Do-it-yourself pressure washing may sound like fun, but it is time consuming, tedious, and often leads to damage from unskilled use. Our courteous, professional Black Diamond technicians give you incredible results with maximum efficiency.

We specialize in pressure washing driveways, walkways, patios, and decks. We don’t pressure wash roofs.

Driveways, patios, and decks can get dangerously slippery in our Pacific Northwest climate. An annual cleaning removes the layer of algae and makes the surface look brand new.

The quality of the work was excellent, ESPECIALLY the cleanup. I like having the roof cleaned by brush and air instead of power washing.

I was extremely happy with the power washing and the window cleaning work on our house.

roof and gutter maintenance is a package service they offer, including moss treatment; which is a good value and they do good work. Pressure washing was done very well; looks great.
