We are extremely pleased with our choice to use M&M Professional Window Cleaners to clean the exterior windows of our house. Mike was professional and pleasant from first contact right through to end. He quoted fairly, was flexible with scheduling, let me know when he was on his way the day of our appointment and arrived on time. He was very well prepared, respectful of our house and property and did a fantastic job! We highly recommend M&M Professional Window Cleaners and will definitely be using them again for all of our window cleaning needs!
