We want to express our appreciation to Calvin DeHoff-- proprietor of PRO WASH 814-- and commend him for a thorough and complete all-house wash.The white trim, fascia, and gutters of our two story brick house with attached garage and sun room had accumulated 25+ years of gutter over-runs, leaf discoloration and shingle roof runoff. There was also metallic residue staining on the bricks from window screens and metal window frames. Calvin recommended a whole house wash to avoid streaking of the many windows, several doors, and bricks. He first tested and then used an extra treatment to remove the metallic residue. In addition, he examined and recommended a similar approach to a detached garden house. The whole process, including treating the metallic staining took approximately five hours on a 50 degree plus day two days ago. The house and garden house were immaculate after the job was completed. We are still impressed with the results that look like the exterior when newly built. Calvin is a knowledgeable, informed, honest, and courteous professional and a quality driven craftsman.
