Before and After Pictures from Southport
Super Sump Pump in Southport, CT

Super Sump Pump in Southport, CT

Before After
Super Sump Pump in Southport, CT Super Sump Pump in Southport, CT

This Southport, CT basement had water issues that frequently frustrated the homeowner. The water that would enter the basement left a musty odor, making the area unwelcoming. The homeowner wanted a solution to solve this water issue and decided to call Connecticut Basement Systems.  

The solution for this basement was to install a WaterGuard system paired with a Super Sump pump. The WaterGuard system is a below the floor drainage system that collects water before entering the basement internally and channeling it to the sump pump. We installed our SuperSump pump to collect the water from WaterGuard system and channel it away from the basement. The SuperSump pump has a powerful Zoeller 1/3 horsepower cast-iron sump pump, capable of pumping 2,200 gallons of water! This was the perfect waterproofing solution for this home and the area now stays dry all year long. With no water entering the basement, the musty odor had diminished and the homeowner could not be happier!

In this Southport, CT basement, there had been previous issues with the home's sump pump as well as there being a very outdated dehumidifier that was not performing nearly as well as other dehumidifers nowadays. Once the homeowner's realized these 2 problems, they decided to make a call to Connecticut Basement Systems with regards to having these two machines replaced.

Once CBS received the call, we quickly were able to bring over our newest sump pump and SaniDry dehumidifier. All that needed to be done was the installation which our team was able to do in a very timely fashion. With these two issues fixed, the homeowners had a much more reliable system in their basement and they were very gratfeul for the quick and professional work we did for them.
