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 OH crew and grew because New London customers kept referring us to neighbors — that's still how most of our work comes in today.

Every technician on our New London crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +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.
Odor is often the first sign New London customers notice, well before any visible water shows up.
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
