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

We're Halo Water Proofing — a NJ-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Annandale-area foundations, and exactly how to stop it.

We don't send apprentices to figure it out on your dime. Every Annandale 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 Annandale 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 Annandale winter's freeze-thaw cycle and become active leak points by spring.
Efflorescence is a clear sign that water is actively passing through your Annandale foundation wall, even if you've never seen standing water.
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 Annandale customers not to wait on — wall movement tends to progress rather than resolve on its own.
These signs upstairs are often the last clue Annandale homeowners notice, even though the moisture issue started in the basement months earlier.
Every Annandale property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Storm season in Annandale, NJ means our emergency line gets busy fast — we triage calls by severity so active flooding at your Annandale address jumps the queue ahead of routine inspections.
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 Annandale crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →A tired or undersized sump pump is the #1 reason we get emergency calls in Annandale 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 →An interior drain tile system channels water to a sump pump before it ever reaches your Annandale basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Annandale crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →Commercial properties in Annandale carry bigger stakes when water gets in: inventory, tenants, downtime. We scope commercial jobs with the same crew leads who run our residential work, backed by written specs and timelines.
