If you're handy with tools and have some basic carpentry skills, you can probably do stone wall installations yourself. However, it's important to note that this is a fairly labor-intensive project. You'll need to excavate the area where the wall will be built, level the ground, and then lay each stone in place. The stones themselves can be quite heavy, so it's important to make sure you have someone helping you with the project. In addition, if you're not experienced in working with stone, it's best to hire a stone wall installation professional to do the job. They'll know how to properly install the stones so that your wall lasts for years to come.
