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

Halo Water Proofing started as a small WI crew and grew because New London 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 New London 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 New London customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of New London call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our New London 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 New London every day.
When your New London 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 New London 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 →A tired or undersized sump pump is the #1 reason we get emergency calls in New London after heavy rain. We install battery backup units so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection →For New London 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 →A damp, uninsulated crawl space under a New London home drives up humidity, invites mold, and wastes energy year-round. We seal it with heavy-duty vapor barrier, address any standing moisture, and can add dehumidification if needed.
Get a Crawl Space Quote →We can phase larger New London commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.

"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"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."
