cost of a pool fence A pool fence is the first line of defense against tragic accidents because it deters your children or pets from accessing the swimming pool without your permission or supervision. In fact, it is required by law to install a premium pool fence that has a lockable gate if you have a swimming pool at home. The average cost of installing a pool fence is $2,000 – $5,000 depending on the materials you are planning to use and the size of the fence. However, you should understand that the swimming pool gate installation price is determined by a number of factors and not solely on the number of linear feet of fence you need. Other factors that determine the installation costs of pool safety fences include: - The height of the fence - Number of gates you are buying - The surface on which the fence is being installed (grass, dirt, pavers etc.) - Layout and components that are needed during installation
