From a hairline crack to a fully soaked crawl space, our Manhasset crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.
Licensed & insured in NY · Real warranties
We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
Every Manhasset technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
We've worked on foundations from decades-old Manhasset homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
Talk to a real Manhasset technician today, not an automated queue. We'll explain what's going on and get you scheduled.

If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
Efflorescence is a reliable early sign that water is moving through your Manhasset foundation wall right now.
A pump under constant strain tends to fail during the exact storm that needs it most.
This is one sign we tell Manhasset customers never to wait on — wall movement tends to progress, not resolve on its own.
These upstairs clues usually show up months after the basement moisture problem actually started.
Whatever's going on with your Manhasset property, chances are we've already fixed something similar nearby this month.
A flooded Manhasset basement doesn't wait for morning, and neither do we. Our crews extract it fast and start drying the space the same visit.
