Update: I had Hummell Plumbing come to my house to replace four angle stop valves that were probably as old as the house (1980s) and were all stuck open. Ross and Steve called me in advance to notify me they were 15 minutes away, and were extremely courteous upon arrival. They completed the job in approximately 20-25 minutes tops. Ross also gave me some advice regarding a new faucet I am installing. Hummell's price was very fair and the service was good. As I stated in my earlier review in 2015, I will call Hummell again with my next plumbing job.
