Install Balusters and Handrail

What happens in this clip

Begin by inserting each baluster into its corresponding pre-drilled hole in the stair tread. Apply construction adhesive into the tread holes before inserting the balusters for a stronger bond. Tap each baluster gently with a mallet to ensure it is fully seated and plumb. Once all balusters are set into the treads, carefully lift the assembled handrail (which includes the turnout section). With an assistant's help, meticulously align the pre-drilled holes on the underside of the handrail with the top tenons of each baluster. Slowly lower the handrail, guiding each baluster into its respective hole. Once all balusters are seated in the handrail, gently tap the handrail with a rubber mallet or a hammer protected by a wood block to ensure a tight, secure fit. Finally, secure the handrail to the newel post at the top of the stairs, and to the wall, completing the installation. (The video implies securing but doesn't explicitly show the final fasteners for the top connection.)

Goal: With all holes drilled and prepared, insert the balusters into the stair treads and then carefully place the assembled handrail over the balusters, tapping it into place for a secure fit.

About the full video

This video provides a detailed guide on installing a wooden stair railing, focusing on precise techniques using pre-drilled holes for balusters and secure joinery for handrail sections. The process includes preparing stair treads, assembling the handrail, marking and drilling accurate baluster holes, and final assembly to create a stable and aesthetically pleasing railing.

Step 4 of 6: Install New Balusters and Handrails

Begin by marking the spacing for your balusters according to local building codes (typically no more than 4 inches apart). Attach the balusters to the treads (or shoe or skirt board) and to the underside of the handrail. Use appropriate fasteners, such as baluster mounting kits or screws, ensuring they are strong and concealed if possible. Next, attach the handrail to the newel posts and to any supporting brackets. Ensure the handrail is at the correct height (typically 34-38 inches from the tread nosing) and is securely mounted to provide adequate support.
