Licensed & insured in NY · 24/7 dispatch
Halo Water Proofing is a NY-licensed Sump Pump Installation company that treats every Northport job like it's the only one on the schedule.
Every Northport 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 Northport 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 Northport 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 Northport crews hear about most.
Odor is often the very first clue Northport homeowners notice, well before any water is visible.
Small cracks in a Northport 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.
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.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
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.
Get Emergency Help →We seal active Northport foundation cracks with hydraulic cement injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Most Northport 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 →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 Northport 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.
A real technician asks the right questions to understand what's likely happening at your Northport property before anyone drives out.
No jargon, no pressure — just a clear look at what's actually going on.
Every Northport quote is written before work starts, not estimated verbally and adjusted later.
You get documentation of the work plus a real warranty — not just a handshake.
We've heard every Northport 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.
Our crews stage locally near Northport, which is why most emergency calls get a technician on-site in under two hours.
If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.
If your Northport basement just needs a small crack seal instead of a full system, that's exactly what we'll tell you.
Filing a claim can be confusing — we've walked Northport customers through this process many times.
Our trucks are recognizable around Northport — we don't cut corners on jobs our neighbors will see.
"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."
"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."

Every Northport 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.
