There are several methods for attaching stair stringers to a deck. The best way is to bolt the stringers to the deck joists using three carriage bolts in a triangular pattern. This method offers the sturdiest fit for stairs that won’t budge. Alternatively, attach the stringers to the deck rims using lag bolts or to the posts using adjustable slope hangers.

Yes, it is possible to add an under-deck drainage system to an existing deck by retrofitting it to the structure. This process may require some prep work. For example, many drainage systems are installed on top of the deck joists, which would require you to remove the decking boards and railings first. To avoid this, you could opt for a below-the-joist drainage system. For best results and to ensure proper installation, it is recommended to consult a professional. A pro can inspect your deck, make any necessary repairs, and then install the drainage system correctly.

Most building codes require that spindles or balusters on deck and stair railings be spaced no more than four inches apart. This safety standard, often called the '4-inch sphere rule,' is designed to prevent small children or pets from slipping through the railing. A good way to visualize this is that a 4-inch sphere should not be able to pass between two spindles. For the same safety reason, the space between the bottom rail and the deck floor should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is crucial to check your local building codes to ensure compliance before starting your project.

It’s best to use two screws to secure deck boards into every joist. Securing the boards to every joist makes the deck more structurally sound, while using two screws on the outer sides of the boards can help prevent warping and cupping.
