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.

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.
Odor is often the first sign McLean customers notice, well before any visible water shows up.
Hairline cracks can widen over a McLean winter's freeze-thaw cycle and become active leak points by spring.
That white chalky film on basement walls is efflorescence β mineral deposits left behind as water evaporates through concrete.
A pump under constant strain tends to fail at the worst possible time β usually during the next big McLean storm.
This is one sign we tell McLean customers not to wait on β wall movement tends to progress rather than resolve on its own.
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 around the clock, 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 βAlready have a sump pump that's failing or too small for your McLean lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume β not the cheapest unit on the truck.
Schedule a Pump Inspection βFor McLean 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 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 can phase larger McLean commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.
Request a Commercial Quote βNo confusing steps, no hard sell β just the same process our McLean crews follow on every job.
We start with a phone conversation, not a script β enough to know whether this is an emergency dispatch or a scheduled inspection.
A technician inspects the McLean property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
You receive a written, itemized quote before any work begins β the number you approve is the number you're billed.
Once the repair is done, you get documentation of the work and a written warranty β not just a handshake.
There's no verbal quote that magically grows once the crew arrives at your McLean property β the written estimate is the final word.
Because we're actually based near McLean rather than routing calls through a national center, we can usually get someone out the same day you call.
Our repairs come with written, transferable warranties β a real asset if you sell the McLean property later.
Our technicians are paid to diagnose correctly, not to upsell β that changes the advice you actually get on-site.
Filing a water damage claim in McLean, VA can be confusing β we've done it enough times with McLean adjusters to help you avoid common denials.
Word of mouth is still how most McLean customers find us, which keeps our standards higher than a big out-of-town franchise.
"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."
"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
"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."
