What Our Customers Are Saying

Responsiveness, Punctuality, Quality, Professionalism, Value
I was impressed when I got an immediate bid from Mark at Window King. We needed the windows done quickly and he was able to accommodate us and at a good price. On the day of the cleaning, led by Kyle, he and his team did a great job on washing the inside and outside of our windows and our screens. They were friendly, professional and our windows turned out squeaky clean! In fact, we plan to use them to clean our gutters this month and hang our Christmas lights as well. Thanks Mark, Kyle and team!

I just used Window King for the first time and was most impressed with their professionalism and attention to detail. The guys left my windows spotless and were incredibly quiet and considerate of which we needed, because I had a sick child inside of which I had contacted them about. I highly recommend Window King!!

Great prompt service! Quick with a quote and did a fantastic job on our very old and complicated storm windows and screens. We attempted to get a cleaning done all summer from two other services and Window King delivered on our time frame and then some!

Tanner and Konstantinos were hard workers, meticulous and a conscientious. They were flexible with times and dates and came back to finish the job when I had to make other arrangements. I have been using Window King since the beginning and couldn't be happier with their service.

Window King has been keeping my windows clean and shiny for the last four seasons. The service pros are efficient and friendly. They are careful when cleaning windows not to disturb window treatments, as well as shoe protectors to keep from tracking in debris. I highly recommend this company.

Mark ( the owner ) answered the phone when I reached out for help and responded immediately. Mark was genuinely interested in understanding my needs and eager to meet them. He sent one of his work crews within an hour . His team ( Elliot and Jack ) were prompt, professional, efficient and respectful. They did a great job on some difficult windows. I will use them again without hesitance and with confidence that the job will be done and done well. This company is good at what they do and equally good at who they are.
