I don't wear a tie...I feel the client is expecting me to explore every nook and cranny of the house, so they expect me to get at least a little dirty. I wear a Duluth Trading FOM button down shirt in steel blue with a pair of Carharrt six-pocket cargo pants. I have my shirts embroidered with my logo and my InterNACHI patch sewn on the sleeve. The shirt has a left and right chest pocket, a cell phone pocket above the chest pocket, and pencil slots on both sleeves. I use an Occidental Leather tool pouch with my flashlight, a mini maglite, a torpedo level, a moisture meter, a microwave test bar, an IR thermometer, Suretest recdeptacle tester, non-contact voltage tester, two lead test probe, compass, Ridgid 12V mini driver with various bits, a clean rag, a marble, a yellow and red lumber crayon, and another minimag flashlight. The rest of my stuff is in the truck.
