Halo Water Proofing has been the trusted call for Exterior Waterproofing across Columbia because we answer the phone, show up when we say, and stand behind the work.
Licensed & insured in SC · Real warranties
Halo Water Proofing started small in the Columbia area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Our Columbia 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 Columbia 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.

Get Emergency Help →We seal active Columbia foundation cracks with hydraulic cement injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across Columbia after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.

Every Columbia 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."
"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."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
Every Columbia 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.
