"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."

Drain Pipe Installation questions, answered by experts

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.

If your drain doesn’t have metal crosshairs or crossbars, you should use a tub drain extractor. These tools create a grip on the drain so you can turn it using a 1/2-inch ratchet drive, drain key, or wrench. Your drain may not have crosshairs if it's old and broken.

Professional tools include drain snakes, hydro jets, cameras for line inspection, and enzymatic or chemical cleaners for dissolution.

Water leaking through your basement floor is a good sign of a clogged drain, but another sign of a clogged basement floor drain can include unpleasant odors coming from the drain. Also, hearing gurgling noises when water drains from the basement or having other plumbing fixtures (like toilets or other drains) backing up is a good indicator.

You can unclog a double kitchen sink by plunging the side with the garbage disposal. Cover the drain hole on the other side first to avoid creating a mess. Plunge up and down until the water starts to drain. You can also pour in baking soda and vinegar to try and dissolve a clog.
