"Larry was extremely responsive! We had a tight turn-around timeframe as we were listing our house on the market in a few days and needed the windows deep cleaned. I called on a Friday and he squeezed us in the next day-Saturday! Other companies stated they had several week waiting lists and We have lived at our house for 10 years and except for a few wipes with Windex, the windows had not been deep cleaned. Larry and his assistant did an AMAZING job! The windows look brand-new! My husband was doubtful at first that it was worth the money- but he was astounded on how good they looked afterwards. Thank you so much to Larry! The realtor was thrilled with the results as were we.
