From a hairline crack to a fully soaked crawl space, our Dunkirk crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.
Free, no-obligation estimates · 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 Dunkirk technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
Our Dunkirk crew leads carry years of hands-on repair experience, not just sales training — which is why the advice you get on-site tends to match what actually needs fixing.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.

Odor is often the very first clue Dunkirk homeowners notice, well before any water is visible.
Stair-step cracking in block foundations is one of the most common early signs our Dunkirk crews see.

"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."
"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."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
