I called Patrick to see if he could help with an old hidden flexible white plastic dryer vent hose. The vent ran behind the wall and in the finished basement ceiling, making a number of turns, and was completely enclosed. Patrick replaced the vent with metallic vent pipe, doing little damage in the process. He also replaced the outside vent cover, which was badly damaged (replacing my old bathroom vent cover at the same time). Patrick was knowledgable, neat, and very nice professional. I highly recommend his services. Thanks Pat.
