Building Wash


Buildings need to stay clean, but each surface has a different tolerance for water pressure and chemical use. We closely inspect your building and recommend a combination of cleaning services that will safely get your property looking beautiful.

Low-Pressure Wash

Building exteriors can be safely washed at very low pressure settings—this preserves the surface while removing all superficial dirt, grime, and oil. Our technicians perform this service in conjunction with window cleaning to better manage overall project costs and avoid leaving water residue on window panes. After initial restoration, building curtain walls can be protected with a sealant to keep buildings looking attractive and new for longer periods of time.

Building Chemical Cleaning

Need to remove deeper building stains? We can do that with chemical cleaning. Stains from oxidation, mold, and debris on a building exterior need to be eliminated with a specialized chemicals. We pre-treat them with an environmentally-friendly solution, then rinse the solution with a pressure wash. To protect against future stains, we can apply a sealant after the wash is complete.
