Halo Water Proofing has been the Demarest area's go-to call for Waterproofing because we answer the phone, show up on time, and stand behind the work.

Halo Water Proofing started as a small NJ crew and grew because Demarest customers kept referring us to neighbors — that's still how most of our work comes in today.

We don't send apprentices to figure it out on your dime. Every Demarest job is run by a technician who has done this exact repair dozens of times, with a supervisor who signs off before we call it finished.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Demarest technicians hear about most often before an inspection.
Odor is often the first sign Demarest customers notice, well before any visible water shows up.
Hairline cracks can widen over a Demarest winter's freeze-thaw cycle and become active leak points by spring.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Demarest storm.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Demarest call we prioritize fast.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
Every Demarest property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
When your Demarest basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew immediately, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our Demarest crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →Most sump pump failures we see in Demarest happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →For Demarest properties fighting grading or drainage issues, an exterior French drain can intercept water before it ever reaches the foundation wall at all. We map your yard's slope and water flow before recommending which approach fits.
Ask About Drain Systems →A damp, uninsulated crawl space under a Demarest home drives up humidity, invites mold, and wastes energy year-round. We seal it with heavy-duty vapor barrier, address any standing moisture, and can add dehumidification if needed.
Get a Crawl Space Quote →We can phase larger Demarest commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.

"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."

"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
