Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your McLean property, gives you a straight answer, and fixes it right the first time.
Background-checked McLean technicians Β· 24/7 dispatch

Halo Water Proofing started small in the McLean area and grew because customers kept referring us to their neighbors β that's still how most of our work comes in today.
We don't run a bidding war between crews. The McLean technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old McLean 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 β not a vague callback promise.

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 McLean foundation rarely stay small β seasonal ground movement tends to widen them over time.
Efflorescence is a reliable early sign that water is moving through your McLean foundation wall right now.
A McLean sump pump that never rests is usually undersized or nearing the end of its life.
A wall that's starting to bow is a structural issue on top of a water issue β this jumps to the front of our McLean schedule.
These upstairs clues usually show up months after the basement moisture problem actually started.
Whatever's going on with your McLean property, chances are we've already fixed something similar nearby this month.
A flooded McLean basement doesn't wait for morning, and neither do we. Our crews extract it fast and start drying the space the same visit.

"French drain install took two days exactly as quoted, and the yard looked better than before."
