Free, no-obligation estimates ยท 24/7 dispatch

Halo Water Proofing is a VA-licensed Sump Pump Installation company that treats every Fairfax job like it's the only one on the schedule.
Our Fairfax 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 Fairfax 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 Fairfax technician today, not an automated queue. We'll explain what's going on and get you scheduled.
๐ +1-866-476-1348Most Fairfax calls didn't start with a flood โ they started with one of these small signs weeks or months earlier.
Odor is often the very first clue Fairfax homeowners notice, well before any water is visible.
Stair-step cracking in block foundations is one of the most common early signs our Fairfax crews see.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A Fairfax sump pump that never rests is usually undersized or nearing the end of its life.
A wall that's starting to bow is a structural issue on top of a water issue โ this jumps to the front of our Fairfax schedule.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
No two Fairfax basements are the same โ soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Fairfax emergency line busy โ active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help โWe seal active Fairfax foundation cracks with epoxy injection โ stopping the leak at its source instead of patching the surface.
Ask About Crack Repair โAlready have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
Book a Pump Check โAn interior drain tile system routes water to a sump pump before it reaches your Fairfax basement floor at all.
Talk Drainage Options โMusty smell upstairs with no obvious source? Check the crawl space first โ it's usually the culprit.
Get a Crawl Space Quote โWe handle below-grade waterproofing for Fairfax property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote โHere's exactly what Fairfax customers can expect from first call to final walkthrough.
You'll talk to a person, not a script โ enough of a conversation to know what to expect before anyone shows up.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
Every Fairfax 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.
Plenty of companies advertise Sump Pump Installation in Fairfax โ here's what actually separates the ones worth calling from the ones that aren't.
We quote the job in writing after seeing it in person, so there's no surprise on the final invoice.
A local dispatch model means the technician who answers your questions is the same one who shows up.
If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.
Our technicians are trained to diagnose accurately, not to upsell โ that changes the advice you actually get.
Filing a claim can be confusing โ we've walked Fairfax customers through this process many times.
Every Fairfax 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 โ basement's been dry since."
"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."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
Every Fairfax technician we send is background-checked and trained on the systems we install, so the crew that inspects your property is the same one that fixes it.
