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

Halo Water Proofing started as a small MN 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.
