Wet basement? Cracked foundation? A Halo Water Proofing crew can be at your McLean property within hours β upfront pricing, no guesswork, no pressure.

Halo Water Proofing started as a small VA crew and grew because McLean customers kept referring us to neighbors β that's still how most of our work comes in today.

We don't send apprentices to figure it out on your dime. Every McLean 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 β not a call-back promise.
π +1-866-476-1348Water problems rarely announce themselves all at once β they usually show up as small clues first. Here's what our McLean 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 McLean-area homes.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your McLean lot's water table.
A bowing basement wall is a structural concern in addition to a water one β this is the kind of McLean call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our McLean crews trace back to a drainage issue.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in McLean every day.
Storm season in McLean, VA means our emergency line gets busy fast β we triage calls by severity so active flooding at your McLean address jumps the queue ahead of routine inspections.
Call for Emergency Service βA cracked foundation wall isn't just a cosmetic issue β it's a water entry point and, over time, a structural one. Our McLean crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment βMost sump pump failures we see in McLean happen during the exact storms that need them most β a battery backup closes that gap when the power drops.
Schedule a Pump Inspection βSome McLean lots need both an interior and exterior system working together β we'll tell you honestly if that's the case rather than selling just one.
Ask About Drain Systems βOlder McLean homes with vented crawl spaces are especially prone to seasonal moisture swings β encapsulation closes that off for good.
Get a Crawl Space Quote βWe work directly with McLean property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections β scheduled around your operating hours.

No verbal estimates that change later. What's quoted for your McLean job is what's invoiced.

"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."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Technician actually explained why the water was coming in instead of just quoting a number. First contractor who's done that for us."
