Job Stories From Hamden, CT
Livable Basement Finishing in Hamden, CT

A homeowner in Hamden, CT was looking to have their basement finished and turned into a livable space. They called our Total Basement Finishing team of Connecticut Basement Systems to schedule an appointment with us. One of our Sales Consultants, Cary Benjamin, went out to the home to meet with the customer to understand their wants and needs. They wanted new floors, walls, a full bath, and more to make their basement a live-in space. Once a plan was developed, it would be time for our crew to come in. 

One of our Foremen, Sheldon Lennon, and his team would take on this large project. They installed our EverLast walls that protect them from any moisture. They also installed our Elite Plank flooring in light pecan, which looks great paired with our EverLast walls. They painted the ceilings black to give it a sleek, industrial look. Our plumber Todd Nihill installed a full bath and our electrician added new lighting and outlets. Overall, this space had a gorgeous upgrade. There is now a full kitchen and full bath in this space, as well as a closed bedroom. This customer was thrilled with the results and this basement is now a perfect place for someone to live!

Waterproofing in Hamden, CT.

Lori received one of our mailers to her Hamden home and contacted us for some waterproofing needs in her basement. A wet basement can have a musty odor or even cause health issues due to mold growth. Not to mention it is not unusable space, if it is damp and wet. 

Our crew started by digging a trench through the concrete floor to lay down WaterGuard for the perimeter of the basement and set up a discharge line through the foundation wall to drain out and away from the house. Then we installed the TripleSafe Sump Pump system to keep the basement dry and usable. 

WaterGuard and TripleSafe Sump Pump in Hamden, CT

This Hamden home had a water problem in the basement that could not be ignored. The homeowner wanted a dry, healthy basement all year long to improve the efficiency of his home. He decided to contact Connecticut Basement Systems after hearing reputable reviews to help find him the perfect solution.

On the day of the appointment, Salesman Brad Glazer arrived at the home to inspect the basement. He noticed that water was seeping into the area, causing the area to become wet every time it rained. Brad recommended that the best solution for this basement would be to install a WaterGuard System paired with a TripleSafe sump pump. The WaterGuard system will collect the water internally and channel it to the TripleSafe sump pump. The TripleSafe sump pump is our most reliable sump pump because it provides three levels of protection to ensure that the basement stays dry. It also includes a battery backup system in case of a tripped circuit or power outage. This was exactly what the homeowner wanted and decided to go through with the project.

On the day of production, Foreman Krzys Wilk and his team installed the WaterGuard System and TripleSafe sump pump professionally and efficiently. The job only took a day to install and they left the basement in pristine condition. The homeowner was very pleased with the work done and now enjoys his clean, dry basement. 

BrightWall in Hamden, CT

This Hamden, CT home was experiencing a moisture issue that greatly affected the walls of her basement. Not only were they discolored from water seepage but it gave the basement a dreary and unwelcoming vibe that deterred the homeowner from wanting to go to the basement. Wanting a solution, she decided to call the experts at Connecticut Basement Systems.

On the day of the appointment, Sales Representative Brad Glazer arrived at the home to inspect the basement and propose a solution. The walls were definitely damaged due to water seepage and he knew that BrightWall best solution. BrightWall is rigid plastic sheeting that's attached to your basement wall by drilled-in plastic fasteners. Its bright white color maximizes the available light in your basement, creating a cheerful, clean-looking space. This product is also 100% waterproof and washable, and it creates a vapor barrier on your basement walls to block out water vapor and humidity. This is exactly what the homeowner had wanted and was thrilled that there was a solution for her basement wall problem.

On the day of production, Foreman Krzys Wilk and his team installed this product efficiently and professionally. Once completed, the basement was transformed and the homeowner was ecstatic with the BrightWall product. Not only did it look great in the area, but now she can go into the basement with a peace of mind that the walls will not be damaged by water moisture in the future!
