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.
Our Oshkosh crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
Our Oshkosh 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.

📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Oshkosh crews hear about most.
A musty smell usually means moisture is already moving through your Oshkosh basement, even if the floor looks bone dry.
Stair-step cracking in block foundations is one of the most common early signs our Oshkosh crews see.
Efflorescence is a reliable early sign that water is moving through your Oshkosh foundation wall right now.
A pump under constant strain tends to fail during the exact storm that needs it most.
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.
A flooded Oshkosh basement doesn't wait for morning, and neither do we. Our crews get it out and start drying the space the same visit.
Get Emergency Help →Seasonal ground movement in Oshkosh 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 Oshkosh after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
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 →Older Oshkosh homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.
Get a Crawl Space Quote →We can phase larger Oshkosh commercial projects around business hours or tenant schedules so operations keep running.

We photograph the damage and provide a written scope your insurance adjuster can actually use.
Word of mouth is still how most Oshkosh 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."
"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."
"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."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"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."
