Background-checked Merrick technicians · Written pricing
Halo Water Proofing is a NY-licensed Waterproofing company that treats every Merrick job like it's the only one on the schedule.
Our Merrick crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
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.
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.
Odor is often the very first clue Merrick homeowners notice, well before any water is visible.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
Efflorescence is a reliable early sign that water is moving through your Merrick foundation wall right now.
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.
Peeling paint near the floor upstairs is one of the last signs Merrick homeowners connect to a basement problem.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Merrick crews handle most.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.

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.

"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."
