II have known Jim Duffy for many years. If I have any plumbing issues or need to install new fixtures, I would call Jim.

Jim is very professional and knowledgeable.



Jim was quick to respond and fixed our issue. I just moved to the Katonah area from Brooklyn and its comforting to have found a plumber like Jim in the area.



I have known and made use of the Duffy plumbing firm since the 1950s!

Their work has always been prompt, efficient, workmanlike and fairly priced. Jim Duffy, has carried on his father's tradition for excellence and I can fully recommend him to anyone in need of plumbing work!

Work done was swift, accurate, clean and came in on budget!

Mr. Duffy is a first rate craftsman.

A good communicator of what has to be done, then, does it !

Would refer him to friends and relatives for sure !!!

Easy to work with, willing to discuss options.  Estimate for the project was very fair.  Professional and friendly.  Would definitely use them again.

Can't say enough about Jim and team.  They're there when we need them and they always fix it right.



Jim Duffy is an excellent plumber. Returns calls promptly and does quality work.

Do not hesitate to hire him if you have a plumbing or heating job you want done right the first time.



They did an excellent job installing my new oil fired heating system.  They adhered to the schedule and price.  We are very satisfied and highly recommend them others
