Licensed & insured in NY · 24/7 dispatch
Halo Water Proofing is a NY-licensed Foundation Crack Repair company that treats every Uniondale job like it's the only one on the schedule.
Our Uniondale crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
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.
📞 +1-866-476-1348Water 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.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Uniondale schedule.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
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 get it out and start drying the space the same visit.
Get Emergency Help →We seal active Uniondale foundation cracks with epoxy injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Most Uniondale pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
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 →Musty smell upstairs with no obvious source? Check the crawl space first — it's usually the culprit.
Get a Crawl Space Quote →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial Uniondale jobs with written specs and a real timeline.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
No jargon, no pressure — just a clear look at what's actually going on.
The number you approve is the number you're billed — no change orders once the crew shows up.
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.
We're not routing your call through a national center — the person who answers is close by.
Our major repairs come with written, transferable warranties — useful if you sell the Uniondale property later.
We'd rather earn a repeat Uniondale customer with an honest fix than push a system you don't need.
Filing a claim can be confusing — we've walked Uniondale customers through this process many times.
Every Uniondale job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"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."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
We back our Uniondale work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
