Boulder & Denver's Best Window Cleaning Company

Since 1978, Sonlight Window Cleaning has been a family-owned and operated business. While our services are located in the Boulder Denver-metro area and cater to countless neighborhoods ranging from the Highlands to Arvada, Mapleton Hill to Commerce City. Over the years, our window washing crews and owners have changed but our promise has remained the same; offering our employees an exceptional workplace that produces excellence in window cleaning. As a Boulder Denver business, we strive to make ever customer’s experience the best.

With many of our crew members living in areas like Boulder, Arvada, Northeast Denver, East Denver, Capitol Hill, Thornton and Wheat Ridge, we serve the same neighborhoods we live in and we are proud of the service we offer. Our goal is to not only provide you the best cleaning but also to provide you a memorable experience that tailors to your needs. With anything from customizing appointment needs to meet your schedule to working to address your specific questions about pricing and process, our crews are here to offer you the best experience possible. When you join our list of customers, you aren’t just hiring a company, you are joining a family.
