Halo Water Proofing has been the trusted call for Basement Waterproofing across Fairfax because we answer the phone, show up when we say, and stand behind the work.
Background-checked Fairfax technicians ยท Real warranties

Halo Water Proofing started small in the Fairfax area and grew because customers kept referring us to their neighbors โ that's still how most of our work comes in today.
We don't run a bidding war between crews. The Fairfax technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Fairfax 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 Fairfax crews hear about most.
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 Fairfax foundation rarely stay small โ seasonal ground movement tends to widen them over time.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
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 โ this jumps to the front of our Fairfax schedule.
These upstairs clues usually show up months after the basement moisture problem actually started.
No two Fairfax basements are the same โ soil type, age of the home, water table. We match the fix to your actual problem.
When water shows up fast, we move fast โ extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help โWe seal active Fairfax foundation cracks with epoxy injection โ stopping the leak at its source instead of patching the surface.
Ask About Crack Repair โA failed sump pump is the top reason for emergency calls across Fairfax after heavy rain โ we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check โSome Fairfax properties need both systems working together โ we'll say so honestly instead of selling just one.
Talk Drainage Options โOlder Fairfax homes with vented crawl spaces see the biggest swings in seasonal humidity โ encapsulation closes that off for good.
