Before and After Pictures from Marlborough
DryTrak and Half Wall Restoration in Marlborough, CT

DryTrak and Half Wall Restoration in Marlborough, CT

Before After
DryTrak and Half Wall Restoration in Marlborough, CT DryTrak and Half Wall Restoration in Marlborough, CT

Before, this Marlborough basement had a water issue that would make the finished area unwelcoming with damp carpet and a musty odor. The homeowner wanted her finished basement to be usable and practical. After doing some research, she decided to contact the experts at Connecticut Basement Systems for a permanent solution. 

The solution for this basement was to install DryTrak Baseboard Drain Pipe System. This system was necessary in this basement because it had monolithic flooring. We epoxy the drain pipe directly to the floor, leaving a slight opening along the top to collect water leaking in from the walls. Therefore, the basement is waterproofed without jackhammering! Half wall restoration was also performed to fix the damage that was caused by the water. The homeowner also decided to get rid of the original carpet and install ThermalDry Flooring to give the area a completed look. As you can see in the after photo, the basement was transformed to a dry and more comfortable area which is exactly what the homeowner had wanted!

Before, this Marlborough basement had walls that were porous which allowed for water and air to flow through, making the area uncomfortable. The homeowner wanted a solution that would make the walls more attractive while also preventing air and moisture from flowing through. She contacted the experts at Connecticut Basement Systems to help her find the perfect solution.  

The solution was to install BrightWall, which is a waterproof wall panel that also acts as an effective moisture and vapor barrier. Other benefits include: stain resistantance, easy to clean, and are maintenance free. This is exactly what this Marlborough homeowner needed for her basement walls. The transformation of the before and after photos speaks for itself. Now the homeowner does not have to worry about seepage coming through the walls anymore.

Before, this Marlborough, CT basement had leaky basement walls. As moisture frequently made its way inside the home, it left behind unsightly stains on the walls and floors, and made the home susceptible to mold growth and further water damage. Hoping to protect his home from this problem, he reached out to the experts at Connecticut Basement Systems. Soon after, Sales Representative Glen Knafel arrived to evaluate the basement.

By the time the job was finished our experienced Foreman, Kevon Barnett, had gotten rid of the basement’s unsightly stains and solved its moisture issues. First, he installed WaterGuard, our patented perimeter drainage system, which catches water leaks where they begin and channels them to a sump pump. Then he installed Zen Walls throughout the basement, which prevent air and moisture from flowing into the basement space, and add give the room a clean, finished look. The homeowner was excited with the results, and happy to have a dry, clean basement.

Job Stories From Marlborough, CT
Sump Pump Installation in Marlborough, CT

Timothy called Connecticut Basement Systems after having concerns of potential flooding in his basement. We were happy to come in, and help him protect his home!

Sidney Aviz and his crew installed a SuperSump sump pump, UltraSump III sump pump, and an Ice Guard.  This would protect his basement from future flooding by not allowing the foundation water to continue to seep into her basement. These products work together to create a full proof method that will keep her basement waterproofed for years to come.

Project Location: Marlborough, CT
Just bought a house, they fixed a leak from outside the foundation with a new drain pipe, but they also had to reroute the water treatment and sump pump to a dry well. I haven't even moved in, but the 3 inches of rain causes a huge leak and my basement was entirely flooded with at least 3 inches of water. The sump either failed or never turned on. But the pump itself works fine, and sucked most of the water out. I've purchased a shop vac and sucked up a lot of water, but there are many places for water to hide, plus the walls are pine and i'm afraid there is damage. I'm not sure if i can take out a claim with my insurance company for this since I didn't have any belongings down there yet, but this is supposed to be my office space. I want a backup system if the sump should fail again, i want to make sure there is no mold, i've also put a dehumidifier in there.
