Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Melville property, gives you a straight answer, and fixes it right the first time.
Licensed & insured in NY · 24/7 dispatch
Halo Water Proofing started small in the Melville area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
We don't run a bidding war between crews. The Melville technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Melville 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.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Melville crews hear about most.
Odor is often the very first clue Melville homeowners notice, well before any water is visible.
Stair-step cracking in block foundations is one of the most common early signs our Melville crews see.
Efflorescence is a reliable early sign that water is moving through your Melville foundation wall right now.
A Melville sump pump that never rests is usually undersized or nearing the end of its life.
This is one sign we tell Melville customers never to wait on — wall movement tends to progress, not resolve on its own.
These upstairs clues usually show up months after the basement moisture problem actually started.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Melville crews handle most.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help →We seal active Melville 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 Melville 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 →A damp Melville 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 Melville jobs with written specs and a real timeline.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
We figure out fast whether this needs an emergency dispatch or a scheduled inspection.
A Melville technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
No verbal number that quietly grows once the truck pulls up — the written quote is the final word.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.

Our trucks are recognizable around Melville — we don't cut corners on jobs our neighbors will see.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."
