We're Halo Water Proofing — a NY-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Greenville-area foundations, and exactly how to stop it.

📞 +1-866-476-1348Most Greenville customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
Odor is often the first sign Greenville customers notice, well before any visible water shows up.
Stair-step cracks in block foundations are a common early warning sign we see across Greenville-area homes.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
Flooring that's cupping or warping near an exterior wall is a common clue our Greenville crews trace back to a drainage issue.
Every Greenville property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Storm season in Greenville, NY means our emergency line gets busy fast — we triage calls by severity so active flooding at your Greenville address jumps the queue ahead of routine inspections.
