"Gregg and his team were on time, extremely professional, neat, all of the above! The quality of the job done is 100% effective. I had Hydro-static pressure and water coming in through my basement floors every time it rained, Gregg analyzed everything in a matter of seconds, gave me an absolute fair price, best in the industry, gave me a commercial quality job at my residence and even took care of relative issues that I had in my basement concerning the garage area, the level of the floor, and an old sump pump. I would absolutely recommend Gregg Segnit and Contractor's Waterproofing, Corp. for anyone's water proofing needs. He has been in this profession for years and knows what he is doing. He stuck by his word to everything he said, and actually left my basement in better shape than it was before, outside of waterproofing. Since him and his team completed the job I have not seen one ounce of water in the basement. Not one drop. Before then, every time it rained outside I would get water coming into my basement from all angles, the wall and floor. He installed in my opinion the perfect interior drain system for my home, at a reasonable price, and with a lifetime guarantee, I cannot be happier as a homeowner. I will never go to anyone else for my waterproofing needs. Thanks again Gregg and team"

"I cannot say enough good things about this company. A power outage at our house over a weekend caused a lot of damage to various motors throughout the house. Joe called very quickly after I left a message (on a Sunday!) and went through a lot of possible things to check in order to try to save my paying for a service call (much appreciated). Ended up scheduling an appointment for 8 a.m. the next morning. He was here on the dot and quickly diagnosed the problem. Fixed not only that, but helped my husband get other things restarted as well (water filter and hot water heater) before he left. The best experience ever with a service professional -- I'd highly recommend him and Old Faithful anyone with well or well pump problems."

"Very quick communication and fantastic customer service. Connected with Entoni for a water heater replacement. He went above and beyond to track one down. Ended up having to go to NJ to get it! They uncovered some additional issues during the install and had to come back the next day to do the job right. Transparent through the entire process. Very fair price for the work. Would recommend!"

"I really liked CT Basement systems. The sales rep walked me through the process of the basement SaniDry I had installed. When the installer came it turned out that I didn’t need all of the duct work and I was able to save a few hundred bucks. The installer was very professional, neat and helpful . I definitely will hire this company again. Customer service even followed up with me a few days later and had to remind me to register the system (good thing because I had forgotten)."

"They arrived promptly. They were able to assess, quickly quote and then replace our water heater all within a couple hours of the initial call. Not only that, the job was done professionally and they even cleaned up afterward. Couldn’t ask for a better experience."

"

Our shower was dripping.  We had called another plumber, who said he couldn't get to us until July.  My husband called Atomic Rooter from work.  They came to our house that evening, and completed the job in less than an hour.  They arrived on time and were courteous and professional.  The plumber had the part with him and was able to install it quickly without having to turn off the water in the house.  They accepted our credit card.  We would definitely use them again.

Sump Pump Installation questions, answered by experts

One common reason a sump pump stops working is improper sizing. Different locations need different sizes and power ratings of sump pumps depending on the typical amount of water the pump needs to manage. If your sump pump is too small for the quantity of water, it can overwork and either burn out or reduce the life of the unit. If the pump is too big, it can overwork and burn out early. 

A sump pump should be placed at least three feet deep in a pit. The rim of the sump pump basin should be level with your basement floor. If you find your pit is too deep, you can fill the bottom with gravel until the rim of the sump pump is flush with the floor.

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.

Start by calling a plumber if you want to install a sump pump battery backup. Talk to them about your situation and needs. Sometimes, electricians or waterproofing contractors will install a battery backup, and in that case, the plumber you call should be able to point you in the right direction.

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.
