"They ran interior piping to a sump pit. They had to break up the floor install the piping. Install a sump pump pit so the water was pumped outside. Then recement the trench. This is the second time I have used this company and I highly recommend them. I have had two different crews doing the work and both did an outstanding job."

"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."

"John responded and visited quickly. His crew completed the project over the course of a few days. It looks quite good and has already successfully withstood a heavy rainstorm. It clocked in at more $$ than I was expecting, but I'm 74 and don't really know what things are supposed to cost anymore! I'm sure it will outlast me."

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.

"it was great, Kris and his team were great to work with, they came in and got the job done quickly and professionally, they cleaned up every day before they left. If it wasn't for his team our basement would've flooded multiple times a year. We feel like we got our basement back, doubling the size of our living space in the house"

"I purchased an deal for $99 for 2 hours of labor.  Originally I intended to apply the time toward replacement of a shower faucet, but the same week, three gate valves in my basement began to fail.  Lew was very responsive and able to accommodate my schedule, and replaced all three valves with ball valves as well as the piping in the area.  I purchased an additional $150 worth of parts from Lew which are warrantied for a year.
What I appreciated most was Lew's evaluation of the shower faucet, which he looked at while he was at my house.  He pointed out that the faucet that I had purchased would not meet my long-term needs and made recommendations so that I could purchase (on my own) a model that would be better for me.  He also gave a very rough quote for the labor that would be required.  Lew could have just installed the faucet I purchased and waited until it failed in another year and installed another one and made twice as much money, but he didn't.  I'll certainly have him back again.

Drain Pipe Installation questions, answered by experts

For disposal clogs with standing water, use a sink plunger and place it over the garbage disposal drain. Push the sink plunger up and down the drain about six to eight times before lifting. If the sink drains, the clogged food particles are dislodged from the drain. If there’s still standing water, repeat the steps until the standing water clears out. 

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

Avoid flushing non-degradable items, schedule regular inspections, and address minor clogs promptly.

While technically possible, it is unlikely that a clogged toilet will fix itself. Clogs caused by water-soluble materials like toilet paper or human waste may eventually break down in the water, allowing flow to resume. However, this can take time, and any clogs from solid objects require manual removal. In most scenarios, especially if you don't have another bathroom, it is best to fix the clog yourself or call a plumber.

Your dishwasher drain hose may have a clog if your dishwasher is full of water, your dishes aren’t getting cleaned, or water takes a long time to discharge into the garbage disposal.
