I am outright IMPRESSED and GRATEFUL with Vincent and Giovanni! The quotes I got from others because I have so many windows BUT also very tall windows and some closer to the roof were ridiculously expensive...Then I found Twenty20. First, just their phone manners made me decide to hire them: professional, understanding the importance of communication - informing me of their timing via text, etc; secondly what impressed me most is their professionalism and courteousness in person, REFRESHING I say! Finally, I have had my windows cleaned by others in the past, but NOT like this - my screens, my windows - inside/out - my large patio glass windows and the contours of them all SHINE like never before! I will be using Twenty20's services yearly without any hesitation!
