Here is a video of a power washing package deal we did yesterday in Silver Spring Maryland. In the deal we did a roof cleaning front and back, she had a shed in the back yard, we soft washed the roof on that also. We cleaned her gutter guard so it would continue to work like it is supposed to, we washed and waxed her home, and the shed in back also. We also power washed her concrete patio in the back, and we power washed her concrete sidewalk and power washed her concrete driveway also! Her sidewalk had some really strong algae in one section. After treating and dwelling and power washing, we had to do this a few times to remove all of it. We did all of this in less than 4 hours.
