Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Great Neck property, gives you a straight answer, and fixes it right the first time.
Licensed & insured in NY · Real warranties
Halo Water Proofing is a NY-licensed Waterproofing company that treats every Great Neck job like it's the only one on the schedule.
Every Great Neck 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 Great Neck 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 Great Neck technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Great Neck homeowners.
Odor is often the very first clue Great Neck homeowners notice, well before any water is visible.
Small cracks in a Great Neck foundation rarely stay small — seasonal ground movement tends to widen them over time.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
No two Great Neck basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Great Neck emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →Not every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
Ask About Crack Repair →Already have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
Book a Pump Check →Some Great Neck properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →Older Great Neck 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 Great Neck commercial projects around business hours or tenant schedules so operations keep running.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
We figure out fast whether this needs an emergency dispatch or a scheduled inspection.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
No verbal number that quietly grows once the truck pulls up — the written quote is the final word.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.
We've heard every Great Neck horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
There's no verbal quote that grows once the crew shows up — the written estimate is final.
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 Great Neck property later.
If your Great Neck basement just needs a small crack seal instead of a full system, that's exactly what we'll tell you.
We can supply the documentation most carriers ask for before approving a Great Neck claim.
Our trucks are recognizable around Great Neck — we don't cut corners on jobs our neighbors will see.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"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."
"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."
"First contractor who actually explained where the water was coming from instead of just quoting a number."

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 Great Neck contract we sign.
