Background-checked Great Neck technicians · Real warranties
Halo Water Proofing is a NY-licensed Interior Drainage System 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.
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 Great Neck crews hear about most.
Odor is often the very first clue Great Neck 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.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A pump under constant strain tends to fail during the exact storm that needs it most.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Great Neck schedule.
Peeling paint near the floor upstairs is one of the last signs Great Neck homeowners connect to a basement problem.
Whatever's going on with your Great Neck property, chances are we've already fixed something similar nearby this month.
Storm season keeps our Great Neck emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →Seasonal ground movement in Great Neck tends to widen existing cracks over time, so sealing early usually costs less than waiting.
Ask About Crack Repair →Most Great Neck pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
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.
You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
A Great Neck technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
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 Great Neck 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.
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.
Word of mouth is still how most Great Neck customers find us, which keeps our standards high.
"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."
"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."
"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 Great Neck contract we sign.
