I could not believe the difference in my house after Henry came. This is not your average pressure washing. Their process is detergent-based,and they truly cleaned our house. We were afraid that after having it washed, we would have light spots in the paint and be forced to have the exterior painted. That did not happen at all. Our house looks like it was just painted. They were here less than 2 hours, but the difference is incredible. I would highly recommend Henry to anyone. Their pricing is a little higher than traditional pressure washing, but you get what you pay for. I could not be more pleased!
