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 redid 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.

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.

We are in the planning stages of adding a two car garage onto our existing garage, and turning the existing garage into a family type room. We get some water seepage in the garage and in the basement (on the opposite side of the wall of the garage). We would like to eliminate the chance of any water getting into the new room.

I would like to know if I could go to my dad's house and give an estimate of what it would cost to fix the basement. ** I can not receive calls, please leave a text message and I will gladly answer.
Vicinity of Glen Avenue in Norwalk
My father in law's home is on Glen Avenue in Norwalk. He gets water in his basement when it rains. He has looked at grading and a new drainage pipe and both were quite expensive. I suggested he also consider a sump pump in his garage to remove the water once it come in. There is nothing of value in his basement except his furnace and hot water heater. Water has come up to within two inches of units where damage could be done to them and his worries he'd need a new furnace. Interested in a ball park price for sump pump installation - create hole in cement garage floor, install cylindar and pump and waste water removal, which would be up about 5 feet to drain into back yard area
