"They did a great job. We have a lot of windows and storm windows and they were very thorough. The entire job took most of the day and Kevin's crew stayed at it until it was all done. When we walked through afterwards, Kevin had the crew make corrections and adjustments immediatelly. I will use All Clean again."
