Basement Waterproofing That Saved a Home
Michael from Queens
Michael bought a 100-year-old home in Queens. During heavy rain, his basement flooded repeatedly. Mold started growing, and he was afraid of losing his new investment.
“I searched for Waterproofing Contractors in New York and found your team. You showed up fast and knew exactly what was wrong.”
What we did:
- Installed a perimeter French drain system
- Applied interior waterproof wall coatings
- Set up a powerful sump pump with a backup battery
- Added a dehumidifier and sealed foundation cracks
After one storm, Michael called again—not to complain, but to thank us:
“My basement stayed 100% dry. No leaks, no mold, no mess. You saved my house.”
