Professional from start to finish. The office always calls back promptly and arranges a time that is convenient for me. The window cleaners do a great job on the windows and they are also very careful of my home - no puddles of water are left behind, the window sills are always clean and dry, and the screens are carefully removed and replaced. I've been using Paul's Window Washing regularly for 10 years and have always been satsified. I will continue using this company and would recommend it to anyone that needs windows cleaned. The prices are affordable also. Great company!
