Before ever taking on your own DIY fence installation, the most important thing you need to do is know where your property begins and ends. Randomly deciding to install a fence without knowing how to find your property line can lead to arguments with your neighbor, expensive repairs when you have to tear down and re-install the fence and potential legal fees should your local county gets involved in the issue. In other words, ignorance is not bliss when it comes to not knowing your property lines!
