Commercial Pressure Washing in Portland, OR

Portland's commercial exteriors take a beating through the long wet season — October to May of tracked-in soil, algae growth on concrete, oil deposits in parking areas, and grime on building faces. Strong Tower's commercial pressure washing keeps Portland properties clean and safe year-round.

Portland's Pearl District and Lloyd District commercial walkways sit above the city's older storm-drain infrastructure; organic debris from street trees and heavy pedestrian traffic combines with clay-heavy runoff to create the kind of biological surface growth that standard power washing can't fully clear without the right technique.

Portland's wet season produces the highest algae and mildew growth rates in the region for north-facing concrete and covered canopies — a spring pressure wash after the rains clear is the most cost-effective single visit to schedule at a Portland commercial property.

Strong Tower has pressure-washed building faces, walkways, and parking areas at Portland commercial properties from inner SE to the Lloyd District since 2012, working around city parking requirements and building management access protocols.
