Deck hangers are commonly used in construction to provide additional support to wooden deck structures. These metal brackets are designed to attach the deck frame securely to the house, offering stability and preventing movements that could cause damage. However, there is a concern amongst homeowners and builders about whether deck hangers can cause harm to the wood. In this article, we will delve into this topic and shed light on the potential risks and ways to mitigate them.
Understanding Deck Hangers
Deck hangers, also known as deck joist hangers or deck brackets, are typically made of galvanized steel. Their purpose is to connect the joists of a deck to the ledger board on the house, ensuring a secure and sturdy attachment. These brackets come in various shapes and sizes to accommodate different deck configurations, and they are installed with nails or screws to provide maximum holding power.
The Risk of Wood Damage
One of the main concerns regarding deck hangers is the potential for wood damage. The primary way deck hangers can harm the wood is through puncturing, splitting, or compressing the wood fibers during installation. This is especially true if the hangers are not properly aligned or if excessive force is applied during the attachment process.
Puncturing the Wood
Improper installation of deck hangers may lead to the puncturing of wood, which can weaken the structural integrity of the deck over time. When the bracket is nailed or screwed into the wood, the fasteners can create holes that compromise the strength of the joist or ledger board.
Splitting the Wood
Another risk of using deck hangers is the potential for splitting the wood. If the nails or screws are not installed at the correct angle or if excessive force is applied, it can cause the wood to split along the grain. This splitting weakens the wood and can lead to further damage or even structural failure.
Compressing the Wood Fibers
Deck hangers that are over-tightened can compress and crush the wood fibers. This compression can reduce the structural capacity of the wood, making it more susceptible to bending, warping, or snapping under load. It is important to ensure the deck hangers are attached securely without causing excessive compression.
Mitigating the Risks
Fortunately, there are several ways to mitigate the risks associated with deck hangers and prevent potential wood damage.
Proper Alignment and Installation
The first step to minimizing the chances of wood damage is ensuring proper alignment and installation of the deck hangers. It is crucial to follow the manufacturer’s guidelines and use the recommended nails or screws. Take care to align the brackets correctly and use a level to ensure they are straight before attaching them to the wood. Additionally, always avoid using excessive force when installing the deck hangers to prevent puncturing or splitting of the wood.
Pre-drilling Holes
Pre-drilling pilot holes for the nails or screws can significantly reduce the risk of splitting the wood. By creating a small pathway before inserting the fasteners, the wood fibers are less likely to split when the hangers are attached. This simple step can help maintain the integrity of the wood and prevent structural issues.
Regular Maintenance
Regular maintenance is essential for preserving the integrity of the wood and prolonging the lifespan of the deck. Inspect the deck hangers periodically and replace any damaged or worn-out brackets. Keeping the deck clean and free from debris can also prevent moisture buildup, which can cause wood rot or decay over time.
While there is a potential risk of deck hangers damaging wood if not installed properly, these risks can be mitigated with the right techniques and regular maintenance. By taking the necessary precautions, such as proper alignment, pre-drilling pilot holes, and regular inspections, homeowners and builders can maximize the support provided by deck hangers while minimizing the likelihood of wood damage. It is crucial to prioritize safety and ensure the longevity of your deck structure.
