Concrete Drill

When we built our concrete house, the last thing we wanted to do was drill a hole in the wall. We planned for all of the exterior penetrations and left appropriate blocking in place when the concrete was poured so that we could put the appropriate plumbing, wiring, or windows in place as needed. Fast forward eight years and our heat recovery ventilation unit is not adequately venting our bath humidity. We decided to install a direct vent fan in the bathroom. Yes, we had to drill a hole in the wall. Not we, HE had to drill a hole. Mindy was exhausted just watching Noah do the work (I think I held the hose or something!).
