From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Dunellen before. We show up, we diagnose it straight, and we fix it right.
We're Halo Water Proofing — a NJ-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Dunellen-area foundations, and exactly how to stop it.
We don't send apprentices to figure it out on your dime. Every Dunellen 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.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Dunellen technicians hear about most often before an inspection.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Hairline cracks can widen over a Dunellen 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 sump pump that never stops cycling is often working harder than it should, or is undersized for your Dunellen lot's water table.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Dunellen call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our Dunellen crews trace back to a drainage issue.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Dunellen every day.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Dunellen emergency crews extract standing water first, then diagnose the entry point so it doesn't happen again next storm.
Call for Emergency Service →Hairline cracks are how most Dunellen basements start leaking. We use hydraulic cement injection to seal the crack from the inside out, stopping the leak at the source instead of just painting over the symptom.
Get a Crack Assessment →A tired or undersized sump pump is the #1 reason we get emergency calls in Dunellen after heavy rain. We install dual-pump systems so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection →Some Dunellen lots need both an interior and exterior system working together — we'll tell you honestly if that's the case rather than selling just one.
Ask About Drain Systems →Older Dunellen homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
Get a Crawl Space Quote →We can phase larger Dunellen commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.

We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
You receive a written, itemized quote before any work begins — the number you approve is the number you're billed.
Once the repair is done, you get documentation of the work and a written warranty — not just a handshake.
There's no verbal quote that magically grows once the crew arrives at your Dunellen property — the written estimate is the final word.
Because we're actually based near Dunellen rather than routing calls through a national center, we can usually get someone out the same day you call.
Our repairs come with written, transferable warranties — a real asset if you sell the Dunellen property later.
If your Dunellen basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
We document the damage with photos and a written scope your insurance adjuster can actually use, and we'll walk you through the claim process.
Word of mouth is still how most Dunellen customers find us, which keeps our standards higher than a big out-of-town franchise.
"They came out the same afternoon I called about water coming in during a storm. Explained everything before they touched anything. Basement's been bone dry since."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
"Our old sump pump died during the worst storm of the year, obviously. They had a battery backup system installed within a day. Haven't worried about it since."
"Straightforward commercial quote, no back-and-forth, crew was professional the whole project."
"We had three foundation cracks and expected a huge bill. Turned out only one needed injection — they didn't try to sell us on the other two. That honesty is rare."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
