From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Marlboro 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 Marlboro customers kept referring us to neighbors — that's still how most of our work comes in today.

Every technician on our Marlboro 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 Marlboro technicians hear about most often before an inspection.
Odor is often the first sign Marlboro customers notice, well before any visible water shows up.
Stair-step cracks in block foundations are a common early warning sign we see across Marlboro-area homes.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Marlboro lot's water table.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Marlboro call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our Marlboro crews trace back to a drainage issue.
Every Marlboro property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
When your Marlboro 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 →Freeze-thaw cycles in Marlboro, 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 →Most sump pump failures we see in Marlboro happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →For Marlboro 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 →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Marlboro crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →We work directly with Marlboro property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Marlboro crews follow on every job.
