Swimming pool decks can add convenience, safety and beauty to your in-ground or above ground pool. Pool decks are available in many eye-catching textures, designs and styles - including wood, tile, concrete, marble and stone surfaces. For safety reasons, it's wise to choose a deck surface that provides some tread, as slippery decks are an injury waiting to happen if they get wet. Your deck's surface should also stay cool under the hot summer sun. Pricing of pool decks largely varies depending on the material, size, safety features and the contractor you choose. Safety extras such as pool guard rails, pool ladders and pool fencing can be added to an existing pool deck to provide extra security.
