"Our windows were in such bad shape that a simple cleaning wouldn't have made a difference. Rudy actually did a restoration on them by using a special compound and they now look amazing. The windows are crystal clear and look brand new. Rudy and Michael did a great job and were punctual and extremely courteous; the price was excellent. We can highly recommend this company."

"The 2 workers went above and beyond. Made a badly stained and mildewed awning look brand new. Keith also fixed 2 door screens that had been pushed out by my grandchildren and my dog by accident. I did not ask he just did it. And Mary came back in the house to look into a smudge in a window that I look out of all the time. No attitude, just happy to take care of it. Very pleasant to have around. Had no qualms over having them in my house. Ron, you have a great crew."

Window Cleaning questions, answered by experts

Professionals use HEPA vacuums, industrial-strength cleaners, and microfiber cloths for effective cleaning without damaging surfaces.

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.

Professional house cleaners may use a variety of cleaning products, but a great option is a cleaning solution containing ammonia or white vinegar, water, and several tablespoons of dishwashing liquid.

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.

Clean high-traffic areas such as kitchen surfaces, bathroom surfaces, and bedding once per week. Deep clean other areas every three months to a year. How you use a space can help you figure out how often it should be cleaned, with areas where eating, bathing, and food prep occur getting the most frequent attention.
