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.
Our New London crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
Our New London crew leads carry years of hands-on repair experience, not just sales training — which is why the advice you get on-site tends to match what actually needs fixing.
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.
Small cracks in a New London foundation rarely stay small — seasonal ground movement tends to widen them over time.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A New London sump pump that never rests is usually undersized or nearing the end of its life.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
These upstairs clues usually show up months after the basement moisture problem actually started.
Whatever's going on with your New London property, chances are we've already fixed something similar nearby this month.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help →Seasonal ground movement in New London tends to widen existing cracks over time, so sealing early usually costs less than waiting.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across New London after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check →Some New London properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →Older New London homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.

No verbal number that quietly grows once the truck pulls up — the written quote is the final word.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.

Word of mouth is still how most New London customers find us, which keeps our standards high.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Straightforward commercial quote, professional crew, no back and forth."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
