Halo Water Proofing has been the Smithtown area's go-to call for Interior Drainage System 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.

We don't send apprentices to figure it out on your dime. Every Smithtown job is run by a technician who has done this exact repair dozens of times, with a supervisor who signs off before we call it finished.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.
📞 +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.

If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.

When your Smithtown basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew around the clock, pull the water, and start drying the space with commercial-grade equipment the same visit.
