"I posted an initial review on 2/21/19 on a job done on 1/11/19 to fix groundwater from coming into our basement. The drainage system and sump they installed was not collecting all the water that was coming in, as we had leaking from several areas along an uneven rock ledge. I had reached out to our salesperson by phone and email and never heard back, so I was very frustrated. About 3 weeks after I posted the review, I did get a call from Jeff Allen, one of the supervisors. To make a long story short, he sent out one of their waterproofing specialists to look at the problem. We had already hired an independent mason to try to remedy the problem but he had not yet had a chance to do the job. Jeff convinced me that CT Basement systems would do absolutely whatever it took to fix my water problem. I cancelled the independent mason. Danny, a mason from CT Basement Systems came out and used a very ingenious method to divert all the water to the originally installed water guard trough and then to the sump. It is working beautifully!! I think Danny is a genius and I am so impressed and thankful for Jeff's perseverance and kindness in making this happen. I am now a very happy customer."

"Nick helped me with a ground based solar project. He dug an electrical trench and laid the conduit. The town inspected and signed off on his work. Great communication, fair price, and precise execution of the work."

"He was on time, friendly, and honest. We had a plumber tell us that the pipe was broken at the septic tank so Phil and Mike came out to dig it up and replace it. When he dug it up he found that the pipe was not broken and was totally honest about it and gave us options and help that solved our issue we were having. I would totally use him again for any work I need done in the future."

"Our property has a low spot, and when it rains it creates a huge puddle (pond!) on one side of the driveway. Because we will be doing some driveway work, we needed to remedy this situation first. Using both Angie?s List and other sources, we obtained estimates, many of which were quite high and the proposals seemed to be overkill for our situation. We contacted AJ (M&M Construction) and he responded quickly to meet with us to discuss the project. We had sent him pictures of the issue after a rain so he could better understand the problem. He listened to our concerns, discussed options and give us his best solution and sent us a proposal the next day.
Based on our meeting with all the contractors, we decided to accept AJ?s proposal. He was very knowledgeable, professional and willing to listen to what we had to say (which other contractors were not...one contractor came without pen or paper, asking us for some, even called his office several times asking how to use the equipment to measure the job!!). AJ stayed in touch concerning the scheduling of the work. The job needed to be coordinated with the driveway job and AJ worked with the contactor to ensure the drain would be placed appropriately. That saved us a lot of phone calls between contractors and left us feeling confident there would be no issues between the two jobs.
The crew arrived on time, got right to work and worked to get the job done in one day. AJ and his crew worked very well together. During the digging of the trench for the drain pipes, they ran into a huge buried tree stump that must have been left during the house construction. AJ offered to remove the stump, rather than work around it, noting that, as the stump rots it might cause sagging of the new driveway. He gave us a fair price to remove it and after some effort, he removed it and dragged it away. Even with that disruption, the job was completed in one day and completely to our satisfaction. After the drain and drain pipes were installed, they raked out the area, leveled it and left it ready for the driveway contractor. They even reseeded the area that was affected by the dragging of the stump.
We have had a number of construction projects done at our home and often we never saw the supervisor or person in charge on the job. But AJ was there from the beginning to the completion of the project. To us, that is important. If there is an issue, we know it will be addressed immediately.
As another client said in their review, I would not waste any time with other contactors. M&M Construction did the job from the beginning estimate to completion (and them some!), exceeding our expectations. Before leaving, AJ made sure we knew to call him if there were any issues so he can come out to remedy them. Thanks to AJ and his crew for a great job. You can be sure that we will use them again and will definitely recommend them.
