Gazebos: How to Install a Gazebo Railing and Trim

Gazebo Railings

Any standard wood deck railing system or custom deck railing can be used for gazebo construction. Any gazebo that is set more than 12” above grade will require a rail to meet building code. Check local codes to determine specifics. In general, rails are 36” to 42” in height, and have spindles or “balusters” spaced less than 4” apart.

There are also rules regarding width and thickness of rail cap, check local codes to determine specifics. In general, most rail systems are designed to meet code.

1. Measure between posts at the height of the top of your rail and at the height of the bottom of your rail to ensure proper fit.
2. Cut top and bottom rails to fit each section specifically. A miter saw works best.
3. Install your bottom rail between posts first. If you are using a sectional rail system, the whole rail may be installed at once. Use spacer blocks under the bottom rail to hold it at the proper height. Use a level to double check the pitch of the rail.
4. Install rail with fasteners to both posts. If brackets are used, attach brackets first, then position bottom rail to fit. Otherwise, pre-drill your rails to prevent splitting and use screws to fasten them in place.
5. Fit your balusters or spindles into the bottom rail and fit the top rail in position on top of the spindles.
6. Fasten the top rail in position as you did the bottom.

Gazebo Trim

Trim pieces such as corner brackets, or corbels are often fitted into the 90° corners between the horizontal roof framing and the posts, or the top rail and posts.

Brackets are often cut out, fitted with decorative beads and appliques, or made from metal. Corbels are solid wood or plaster brackets. Both are typically triangle shaped.

1. Fit the brackets into the corner and mark any and all screw holes on the bracket to the rail, post, or horizontal frame.
2. Drill pilot holes through the brackets if they do not exist already. Mark the holes as described in step one.
3. Fasten the bracket in place with the screws provided with your bracket or corbel, or deck screws.

Wooden trim pieces can be used to cover gaps in construction around post bases and other places. When using screws to fasten trim, always predrill before installation.
