From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Alexandria before. We show up, we diagnose it straight, and we fix it right.

Halo Water Proofing started as a small IN crew and grew because Alexandria customers kept referring us to neighbors — that's still how most of our work comes in today.

Every technician on our Alexandria crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Most Alexandria 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 — they rarely stay small once seasonal ground movement gets involved.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
This is one sign we tell Alexandria customers not to wait on — 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 Alexandria crews trace back to a drainage issue.
Every Alexandria property is different — 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 Alexandria emergency crews pump out the basement first, then diagnose the entry point so it doesn't happen again next storm.
Call for Emergency Service →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our Alexandria crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →A tired or undersized sump pump is the #1 reason we get emergency calls in Alexandria 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 →An interior drain tile system channels water to a sump pump before it ever reaches your Alexandria basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Alexandria crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →We can phase larger Alexandria commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.

You call +1-866-476-1348 and talk to a real technician who asks the right questions to understand what's likely happening at your Alexandria property.
A technician inspects the Alexandria 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 — 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 — not just a handshake.
You get a written number before any work begins — the price you approve is the price you pay, no change-order games.
Because we're actually based near Alexandria rather than routing calls through a national center, we can usually get someone out the same day you call.
If a covered repair fails, we come back and make it right. That's written into every contract, not just promised on the phone.
Our technicians are paid to diagnose correctly, not to upsell — that changes the advice you actually get on-site.
We document the damage with photos and a written scope your insurance adjuster can actually use, and we'll walk you through the claim process.
Every Alexandria job reflects on the next referral, so we treat each one like it's the only advertising that matters.
"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
"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."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
