Girders and joists are an integral part of your deck. They work in harmony to support the entire walking area. Because these connections are so important, you need to inspect that they were both properly installed, and properly fastened.
Broken railings and stairs are a leading cause of deck related injuries. Years ago, there weren’t any codes to adhere to when constructing these elements. Most railings were simply nailed without any structural support and when people leaned on it, they failed to stay in place. Stairs are also another common area where improper installation and improper fastening is the culprit of injury.
