"Great communication and great job! I feel like when hiring any cleaning service, the first couple of cleans, the cleaning service crew and myself are getting used to each other. Any concerns I had I let Sirlei know and she took care of it efficiently. The cleaning job that they preform is great and detailed. They also are very good to my dog which is always a plus."

"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."

"I am so happy to have found Francesca and her team. They confirmed the evening before, came on time, and did an excellent and thorough clean. I try to keep up with the cleaning myself, but they bring it to the next level, including getting underneath furniture, wiping down the windows, and all the other corners and crannies that I have neglected for too long. My stove is spotless! It is a pleasure to have them come and leave our home sparkling. I am excited to have them coming regularly in the future."
