"I have had window cleaners in the past, however, the experience with Braeden, was far above any other window cleaner I have worked with. He was on time and very polite. I was really impressed with his professionalism and the care he took in cleaning the windows. The windows and screens were sparkling when he completed the job. I would highly recommend Braeden to clean your windows."

"Matt and his hard working team cleaned all our windows, screens, tracks, etc. In pre for a wedding we hosted at our home. They did an outstanding job, we're very conscientious and efficient. They're customized water pH system was interesting and efficient, allowed for streakless drying. Thier cost was reasonable for all the work it took to complete our home (~ 50 panes). Matt and his team were super nice. Several of our neighbors are planning to hire them. I highly recommend Shine for your window cleaning services."

Window Cleaning questions, answered by experts

Clean with non-abrasive cleaners and a soft cloth, avoiding ammonia-based products that can degrade the film.

It depends on the company and the services it provides. If a cleaning company is just washing the outside of the windows, the pro may only wash the glass panes. But if they’re washing the inside and outside, they most likely bundle cleaning the sill and frame into the cost. It’s best to ask before you schedule a service to see if the company will charge additional fees.

Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.

Professionals clean window screens the same way a homeowner can—by removing the screens and cleaning them with a sponge. A window cleaning pro may come with better equipment, like a high powered wet/dry vacuum or pressure washer to speed up the process and achieve a deeper clean.

Access to professional tools ensures streak-free finishes and safety in hard-to-reach areas.
