Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Northport property, gives you a straight answer, and fixes it right the first time.
Licensed & insured in NY · Written pricing
Halo Water Proofing started small in the Northport area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Every Northport technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
Our Northport crew leads carry years of hands-on repair experience, not just sales training — which is why the advice you get on-site tends to match what actually needs fixing.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Most Northport calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
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 Northport schedule.
Peeling paint near the floor upstairs is one of the last signs Northport homeowners connect to a basement problem.
No two Northport basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Northport emergency line busy — active flooding always jumps ahead of routine inspections in the queue.

Every Northport 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."
"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."
