Halo Water Proofing has been the Dunlap area's go-to call for Foundation Crack Repair because we answer the phone, show up on time, and stand behind the work.

We're Halo Water Proofing — a TN-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Dunlap-area foundations, and exactly how to stop it.

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.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Dunlap technicians hear about most often before an inspection.
Odor is often the first sign Dunlap customers notice, well before any visible water shows up.
Stair-step cracks in block foundations are a common early warning sign we see across Dunlap-area homes.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
Flooring that's cupping or warping near an exterior wall is a common clue our Dunlap crews trace back to a drainage issue.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Dunlap every day.
When your Dunlap basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew around the clock, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service →Hairline cracks are how most Dunlap basements start leaking. We use polyurethane injection to seal the crack from the inside out, stopping the leak at the source instead of just painting over the symptom.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Dunlap lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →For Dunlap properties fighting grading or drainage issues, an exterior French drain can intercept water before it ever reaches the foundation wall at all. We map your yard's slope and water flow before recommending which approach fits.
Ask About Drain Systems →Older Dunlap homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
Get a Crawl Space Quote →Commercial properties in Dunlap carry bigger stakes when water gets in: inventory, tenants, downtime. We scope commercial jobs with the same crew leads who run our residential work, backed by written specs and timelines.

We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
A technician inspects the Dunlap property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
No verbal estimates that change later. What's quoted for your Dunlap job is what's invoiced.
Once the repair is done, you get documentation of the work and a written warranty — not just a handshake.
There's no verbal quote that magically grows once the crew arrives at your Dunlap property — the written estimate is the final word.
Our trucks stage locally around Dunlap, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
If a covered repair fails, we come back and make it right. That's written into every contract, not just promised on the phone.
Our technicians are paid to diagnose correctly, not to upsell — that changes the advice you actually get on-site.
We can supply the photo documentation and repair scope most Dunlap, TN carriers ask for before approving a claim.
Every Dunlap job reflects on the next referral, so we treat each one like it's the only advertising that matters.
"They came out the same afternoon I called about water coming in during a storm. Explained everything before they touched anything. Basement's been bone dry since."
"Got quotes from three companies for a crack repair. These guys were the only ones who actually explained why the crack was happening instead of just quoting a price."
"Our old sump pump died during the worst storm of the year, obviously. They had a battery backup system installed within a day. Haven't worried about it since."
"Straightforward commercial quote, no back-and-forth, crew was professional the whole project."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Technician actually explained why the water was coming in instead of just quoting a number. First contractor who's done that for us."
