"Window Wizards did an excellent job. They pressure washed my driveway, walkway, back patio, and also washed and cleaned my patio doors. Window Wizards was very professional and did a thorough job and I would definitely hire them again and refer them to others."

"Mario is an incredible businessman. He was quick to answer our requests, make sure that we had an appointment that fit our schedule, was early to the appointment, worked hard and did an incredible job. We used them for window cleaning but he had a multitude of services and I would not be hesitant using him for any one of them. A good man with a good business that does great work at a good price."

Window Cleaning FAQs, answered by experts

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.

Yes, you should plan on being home when a window cleaner is cleaning your windows. The professional will clean both sides of the glass and will likely disassemble parts of your windows from the inside to clean and inspect the inner components, including the balances and weatherstripping. Much of this work requires interior access to your home, which means someone will need to be home to provide access to the window cleaner.

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.

There are a few qualifying questions you can ask a professional window cleaner to help you decide if it’s the right company for you:

  • Does your price include the inside and outside of the windows?

  • Will you clean the tracks, rails, and other internal components?

  • Are you fully insured?

  • How many years of experience do you have?

  • What kind of cleaning products do you use?

  • Do you have any customer references?

  • Do you provide any other services, like exterior power washing?

All of the things you use to help you get clean can leave your shower door looking dirty. Water can leave mineral deposits as well as unsightly spots when drops of water dry on the glass. Soap and shampoo can cause build-up and residue that leaves a layer of soap scum in your shower, which then attracts dirt. Mold and mildew can also contribute to dirty shower doors; these fast-growing organisms thrive in areas with poor air circulation, damp conditions, and residue from things like soap and shampoo.
