Halo Water Proofing is a VA-licensed Crawl Space Encapsulation company that treats every Fairfax job like it's the only one on the schedule.
Every Fairfax technician we send is background-checked and trained on the exact equipment we install โ not a subcontractor picked up for the day.

Odor is often the very first clue Fairfax homeowners notice, well before any water is visible.
Small cracks in a Fairfax foundation rarely stay small โ seasonal ground movement tends to widen them over time.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.

A wall that's starting to bow is a structural issue on top of a water issue โ this jumps to the front of our Fairfax schedule.
Peeling paint near the floor upstairs is one of the last signs Fairfax homeowners connect to a basement problem.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Fairfax crews handle most.
