About · Meet the owner

Started at 13 with a bike and a homemade trailer.

Olson Pro Wash is owner-operated by Ethan Olson — born and raised between Marysville and Lake Stevens, and never far from home since.

Our story

Born here. Built here. Still here.

My name is Ethan Olson, and I've never really lived anywhere else. I grew up between Marysville and Lake Stevens and graduated from Lake Stevens High School — the same streets I now run a work truck down every week.

I started young. At 13 I built a little trailer, bolted it to the back of my electric bike, and started mowing lawns around the neighborhood. It was a real business, just a small one — and it taught me the thing this whole company still runs on: people will hand you their home if you show up, do what you said, and treat it like it's your own.

At 16 I made it official — licensed, bonded and insured, done the right way. Around the same time we shifted the focus to exterior cleaning: pressure washing, roof and soft washing. Olson Pro Wash has been that ever since. Same owner. Same standard. A lot more equipment.

I love Snohomish County, and I love Washington — the evergreens, the lakes, the fact that everything grows moss if you leave it alone long enough. You'll catch me at just about every community event, at the Planet Fitness in Lake Stevens, training MMA, or on a ladder somewhere between here and King County. This is home, and these are my neighbors. That's not a marketing line — it's just the job.

What we stand for

Four rules we don't bend

Honest work

Straight scope, straight pricing, straight timelines. The number I quote is the number you pay.

Method over muscle

The right detergent and dwell time beat brute pressure every time — deeper clean, zero damage.

Show up like a pro

On time, in uniform, in a clean truck, with the paperwork you asked for. Every visit.

Leave it better

Landscaping protected, walkways rinsed, nothing left behind but a cleaner property.
