Halo Water Proofing is a OH-licensed Interior Drainage System company that treats every Radnor job like it's the only one on the schedule.
Every Radnor technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
Our Radnor 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.

A musty smell usually means moisture is already moving through your Radnor basement, even if the floor looks bone dry.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A pump under constant strain tends to fail during the exact storm that needs it most.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Radnor schedule.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
Whatever's going on with your Radnor property, chances are we've already fixed something similar nearby this month.
