Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Herndon property, gives you a straight answer, and fixes it right the first time.
Licensed & insured in VA · Written pricing
Halo Water Proofing started small in the Herndon area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Our Herndon crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
We've worked on foundations from decades-old Herndon homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
Talk to a real Herndon technician today, not an automated queue. We'll explain what's going on and get you scheduled.

If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Small cracks in a Herndon foundation rarely stay small — seasonal ground movement tends to widen them over time.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A pump under constant strain tends to fail during the exact storm that needs it most.
This is one sign we tell Herndon customers never to wait on — wall movement tends to progress, not resolve on its own.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
Whatever's going on with your Herndon property, chances are we've already fixed something similar nearby this month.
Storm season keeps our Herndon emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →Not every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
Ask About Crack Repair →Most Herndon pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check →Some Herndon properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →A damp Herndon crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial Herndon jobs with written specs and a real timeline.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
A Herndon technician walks the property, checks the foundation and drainage, and explains what's found in plain language.

Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.
Plenty of companies advertise Vapor Barrier Installation in Herndon — here's what actually separates the ones worth calling from the ones that aren't.
There's no verbal quote that grows once the crew shows up — the written estimate is final.
Our crews stage locally near Herndon, which is why most emergency calls get a technician on-site in under two hours.

We'd rather earn a repeat Herndon customer with an honest fix than push a system you don't need.
Filing a claim can be confusing — we've walked Herndon customers through this process many times.
Our trucks are recognizable around Herndon — we don't cut corners on jobs our neighbors will see.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Straightforward commercial quote, professional crew, no back and forth."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
We back our Herndon work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
