Halo Water Proofing has been the trusted call for Exterior Waterproofing across Ashburn because we answer the phone, show up when we say, and stand behind the work.
Licensed & insured in VA · Real warranties
Halo Water Proofing started small in the Ashburn area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Our Ashburn crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
We've worked on foundations from decades-old Ashburn 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.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Ashburn crews hear about most.
A musty smell usually means moisture is already moving through your Ashburn basement, even if the floor looks bone dry.
Small cracks in a Ashburn foundation rarely stay small — 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 Ashburn 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 — this jumps to the front of our Ashburn schedule.
These upstairs clues usually show up months after the basement moisture problem actually started.
Whatever's going on with your Ashburn property, chances are we've already fixed something similar nearby this month.
A flooded Ashburn basement doesn't wait for morning, and neither do we. Our crews extract it fast and start drying the space the same visit.
Get Emergency Help →Seasonal ground movement in Ashburn tends to widen existing cracks over time, so sealing early usually costs less than waiting.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across Ashburn after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.

We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
Every Ashburn quote is written before work starts, not estimated verbally and adjusted later.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every Ashburn horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
There's no verbal quote that grows once the crew shows up — the written estimate is final.
A local dispatch model means the technician who answers your questions is the same one who shows up.

Filing a claim can be confusing — we've walked Ashburn customers through this process many times.
Every Ashburn job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
If a covered repair doesn't hold up, we come back and make it right — no arguing, no extra invoice. That's written into every Ashburn contract we sign.
