Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Mount Sinai property, gives you a straight answer, and fixes it right the first time.
Licensed & insured in NY · 24/7 dispatch
Halo Water Proofing started small in the Mount Sinai area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Our Mount Sinai 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 Mount Sinai 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 Mount Sinai 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 Mount Sinai crews hear about most.
Odor is often the very first clue Mount Sinai 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.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
These upstairs clues usually show up months after the basement moisture problem actually started.
No two Mount Sinai basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Mount Sinai emergency line busy — active flooding always jumps ahead of routine inspections in the queue.

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 Mount Sinai 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.
A local dispatch model means the technician who answers your questions is the same one who shows up.

Every Mount Sinai 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."
"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."
"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."
"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."
Every Mount Sinai technician we send is background-checked and trained on the systems we install, so the crew that inspects your property is the same one that fixes it.
