Halo Water Proofing is a NY-licensed Exterior Waterproofing company that treats every Harriman job like it's the only one on the schedule.
Our Harriman 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 Harriman 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.
📞 +1-866-476-1348Most Harriman calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
Odor is often the very first clue Harriman homeowners notice, well before any water is visible.
Small cracks in a Harriman 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 Harriman sump pump that never rests is usually undersized or nearing the end of its life.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
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 Harriman crews handle most.
Storm season keeps our Harriman emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →Seasonal ground movement in Harriman tends to widen existing cracks over time, so sealing early usually costs less than waiting.
Ask About Crack Repair →Most Harriman pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check →An interior drain tile system routes water to a sump pump before it reaches your Harriman basement floor at all.
Talk Drainage Options →Musty smell upstairs with no obvious source? Check the crawl space first — it's usually the culprit.

"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
"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."
"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."
