Halo Water Proofing has been the trusted call for Wet Basement Repair across Greenbelt because we answer the phone, show up when we say, and stand behind the work.
Licensed & insured in MD · 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 Greenbelt technician who inspects your property is the same one who does the repair, start to finish.
Our Greenbelt crew leads carry years of hands-on repair experience, not just sales training — which is why the advice you get on-site tends to match what actually needs fixing.
Talk to a real Greenbelt technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Most Greenbelt calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
Odor is often the very first clue Greenbelt homeowners notice, well before any water is visible.
Stair-step cracking in block foundations is one of the most common early signs our Greenbelt crews see.
Efflorescence is a reliable early sign that water is moving through your Greenbelt foundation wall right now.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Greenbelt schedule.
These upstairs clues usually show up months after the basement moisture problem actually started.
Whatever's going on with your Greenbelt property, chances are we've already fixed something similar nearby this month.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
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.

We figure out fast whether this needs an emergency dispatch or a scheduled inspection.
No jargon, no pressure — just a clear look at what's actually going on.
Every Greenbelt 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 Greenbelt horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
There's no verbal quote that grows once the crew shows up — the written estimate is final.
We're not routing your call through a national center — the person who answers is close by.
Our major repairs come with written, transferable warranties — useful if you sell the Greenbelt property later.
Our technicians are trained to diagnose accurately, not to upsell — that changes the advice you actually get.
We can supply the documentation most carriers ask for before approving a Greenbelt claim.
Every Greenbelt 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."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"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."
We back our Greenbelt work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
