"Rudy and his team were great! Quoted me price, some windows required additional work but kept the agreed upon price. Rudy and the team arrived right on time and finished exactly when they estimated. Very nice and respectful crew, always important with kids in the house. Windows look like new! Highly recommend!"

Window Cleaning FAQs, answered by experts

A handy hair dryer will quickly remove condensation from your window, but it’s only a temporary fix. The hair dryer maneuver will not repair the root of the window fogging problem, which is likely a broken window seal. If you need to defog the window quickly, such as if guests are coming over, use the hair dryer. However, for a permanent solution, defogging the window or replacing it are the only options.

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.

Deep cleaning after a renovation is important to remove all the dust from construction. This will improve air quality, prevent health issues and increase the home’s comfort level. Also, debris and dust can stain new paint or scratch surfaces, ruining the renovation right from the get-go.

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.

Whether you’re a renter or a buyer, you should clean a house when moving out. For renters, it’s usually written in the lease that a house must be cleaned before it’s vacated. If you’re unsure how thoroughly to clean the place, check with the landlord beforehand; otherwise, you may not receive your deposit back. When selling a house, a contractual agreement is often made with the realtor that the house is swept and that all personal belongings are removed before the previous owners move out.
