Job Stories From Windham County, CT
Annual Service on SumpPump in Woodstock, CT

We have had this individual from Woodstock, CT as a customer since 2015. She has annual maintenance done to their SuperSump just to ensure proper function and in hopes to quickly catch any issues that may arise. We are proud to report there were not any hiccups and the unit is in great working order!

We originally installed WaterGuard, Trenchdrain, a SuperSump, and an IceGuard to waterproof the basement.

Garage Floor Crack Repair in Putnam, MA

This Putnam, MA homeowner called us with concerns about a crack in her garage floor that seemed to get worse each year, especially around wintertime. She noticed issues with the trim work around the garage doors due to the slab rising up. We sent out a System Design Specialist who concluded that our PolyLevel Injection Foam would be a great fix for this situation.

Our PolyLevel is a 2-part expanding foam that is guaranteed to stabilize the foundation and lift the slab. We are pleased to have been able to help this customer with her cracked garage floor. She will no longer need to worry about the rising slab causing trouble!

Basement Waterproofing in Grosvenordal, MA

This customer in Grosvenordal, MA reached out to us with concerns for the wet basement. Our System Design Specialist met with the homeowner and evaluated the space to identify the perfect solution. 

Our team installed 17 feet of WaterGuard sub-floor perimeter drainage, 2 inspection ports, a SuperSump, an IceGuard and a LawnScape outlet where the drainage goes. 

Dry Basement in Woodstock Valley, CT

      When this customer called our appointment center, she requested to have a Systems Design Expert come out to her home to formulate a solution for her wet basement woes. The inspector thoroughly looked at the home, basement and foundation for any issues of mold, water, humidity or instability. He then came up with the perfect solution, individualized to this customer's needs. 

   Our production crew installed a TripleSafe pump to remove water from the basement and discharge it from the home. This included installing WaterGuard, a WaterGuard Port, IceGuard and a LawnScape Outlet. 

Waterproofing in Thompson, CT

When this individual called, they reported having standing water in their basement with heavy moisture and odors in the air. We sent a System Design Specialist out to the home to offer the customer proven solutions to their problems. 


The customer ultimately had 30 feet of WaterGuard installed in their basement, which directed water towards their SuperSump Plus. Then the water was pumped through the discharge line and out into the yard via the LawnScape Outlet. A SaniDry dehumidifier was also installed and tied into the sump system so water from the machine would drain from the home and not need to be emptied. 


The homeowner was very satisfied when our crew left their drier, healthier home. 

CleanSpace in North Grosvenordale, CT

When this customer called they stated that they had a dirty crawlspace that needed to be encapsulated. We sent out a Systems Design Specialist to formulate a plan to help the homeowner.

Our company installed 500 square feet of CleanSpace vapor barrier. They wrapped the piers, removed debris and regraded the floor drainage. A SmartDrain was added to remove water from the space and a SaniDry Sedona dehumidifier was plugged in to omit odors, mold and moisture from the air.
