Combine the need for construction with the time of year during a tough economy and it's easy to see why thousands of Floridians fall victim to illegal contractors.

Many have the truck, the tools and the price that will blow out the competition. But the downsides are often impossible to repair.

Some will steal deposits and never do the work.

"Many of our victims have given up as much as a 50 percent deposit," said Broward Sheriff's Office Detective Danny Belyeu.

Belyeu also said unlicensed contractors sometimes show up and do some work, but the outcome could be worse than a financial hit.

"Unfortunately, some of the things they do might have life-safety issues," said Belyeu.

To protect yourself, ask for a contractor's license number. Also, make sure it is printed on any working truck. By law, they are required to do so.

Be careful with handing over large deposits and never do so in cash. Question any deposit more than 10 percent.

Write checks to companies and not to individuals. Lastly, cheaper doesn't mean better. Remember that it costs money to operate a legal business.

"Along with a license, you're required to maintain and keep proper insurance, so there is a cost factor," said Belyeu.
