We have had our home's windows cleaned with A1 about every 6 months for the past 3 years. (Three story house with lots of windows very high up!). Their prices are competitive, and they have always been consistently friendly, professional, and respectful of our home. They ALWAYS do an amazing job! Our last clean was on July 2nd, 2020, and their cleaners paid particular attention to social distancing while in our home, and also wore face masks, giving us great peace of mind. Another job very well done!
