Last week The Roof Wizard's Crews softwashed our largest project year to date. I bid the job back in April, and after consistent follow up, they called me the Tuesday before Thanksgiving and gave me the PO. The only stipulation was that it had to be done before Thanksgiving, because they are going to be putting a sealer on the entire building, as soon as we finish. The project was just under 100,000 SF of limestone, 16,000 SF of equipment screen and 12,000 SF of sidewalks. We also cleaned all the exterior windows and skylights using DI water and poles. We jumped on it Monday morning and wrapped up, in the dark on Wednesday night. The temps never reached 50 degrees the entire job and every morning we started spraying when it was around 27 degrees. At one point, the hose reels froze and the mix was actually freezing to the building and flaking off as snow. It took us three days with three crews working every hour we could, and we finished on schedule. We used just over 700 gallons of SH and two and half cases of pixie dust. 

Only downside was the deer I hit on the way home Wednesday night, that wrecked the front end of my truck. It also went under the 40' lift I was towing and almost made it jump the hitch.
