I live in an old house and everything seemed to go wrong at once! John sorted out all my problems over the course of 2 visits: he repaired three faulty light fixtures which had sporadically kept us in the dark for 6 months, replaced a bathroom fan (which he kindly picked up for me at the hardware store), and removed a sensor light so we could have the lights on in the backyard without waving our arms madly at the sensor. As an added bonus, John also gave me a training lesson for our new puppy! Thanks, John!
