Halo Water Proofing has been the trusted call for Waterproofing across Union because we answer the phone, show up when we say, and stand behind the work.
Licensed & insured in SC · Written pricing
Halo Water Proofing started small in the Union area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Our Union crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
Our Union 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.
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 Union crews hear about most.
Odor is often the very first clue Union homeowners notice, well before any water is visible.
Small cracks in a Union foundation rarely stay small — seasonal ground movement tends to widen them over time.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A pump under constant strain tends to fail during the exact storm that needs it most.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
Whatever's going on with your Union property, chances are we've already fixed something similar nearby this month.
Storm season keeps our Union emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
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.
Ask About Crack Repair →Most Union pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check →An interior drain tile system routes water to a sump pump before it reaches your Union basement floor at all.
Talk Drainage Options →A damp Union 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 →We can phase larger Union commercial projects around business hours or tenant schedules so operations keep running.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
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.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every Union 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.
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.
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 Union claim.
Word of mouth is still how most Union customers find us, which keeps our standards high.
"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."
"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."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"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 Union contract we sign.
