Deca cleaning did a good job pressure washing my house and spraying off the cobblestone driveway. The people were all very friendly and they did a decent job, but for the price I paid I expected a bit more. Maybe my expectations were too high, but I do not feel as though I received fair value for the amount I paid. The roof and stones were washed down in just under an hour and the service tech was here and gone. It looks better, but only marginally better. I think if I were to have this cleaning done again I would search the classifieds and find another company that cost a bit less.
