How to Properly Repair a Cracked Deck

Taking the time to clean your deck is an important step for any homeowner. A thorough cleaning will reveal any underlying issues that may need repair. These problems should be repaired immediately to prevent any further damage to your deck. Before you begin the repair process, gather the tools and materials you need to complete the task. If structural damage is detected, you may want to call in an expert to help you. This can be especially true if you find signs of termites or extensive mold.

Having a professional inspect your deck can help prevent future problems. For example, it can help identify any rotten or decaying wood. Oftentimes, this rot occurs from improper construction or installation. Leaving the problem unchecked could put you or your guests at risk for injury. Termites, carpenter bees, and woodpeckers can also destroy the structure of a deck, so it is advisable to keep them under control.

Cracks in a deck are a common occurrence. Oftentimes, small cracks are not dangerous, but larger ones can lead to rot and splinters. Cracks that are less than six inches long can be filled with latex wood filler, but if they are larger, you may need to pry out the affected board and replace it.

Depending on the size and type of damage, deck repair can range from $100 to $500. Professionals will check for termites and insects, which can add up to a few hundred dollars to the overall repair cost. However, regular maintenance and staining will extend the life of your deck and keep it looking great for years.

Water damage may be the cause of rot on your deck. Water damage can also cause wood boards to bow, cup, or sag. If your deck is not treated for water damage, this problem may require more extensive repair work. It may be necessary to replace several boards, or even replace the entire joists.

If your decking joists are damaged, replacing them can cost $150 to $350 per joist. These wood beams are essential for the structural integrity of your deck. If they are damaged or are too weak, you may need to replace them. Whether you decide to replace them whole, or simply replace a section that is damaged, it’s important to secure them with deck screws.

Improperly installed joists are a common cause of warping and bowing deck boards. This can be due to improper joist spacing or inadequate support. The boards will absorb moisture from the air and become swollen, which can cause them to move fasteners in the joists. This can make the boards bow or cup, which will damage the structural integrity of the deck. For more details on deck repair and installation visit
