Halo Water Proofing has been the Brooklyn 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 NY-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Brooklyn-area foundations, and exactly how to stop it.

Every technician on our Brooklyn 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.
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 Brooklyn technicians hear about most often before an inspection.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
Efflorescence is a clear sign that water is actively passing through your Brooklyn 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.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Brooklyn call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our Brooklyn crews trace back to a drainage issue.
Every Brooklyn property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Brooklyn emergency crews extract standing water first, then diagnose the source so it doesn't happen again next storm.
Call for Emergency Service →Freeze-thaw cycles in Brooklyn, NY push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Brooklyn lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →For Brooklyn 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 →Older Brooklyn homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
Get a Crawl Space Quote →We work directly with Brooklyn property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.

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.
No verbal estimates that change later. What's quoted for your Brooklyn job is what's invoiced.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
We quote the job in writing after inspecting it in person, so what you agree to on the phone or at your door is what shows up on the final invoice.
A local dispatch model means the technician who answers questions about your Brooklyn job is the same one who shows up to do it.
Our repairs come with written, transferable warranties — a real asset if you sell the Brooklyn property later.
If your Brooklyn basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
We can supply the photo documentation and repair scope most Brooklyn, NY carriers ask for before approving a claim.
Word of mouth is still how most Brooklyn customers find us, which keeps our standards higher than a big out-of-town franchise.
"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."
"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."
"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
