Licensed & insured in NJ · Real warranties
Halo Water Proofing is a NJ-licensed Crawl Space Encapsulation company that treats every Manville job like it's the only one on the schedule.
Every Manville technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
Our Manville crew leads carry years of hands-on repair experience, not just sales training — which is why the advice you get on-site tends to match what actually needs fixing.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.

If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Small cracks in a Manville foundation rarely stay small — seasonal ground movement tends to widen them over time.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
This is one sign we tell Manville customers never to wait on — wall movement tends to progress, not resolve on its own.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
Whatever's going on with your Manville property, chances are we've already fixed something similar nearby this month.
Storm season keeps our Manville emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →We seal active Manville foundation cracks with polyurethane injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across Manville after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check →Some Manville properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →Musty smell upstairs with no obvious source? Check the crawl space first — it's usually the culprit.
Get a Crawl Space Quote →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial Manville jobs with written specs and a real timeline.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
A real technician asks the right questions to understand what's likely happening at your Manville 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 Manville horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
There's no verbal quote that grows once the crew shows up — the written estimate is final.
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.
If your Manville basement just needs a small crack seal instead of a full system, that's exactly what we'll tell you.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Every Manville 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."
"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."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
We back our Manville work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
