"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 FAQs, answered by experts

Yes, in most cases, you can add a few drops of Dawn to a spray bottle full of vinegar to remove hard water stains. This solution can be used on your dishes, or you can use it in your shower, bathtub, or sink to get rid of hard minerals. Simply combine the ingredients, shake them up, then spray the solution onto limescale-ridden surfaces. Wait around an hour and then scrub the surface down.

Yes, many professional companies offer high-rise window cleaning using specialized equipment and safety harnesses.

Smoke stains, grease buildup, mold, and water spots are common reasons for hiring professional cleaning services.

The easiest way to remove window decals is to soak the area in hot, soapy water. Let it sit for 15 minutes before scraping it with a plastic scraper or the edge of a credit card. You can also remove window decals with white vinegar, rubbing alcohol, or applying heat from a hairdryer or steam cleaner.

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.
