Premium PowerWash
We're Premium PowerWash, a locally owned and family-run exterior cleaning company based in Portland, Oregon. Founded in 2021 by brothers Dimitri and Alec, we specialize in safe, low-pressure roof moss removal and complete exterior cleaning for homes and commercial properties across the Portland metro area. Our focus is soft wash roof cleaning: a gentle, low-pressure process that clears moss, algae, and lichen without cracking tiles or stripping shingles, so your roof looks better and lasts longer. Beyond the roof, we handle gutter cleaning, house washing, pressure washing for driveways and patios, window cleaning, tile roof cleaning, and roof treatment designed to slow moss regrowth in Portland's damp climate. We also take on commercial exterior cleaning tailored to each property. When you hire us, you work directly with an owner rather than a subcontractor. That hands-on approach is a big part of why homeowners trust us, and it shows in our 5-star Google rating from more than 100 reviews. We back our roof work with a written 12-month guarantee: if moss visibly regrows on any area we treated within a year, we come back and re-treat it at no charge. We serve Portland and surrounding communities including Beaverton, Tigard, Lake Oswego, Gresham, Oregon City, Tualatin, West Linn, Wilsonville, Happy Valley, and Vancouver, WA. Getting started is easy: use our instant online estimate tool to see pricing based on your property, with no obligation to schedule. And when you book a roof cleaning, gutter cleaning comes complimentary. Reach out anytime to confirm coverage and get on the calendar.
