Licensed & insured in NY · 24/7 dispatch
Halo Water Proofing is a NY-licensed Sump Pump Installation company that treats every Harriman job like it's the only one on the schedule.
Every Harriman technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
Our Harriman 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.
📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Harriman homeowners.
A musty smell usually means moisture is already moving through your Harriman basement, even if the floor looks bone dry.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
Efflorescence is a reliable early sign that water is moving through your Harriman foundation wall right now.
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.
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.
A flooded Harriman basement doesn't wait for morning, and neither do we. Our crews get it out and start drying the space the same visit.
Get Emergency Help →We seal active Harriman foundation cracks with hydraulic cement injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across Harriman after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
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 →We handle below-grade waterproofing for Harriman property managers and business owners, scheduled around your operating hours to limit disruption.
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 Harriman property before anyone drives out.
A Harriman technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
Every Harriman 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 Harriman 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 Harriman, 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.
Our technicians are trained to diagnose accurately, not to upsell — that changes the advice you actually get.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Word of mouth is still how most Harriman customers find us, which keeps our standards high.
"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."
"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."
We back our Harriman work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
