"In the past, I have cleaned my own windows. This is the first time I have used a professional window cleaner, and I was a little nervous about how the windows would turn out because Iâ  m pretty fussy. I am so pleased with Delâ  s Window Cleaning! They were easy to reach, responsive, punctual, professional, and they did a great job. Will definitely use them again. HIGHLY RECOMMEND."

Window Cleaning questions, answered by experts

Generally speaking, you should clean your windows and any associated fixtures and treatments every six months. Otherwise, clean them as needed to keep everything running smoothly. If you live in a part of the country with especially hard water, you may have to clean them three or four times per year, and the same goes for areas where insects, pollen, dirt, and other debris can soil your windows and potentially cause issues with the moving parts.

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.

Well water can leave ugly marks on your window. A vinegar-water spray will remove most well water stains from your windows. However, you can also use a baking soda paste if the stain is too stubborn. Consider applying waterproofing protection to the glass surface after cleaning for long-term protection. A protective film or spray layer also makes it easier to remove the water stains next time.
