Welcome to APEX Exterior Cleaning, formerly known as Imperial Power Washing! We are a family-owned and -operated business with almost 20 years of experience. We are located in Richland, but service customers all over the Northwestern United States. We specialize in power washing for commercial, residential, and industrial customers. Our services include exterior cleaning and restoration for concrete, homefronts, windows, roofs, gutters, and more! We even offers a soft-washing service, a special system for more sensitive materials. Don't forget about your solar panels, as those need cleaning, too! Our unique hose can filter out impurities and hard water through reverse osmosis to ensure optimal results.
