Halo Water Proofing has been the Lorton area's go-to call for Exterior 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 Lorton-area foundations, and exactly how to stop it.
We don't send apprentices to figure it out on your dime. Every Lorton 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.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Lorton 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."
Hairline cracks can widen over a Lorton winter's freeze-thaw cycle and become active leak points by spring.
Efflorescence is a clear sign that water is actively passing through your Lorton foundation wall, even if you've never seen standing water.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Lorton lot's water table.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Lorton every day.
Storm season in Lorton, VA means our emergency line gets busy fast — we triage calls by severity so active flooding at your Lorton address jumps the queue ahead of routine inspections.
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 Lorton crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →A tired or undersized sump pump is the #1 reason we get emergency calls in Lorton after heavy rain. We install right-sized primary pumps so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection →For Lorton 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 →Older Lorton homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
Get a Crawl Space Quote →We work directly with Lorton property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Lorton crews follow on every job.

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.

We can supply the photo documentation and repair scope most Lorton, VA carriers ask for before approving a claim.
Word of mouth is still how most Lorton customers find us, which keeps our standards higher than a big out-of-town franchise.
"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."
"Got quotes from three companies for a crack repair. These guys were the only ones who actually explained why the crack was happening instead of just quoting a price."
"Crawl space smelled awful for years. Encapsulation crew did a clean job and the smell is completely gone upstairs now."
"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."
