From Stair Baluster Repair · Step 3 of 5 · Video by The Honest Carpenter

Showing 2:14–3:03 of the source video.
The new baluster needs to be the same length as the existing ones. In this case, the store-bought balusters are already 42 inches, matching the existing ones, so no cutting is required. If your new balusters are too long, measure an existing baluster from top to bottom. Use a miter saw or a circular saw to cut the new baluster to the correct length, ensuring to preserve any miter cut on the bottom end and make a square cut at the top. The new balusters in the video have a mitered detail on the bottom end and a square cut on the top.
Goal: Cut new balusters to match the length of existing ones
This project provides step-by-step instructions on how to replace damaged deck balusters. It covers the process from removing old, nailed-on balusters to installing new ones securely with screws, emphasizing proper sizing, pre-drilling, countersinking, and spacing techniques for a durable and aesthetically pleasing result.
Measure the length of the old baluster or the gap it occupied. Cut the new baluster to the exact size using a miter saw or handsaw. If the baluster has decorative elements or specific end profiles (e.g., tenons), replicate these on the new one using appropriate woodworking tools. Sand any rough edges smooth.
This project outlines the steps for repairing or replacing a broken stair baluster, ensuring the safety and aesthetic integrity of your staircase.
