Impressions Concrete did a great job on our back patio. We were unfamiliar with stamped concrete and discovered Impressions at the home show in Ottawa. We received a few quotes and impressions seemed very competent, knowledgeable, and friendly. They were also very prompt with their quotes and answers to our questions. We picked out a natural gray seamless stone pattern which we love! There is no maintenance and no weeds to pull out from the patio. The job was done in a few days and there was no mess left behind. The crew on site were very polite, hard working and courteous. We were able to use our patio right away and have been enjoying it all summer.
