"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

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.

You should avoid using abrasive materials and harsh chemicals when cleaning windows. Abrasive tools like scrubbing pads, rough cloths, or steel wool can permanently scratch and damage the glass. Harsh chemical cleaners containing alcohol or ammonia can damage window treatments, frame materials, and special features like tinting. It is also best to use distilled or filtered water instead of hard water, which can leave spots or streaks. For best results, use a clean microfiber cloth to wash the glass and old black and white newspapers to dry it without leaving streaks.

Yes, WD-40 can remove stickers from glass thanks to its chemical properties that can break down adhesives. Be sure to wear protective gloves when handling WD-40. Spray the window or glass item, and let it sit for 10 minutes before scraping it with a plastic scraper or credit card.

Use of harnesses and ladders ensures safe roof access.

Clean with non-abrasive cleaners and a soft cloth, avoiding ammonia-based products that can degrade the film.
