Deck hangers, also known as joist hangers, play a crucial role in ensuring the stability and longevity of a deck. They are metal brackets that connect the deck joists to the ledger board or the beam, providing additional support and preventing the joists from pulling away from the main structure. In the ideal scenario, deck hangers should be installed during the deck construction process. However, if you have overlooked this step or are considering adding deck hangers to an existing deck, you may be wondering if it is possible to install them post deck construction. Let’s explore this topic in more detail.
Assessing the Feasibility
Before diving into the process of installing deck hangers post deck construction, it is important to assess the feasibility of the task. While it is technically possible to install deck hangers after the deck has already been built, there are several factors to consider.
- Accessibility: One of the main challenges of installing deck hangers post deck construction is the limited accessibility. The deck surface and the underneath framework may be obstructed by decking boards, posts, or railings, making it difficult to attach the hangers securely.
- Structural Integrity: Adding deck hangers after the deck has been built may compromise the structural integrity of the deck. The existing connections and load-bearing capacity should be thoroughly evaluated before proceeding with the installation.
- Code Compliance: Depending on your location, there may be building codes and regulations that dictate the specific requirements for deck construction. Adding deck hangers after the fact may not meet these regulations, so it is essential to consult with a local building inspector or a structural engineer.
Determining the Best Approach
If you have determined that it is feasible and necessary to install deck hangers post deck construction, there are a few different approaches you can consider. The most appropriate method will depend on the deck’s design, materials, and accessibility.
- Partial Deck Disassembly: In some cases, it may be necessary to partially disassemble the deck to gain access to the necessary areas for installing deck hangers. This approach is more viable for decks with fewer obstructions, such as simple deck designs without complex features like stairs or multiple levels.
- Surface-mounted Hangers: Another option is to use surface-mounted deck hangers that can be attached to the sides of the deck joists. These hangers do not require any structural modifications and can be installed without disassembling or compromising the existing deck structure. Surface-mounted hangers are typically made of metal and are designed to be resistant to corrosion and other environmental factors.
- Seek Professional Help: If the installation becomes complex or compromises the overall integrity of the deck, it is advisable to seek professional help. A structural engineer or a licensed contractor will be able to evaluate the existing deck and provide recommendations for the best course of action. They can assess the load-bearing capacity, review building codes, and ensure that the installation is done correctly.
While it is technically possible to install deck hangers post deck construction, it is important to approach this task with caution. Before proceeding, assess the feasibility, accessibility, structural integrity, and compliance with building codes. Depending on the circumstances, you may need to partially disassemble the deck or opt for surface-mounted hangers. Seeking professional advice is recommended to ensure the installation is done correctly and to guarantee the safety and longevity of the deck.
