Wet basement? Cracked foundation? A Halo Water Proofing crew can be at your Uniondale property today — upfront pricing, no guesswork, no pressure.

Halo Water Proofing started as a small NY crew and grew because Uniondale customers kept referring us to neighbors — that's still how most of our work comes in today.

Every technician on our Uniondale 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 Uniondale 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 Uniondale 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.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Uniondale storm.
This is one sign we tell Uniondale customers not to wait on — wall movement tends to progress rather than resolve on its own.

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.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Uniondale emergency crews extract standing water first, then diagnose where it's getting in so it doesn't happen again next storm.
Call for Emergency Service →Hairline cracks are how most Uniondale basements start leaking. We use epoxy injection to seal the crack from the inside out, stopping the leak at the source instead of just painting over the symptom.
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.
