From a hairline crack to a fully soaked crawl space, our Fairfax crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.
Background-checked Fairfax technicians · Real warranties
Halo Water Proofing started small in the Fairfax area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Every Fairfax technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
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 — not a vague callback promise.

Get Emergency Help →We seal active Fairfax foundation cracks with hydraulic cement injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Already have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
