Halo Water Proofing is a NJ-licensed Waterproofing company that treats every Leonia job like it's the only one on the schedule.
Our Leonia 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 Leonia 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 Leonia crews hear about most.
Odor is often the very first clue Leonia 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.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A Leonia sump pump that never rests is usually undersized or nearing the end of its life.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Leonia schedule.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
No two Leonia basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Leonia basement doesn't wait for morning, and neither do we. Our crews get it out and start drying the space the same visit.
Get Emergency Help →Seasonal ground movement in Leonia tends to widen existing cracks over time, so sealing early usually costs less than waiting.
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 Leonia properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →A damp Leonia 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 Leonia jobs with written specs and a real timeline.
Request a Commercial Quote →Here's exactly what Leonia customers can expect from first call to final walkthrough.
A real technician asks the right questions to understand what's likely happening at your Leonia property before anyone drives out.
No jargon, no pressure — just a clear look at what's actually going on.
The number you approve is the number you're billed — no change orders once the crew shows up.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.
We've heard every Leonia horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
There's no verbal quote that grows once the crew shows up — the written estimate is final.

If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.
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 Leonia customers through this process many times.
Our trucks are recognizable around Leonia — we don't cut corners on jobs our neighbors will see.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
