Maybe you like the rugged look and sport a little bit of stubble on your face.  Or still have those earrings from high school.  Perhaps your girlfriend told you she likes guys with long hair.

I've observed numerous service plumbers who would 'let themselves go'.  They were also the ones who would go home early, were hanging out at the shop, and leeching off of others for work.  Why is that?  Read below to find out.

Working for a professional company, you need to present a professional look.  Some companies may have looser policies than other, and the following list is nothing more than guidelines.

Keep Your Hair Short
Unless your clientele is 100% people who have long hair, this is a must.  Dealing with anyone from an older generation expects that you have short, groomed hair.
This is not to say that it needs to be buzzed down like a crewcut, so long as it stays out of your eyes, and is clean.

Have a Shower
Every day.  Every morning before you leave for work.

Shave
Unless you have a very special reason not to, keep your face clean-shaven at all times.  It exudes a professionalism that will help you build trust with your customers.

Clean Uniform
Don't keep putting on the same uniform every day.  A good policy here is to have one on, one in the wash, and one in the drawer.  I also keep a spare uniform in my truck, just because you never know what you're going to get yourself into with some calls.

Wear a Belt
It will help prevent plumber's crack.

Wash Your Boots
More of a courtesy to your customers.  You don't want to be dragging in the mess from your last job into their home.
