Halo Water Proofing has been the Ashburn area's go-to call for Emergency Waterproofing because we answer the phone, show up on time, and stand behind the work.

We're Halo Water Proofing — a VA-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Ashburn-area foundations, and exactly how to stop it.

We don't send apprentices to figure it out on your dime. Every Ashburn job is run by a technician who has done this exact repair dozens of times, with a supervisor who signs off before we call it finished.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Ashburn technicians hear about most often before an inspection.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Stair-step cracks in block foundations are a common early warning sign we see across Ashburn-area homes.
Efflorescence is a clear sign that water is actively passing through your Ashburn foundation wall, even if you've never seen standing water.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Ashburn call we prioritize fast.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
Every Ashburn property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Ashburn emergency crews extract standing water first, then diagnose the source so it doesn't happen again next storm.
Call for Emergency Service →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our Ashburn crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Ashburn lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →For Ashburn properties fighting grading or drainage issues, an exterior French drain can intercept water before it ever reaches the foundation wall at all. We map your yard's slope and water flow before recommending which approach fits.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Ashburn crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →We can phase larger Ashburn commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Ashburn crews follow on every job.
We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
No verbal estimates that change later. What's quoted for your Ashburn job is what's invoiced.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
We quote the job in writing after inspecting it in person, so what you agree to on the phone or at your door is what shows up on the final invoice.
Our trucks stage locally around Ashburn, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
Our repairs come with written, transferable warranties — a real asset if you sell the Ashburn property later.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
We document the damage with photos and a written scope your insurance adjuster can actually use, and we'll walk you through the claim process.
Our name is on trucks driving around Ashburn every day — we don't cut corners on a job our neighbors will see.
"They came out the same afternoon I called about water coming in during a storm. Explained everything before they touched anything. Basement's been bone dry since."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
"Our old sump pump died during the worst storm of the year, obviously. They had a battery backup system installed within a day. Haven't worried about it since."
"Straightforward commercial quote, no back-and-forth, crew was professional the whole project."
"We had three foundation cracks and expected a huge bill. Turned out only one needed injection — they didn't try to sell us on the other two. That honesty is rare."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
Whether you're in the older, established parts of Ashburn or a newer subdivision still settling, our crews have likely already worked on a foundation like yours nearby.
