Rachael was very professional and courteous while helping me schedule my appointment. Greg Daru, service plumber, was excellent! He introduced himself as he arrived; very respectful of my property. He was genuine and friendly. He explained everything very thoroughly, in a way that I could understand. He provided equipment manual; dated equipment replaced. Thank you, Greg, for an excellent experience!

I have used Althoff for years because of the quality of their people. I would not use anyone else.

My brother-in-law referred us to Althoff, and I cannot thank him enough for recommending such a group of competent and friendly professionals. I only wish I had learned about Althoff 20 years ago!
