1. Determine your purpose. Are you looking for aesthetic appeal only? Do you want to keep your children in, dogs out, etc.? Do you want a noise reducer, or privacy barrier? Do you want to keep a pet in? You have to know why you want a fence so you can pick the fence that is right for you.
2. What is your yard like? Some fencing simply does not work well with various landscapes. For example, if you live in a hilly area, and your yard is full of slopes, you may have an unsightly fence when you put it up, or a installation nightmare. Knowing your yard helps you choose a fence that makes fencing easier, and the end result better looking. For example, on a yard that has many ups and downs, you may want to consider a stair stepped fencing system.
3. How much maintenance can you commit to the fence? Fences look great when they are new, but a charming wood fence turns into a headache when it is weathered, warped, and the paint is peeling. Vinyl is maintenance free for the most part, minus the need for an occasional washing. However, there are various types of vinyl to choose from. Treated wood, metal, wire, etc. are all less expensive options.
4. Know your budget. How much you have to spend will limit your options, so setting a realistic budget, and evaluating if you can meet your needs with it is important.
5. What are your building codes, restrictions? When choosing fencing you want to consider any city or municipal building codes, such as how far from a home, etc. You may need a permit to fence, so make sure you check into it. In addition, check with any association your home belongs to. If your HOA has guidelines for it, your time and money may be wasted if you put in a fence that goes against their regulations. Check first so you do not pay later.
6. What about your neighbors? Will putting a fence up cause a problem with the neighbors? In some cases a fence will benefit both parties, and thus they may even be willing to go in on it 50/50 with you. In others it may block their view, or cause a problem. So, before installing something so costly, time consuming, and property changing, talk to your neighbor.
7. What kind of warranty is offered? Fencing comes with limited warranties that generally protect against structural failure. However, this means that you get nothing from the warranty unless your fence collapses on its own. So, look for installation warranties as well, to ensure that if the contractor does a crappy job, you do not have to pay for it.
