Chris was very responsive over WhatsApp. He provided me with a very competitive quote straight away. He was able to do the date we requested. He arrived early and he and his wife did an amazing job on our windows. They hadn't been cleaned for years and they are now so clean they look like they are open. Chris made sure to work around furniture and cover things to make sure they didn't get wet or dirty. I would absolutely hire Chris again and definitely recommend him to anyone who wants a reliable and highly skilled window cleaner.Verified reviewerJob location: SW710 CLEANING WINDOWS INSIDE AND OUTSIDE
