How to Tighten a Loose Banister

Grand staircases become decidedly less grand if the banister is loose, wobbling every time it's used. Not only is this unattractive, it can become a safety hazard as the banister becomes looser. Tightening the connection between the banister's balusters and the handrail or the stair's tread is a simple task, but take care to ensure that the repair is invisible.

Drill
1/16-inch bit
4d finishing nails
Hammer
Nail set
Wood putty
Putty knife
Paper towel
Wood touch-up marker or paint

Instructions

- 1
  Drill two 1/16-inch pilot holes into opposite sides of the baluster's loose end, passing diagonally through the baluster and into the handrail or stair tread.
- 2
  Drive two 4d finishing nails through the pilot holes, securing the end of the baluster tightly to the handrail or stair tread.
- 3
  Countersink the nails slightly below the baluster's surface using a nail set.
- 4
  Fill the countersunk nail holes with wood putty. Scrape the putty smooth with a putty knife and wipe off any excess around the hole with a wet paper towel.
- 5
  Allow the putty to dry for the amount of time recommended on the container.
- 6
  Color the putty-filled nail holes with a wood touch-up marker that matches the baluster. If the baluster is painted, use identical paint to cover the putty.
- 7
  Repeat this process for all other loose balusters. If any are loose on the top and bottom, tighten both following the same steps.
