Background-checked New London technicians · 24/7 dispatch
Halo Water Proofing is a OH-licensed Exterior Waterproofing company that treats every New London job like it's the only one on the schedule.
Every New London technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
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.
📞 +1-866-476-1348Most New London calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
Odor is often the very first clue New London homeowners notice, well before any water is visible.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
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.
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.
Storm season keeps our New London emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →Not every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
Ask About Crack Repair →Already have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
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.

Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
No jargon, no pressure — just a clear look at what's actually going on.
Every New London quote is written before work starts, not estimated verbally and adjusted later.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.

If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.

Our trucks are recognizable around New London — we don't cut corners on jobs our neighbors will see.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."
