"We had quotes for window cleaning from several other companies, but this job was the least money by far from all the other quotes. Lawrence did an excellent job, and cleaned the windows inside and out, including the sills and screens. Our windows were extremely dirty and hadn't been cleaned since we moved in a year ago, because we live in a new development and there was new house construction going on all around us until this month when the other houses were finally finished and the lawns seeded. The construction dirt and blowing earth from bare ground had made the windows so filthy I didn't want to clean them myself. I have about 25 windows, and Lawrence was finished in about two and half hours. That job would have taken me a week! He was on time, polite and worked very fast."

"Dennis and Joel were professional, prompt, and hardworking. We had 10 years of grime to get through and they really helped make the place sparkle. Spent extra time thoroughly wiping all baseboards and baseboard heaters prior to carpet cleaning. Also deep cleaned kitchen/foyer tile and grout and even the garage floor! Looks like new. Will use them again for sure."

Window Cleaning questions, answered by experts

At least twice a year, but frequency depends on location and exposure to elements.

While clean windows don't automatically increase home value, they make your home look more attractive from the outside, and since the exterior is the first thing a potential buyer will see, it can help make a good first impression that paints the rest of your home in a positive light. Educated homebuyers will see that your home is well cared for if they see clean window tracks and sparkling window glass, which can contribute to an overall positive opinion of your property. Clean windows give the impression that the rest of the home—including systems and appliances—is probably well-kept, too.

The best time to clean the outside of your house is during your outdoor spring cleaning. Wait until late spring, after the wave of pollen is done coating your home. You can also wash your house in late fall–before the first freeze–to remove leaves and branches from the gutters.

Finding a quality professional window cleaning service is much like finding any other vetted home pro: You should ask friends and family members who you trust for recommendations for window washers in your area and check online ratings. Reading a company’s reviews will give you a lot of insight into the service you can expect. Then, check their credentials and contact them to get a quote. Be sure to ask questions about their process and the products they use to get your windows to shine.

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.
