Who Shows Up

I'm Joe. It's My Name on the Truck.

I started Northwest Exterior Clean because every time I looked at a roof, a driveway, or a set of windows around here, I could see exactly what it should look like — and I knew most people would never get around to it themselves. Ladders, chemicals, a wet roof in March. It's not a fun Saturday.

So we do it. Properly, with the right equipment for each surface, and with the kind of follow-through you'd want from someone working on your own house. I'm on every job, along with Lucas, who's as careful about the work as I am. We quote it straight, we show up when we said we would, and if something isn't right, we come back.

What Customers Say

Reviews From Real Jobs

Straight from customers across North Idaho and the Inland Northwest.

★★★★★

“I opened my gym business in an abandoned auto shop, and the floors were covered with decades of soot and grease. Joey pressure washed the entire floor of the gym and got the concrete incredibly clean. The space had a terrible smell, and after he was done, it was completely gone. I couldn’t recommend Joey enough for pressure washing, window cleaning or any other outdoor job.”
