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 · Real warranties
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.
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.
A musty smell usually means moisture is already moving through your New London basement, even if the floor looks bone dry.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
This is one sign we tell New London customers never to wait on — wall movement tends to progress, not resolve on its own.
These upstairs clues usually show up months after the basement moisture problem actually started.
No two New London basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
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 →Most New London pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
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 →Musty smell upstairs with no obvious source? Check the crawl space first — it's usually the culprit.

A real technician asks the right questions to understand what's likely happening at your New London property before anyone drives out.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
The number you approve is the number you're billed — no change orders once the crew shows up.
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.
You get a real number before any work starts — what you approve is what you're billed.
A local dispatch model means the technician who answers your questions is the same one who shows up.
Our major repairs come with written, transferable warranties — useful if you sell the New London property later.
We'd rather earn a repeat New London customer with an honest fix than push a system you don't need.
Filing a claim can be confusing — we've walked New London customers through this process many times.
Word of mouth is still how most New London customers find us, which keeps our standards high.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
"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."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"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.
