What happens in this clip
After the baluster has been accurately trimmed to size (the cutting process is not shown in this segment), apply a generous amount of wood glue, specifically Titebond Premium Wood Glue, around the removable locator pin at the bottom of the baluster. Carefully insert the glued pin into the prepared, recessed hole on the stair tread. To attach the top of the baluster, gently lift the handrail upwards just enough to create space. Then, guide the tapered top end of the baluster into its corresponding hole in the handrail. Once both the bottom pin and the top are seated, twist the baluster slightly to ensure the glue spreads evenly. Immediately wipe away any excess glue that oozes out with a damp rag for a clean finish. The goal is for the baluster to fit snugly and securely without the need for additional caulk.

About the full video
This project details the process of replacing balusters on a staircase without removing the handrail. It involves preparing the existing holes on the stair treads, accurately measuring and trimming new tapered balusters with removable locator pins, and then gluing them into place. The project emphasizes precise fitting to achieve a clean, professional finish.
Step 4 of 5: Install New Baluster
Apply wood glue to the tenons or ends of the new baluster that will connect to the handrail and tread. Position the baluster in place. If it uses dowels, insert them into the corresponding holes. If it screws in, pre-drill pilot holes and drive screws. For mortised connections, ensure a snug fit and secure with glue. Ensure the baluster is plumb and securely fastened.

Questions about Stair Baluster Repair
Do I really need a miter saw for this project, or are there alternatives if I don't own one?
While a miter saw provides precise cuts for the baluster, you might be able to get a new baluster pre-cut to size at a hardware store. Alternatively, a handsaw with a miter box could work for smaller adjustments, but ensure clean, accurate cuts for a secure fit. Always wear appropriate safety gear when cutting.
What are the most important safety precautions I should take when repairing a stair baluster?
The primary safety concern is ensuring the staircase remains stable during and after the repair. Always wear eye protection when using tools like pry bars or saws to avoid injury from flying debris. Be mindful of splinters when handling wood and ensure the new baluster is securely fastened to prevent future accidents.
What is a common mistake beginners make when installing a new baluster, and how can I avoid it?
A frequent error is incorrect measurement, leading to a loose or too-tight fit. Measure multiple times, ensuring the new baluster fits snugly but without forcing it, which could damage the handrail or tread. Also, make sure to use adequate construction adhesive and fasteners to properly secure the baluster for long-term safety and stability.
The project is listed as "beginner" and "3 hours." What if it takes longer, or I encounter unexpected issues?
The 3-hour estimate is for straightforward replacements. It might take longer if you encounter hidden damage, struggle with removing the old baluster, or need to make precise cuts. Take your time with each step, especially measurements and securing the new baluster, to ensure a safe and lasting repair. If the structural integrity of the staircase seems compromised, consider consulting a professional.
How can I ensure the new baluster matches the existing ones, especially in terms of style and finish?
To ensure a good match, select a new baluster that has the same dimensions and style as your existing ones, such as the 5015 tapered wood baluster specified. If your existing balusters are painted or stained, you'll need to prime and finish the new baluster to blend seamlessly. Bring a piece of the old baluster to the store for comparison if possible.
After installation, what steps can I take to ensure the new baluster is well-reinforced and won't break again soon?
Beyond just friction-fitting, use construction adhesive and appropriate screws or nails to secure both ends of the baluster firmly to the handrail and tread. Regularly check the stability of all balusters on your staircase, as a single broken one can indicate overall wear. Proper finishing also protects the wood from environmental damage and prolongs its lifespan.
