago. I will never call them again!!
