The company did excellent work supplying and installing shower film and supplying and installing blinds in the dining room and kitchen. Two of the company's two installers came out and were very neat and tidy. They installed the blinds and shower film in less than three hours. They were very open to comments and returned the following day to fix the valances above two of the blinds so the edges lined up perfectly. Moreover, the company pointed out when I accidentally paid the wrong (higher) invoice. How many companies would do that?? I truly appreciated it. I would definitely use ProMark again. Thank you ProMark!
