Licensed & insured in NY · Written pricing
Halo Water Proofing is a NY-licensed Exterior Waterproofing company that treats every Merrick job like it's the only one on the schedule.
Every Merrick technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
We've worked on foundations from decades-old Merrick 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.
Talk to a real Merrick technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +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.
Stair-step cracking in block foundations is one of the most common early signs our Merrick crews see.
Efflorescence is a reliable early sign that water is moving through your Merrick foundation wall right now.
A Merrick sump pump that never rests is usually undersized or nearing the end of its life.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Peeling paint near the floor upstairs is one of the last signs Merrick homeowners connect to a basement problem.
No two Merrick basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Merrick 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 Merrick foundation cracks with epoxy injection — stopping the leak at its source instead of patching the surface.
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 →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial Merrick 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.
You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
A Merrick 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.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every Merrick 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.
We're not routing your call through a national center — the person who answers is close by.
Warranty terms are explained in plain language before you sign, with no fine-print surprises later.
Our technicians are trained to diagnose accurately, not to upsell — that changes the advice you actually get.
Filing a claim can be confusing — we've walked Merrick customers through this process many times.
Word of mouth is still how most Merrick customers find us, which keeps our standards high.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Straightforward commercial quote, professional crew, no back and forth."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"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 Merrick work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
