From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Dunlap before. We show up, we diagnose it straight, and we fix it right.

Halo Water Proofing started as a small TN crew and grew because Dunlap customers kept referring us to neighbors — that's still how most of our work comes in today.

We don't send apprentices to figure it out on your dime. Every Dunlap job is run by a technician who has done this exact repair dozens of times, with a supervisor who signs off before we call it finished.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.
📞 +1-866-476-1348Most Dunlap customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
Odor is often the first sign Dunlap customers notice, well before any visible water shows up.
Hairline cracks can widen over a Dunlap winter's freeze-thaw cycle and become active leak points by spring.
Efflorescence is a clear sign that water is actively passing through your Dunlap foundation wall, even if you've never seen standing water.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Dunlap lot's water table.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
These signs upstairs are often the last clue Dunlap homeowners notice, even though the moisture issue started in the basement months earlier.
Every Dunlap property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Storm season in Dunlap, TN means our emergency line gets busy fast — we triage calls by severity so active flooding at your Dunlap address jumps the queue ahead of routine inspections.
Call for Emergency Service →Freeze-thaw cycles in Dunlap, TN push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
