"The front of my house was a green mess, Keith and Mary made my ten yr old gray siding & roof looked new. Made my 40 yr old garage roof look like a roof again. Very hard working and courteous on an extremely hot & humid day. Also cleaned my "green" fence back to white w/o me asking. Highly recommend & will use them again. Thanks for a hassle free job!"

Window Cleaning questions, answered by experts

Window cleaning depends on how the cleaning service defines their deep cleaning tasks, so pay attention to the details. You certainly should make sure window cleaning is included in the package. Some services will include it as an add-on, so you may have to pay extra. Find out if the cleaning includes interior windows only, or interior and exterior windows. Exterior windows may cost more.

Hard water stains are caused by hard water. Hard water contains a lot of minerals, like calcium and magnesium. When water on your glass surfaces dries out, the minerals stay behind and stick to the glass. This results in a residue that looks like white cloudy or streaky spots. Call a pro to install a water softener to banish hard water problems.

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.

The type of cleaning requested will change the total price you pay. Be sure to specify the type of cleaning you need when hiring a new cleaning service. Different approaches to cleaning change the price, such as:

  • Standard cleaning: $75–$175 per visit

  • Deep cleaning: $200–$400 per visit

  • Move-out cleaning: Up to $500

  • Event cleaning: $100–$500

One of the best professional cleaning solutions that won’t leave streaks is one gallon of distilled or bottled water mixed with 2 to 4 teaspoons of dish soap. Apply using a sponge in a figure-eight motion, and then use a squeegee to remove the majority of the water and soap. You can finish drying with a piece of old black-and-white newspaper to remove any residue for a streak-free clean every time.
