Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Leonia property, gives you a straight answer, and fixes it right the first time.
Free, no-obligation estimates · Real warranties
Halo Water Proofing is a NJ-licensed Basement Waterproofing company that treats every Leonia job like it's the only one on the schedule.
We don't run a bidding war between crews. The Leonia technician who inspects your property is the same one who does the repair, start to finish.
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.
📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Leonia homeowners.
A musty smell usually means moisture is already moving through your Leonia basement, even if the floor looks bone dry.
Stair-step cracking in block foundations is one of the most common early signs our Leonia crews see.
Efflorescence is a reliable early sign that water is moving through your Leonia foundation wall right now.
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 Leonia schedule.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Leonia crews handle most.
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 →We seal active Leonia foundation cracks with polyurethane 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 →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
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 →We can phase larger Leonia commercial projects around business hours or tenant schedules so operations keep running.
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.
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 Leonia 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.
We'd rather earn a repeat Leonia customer with an honest fix than push a system you don't need.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Every Leonia job reflects on the next referral, so we treat each one like it matters.
"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."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"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 Leonia work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
