From a hairline crack to a fully soaked crawl space, our McLean crew has seen it and fixed it. No guesswork, no scare tactics β just a clear plan and a fair price.
Licensed & insured in VA Β· Real warranties
We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
We don't run a bidding war between crews. The McLean technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old McLean 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 McLean technician today, not an automated queue. We'll explain what's going on and get you scheduled.
π +1-866-476-1348Most McLean calls didn't start with a flood β they started with one of these small signs weeks or months earlier.
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 McLean foundation rarely stay small β seasonal ground movement tends to widen them over time.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A pump under constant strain tends to fail during the exact storm that needs it most.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
These upstairs clues usually show up months after the basement moisture problem actually started.
No two McLean basements are the same β soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our McLean emergency line busy β active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help βNot 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 βA failed sump pump is the top reason for emergency calls across McLean after heavy rain β we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check βFor yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options βA damp McLean crawl space drives up humidity throughout the house β we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote βCommercial water intrusion means bigger stakes β inventory, tenants, downtime. We scope commercial McLean jobs with written specs and a real timeline.
Request a Commercial Quote βNo pressure, no scripts β just what actually happens once you call +1-866-476-1348.
A real technician asks the right questions to understand what's likely happening at your McLean property before anyone drives out.
No jargon, no pressure β just a clear look at what's actually going on.
Every McLean quote is written before work starts, not estimated verbally and adjusted later.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every McLean horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts β what you approve is what you're billed.
Our crews stage locally near McLean, which is why most emergency calls get a technician on-site in under two hours.
Warranty terms are explained in plain language before you sign, with no fine-print surprises later.
Our technicians are trained to diagnose accurately, not to upsell β that changes the advice you actually get.
Filing a claim can be confusing β we've walked McLean customers through this process many times.
Every McLean job reflects on the next referral, so we treat each one like it matters.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything β basement's been dry since."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"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 McLean work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
