Floor Waxing & Polishing Service

100% Customer Satisfaction Guaranteed! This is why we are a Golden Star janitorial company.

Polished floors give your customers and visitors an inviting welcome and immediately show the professionalism of your business. You have invested a great deal in giving your business a stylish and modern appearance, and maintaining that appearance is just as important. We provide floor polishing and waxing in Ontario, California, and the surrounding areas to give your floors that like-new shine. With regularly scheduled cleaning, your tile, marble, linoleum, granite, and concrete floors will look shiny and clean at all times.

Over time as employees, customers, and visitors go about their daily activities; they deposit dirt, dust, scuff marks, and more on the floors. Floors in high-traffic areas like bathrooms, kitchen areas, and lobbies are particularly susceptible. They lose their shine, becoming dingy, dirty, and even sticky. Floor polishing eliminates this worn-out appearance and makes floors look new again, renewing the vibrant color of the floor and scrubbing away the dirt on top. Whatever state your floors are in, we can get them polished and clean. Floor polishing and waxing can be used for large and small spaces at any time, whether you have just moved into a new workspace and you are looking for a new look or you are looking for scheduled cleaning to keep the space looking shiny and new each week.

Call Golden Star Janitorial For Superior Window Cleaning in Ontario

100% Customer Satisfaction Guaranteed! This is why we are a Golden Star janitorial company.

When you're trying to impress customers, clients, and other VIPs, aesthetics matter. You're going to be judged on every aspect of the presentation of your business, and your indoor standards of cleanliness are part of that presentation. If a visitor comes to your place of business and notices your windows are dirty and grimy, that's going to reflect badly on your operation.

Of course, aesthetics aren't the only consideration. Windows that go too long without washing and cleaning are more likely to become damaged and have that damage go unnoticed. Poor maintenance can reduce the lifespan of your office or building and reduce its property value as well.

Professional window cleaning isn't expensive and only needs to be done a couple of times a year, making it an easy investment for any business.

Golden Star Janitorial Inc offers high-quality window washing at affordable prices! We've been providing janitorial services to the Ontario, California, area since 1999 – and we have plenty of satisfied customers who love the results! We have the skills and expertise to keep your windows bright and attractive year-round.

We have water brooms and high-powered pressure washers, which are highly effective in cleaning windows, as well as high-grade cleaning chemicals.
