Licensed & insured in MD · Real warranties
Halo Water Proofing started small in the Olney area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Every Olney technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
We've worked on foundations from decades-old Olney 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.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Olney crews hear about most.
Odor is often the very first clue Olney homeowners notice, well before any water is visible.
Stair-step cracking in block foundations is one of the most common early signs our Olney crews see.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
This is one sign we tell Olney 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.
No two Olney basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Olney emergency line busy — active flooding always jumps ahead of routine inspections in the queue.

Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.

We're not routing your call through a national center — the person who answers is close by.

Every Olney job reflects on the next referral, so we treat each one like it matters.
"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."
"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."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
If a covered repair doesn't hold up, we come back and make it right — no arguing, no extra invoice. That's written into every Olney contract we sign.
