TIPS FOR FIXING A WOBBLY DECK RAILING: DIY


If you have a patio, balcony, or deck that is elevated from the ground, it is crucial to ensure that the railing is secure. Over time, old railings can become unsteady at the joints, which can pose a safety hazard. But, with some basic knowledge and effort, you can fix the railing and enjoy your outdoor space with peace of mind.

Reasons for Loose Deck Railings A variety of factors can contribute to a wobbly deck railing, such as windy weather, people leaning too hard on them, and age. For example, wood railings can become loose because they expand and contract with exposure to moisture or heat, causing the bolts and screws to loosen over time. Metal railings can become unsteady because they may rust or become worn, especially when exposed to rain and humidity. Weather can also be a major factor in causing railings to come loose, such as strong winds or hail that can damage the joints and fasteners.

Fixing a Wobbly Wood Railing Wood railings provide a natural outdoor look and are often a more budget-friendly option. However, they are less durable than metal and plastic railings and often require repairs and maintenance to extend their lifespan. With some experience, fixing a wobbly wooden railing can be done easily and affordably. The steps to fixing a wobbly wooden railing include tightening any loose carriage bolts or screws and adding pressure-treated blocking between rim joists.


  1. Clean rust: Start by removing any rust from the railing, especially at the connectors and screws, using white vinegar and a clean rag.

  2. Tighten hardware: Check the anchoring screws or bolts at each deck railing post and tighten them with a power drill or ratchet if they're loose.

  3. Replace connectors: Replace any broken or worn post connectors to prevent added stress on the other anchors. Use appropriate screws for the type of deck.

  4. Inspect brackets: Check for any damage to the post-to-rail brackets that could cause a loose railing section and repair or replace as necessary.

  5. Add post covers: Protect post hardware by adding post skirts or post base covers to the bottom of the posts, to prevent future damage from exposure to the elements.
