Always ask to see examples of his or her work. Putting in a metal fence is not necessarily a highly technical job, but mistakes are still common with inexperienced installers. The most common fault in metal fencing installation is that the fence is crooked. Look for symmetry in any fencing examples you are shown by the contractor.

Installing a fence requires the contractor to have certain certifications and licenses. It can sometimes be difficult to find out exactly what these certifications and licenses are. To be sure, contact your local government offices to learn more about what qualifications are required of fencing contractors in your area.

Always get an estimate before you do anything with any contractor. Most people don't realize just how expensive a fence installation can become. It is a very time-intensive process that requires a lot of material and man hours. If you get an estimate early on, you will have something to refer to if the contractor tries to raise the price later on.

Make sure the contractor is bonded. Fence installation creates a number of opportunities for damage to be done to your property and buried municipal power lines.
