"They were great. Definitely worked hard and the house looks great. I hired them for a deep cleaning after renovations so I paid more than their asking price. They was constantly working and because of the amount of dirt from the renovations it took 5 hours to complete. I will be having them back."

Window Cleaning FAQs, answered by experts

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.

One of the best professional cleaning solutions that won’t leave streaks is one gallon of distilled or bottled water mixed with 2 to 4 teaspoons of dish soap. Apply using a sponge in a figure-eight motion, and then use a squeegee to remove the majority of the water and soap. You can finish drying with a piece of old black-and-white newspaper to remove any residue for a streak-free clean every time.

Yes, you can create a solution of dish soap and hot water to create a cleaning solution. You’ll want to mix about one to two drops of dish soap for every 8 ounces of hot water. If you use too much soap, it’ll create too many suds and make it harder to effectively wash away.

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.

You can use a commercial water repellent treatment for glass on your shower doors to prevent water spots. Take care to only apply the product to glass. Letting air circulate also helps prevent water spots, as water is less likely to remain on the glass for a long time with good air circulation. Run your vent fan, open a window, and leave the shower door open for about half an hour after using the shower.
