Here's What Our Customers Are Saying:


"I made the Right Decision Choosing your Firm !"

I want to thank you and your crew for doing such a great job installing French Drains in my basement last week. I am thrilled that I finally have that project behind me and I know I made the right decision choosing your firm. Your men worked diligently every hour they were there. They were able to complete the work in just two days, which was amazing in itself. Also they cleaned up any mess that was made in the process of completing the work including hauling off the cement remnants and most improtantly they did a beautiful job of installing the sump pump and checked to be sure it was in good running order. You are a man who knows his work well and for that I am thankful. In addition you presented a fair and reasonable price for the job...

Sincerely, Mrs. Joanmarie Blessington

"The world needs more companies like the Dennis Diffley & Sons Inc. "

My company experienced a major problem with our sewer line out of the plant. Dryvit Systems called several companies for solutions including Dennis Diffley & Sons Inc.. We were told the problem called for digging up 160 feet of drain line, except Dennis Diffley. Dennis explained they could relieve our problem without digging, for a lot less money with their state of the art equipment, and have us up and running in a couple of hours. Diffley was hired for the job. In came a team o f people (pure team work at its best) to repair our problem (that we had been told by others could not be done) and to my satisfaction and happiness, Dennis Diffley had my plant up and operational, on it's own within 4 hours, only 30 minutes to repair, the rest was for clean up. The world needs more companies like the Dennis Diffley Company, honest, reasonable and true team of work. I would highly recommend your company to anyone who needs drain service or repair.

I thank you for all your help in our time of need,

"I would not hesitate to call them again !"

I contacted Dennis diffley Drain Company because of a flooding problem I was having on my property. A crew of workers arrived and discussed the problem with me of what they felt had to be done to eliminate the problem.

They installed an underground drain system that I was very peased with. I would not hesitate to call them again, if needed, or recommend their company to anyone. I feel their company would be an asset to any community

Sincerely yours,

"Not a Drop of Water in my Basement "

...During the severe rain and thunderstorms a couple of weeks ago, I was in CT. I listened to the radio all the way home, and listening to all the talk of damage and flooding, I was anxious to get home to see if I had any water in my cellar. NOT A DROP!

It's the first time in 26 years I've owned the property that I haven't had water in my cellar. Thanks to the wonderful job you did back in January...

Thanks, Lou Calande

"He has gone above and beyond to help me "

I'm so lucky that I found Dennis Diffley Services several months ago: I met Dennis by chance, by calling him to get an estimate for one of my client's who is trying to buy a forclosed propert that needed a new water line. Dennis has gone above and beyond to help me in resolving this issue. Since this first meeting, I've called him again for other potential jobs. I would definitely recommend him and his company without any reservations.
