Halo Water Proofing has been the Greenlawn area's go-to call for Interior Drainage System because we answer the phone, show up on time, and stand behind the work.
We're Halo Water Proofing — a NY-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Greenlawn-area foundations, and exactly how to stop it.
Every technician on our Greenlawn crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Greenlawn technicians hear about most often before an inspection.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
Stair-step cracks in block foundations are a common early warning sign we see across Greenlawn-area homes.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Greenlawn storm.
This is one sign we tell Greenlawn customers not to wait on — wall movement tends to progress rather than resolve on its own.
Flooring that's cupping or warping near an exterior wall is a common clue our Greenlawn crews trace back to a drainage issue.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Greenlawn every day.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Greenlawn emergency crews remove the water first, then diagnose the source so it doesn't happen again next storm.
Call for Emergency Service →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our Greenlawn crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Greenlawn lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →For Greenlawn properties fighting grading or drainage issues, an exterior French drain can intercept water before it ever reaches the foundation wall at all. We map your yard's slope and water flow before recommending which approach fits.
Ask About Drain Systems →Older Greenlawn homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
Get a Crawl Space Quote →We work directly with Greenlawn property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Greenlawn crews follow on every job.
We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
You receive a written, itemized quote before any work begins — the number you approve is the number you're billed.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
We quote the job in writing after inspecting it in person, so what you agree to on the phone or at your door is what shows up on the final invoice.
Because we're actually based near Greenlawn rather than routing calls through a national center, we can usually get someone out the same day you call.
Warranty terms are explained before you sign, in plain language, so there's no fine print surprise if you ever need to use it.
If your Greenlawn basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
We can supply the photo documentation and repair scope most Greenlawn, NY carriers ask for before approving a claim.
Our name is on trucks driving around Greenlawn every day — we don't cut corners on a job our neighbors will see.

"Straightforward commercial quote, no back-and-forth, crew was professional the whole project."
