"Dear Patrick and Mary, What a beautiful difference the blinds over my sliding glass door in the bedroom have made. With your attention to detail and knowledge of texture, color, and . . ."

"He is very pleasant. He is very business like. He comes exactly when he says he is going to. The shutters are beautifully made. His office personnel are great. The person who deals with his telephone calls returns calls promptly . . ."

I had dark brown stained shutters in my house and wanted to lighten up the look. Patrick came to look at them and said he could paint them white. They are now a beautiful white and look brand new. Patrick was so nice and even bore up to my insecurities about the shade of white. Mary, who takes care of the office was incredibly sweet. I would recommend this company highly.
