On March 9, 2020 we had D and D Clean Exteriors Ltd. clean moss off roof, which included hydrogen peroxide treatment, power washed 2000 sq. Feet of cement , washed house and shop, vacuumed inside gutters and washed outside and skylights, , cleaned windows. I am very pleased with the results, my windows have never been this clean, always had a film on them. They worked very hard to make them shiny, three treatments done, It has been years when some of this was done so they had the work cut out for them. They came at 9:30 and left at 6:00.
They had two trucks and three men.
