Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Uniondale property, gives you a straight answer, and fixes it right the first time.
Background-checked Uniondale technicians · 24/7 dispatch
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.
Our Uniondale crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
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.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Uniondale crews hear about most.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Small cracks in a Uniondale foundation rarely stay small — seasonal ground movement tends to widen them over time.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
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.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
Whatever's going on with your Uniondale property, chances are we've already fixed something similar nearby this month.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.

Every Uniondale job reflects on the next referral, so we treat each one like it matters.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
