After a year or so in the Northwest weather mildew is pretty brutal in Oregon. This patio was a side pen for a couple of dogs. As you can imagine is was pretty dirty. Our pressure washing techniques made this job
move pretty quickly and the homeowner was very pleased with the results.
Our current residential setup is a Landa Northwest 6 gallon per minute pressure washer with a Landa Water Jet surface cleaner. Total time for pressure washing this area was about 10 minutes plus cleanup.
