From a hairline crack to a fully soaked crawl space, our New London crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.
Background-checked New London technicians · 24/7 dispatch
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 don't run a bidding war between crews. The New London technician who inspects your property is the same one who does the repair, start to finish.
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.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.

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.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A pump under constant strain tends to fail during the exact storm that needs it most.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
Whatever's going on with your New London property, chances are we've already fixed something similar nearby this month.
A flooded New London basement doesn't wait for morning, and neither do we. Our crews extract it fast and start drying the space the same visit.
