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.
Licensed & insured in OH · Real warranties
Halo Water Proofing is a OH-licensed Interior Drainage System 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.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for New London homeowners.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
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 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 — 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.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our New London crews handle most.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
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 →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options →A damp New London crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote →We handle below-grade waterproofing for New London property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
We figure out fast whether this needs an emergency dispatch or a scheduled inspection.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
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.
We've heard every New London horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
We quote the job in writing after seeing it in person, so there's no surprise on the final invoice.
We're not routing your call through a national center — the person who answers is close by.
Warranty terms are explained in plain language before you sign, with no fine-print surprises later.
We'd rather earn a repeat New London customer with an honest fix than push a system you don't need.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Every New London job reflects on the next referral, so we treat each one like it matters.
"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."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"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."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
We back our New London work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
