Licensed & insured in NJ · Written pricing
Halo Water Proofing is a NJ-licensed Exterior 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.
Talk to a real Leonia technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Most Leonia calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
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.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
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 extract it fast and start drying the space the same visit.
Get Emergency Help →We seal active Leonia 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 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.
You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
A Leonia 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.
You get documentation of the work plus a real warranty — not just a handshake.
Plenty of companies advertise Exterior Waterproofing in Leonia — here's what actually separates the ones worth calling from the ones that aren't.
You get a real number before any work starts — what you approve is what you're billed.
A local dispatch model means the technician who answers your questions is the same one who shows up.
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 Leonia customers through this process many times.
Word of mouth is still how most Leonia 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."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"Straightforward commercial quote, professional crew, no back and forth."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
We back our Leonia work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
