From a hairline crack to a fully soaked crawl space, our Sewell crew has seen it and fixed it. No guesswork, no scare tactics โ just a clear plan and a fair price.
Licensed & insured in NJ ยท Real warranties
Halo Water Proofing is a NJ-licensed Foundation Crack Repair company that treats every Sewell job like it's the only one on the schedule.
We don't run a bidding war between crews. The Sewell technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Sewell 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 โ not a vague callback promise.
๐ +1-866-476-1348Most Sewell calls didn't start with a flood โ they started with one of these small signs weeks or months earlier.
A musty smell usually means moisture is already moving through your Sewell basement, even if the floor looks bone dry.
Stair-step cracking in block foundations is one of the most common early signs our Sewell crews see.
Efflorescence is a reliable early sign that water is moving through your Sewell foundation wall right now.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
No two Sewell basements are the same โ soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Sewell 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 โNot every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
Ask About Crack Repair โA failed sump pump is the top reason for emergency calls across Sewell after heavy rain โ we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check โFor yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options โA damp Sewell crawl space drives up humidity throughout the house โ we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote โWe can phase larger Sewell commercial projects around business hours or tenant schedules so operations keep running.
Request a Commercial Quote โHere's exactly what Sewell customers can expect from first call to final walkthrough.
We figure out fast whether this needs an emergency dispatch or a scheduled inspection.
A Sewell technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
The number you approve is the number you're billed โ no change orders once the crew shows up.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every Sewell horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
We quote the job in writing after seeing it in person, so there's no surprise on the final invoice.
A local dispatch model means the technician who answers your questions is the same one who shows up.
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 โ that changes the advice you actually get.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Every Sewell 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."
"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."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
Every Sewell technician we send is background-checked and trained on the systems we install, so the crew that inspects your property is the same one that fixes it.
