Water Pressure Cleaning
The other day as I drove by the neighbors house I notice he was having it cleaned so I stopped by to see him. I walked up to him as he was watching the water pressure cleaning crew he had hired. I asked him what cleaning company it was and he said it was just a few guys he knew from work.
He claimed there was not much to water pressure cleaning and that anybody could do it. Just then one of the window screens popped out from a second story window and crashed into the bushes. Apparently they were using quite a bit of pressure.
He assured me that you need that much pressure to get it clean. Well about a two months later I saw a vinyl siding crew there repairing some damage and a mold redemption company killing mold in the outside walls caused by water damage. It seems that high pressure is not the proper way. Low pressure and the correct cleaners is the proper way to clean a house.
