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

One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Uniondale technicians hear about most often before an inspection.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Hairline cracks can widen over a Uniondale winter's freeze-thaw cycle and become active leak points by spring.
Efflorescence is a clear sign that water is actively passing through your Uniondale foundation wall, even if you've never seen standing water.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Uniondale lot's water table.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Uniondale call we prioritize fast.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Uniondale every day.
Storm season in Uniondale, NY means our emergency line gets busy fast — we triage calls by severity so active flooding at your Uniondale address jumps the queue ahead of routine inspections.
Call for Emergency Service →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our Uniondale crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →Most sump pump failures we see in Uniondale happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →An interior drain tile system channels water to a sump pump before it ever reaches your Uniondale basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →A damp, uninsulated crawl space under a Uniondale home drives up humidity, invites mold, and wastes energy year-round. We seal it with heavy-duty vapor barrier, address any standing moisture, and can add dehumidification if needed.
Get a Crawl Space Quote →We work directly with Uniondale property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Uniondale crews follow on every job.
