I did not choose Walt. My partner, who has hired Walt for several commercial plumbing matters, recommend him to me. If I had done my usual three references/estimates, no matter how good the price I would not have chosen Walt. He has no people skills, speaks what I can only call Waltslish and carries on endless monologues. Fortunately, he does not seem to need an audience. To be honest he gives me a bit of the willies. And he came to my home on his schedule, not mine. He fit my job in between others of higher priority - to him BUT if you are concerned first and foremost about knowledge, quality and price (I don't think any plumber in the area can compete with his prices) then Walt's is an excellent choice.
