I hired AAA Showcase Professional Window Cleaning, because of their claims of what a complete job, which included complete cleaning of window sills, screens, frame and windows. As they were finishing I went around and checks, I found that the window sills were not clean, they may have dusted, but not clean and some windows had places that were missed. When I show him the problem, he got mad and got a bucket of water and started to redo the ones I pointed out, splashing water all over and banging my new kitchen tops. I told him to stop and get out. I would never hire AAA Professional window cleaners, they are NOT PROFESSIONAL nor is their web site truthful. Very Bad Experience, the company consist of the owner and a helper. DO NOT USE THIS COMPANY, YOU WILL BE SORRY! Very Upset, in Van Nuys, CA
