Free, no-obligation estimates · Written pricing
Halo Water Proofing is a NY-licensed Emergency Waterproofing company that treats every Greenvale job like it's the only one on the schedule.
We don't run a bidding war between crews. The Greenvale technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Greenvale 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.

If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Stair-step cracking in block foundations is one of the most common early signs our Greenvale crews see.
Efflorescence is a reliable early sign that water is moving through your Greenvale foundation wall right now.
A Greenvale sump pump that never rests is usually undersized or nearing the end of its life.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Greenvale schedule.
Peeling paint near the floor upstairs is one of the last signs Greenvale homeowners connect to a basement problem.
No two Greenvale basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Greenvale 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 →Seasonal ground movement in Greenvale tends to widen existing cracks over time, so sealing early usually costs less than waiting.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across Greenvale after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check →Some Greenvale properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →A damp Greenvale crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial Greenvale jobs with written specs and a real timeline.
Request a Commercial Quote →Here's exactly what Greenvale customers can expect from first call to final walkthrough.
You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
No jargon, no pressure — just a clear look at what's actually going on.
No verbal number that quietly grows once the truck pulls up — the written quote is the final word.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every Greenvale 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.
A local dispatch model means the technician who answers your questions is the same one who shows up.
Our major repairs come with written, transferable warranties — useful if you sell the Greenvale property later.
We'd rather earn a repeat Greenvale customer with an honest fix than push a system you don't need.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Word of mouth is still how most Greenvale customers find us, which keeps our standards high.
