Background-checked Mount Sinai technicians · Written pricing
Halo Water Proofing is a NY-licensed Exterior Waterproofing company that treats every Mount Sinai job like it's the only one on the schedule.
Every Mount Sinai technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
Our Mount Sinai crew leads carry years of hands-on repair experience, not just sales training — which is why the advice you get on-site tends to match what actually needs fixing.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Most Mount Sinai calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
A musty smell usually means moisture is already moving through your Mount Sinai basement, even if the floor looks bone dry.

Get Emergency Help →Seasonal ground movement in Mount Sinai tends to widen existing cracks over time, so sealing early usually costs less than waiting.

Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
