Job Stories From Greenwich, CT
WaterGuard and TripleSafe in Greenwich, CT

This Greenwich, CT home had a water issue in the basement every time it rained. The homeowner wanted a solution that would provide his home to have a clean, dry basement. After hearing reputable reviews from others, he decided to contact the experts at Connecticut Basement Systems. 

On the day of the appointment, Sales Representative Steve Machnicz arrived at the home to inspect the basement. He noticed that there was a lot of ground water seepage coming through the area and instantly knew of solution. Upon further inspection, he realized that the basement was allowing a lot of unwanted air and moisture through the rim joists which was causing a humid and sticky basement. In this environment, mold can thrive. Steve went over all the problematic areas and went over in great detail the solution. He proposed a WaterGuard System paired with a TripleSafe sump pump to collect water and discharge it before it enters the basement. Steve also recommended Rim Joist insulation to prevent any unwanted air into the basement and a SaniDry Sedona to keep humidity below 55%. This is exactly what the homeowner had wanted and decided to move forward with the project.

On the day of production, Foreman Krzys Wilk and his team installed each product professionally and efficiently. The overall result was that the basement was dry from any water and moisture and the air quality was improved dramatically. This is exactly what the homeowner had wanted and was pleased with the transformation. 

WaterGuard System in Greenwich, CT

This Greenwich basement had a constant water issue that frustrated the homeowners greatly. Not only was the basement wet, but with the moisture and odor that were results of a wet basement, the area was unhealthy. Wanting a solution, the homeowners decided to call the experts at Connecticut Basement Systems. 

On the day of the appointment, Sales Representative Jason Wood arrived at the home and inspected the basement. He noticed that water and air moisture was entering from the walls and floors. To solve this problem, Jason recommended CleanSpace liner which is a moisture barrier to prevent water and moisture from entering the basement. To waterproof the basement, Jason recommended a full perimeter WaterGuard system which will collect the water internally. Once collected, the water is channeled to the sump pump where it is discharged away from the home. In order to make the basement have more welcoming, EverLast windows and a SunHouse could be installed to ensure the most natural light all year long. The homeowner was very excited with all these products and wanted to move forward with the project.

Water Seepage into Basement in Greenwich, CT

Water seepage into Mike A's Greenwich, Connecticut basement was causing a mold problem and Mike got on the Internet and searched for "seepage causing mold."  He was in luck and filled out a contact form on BasementSystems.com.

On October 26th system design specialist Joe Pascarella came out to Mike's Greenwich home and performed a thorough inspection and measurement of the basement.  He then went over the cause of the problem -- water entering the basement through the floor-wall joint -- and a solution -- the installation of our WaterGuard drainage channel system that would drain to a SuperSump sump pump system.  They also decided on the installation of the SaniDry dehumidifier and air filter system, to really create a dry, usable basement space.

In addition to the waterproofing and dehumidification system, Connecticut Basement Systems also sprayed Mold X to neutralize the existing mold. 

Leaking Wall Cracks in Greenwich Home

When Brian G. called us out to his Greenwich home he had concerns with water leaks around his Electrical conduit, a pipe penetration through the foundation wall, and other slight cracks beneath.  Brian had used Connecticut Basement Systems before when we waterproofed a new building of his. 

In this case we injected polyurethane around the pipe penetration through the thickness of the wall and then put our patented FlexiSpan wall crack repair system over the wall cracks and drained this beneath the basement floor. Problem solved.

Sump Pump Upgrades Include a Battery Backup pump in Greenwich, CT

Joe Pascarella helped Ken B. to upgrade his SuperSump system that had been installed by us a few years ago to add the UltraSump Battery Backup Pumping System.  

In all cases, one of our SuperSumps can be upgraded with a battery backup pump for those events where the power goes out, the pump gets unplugged, or the SuperSump doesn't turn on for any reason.  And as a waterproofing company since 1987, we know that most basement get wet after a waterproofing systems has been installed because of a pump failure.
