"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

Prices vary depending on window size, building height, and accessibility, ranging from $5 to $15 per window or $150 to $500 per service.

In most cases, you should get your windows cleaned one to two times annually, although you might want to complete this task more often if you live in an area with heavy pollen or heavy rain or snowfall that soils your windows. It’s also a good idea to hire a professional window cleaning service if you’re listing your property, as sparkling windows will make a big difference in terms of curb appeal and, potentially, your home’s value.

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

The best way to clean outside windows is by using a garden hose. Start by spraying the windows with a high-pressure stream to clear off loose dirt and grime. Then use a mixture of hot water and dish soap and scrub the windows with a sponge. Rinse off the soapy water with the hose. Before you finish up, spray the windows with a solution of vinegar and water and wipe them down with a microfiber cloth.

Cleaning services typically offer a range of options. Some of the most common cleaning tasks include:

  • Windows: $4–$10 per window

  • Refrigerator cleaning: $10–$40

  • Carpet cleaning: $75–$200

  • Baseboard cleaning: $25–$75

  • Laundry: $5–$20 per load

  • Cabinets: $20–$50

  • Polishing or waxing floors: $25–$50

  • Dusting: $10–$30

  • Oven cleaning: $20–$40
