If you have proven skills in almost any area of construction, you are in demand. Don’t think however that painting your own house or building a few pieces of wooden furniture will make you a skilled construction worker or make it easier to find jobs in construction. It takes years of experience to become a good carpenter or painter, and if you want to work as an electrician or plumber you will need not only years of experience but a license.
Other skills that are welcome on a construction site are drywalling, plastering, roofing, laying tile, brick masonry, carpet laying, installing vinyl flooring, and installing windows just to name a few.
If you have one or more of the desired skills, why not register with several construction employment agencies? They do all the work of finding you a job, and they usually have their own construction contractors board (CCB) license. They won’t send you out on a job that you don’t have the skills for; they are responsible for writing your paychecks (and making sure they don’t bounce when you try to cash or deposit them); normally they are easier to find than the actual builders might be when you need a reference for another job.
