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

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

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.
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.
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.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
Even small cracks are worth a second look β they rarely stay small once seasonal ground movement gets involved.
Efflorescence is a clear sign that water is actively passing through your McLean 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 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.
When your McLean basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew fast, pull the water, and start drying the space with commercial-grade equipment the same visit.
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 βMusty smell upstairs that you can't explain? It's usually the crawl space. Our McLean crews encapsulate the space fully β floor, walls, and vents β so moisture stops migrating into your living areas.
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.

Every McLean job reflects on the next referral, so we treat each one like it's the only advertising that matters.
"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."
"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."
"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
"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."
Whether you're in the older, established parts of McLean or a newer subdivision still settling, our crews have likely already worked on a foundation like yours nearby.
