From a hairline crack to a fully soaked crawl space, our Oshkosh crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.
Background-checked Oshkosh technicians · 24/7 dispatch
Halo Water Proofing started small in the Oshkosh area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
We don't run a bidding war between crews. The Oshkosh technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Oshkosh 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.

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.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Oshkosh schedule.
Peeling paint near the floor upstairs is one of the last signs Oshkosh homeowners connect to a basement problem.
No two Oshkosh basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Oshkosh 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 →A failed sump pump is the top reason for emergency calls across Oshkosh after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.

Talk Drainage Options →Musty smell upstairs with no obvious source? Check the crawl space first — it's usually the culprit.
Get a Crawl Space Quote →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial Oshkosh jobs with written specs and a real timeline.
Request a Commercial Quote →Here's exactly what Oshkosh customers can expect from first call to final walkthrough.
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 Oshkosh quote is written before work starts, not estimated verbally and adjusted later.
You get documentation of the work plus a real warranty — not just a handshake.
We've heard every Oshkosh horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
There's no verbal quote that grows once the crew shows up — the written estimate is final.
A local dispatch model means the technician who answers your questions is the same one who shows up.
If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.
We'd rather earn a repeat Oshkosh 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.
Our trucks are recognizable around Oshkosh — 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."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
