Halo Water Proofing has been the Oyster Bay area's go-to call for 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 Oyster Bay 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 Oyster Bay 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.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Most Oyster Bay customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.

Standing water in your basement doesn't wait for business hours, and neither do we. Our Oyster Bay emergency crews pump out the basement first, then diagnose the source so it doesn't happen again next storm.
