Halo Water Proofing has been the trusted call for Exterior Waterproofing across Merrick because we answer the phone, show up when we say, and stand behind the work.
Licensed & insured in NY · Real warranties
Halo Water Proofing is a NY-licensed Exterior Waterproofing company that treats every Merrick job like it's the only one on the schedule.
We don't run a bidding war between crews. The Merrick technician who inspects your property is the same one who does the repair, start to finish.
Our Merrick 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.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Merrick crews hear about most.
A musty smell usually means moisture is already moving through your Merrick basement, even if the floor looks bone dry.
Small cracks in a Merrick foundation rarely stay small — seasonal ground movement tends to widen them over time.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A pump under constant strain tends to fail during the exact storm that needs it most.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Merrick schedule.
These upstairs clues usually show up months after the basement moisture problem actually started.
Whatever's going on with your Merrick property, chances are we've already fixed something similar nearby this month.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help →Not every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
Ask About Crack Repair →Already have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
Book a Pump Check →Some Merrick properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →Older Merrick homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.
Get a Crawl Space Quote →We handle below-grade waterproofing for Merrick property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote →Here's exactly what Merrick 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.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
The number you approve is the number you're billed — no change orders once the crew shows up.
You get documentation of the work plus a real warranty — not just a handshake.
Plenty of companies advertise Exterior Waterproofing in Merrick — here's what actually separates the ones worth calling from the ones that aren't.
There's no verbal quote that grows once the crew shows up — the written estimate is final.
We're not routing your call through a national center — the person who answers is close by.
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 Merrick customer with an honest fix than push a system you don't need.
We can supply the documentation most carriers ask for before approving a Merrick claim.
Our trucks are recognizable around Merrick — we don't cut corners on jobs our neighbors will see.
