How to Install Deck Joists & Deck Rim Plates

Are you searching for how to install deck joist on your Kansas City deck, or the correct way to install deck rim plates?

Having a custom wood or composite deck constructed on your property is a great way to extend your usable living space and increase your home’s value. However, before diving into this project, knowing how the different elements and components of deck construction work is a must.

It’s important to note that every deck builder may take a unique approach to install deck joists and rim plates; however, with proper planning, you can feel confident the work will be done properly and that the components will be stable and secure.

What Are Deck Joists?

Before any type of deck can be installed, you must have a flat, solid surface to work on. This is where the frame comes in.

Decking joists are repeated boards that serve as the structural foundation for your deck frame. These are attached to the ledge using galvanized joist hangers. In most cases, the joists will run perpendicular to your house, and the decking will run parallel to the house.

Every portion of the deck should be supported with a joist. If this isn’t the case, the deck will not be structurally sound, and it may begin to buckle or bend over time.
While joists can be made from several materials, like steel, pressure-treated lumber is most recommended.

The Deck Joist Installation Process

The deck joists being installed will be fastened to the deck or inside portion of the deck using joist hangers. These go on the interior of the rim plate and are attached using nine gauge, one and a half-inch nails. This meets code requirements for the local area.

It’s important to ensure the deck joists are level when installed. To check this, crouch down and look at the beams and ledger board at eye level. Look at the top edge and layout, one joist on the far right and one on the far left of your deck. Check to ensure the joists are as straight as possible.

The rim plates will then be attached to the house using ledge lock bolts. These are placed every 16 inches, and a spacer puck is installed behind the rim. This leaves a gap of approximately three-quarters of an inch.

In the past, rim plates were attached directly to your house’s siding. While this method works, issues can arise. With the spacer puck installed, the gap created allows air to circulate behind the boards and between the house. This helps to prevent the siding and structural components of your house behind the siding from rotting.

The Importance of Proper Deck Joist Installation

If the deck joists and deck rim plates are not installed properly, you may discover that the deck begins to lean over time. That’s because the role is to provide lateral support and keep excessive pressure from the load-bearing elements from causing problems.

Failure to ensure proper installation may cause serious problems down the road. If you work with professionals, you can feel confident installing deck joists and deck rim plates are done properly. This will also eliminate the concern of issues related to deck support down the road.
