Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Greenbelt property, gives you a straight answer, and fixes it right the first time.
Free, no-obligation estimates · 24/7 dispatch
Halo Water Proofing started small in the Greenbelt area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Every Greenbelt 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 Greenbelt 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.
📞 +1-866-476-1348Most Greenbelt calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
A musty smell usually means moisture is already moving through your Greenbelt basement, even if the floor looks bone dry.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A Greenbelt 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 — this jumps to the front of our Greenbelt schedule.
Peeling paint near the floor upstairs is one of the last signs Greenbelt homeowners connect to a basement problem.
Whatever's going on with your Greenbelt property, chances are we've already fixed something similar nearby this month.
A flooded Greenbelt basement doesn't wait for morning, and neither do we. Our crews extract it fast and start drying the space the same visit.
Get Emergency Help →Seasonal ground movement in Greenbelt tends to widen existing cracks over time, so sealing early usually costs less than waiting.
Ask About Crack Repair →Already 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 →Some Greenbelt properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →Older Greenbelt homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.
Get a Crawl Space Quote →We handle below-grade waterproofing for Greenbelt property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote →Here's exactly what Greenbelt customers can expect from first call to final walkthrough.
You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
No jargon, no pressure — just a clear look at what's actually going on.
The number you approve is the number you're billed — no change orders once the crew shows up.
You get documentation of the work plus a real warranty — not just a handshake.
We've heard every Greenbelt 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 — what you approve is what you're billed.
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.
We'd rather earn a repeat Greenbelt customer with an honest fix than push a system you don't need.
We can supply the documentation most carriers ask for before approving a Greenbelt claim.
Word of mouth is still how most Greenbelt customers find us, which keeps our standards high.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — 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."
"Straightforward commercial quote, professional crew, no back and forth."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"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 Greenbelt 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.
