Is a PSI pressure washer powerful enough to clean a deck and siding on a house? I want to prep my deck for painting and also want to wash the siding on the house. Thanks

Answer
â¢1500 through 1850 PSI â suggested best for cleaning decking, patios, sidewalks, or garage doors


â¢2000 through 3000 PSI â propose using this for cleaning larger decks, such as marina piers, siding, stucco, or fences

What kind of pressure washer should I rent to power wash a deck, and what will the approximate cost be?

Job Seeker

I've volunteered to pressure wash a friend's deck that is approximately 20' L X 8' W. I want to complete the job in one day since the house is 100 miles from my home and I'm only going to stay over one night. I know that pressure washers are rated by the number of PSI (pounds per square inch). Can anyone tell me how many PSI I should get in a rental? Is my hope to finish the job in one day realistic? The deck boards are pretty dirty due to lots of trees all around. Any other advice would be welcome.

Answer
In my opinion a 2000 to 2550 PSI unit would do the best job for you.
This would give you enough cleaning power to not be all day getting it done, and gentle enough to not rip the wood apart from extreme pressure.
Start on a surface not easily seen until you get used to the machine, and use straight even strokes slightly overlapping as not to streak the deck
