Background-checked Welcome technicians · Real warranties
Halo Water Proofing is a SC-licensed Basement Waterproofing company that treats every Welcome job like it's the only one on the schedule.
Our Welcome 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 Welcome 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 Welcome 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 Welcome homeowners notice, well before any water is visible.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A Welcome 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 Welcome schedule.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Welcome crews handle most.
A flooded Welcome 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 →We seal active Welcome foundation cracks with hydraulic cement injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Most Welcome pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options →A damp Welcome crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial Welcome jobs with written specs and a real timeline.
Request a Commercial Quote →Here's exactly what Welcome 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.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
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 Welcome horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
We quote the job in writing after seeing it in person, so there's no surprise on the final invoice.
We're not routing your call through a national center — the person who answers is close by.
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 Welcome 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 Welcome claim.
Word of mouth is still how most Welcome 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."
"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."
"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 Welcome 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.
