In the after picture you can see from the wet cement that our crew very neatly installed the WaterGuard drainage system to prevent flooding in the future.

Job Stories From Guilford, CT
Crawlspace Waterproofing in Guilford, CT

A homeowner in Guilford had a large crawlspace that was experiencing water issues, so they called us at Connecticut Basement Systems to solve their problems. After scheduling an appointment, one of our Sales Consultants, Vin Orsini, drove out to the home to meet with the customer and estimate the issues. He informed them that they would need CleanSpace, a TripleSafe, and even a SaniDry Sedona in order to waterproof this crawlspace. 
Soon it would be time for our crew to install Vin's proposal. One of our Foremen, Marcial Lopez, and his crew would tackle this installation. They put CleanSpace around the whole perimeter on the floors and walls. This would ensure there will be no more water damage and it will protect it from moisture and mold growth. They also installed a TripleSafe Sump Pump to pump out any water collected away from the home at a safe distance. For extra protection from moisture and mold growth, they installed a SaniDry Sedona Dehumidifier. Now this crawlspace is water-free and the homeowner is happy!

TripleSafe Installation in Guilford, CT

A homeowner in Guilford, CT had water problems in their basement and an already existing sump pump that was not working for them. They decided to call us at Connecticut Basement Systems to solve their problems. One of our Sales Consultants, Tony Van Deusen, went to the home to estimate the issues. He informed them that they would need our TripleSafe sump pump and CleanSpace to ensure their basement is waterproofed. 

Soon it would be time for one of our Foremen, Marcio Bahiense, and his team to take on this project. They installed the TripleSafe which would collect any water and pump it out into the yard at a safe distance. This water would be collected from the WaterGuard system that was installed around the perimeter of the basement. They also installed CleanSpace on the walls to protect them from moisture and mold growth. Our team installed IceGuard so that when the weather gets cold, water will still be pumped out no matter what. This customer is happy with their dry basement!

CleanSpace Encapsulation in Guilford, CT

This Guilford crawlspace was dirty and damp which can create an unhealthy environment.  The dampness in the crawlspace can support mold and moisture damage. These were concerns for the homeowner who wanted to make sure his crawlspace was a healthy environment. He did his research and decided to give Connecticut Basement Systems a call and scheduled an appointment.  

Taz Petersen was the Sales Representative who arrived at the home the day of the appointment. He inspected the crawlspace and explained the different solutions the homeowner had. Once a plan was set, a production date was scheduled and the homeowner was ready to have his crawlspace transformed.  

On the day of production, Garfield Sanderson and his production team began the installation process. A WaterGuard System was first installed to ensure that water would be properly channeled outside of the home. Then, a CleanSpace encapsulation was installed on the floors and walls to prevent any moisture from seeping through. Lastly, a Sanidry Sedona dehumidifier was installed to ensure that the crawlspace will stay dry.

With a dry, clean crawlspace, the home instantly transformed into a healthier environment. The homeowner is extremely happy with his crawlspace thanks to Connecticut Basement Systems!

A finished basement in Guilford, CT needed waterproofing

Martha H of Guilford, CT noticed her finished basement had wet spots in the carpeting. She realized that the wet finishing materials in her basement caused a potential mold problem and new she would have to do something about the situation before it got worse. After searching the web she found Larry Janesky's Connecticut Basement Systems and decided to have them come in for a free estimate to solve the water problem. 

Shortly after giving them a call, an appointment was set for Mike Fuschetto to come evaluate the basement. Mike decided that having Al Guglielmoni install a WaterGuard drainage system and a TripleSafe Sump Pump system would be the best bet to get rid of any water. WaterGuard is a drainage channel that will lead any water coming into the basement to the TripleSafe pump system, where it will be then pumped out of the home a safe distance away.

Michael also proposed the SaniDry Basement Air system for Martha's basement. The SaniDry can dehumidify and filter the air at the same time. It's ENERGY STAR® rating makes it three times more efficient than common hardware store dehumidifiers.

Martha has been very happy and having no issues with water coming into her basement. It's now a dry, moisture free space that is safe to refinish and enjoy for years to come.

We have a 2.5 story house on Leetes island with a crawlspace accessible only from the outside of the home. It covers the entire footprint of the structure (no porches/decks). It has less than 24 inch clearance from joist to dirt. It is currently muddy from all of the recent moisture. A solid wood floor lies above and is starting to cup. It most likely needs new foam sealer on the joists and some water mitigation on the ground. Thank you.
