Free, no-obligation estimates · Real warranties
Halo Water Proofing started small in the Great Neck area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Every Great Neck 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 Great Neck 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 Great Neck 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.

It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Peeling paint near the floor upstairs is one of the last signs Great Neck homeowners connect to a basement problem.
Whatever's going on with your Great Neck property, chances are we've already fixed something similar nearby this month.
Storm season keeps our Great Neck emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →We seal active Great Neck foundation cracks with hydraulic cement injection — stopping the leak at its source instead of patching the surface.
