"Thank You" from a very satisfied customer.  R.C. Mastic


    I would like to take this opportunity to sincerely thank you for the way you conduct your business. Of all the companies I have had to deal with in constructing my new home yours has been by far the most reputable...any recommendation I can ever make toward your company will be made with the utmost praise.

L. & C. A


    Thank you for excellent and very prompt service. Your men worked well and late through a thunderstorm to get our water supply functioning and were very pleasant and helpful as well.

We are impressed with your company - G. H. Southampton


   We always complain about people and service..in this instance your entire staff was a pleasure to deal with.

Thank you. P. C. Patchogue



    Thank you for the excellent job your firm accomplished on replacing our well pump. In my eyes there is no PhD from any University that can compare to years of experiences.

    I would be happy to be considered as a reference for your firm if future  State, County, or Municipal jobs warrant.

Sincerely, D. P Town of East Hampton - Department of Sanitation

   I am reading your letters from satisfied customers and would like to agree with all of them.

    Your representative was most knowledgeable, expert and skillful in the diagnosis and the precise Rx for my water problem. I could not be more pleased with his good judgment and obvious experience in water and well matters. In an age of galloping mediocrity, it is nice to know that there are still craftsmen who know their craft.

Thank you,  B. P. K.

    Just a word of thanks for reinvigorating my faith in business people. When we had problems with our pump and water tank (due to a power outage) you responded quickly and efficiently even though you knew it was all under warranty. Thanks so much for being honest and true.

Sincerely, A. L. Southampton
