Free, no-obligation estimates · 24/7 dispatch
Halo Water Proofing started small in the Uniondale area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Every Uniondale 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 Uniondale 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 Uniondale technician today, not an automated queue. We'll explain what's going on and get you scheduled.

"Straightforward commercial quote, professional crew, no back and forth."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
