Halo Water Proofing started small in the New London area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.

We've worked on foundations from decades-old New London homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
Talk to a real New London technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our New London crews hear about most.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Stair-step cracking in block foundations is one of the most common early signs our New London crews see.
Efflorescence is a reliable early sign that water is moving through your New London foundation wall right now.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Peeling paint near the floor upstairs is one of the last signs New London homeowners connect to a basement problem.
No two New London basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
