John Shanahan founded Lighthouse Window Cleaning, Inc. with a simple vision: provide dependable, high-quality service while building lasting relationships within the community. What began as a small side business in the Sacramento area has grown into one of the region’s trusted providers of commercial and residential window cleaning and exterior maintenance services.

 

Based in Rocklin, California, Lighthouse Window Cleaning serves commercial and residential clients throughout the greater Sacramento region, including office buildings, retail centers, restaurants, property management companies, and homeowners. Lighthouse Window Cleaning has built a strong reputation for professionalism, reliability, and attention to detail, offering services that include window cleaning, gutter cleaning, pressure washing, solar panel cleaning, dryer vent cleaning, high dusting, and exterior building maintenance.

John’s entrepreneurial journey began in 1996 while working in management roles with companies such as Starbucks, Chipotle, and REI. Cleaning windows initially started as a way to provide additional income for his growing family, but over time it developed into a passion for customer service and business ownership. In 2012, he made the decision to focus full-time on growing Lighthouse Window Cleaning into the respected company it is today.

 

Over the years, Lighthouse has become known not only for quality workmanship, but for its people-first culture and commitment to service. The company emphasizes professionalism, communication, and consistency while investing heavily in team development and long-term employee relationships. Many team members have been with the company for years, helping create a culture built on trust, accountability, and pride in the work.

 

Today, Lighthouse Window Cleaning continues to grow as a values-driven company focused on serving commercial and residential clients with care and excellence. The company’s mission extends beyond clean windows, striving to provide dependable service, create opportunities for its team, and make a positive impact throughout the communities it serves.
