Halo Water Proofing has been the Smithtown area's go-to call for Exterior Waterproofing because we answer the phone, show up on time, and stand behind the work.
Halo Water Proofing started as a small NY crew and grew because Smithtown customers kept referring us to neighbors — that's still how most of our work comes in today.
Every technician on our Smithtown crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Most Smithtown 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 Smithtown customers notice, well before any visible water shows up.
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Smithtown storm.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Smithtown call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our Smithtown crews trace back to a drainage issue.
Every Smithtown 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 Smithtown, NY means our emergency line gets busy fast — we triage calls by severity so active flooding at your Smithtown address jumps the queue ahead of routine inspections.

Get a Crack Assessment →Already have a sump pump that's failing or too small for your Smithtown lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →Some Smithtown lots need both an interior and exterior system working together — we'll tell you honestly if that's the case rather than selling just one.
