This Norwalk home had continuous water problems in their basement. The only line of defense the home had was an old sump pump in a hole. The homeowners decided to call the experts at Connecticut Basement Systems and our Certified Basement Water proofer Matt diagnosed and fixed the issue. We came in and installed our Waterguard drain system. The Waterguard is put in the ground but above the footing or “mud zone” to prevent any clogs.

The water flowing through the drain system makes a trip through our premier sump pump system the TripleSafe. The TripleSafe sump pump has a total of three pumps for that added security. The first pump which sits the lowest starts pumping first. The second pump will start running if the first pump is unable to handle the amount of water coming in. The third and final pump will start running if the power goes out or is tripped, because it is backed up by a battery.

As a finishing touch we installed our CleanSpace Vapor Barrier. The vapor barrier is a 100% waterproof plastic material that's perfect for unfinished basement walls. With a 25-year warranty [PDF] for wear and tear, it's durable, washable, and has anti-microbial protection called UltraFresh built right in! The homeowners can sit back and know that their basement won’t have anymore moisture or water issues.

In this basement we installed our Waterguard drainage system. We also upgraded the existing TrenchDrain in addition to installing a SuperSump pump. On the outside of the house we put in an Iceguard to prevent water back up during winter months from frozen pipes.

To stop water from flowing through the doorway of this home, our team installed the TrenchDrain grated draining system along the edge of the entranceway. TrenchDrain resembles half of a basement drainage pipe, with a grated opening fitted snugly on top. The grate is flush or slightly below the floor, eliminating any tripping hazard. After the cement finishes drying, the owners of this home can be confident that no water will leak through their doorway any more.

Vicinity of West Rocks Road in Norwalk
Found water in basement lots of it - water is still coming in after cleanup. House is 3.5 years old has not happened in the past. No sump pump but there are cracks on the floor - one specific area has water seeping in. Temporary sump pump set up and it's removing the water as it comes into the basement. Need someone to come out ASAP
Vicinity of Maher Dr in Norwalk
Last year we had three massive rainstorms that resulted in a flooded basement (had to replace carpet, etc.). We are thinking of possibly moving in next year and cannot have potential floods coming in when the rain gets bad.
Vicinity of Pheasant Ln in Norwalk
Sometimes I get water in my basement, although I already have sump pumps that run a lot during this time of year.
Vicinity of Glendenning Street in Norwalk
The previous homeowners built a deck (c. ~1995) and extended the kitchen onto the deck footings, which have since subsided. About three feet of our kitchen now slants down about an inch, and the door to the deck is slightly out of true. I suspect that there are some flashing/water infiltration issues as well. We would like to preserve as much of the kitchen as possible while building a proper foundation underneath the space. Also, we will be replacing the deck once the foundation / floor issue is fixed. Looking to get quotes on the cost and approaches for this project.

The previous owners put up a temporary support post in the basement that needs to become a permanent one. I think that more support posts are needed around the stairwell area to prevent additional floor sagging/uneven floors.
