Background-checked Smithtown technicians · Written pricing
Halo Water Proofing is a NY-licensed Emergency Waterproofing company that treats every Smithtown job like it's the only one on the schedule.
We don't run a bidding war between crews. The Smithtown technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Smithtown 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.

Odor is often the very first clue Smithtown 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.
This is one sign we tell Smithtown customers never to wait on — wall movement tends to progress, not resolve on its own.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Smithtown crews handle most.
A flooded Smithtown basement doesn't wait for morning, and neither do we. Our crews extract it fast and start drying the space the same visit.
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 →A failed sump pump is the top reason for emergency calls across Smithtown after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.

We quote the job in writing after seeing it in person, so there's no surprise on the final invoice.
We're not routing your call through a national center — the person who answers is close by.

"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."
"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."
"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."
