Kris cleaned our windows to an outstanding standard - they look brand new again! He also cleared our gutters and sent me before and after photos so I could see the difference.

It was the first time that I have used KM window cleaning and I highly recommend them. Chris is friendly and professional .I live on the 3rd floor so cleaning windows is a challenge. Most cleaning services use a extended pole to clean ,but Chris was able to clean both sides inside my flat. My windows are sparkling and they have never been cleaned to such a excellent standard.Verified reviewerJob location: SW19- MMarta P

Job location: SW18My first floor windows needed cleaning for a long time. Chris arrived on time and informed me several times a day about his situation - he is very communicative. She's very attentive to my comfort. She remembers everything important. She puts on shoe covers, protects the carpet, and vacuums after herself. The best window cleaner in London!!
