Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Greenlawn property, gives you a straight answer, and fixes it right the first time.
Licensed & insured in NY · 24/7 dispatch
We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
Every Greenlawn technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
Our Greenlawn 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.
📞 +1-866-476-1348Most Greenlawn calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
A musty smell usually means moisture is already moving through your Greenlawn basement, even if the floor looks bone dry.
Stair-step cracking in block foundations is one of the most common early signs our Greenlawn crews see.
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.
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.
No two Greenlawn basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Greenlawn 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 →We seal active Greenlawn foundation cracks with epoxy 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 Greenlawn 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 →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial Greenlawn jobs with written specs and a real timeline.

We figure out fast whether this needs an emergency dispatch or a scheduled inspection.
A Greenlawn technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
The number you approve is the number you're billed — no change orders once the crew shows up.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.
We've heard every Greenlawn horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts — what you approve is what you're billed.
A local dispatch model means the technician who answers your questions is the same one who shows up.
If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.
We'd rather earn a repeat Greenlawn customer with an honest fix than push a system you don't need.
Filing a claim can be confusing — we've walked Greenlawn customers through this process many times.
Every Greenlawn job reflects on the next referral, so we treat each one like it matters.
"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."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"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 Greenlawn work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
