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.

Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could build a floating deck in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.

The proper and most comfortable height for a deck stair riser, also called a step, is between four and seven inches. A height of seven inches is often considered ideal for a strain-free step that minimizes the risk of trips and falls. While it is possible to have risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. For optimal safety and comfort, pair a seven-inch riser with a tread depth (or run) of at least 10 to 12 inches. Always check your local building codes, as they may have specific requirements that differ from these general recommendations.

When building an outdoor or deck gate, it's crucial to use durable wood that can withstand harsh weather conditions like sunlight, rain, wind, and snow. Redwood and cedar are excellent choices as they naturally resist decay. While redwood is considered more elegant, cedar is a more affordable option. Other suitable woods include oak and pressure-treated pine, which is specifically treated to resist rot. Although some softwoods like pine are popular, untreated softwoods such as pine and spruce should generally be avoided for outdoor projects because they are susceptible to damage from water, rot, and the sun. Ultimately, it's wise to consider your local climate when selecting the right wood for your gate.
