We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
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.
Our New London crew leads carry years of hands-on repair experience, not just sales training โ which is why the advice you get on-site tends to match what actually needs fixing.

๐ +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.
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.
This is one sign we tell New London customers never to wait on โ wall movement tends to progress, not resolve on its own.
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 get it out and start drying the space the same visit.

"Fair price, on time, cleaned up after. Wish every contractor worked this way."
