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

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.
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 +1-866-476-1348Most McLean customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
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.
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.
Every McLean property is different β 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 McLean emergency crews pump out the basement first, then diagnose the entry point so it doesn't happen again next storm.
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 βA tired or undersized sump pump is the #1 reason we get emergency calls in McLean 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 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 βCommercial properties in McLean carry bigger stakes when water gets in: inventory, tenants, downtime. We scope commercial jobs with the same crew leads who run our residential work, backed by written specs and timelines.

"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell β just fixed it."
"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."
"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 β 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."
