If you find yourself with a household  job that needs to be done, you may be tempted to try and attempt the job yourself, in order to save you some time and money. However, even the smallest repair job can prove to be quite dangerous if not done correctly. While you may be able to do simple things like change a faucet or swap out light-bulbs, unless you are a professional, there are some jobs best left for those who are certified in their craft. 

Plumbing Repairs

Replacing a faucet is one thing (provided that there isn't extensive extra work involved), water is a force that should not be reckoned with. The smallest leak can cost thousands of dollars in damages, so messing around with your plumbing components is definitely something you'd want to leave to the experts. You can get into trouble when you start to modify your plumbing system, or try to diagnose the problem yourself. 

Working with hot water lines, for example will require the use of a blow torch. Unless you are an experienced welder, is that something you're willing to chance just to save some money on hiring a professional? Pluming problems can get out of hand relatively quickly, so call your local plumber when you know your problem is quite serious.

Electrical Repairs

Any home improvement project that involves electricity requires caution. While you can probably switch out an electrical plate or change a light switch, you're better off calling a professional electrician.In many cases, electrical work requires you to have a permit, and this is something you cannot obtain without the services of a professional. There are also building codes that may come into play, and again that's not something that can be handled by anyone other than a licensed professional. Not to mention  just one wrong move when doing the work could result in major damage or even severe injury. Take the right move and call in a professional electrician (such as one from Bader Mechanical Inc) for your major electrical work and repairs.

Gas Appliance Repairs

You may have a few different appliances that run on gas, but if you don't know how to deal with gas when your appliance is in need of repairs, it's best to call in a professional. Just as with water, gas can find a way to leak inside your home, and the ramifications are deadly. Even if it's just a swap out of an old appliance for a new, it's best to call in a repair specialist trained to work with gas lines, in order to ensure that the transition is done correctly.
