From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Brooklyn before. We show up, we diagnose it straight, and we fix it right.
Halo Water Proofing started as a small NY crew and grew because Brooklyn customers kept referring us to neighbors — that's still how most of our work comes in today.
We don't send apprentices to figure it out on your dime. Every Brooklyn 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.
📞 +1-866-476-1348Most Brooklyn customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
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.
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 Brooklyn lot's water table.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Brooklyn call we prioritize fast.
These signs upstairs are often the last clue Brooklyn homeowners notice, even though the moisture issue started in the basement months earlier.
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.
Storm season in Brooklyn, NY means our emergency line gets busy fast — we triage calls by severity so active flooding at your Brooklyn address jumps the queue ahead of routine inspections.
Call for Emergency Service →Hairline cracks are how most Brooklyn basements start leaking. We use polyurethane 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 Brooklyn after heavy rain. We install battery backup units so your basement stays dry even if the power goes out mid-storm.
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 →A damp, uninsulated crawl space under a Brooklyn 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 Brooklyn commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.

You receive a written, itemized quote before any work begins — the number you approve is the number you're billed.
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.
Our trucks stage locally around Brooklyn, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
Warranty terms are explained before you sign, in plain language, so there's no fine print surprise if you ever need to use it.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
