"Matt and his hard working team cleaned all our windows, screens, tracks, etc. In pre for a wedding we hosted at our home. They did an outstanding job, we're very conscientious and efficient. They're customized water pH system was interesting and efficient, allowed for streakless drying. Thier cost was reasonable for all the work it took to complete our home (~ 50 panes). Matt and his team were super nice. Several of our neighbors are planning to hire them. I highly recommend Shine for your window cleaning services."

Window Cleaning FAQs, answered by experts

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, but professionals use specialized equipment and cleaning solutions to safely achieve streak-free, long-lasting results.

Whether you’re a renter or a buyer, you should clean a house when moving out. For renters, it’s usually written in the lease that a house must be cleaned before it’s vacated. If you’re unsure how thoroughly to clean the place, check with the landlord beforehand; otherwise, you may not receive your deposit back. When selling a house, a contractual agreement is often made with the realtor that the house is swept and that all personal belongings are removed before the previous owners move out.

Costs depend on window count, height, accessibility, labor, and whether interior and exterior cleaning is required.

Clean the outside of your home at least once a year. If you live in an area with salty sea air, high levels of pollen, or an abundance of leaves in the fall, it's helpful to wash it at least two times a year. Frequent cleanings will allow you to remove debris and pests before they flourish into infestations, or cause mold and mildew.
