Today, we continue with part three of our pool improvement series: pool liners. Swimming pool liners can make a dramatic difference in the look of your swimming pool. If you have had your pool for an extended period of time, your liner may be weak and brittle. Constant exposure to sun light and chemicals can cause the liner to thin and eventually break. This can not only cause ugly discoloration, but also pool leaks or collapse. If you notice excessive fading or cracking of your liner, it needs to be replaced. With the variety of beautiful pool liner options available, this can also provide a totally new look for your pool. Pictured above (left to right), Monteray, Rolling Rock, Sunlight, and Dolphina are only a few of the many eye-catching liners available to improve your swimming pool.
