Before we waterproofed this West Haven basement, the moisture seeping through the walls and flooring made the cement look terrible and threatened the value of the home. We installed a TripleSafe sump pump, our most reliable sump pump with 2 pumps and a backup battery in case of power outage. Additionally, we put CleanSpace on the walls, which stops any water vapor from getting into the space. With our innovative products, we transformed this basement into a clean, dry space that's a great asset to this home.

BrightWall is a rigid plastic sheeting that's attached to your basement wall by drilled-in plastic fasteners. It's durable, washable, and will not support the growth of mold or rot. BrightWall redirects any water that passes through your basement wall to a sump pump system.

Job Stories From West Haven, CT
Basement Waterproofing in West Haven, CT

A homeowner in West Haven, CT was dealing with water issues in their basement. They called us at Connecticut Basement Systems and after scheduling an appointment, we sent out one of our Sales Consultants, Jeff Wade, to diagnose the problems. He informed this customer that they would need to completely waterproof their basement. Our foreman, Krzysztof Wilk, and his crew got to work and began the installation. They installed a WaterGuard and a TrenchDrain system that would collect any water and properly drain it to the sump pump. The specific sump pump this homeowner needed was our TripleSafe which is our most reliable. It will pump the water away from the home at a safe distance. Our crew also installed CleanSpace walls that will protect them from any water vapor. This home is now water free and this customer is thrilled with the results!

Service Maintenance in West Haven, CT

This West Haven, CT home has our sump pump system but the homeowner noticed water in her basement. She immediately called Connecticut Basement Systems to have a Service Technician come out to find what was causing her wet basement. 

Sam the Service Technician arrived at the home to assess the situation and looked into the system. He opened it up and instantly knew what the problem was, the system was clogged  due to iron build up. Sam was able to clear out all the buildup and ensure that every part of the system was working correctly. 

How do we prevent iron build up in our systems? We highly recommend having an annual maintenance done to the system to prevent any type of buildup. The last time this system had a maintenance was back in 2014 and that was the cause of the buildup. This is why we always highly recommend an annual maintenance because it is the best way to keep your basement waterproofed! 

WaterGuard System and ThermalDry Flooring in West Haven, CT

This West Haven home had a wet basement that was causing the area to be unwelcoming to enter. The homeowner wanted to find a solution to solve his wet basement and to make the area finished for all to enjoy. After doing much research, he decided to contact the experts at Connecticut Basement Systems.

On the day of the appointment, Sales Representative James Stablein arrived at the home to evaluate the basement. He concluded that a full perimeter WaterGuard pair with at TripleSafe sump pump would need to be installed to keep the basement dry. Since the bottom of the basement walls had clear moisture damage, James recommended to have a restoration wall. To ensure that the floors would be waterproofed and appealing, ThermalDry carpet was suggested. The homeowner reviewed each product intensively with James and decided to move forward with the project.

On the day of production, Foreman Krzys and his crew installed the WaterGuard system. This system is installed below the ground around the perimeter of the basement. The purpose is for the system to collect water before it even enters the basement. Once the system collects the water, it is channeled to the TripleSafe sump pump where the water is discharged away from the home. This system will keep the basement dry. In addition to the WaterGuard system, half wall restoration replaced the moisture damaged walls. This was installed by Foreman Kevon Barnett and he also installed ThermalDry Charcoal carpet to finish the basement. The homeowner loved the transformation of his basement and can now enjoy a dry, comfortable basement! 

TripleSafe Sump Pump in West Haven, CT

This West Haven basement had water vapor seeping through the walls and the floors. The homeowners wanted a solution to solve their problems. They decided to give Connecticut Basement Systems a call to set an appointment.

The day of the appointment, our System Design Specialist, Glen Knafel arrived at the home to give a free home evaluation. After evaluating the basement, he concluded that a sump pump would be needed in order to keep the water out of the basement. After reviewing all the options with the homeowners, they decided to purchase and install a TripleSafe Sump Pump. 

When it came to the installation date, Krzysztof Wilk and his production crew came to the home and began the process. They located the perfect spot to install the TripleSafe Sump Pump. The TripleSafe Sump Pump is unique because it has 3 pumps that will ensure maximum protection. The first pump handles everyday water that might want to enter the basement. If the first pump fails or there is more water than normal, the second pump will turn on. Lastly, if there is a power outage in the house, the third pump will activate since it is charged by a battery, protecting your home in the most chaotic times. 

With the TripleSafe Sump Pump, these West Haven homeowners can now enjoy a dry basement all year around, thanks to Connecticut Basement Systems!

Water in basement from heavy rain
Project Location: West Haven, CT
Would like to get an estimate on fixing some minor flooding in a portion of our basement to prevent larger issues down the road. No visable cracks but water seems to come up through the floor at the cracks where the floor and walls meet forming small pools <1/8' in depth and no larger than 3 feet in diameter in extremely heavy rainfalls.

I live on a hill and water tends to enter in the basement on once side only. We've tried to cover the cracks on the foundation but not working entirely. This happens only when we get heavy rain for days which is 1-2 times a year in our area. This round of rain there was no water coming in but the floor tiles have lifted so water is coming from underneath or somewhere else. We would like some advice on what we can do to stop this to avoid any water, humidity, or potential mold damage. Thank you in advance!
