I've never been so happy with the OUTSTANDING SERVICE I received from Mark Portner and AJ! My experience started with a professional and immediate response to my request for a quote. AJ came out to our home and took careful review of our windows prior to cleaning. We have a Great Room with a 23 foot ceiling and the top window is 22 feet high. Not only did AJ get up there with his ladder, he was careful and very respectful of our home.AJ arrived on time, was mindful of removing his shoes and cleaned each room as he finished the windows.Again, I cannot recommend Dutch Clean's window washing highly enough. You will be THRILLED! I have told AJ he is stuck with me for life! I intend to take their business card to all of my neighbors to share how OUTSTANDING their service was!You will thank me if you hire Mark Portner and AJ. The pricing was very fair and the attention to detail can't be beat!I am a fan and customer for life!Can you tell I'm THRILLED?!
