 Trustindex verifies that the original source of the review is Google. Cleaning team was right on time. They explained what they were going to do and were done in about 1.5hrs.  The windows look clean and they cleaned up after themselves

 Trustindex verifies that the original source of the review is Google. Keenwick did a fantastic job cleaning our windows, sills and screens inside and out! The estimate and scheduling was seamless and the cleaners were fast, courteous and efficient. The price was very reasonable. I would highly recommend.
