"They did a wonderful job cleaning all of the windows, inside and out. They also cleaned several large mirrors inside my home, as well as two French doors. They arrived on time and ready to work, and were both friendly and professional. The cost was reasonable as well. I plan on having them return to do my windows regularly!"
Gleaming clean!

"Kevin does the best job ever. He always has a smile on his face and he takes care of our belongings. We have him clean windows annually, solar panels, gutters, moss treat our roof, pressure wash our concrete and seal it all when needed. He also hangs our holiday lights annually. We won’t use anyone else for any of these services."

"Ray’s Pressure Washing made my driveway and patio very clean. The cleaning for both areas took less than an hour and the service cost a very reasonable price. I would not only hire this business again but would also recommend to anyone who needs a driveway washed."

"I am the president of a small homeowners association in Southeast Portland. I had called a few companies to get three quotes I must say that your company was the most competitive and willing to work within our budget! You presented a very professional outline of what services would be performed and when you left, the entire area was spotless! Your service is excellent and very professional! I would rehire your company again in a heartbeat! Thank you!"

Window Cleaning FAQs, answered by experts

For a standard 1,000-square-foot home, you should expect your window cleaner to take between 1 and 3 hours to clean all of your windows. Of course, the size of your home and the number and size of the windows you have will play a role in the timeline. Certain styles of windows—like picture windows, which have no moving parts—also take less time to clean.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

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.

Yes, professional window cleaning is worth the investment. Regular deep cleanings help keep your windows looking new, extend their lifespan, and boost your home's curb appeal. By removing dirt, dust, and other debris, you can reduce the risk of damage and accelerated wear to window frames and components. It also improves your home’s energy efficiency by keeping insulation and weatherstripping in good working order, potentially lowering your energy bills. Furthermore, annual or bi-annual cleanings can help identify problems like leaks or cracks early, before they escalate into expensive water damage. You can often recuperate the cost of cleaning through energy savings and by avoiding premature window replacement.

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.
