From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Montville before. We show up, we diagnose it straight, and we fix it right.

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

Every technician on our Montville crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
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.
📞 +1-866-476-1348Most Montville customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
Odor is often the first sign Montville customers notice, well before any visible water shows up.
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
This is one sign we tell Montville customers not to wait on — wall movement tends to progress rather than resolve on its own.
These signs upstairs are often the last clue Montville homeowners notice, even though the moisture issue started in the basement months earlier.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Montville every day.
When your Montville basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew around the clock, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service →Hairline cracks are how most Montville 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 Montville 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 →For Montville 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 Montville 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 Montville 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.

If your Montville 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.

"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"Got quotes from three companies for a crack repair. These guys were the only ones who actually explained why the crack was happening instead of just quoting a price."

"Straightforward commercial quote, no back-and-forth, crew was professional the whole project."
