Mobile auto detailing and pressure washing, built one driveway at a time. Ripon, WI based and fully self-contained — we bring everything.
I’m Carson Hopp, 20 years old and originally from North Fond du Lac, WI. My detailing career started at a powersports dealership where I detailed cars and powersports equipment for them. I learned quickly that I could do better work on my own terms — so I started my own business on the side.
That business became Pristine Auto WI LLC. I ran it mobile at first, then built up enough to lease a shop at 434 E Oshkosh Street in Ripon and rebranded to 920 Detail Co. LLC. The shop was good — but being tied to a fixed location meant turning away customers who needed mobile service, and it added overhead that didn’t add value for clients.
So I went back to what worked: mobile. The business is now 920 Detailing & Pressure Washing — fully mobile, fully self-contained, and better than ever. I bring my own water, generator, and professional-grade equipment to your driveway. You don’t need to drop off the car. You don’t need to go anywhere. I come to you.
