"Inspection of a previously installed sump pump system (primarily the sump pump). Inspection found that it seized up and wouldn't have functioned. Replacement made - and very fortunately - since when the pump is needed, it IS needed. It wouldn't have been good to have a flooded basement or have an upcoming flooded basement."

"Connecticut Basement Systems prides themselves on their superior customer service, and they really live up to that. Their communication, quality of products and service, and attentiveness to customer needs is unsurpassed. Here are a couple of examples of how they go the extra mile for a satisfied customer: They installed their basement drainage system around my existing heating oil tank, but as I'm planning to convert away from oil this summer, they offered to come back AT NO EXTRA CHARGE once the tank is removed, to reroute the drainage system. Also, I was scheduled for a 3-day project, which included the replacement of some flooring in my basement. On the day the project began, we reconsidered the need for the flooring, and asked if we could cancel that portion of the job. They could not have been more accommodating to that adjustment, and made the change with no questions asked or negative attitude, even though it significantly lowered the price of the project and eliminated a whole day of scheduled work on 2-days' notice. That sort of total customer dedication is rare. I recommend them highly."

"They looked at the sump pump and gave me a choice of ways I could solve my problem. They repaired and showed me and explained the repair. They were very neat and cleaned up after. I would recommend them to anyone 👍"

"Easy process from quote to work complete. The crew worked on a few small projects -- fixed a damaged wall, repaired flooring, and installed a new toilet."

"We did some ourselves and we hired another contractor who was so detailed and spent lots of time at the estimate seeing what the actual problem was. He found the problem and proposed a solution which was NOT what M+M suggested or, proposed.

"I was very pleased with my experience with Griswold Plumbing, they installed a new shower faucet/showerhead and later a water treatment system. They were prompt, very professional, and courteous going the extra mile when needed. I highly recommend Griswold Plumbing and won't hesitate to call them again."
