Matt installed a dryer vent, including cutting out a block glass window, in the winter of 2015. I found him through a recommendation from a neighbor and would definitely recommend to others. It was easy to schedule, he was great with email and phone communication, and gave us a reasonable price. He even emailed a few weeks later to make sure it was working out okay, since he had to use a different product than usual due to the extremely cold temperatures. It was a really small job, but he put a lot of care into making sure the work was done right and looked neat and professional. We would definitely use him again.
