We've known Mark since late 2011, when One Call Reno came to our house and gave us a live presentation of the energy efficient windows. We were impressed with the design and efficiency and decided to replace the old windows in the master bedroom and the dining room. Over the course of the next year and a half we had a chance to observe the efficiency across various seasons (winter vs. summer), and test the usability, both of which did not disappoint. We really liked them.
So, when the time had come for the second round of renovation, choosing One Call Reno was a no-brainer. Mark's team installed six windows and a patio door, to our satisfaction - quickly and professionally - all in one day. Quite pleased with One Call Reno's quality of work and the willingness to listen and adapt to our personal preferences, we had recommended the company to our close friends, who later hired and commended their work.
Based on the past experience, I would highly recommend Mark's team for any window renovation projects. In fact, I am going to follow my own advice and ask Mark to replace the remaining old windows in one of the bedrooms and in the office, as this winter has proved to be pretty cold.
