Licensed & insured in NY · 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.
Talk to a real Uniondale technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Uniondale crews hear about most.
Odor is often the very first clue Uniondale homeowners notice, well before any water is visible.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
Efflorescence is a reliable early sign that water is moving through your Uniondale foundation wall right now.
A pump under constant strain tends to fail during the exact storm that needs it most.
This is one sign we tell Uniondale customers never to wait on — wall movement tends to progress, not resolve on its own.
Peeling paint near the floor upstairs is one of the last signs Uniondale homeowners connect to a basement problem.
No two Uniondale basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Uniondale basement doesn't wait for morning, and neither do we. Our crews extract it fast and start drying the space the same visit.
Get Emergency Help →Seasonal ground movement in Uniondale tends to widen existing cracks over time, so sealing early usually costs less than waiting.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across Uniondale after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check →Some Uniondale properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →Older Uniondale homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.
Get a Crawl Space Quote →We can phase larger Uniondale commercial projects around business hours or tenant schedules so operations keep running.

A real technician asks the right questions to understand what's likely happening at your Uniondale property before anyone drives out.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
Every Uniondale quote is written before work starts, not estimated verbally and adjusted later.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.
We've heard every Uniondale horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts — what you approve is what you're billed.
A local dispatch model means the technician who answers your questions is the same one who shows up.
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.
We can supply the documentation most carriers ask for before approving a Uniondale claim.
Every Uniondale job reflects on the next referral, so we treat each one like it matters.
"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."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"Straightforward commercial quote, professional crew, no back and forth."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
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.
