From Stair Baluster Repair · Step 1 of 5 · Video by This Old House

Showing 0:08–0:36 of the source video.
Begin by inspecting the porch railing for signs of damage. The video highlights extensive rot in the lower parts of the balusters and the bottom rail, particularly where moisture has accumulated. Feel the wood for softness or 'punk' texture, indicating rot. This initial assessment helps determine which balusters need full replacement and which might be salvageable with a partial repair.
Goal: Identify all damaged sections of the porch railing
This project demonstrates how to assess and begin repairs on a rotted wooden porch railing, focusing on replacing damaged baluster bases. The process involves identifying rotten sections, removing compromised balusters, cutting new wood stock to size, and back-priming the new components to prevent future moisture damage. The repair aims to restore the structural integrity and aesthetic appeal of the porch railing.
Carefully examine the damaged baluster to identify if it is cracked, split, or completely broken. Note its attachment points to the handrail and tread. This initial assessment will guide whether a repair or full replacement is necessary.
This project outlines the steps for repairing or replacing a broken stair baluster, ensuring the safety and aesthetic integrity of your staircase.
