"I felt the need to write this review, although technically Greg and I have never done business. In the recent round of rain storms, my sump pump stopped working as it is supposed to, and I ended up with about 5 inches of groundwater in the basement. I was able to get the sump pump working again, but 3 days after it stopped raining, I was still getting a lot of water in the pit. I found a sticker for Contractors Waterfproofing, and figured they might of installed the system for the old owners, so I gave them a call. From the moment he picked up Greg was service oriented and responsive. He asked for my address to look up the job, and when he couldn't find it, he called back within 5 minutes to ask what was going on. I explained the problem, and he immediately told me that was normal for my part of town, and told me I just needed to replace the pump and I would be fine. He offered me a price that was half what his competitors charge, and was willing to explain the whole job in detail."

"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."

Sump Pump Installation questions, answered by experts

If you’re wondering if your home even needs a sump pump, consider whether you’ve struggled with flooding issues in the past. If your house is in a flood-prone area, your yard has poor drainage, or you’ve dealt with any other water problems, then it’s likely well worth it to replace your old sump pump with a new one.

Yes, it’s normal (and beneficial) to have a small amount of water in the bottom of your sump pit. It shows that your system is collecting groundwater, rain, and excess water from around your property—just like it’s supposed to. However, if the sump pit is always full, you might have a leak or a faulty sump pump.

Costs range from $300 to $1,200, depending on the pump type, issue, and installation complexity.

Costs depend on pump type, labor rates, and the extent of repairs or installation needs.

Inspect the pump annually, test the float switch, and clean the discharge line to ensure efficient operation.
