Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Herndon property, gives you a straight answer, and fixes it right the first time.
Background-checked Herndon technicians ยท 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.
We don't run a bidding war between crews. The Herndon technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Herndon 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.
One phone call gets you a straight answer and a real appointment โ not a vague callback promise.
๐ +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Herndon crews hear about most.
A musty smell usually means moisture is already moving through your Herndon 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.
Efflorescence is a reliable early sign that water is moving through your Herndon foundation wall right now.
A Herndon sump pump that never rests is usually undersized or nearing the end of its life.
This is one sign we tell Herndon customers never to wait on โ wall movement tends to progress, not resolve on its own.
