From a hairline crack to a fully soaked crawl space, our Uniondale crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.
Background-checked Uniondale technicians · 24/7 dispatch
We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
Every Uniondale technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
We've worked on foundations from decades-old Uniondale homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Most Uniondale 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 Uniondale basement, even if the floor looks bone dry.

We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
The number you approve is the number you're billed — no change orders once the crew shows up.
You get documentation of the work plus a real warranty — not just a handshake.
We've heard every Uniondale horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
We quote the job in writing after seeing it in person, so there's no surprise on the final invoice.
Our crews stage locally near Uniondale, which is why most emergency calls get a technician on-site in under two hours.
Warranty terms are explained in plain language before you sign, with no fine-print surprises later.
Our technicians are trained to diagnose accurately, not to upsell — that changes the advice you actually get.
Filing a claim can be confusing — we've walked Uniondale customers through this process many times.
Word of mouth is still how most Uniondale customers find us, which keeps our standards high.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
If a covered repair doesn't hold up, we come back and make it right — no arguing, no extra invoice. That's written into every Uniondale contract we sign.
