"They called back immediately from my initial message. They came first thing in the morning and by noon my new water heater was installed and up and running. They went over and beyond what I have ever experienced with other plumbing technicians.They explained everything up front and I found them to be highly knowledgeable. I would highly recommend this company and they have acquired a new lifelong customer based on their performance dealing with my situation."

"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."

"A soft wall due to improperly installed gutter by some other entity or homeowner caused water to constantly leak into the wall from the exterior roofline. This soft wall grow moldy and become riddled with pests/bugs. The contractor identified the potential issues, agreed to explore and open the walls and discuss the conditions, made sound recommendations for repair and did exactly what was noted in the repair (replaced a load bearing exterior wall, fixed the sill plate, completed the roof, shingles etc. and closed up the walls on the inside with insulation and sheet rock.). The work was timely, well done, the workers were clean as they did the job and kept the rest of the property clean. The manager of the job David Apel was and is an excellent communicator with phone/email/text and photos of processes and progress. I am going to use this company in my own investment endeavors on other properties and projects given the level of finished work, the timing and especially the level of detailed communication."

Sump Pump Installation questions, answered by experts

If you notice any new sump pump noises, such as persistent clanging or gurgling, then you likely have a sump pump problem on your hands. Foul odors coming from the pump can also indicate problems. Additionally, if your unit turns on but doesn't pump water, you might have to address electrical problems. In any of these cases, it's a good idea to hire a professional to address the issue.

A sump pump battery backup can typically run for 6 to 24 hours. The factors that affect its runtime include the battery capacity and pump usage. 

When purchasing your backup system, take these factors into consideration to determine which system is best for your home. If you live in an area with frequent and long-lasting power outages, consider a longer-lasting backup battery.

The difference between an ejector pump and a sump pump lies in their purpose and design—an ejector pump functions to remove liquid gray water and soft solid sewage waste from your home. If you have a laundry room or bathroom in your basement, an ejector pump for your sewage tank prevents sewage from backing up in your washing machine or bathroom’s drains.

A sump pump is designed to remove excess groundwater that may enter your home, either due to flooding or periods of heavy rain.

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.
