How to replace a stair handrail

Before you can fit a new stair railing, you’ll need to remove the old one. If you’re planning to reuse the spindles, take extra care when detaching them. Start by unscrewing the handrail brackets and gently lifting the railing away from the wall. Remove each spindle, again ensuring they don’t get damaged if you plan to reinstall them.

Once the old bannister is removed, check the staircase for any signs of wear. Sand down any rough patches, fill in unwanted holes and smooth out any imperfections. If you’re using existing fixing points, ensure they’re in good condition and ready for your new stair handrail.

Precision is key when fitting a stair railing. Double-check your measurements before cutting – it's better to trim excess wood gradually than to cut too short. Place the railing in position to test the fit, making adjustments as needed. Once you’re happy, sand and finish the wood to match your staircase.

Spindles support your stair handrail and add a decorative element, so spacing them correctly is important. The standard gap between each spindle is about four inches, ensuring safety while keeping the design balanced. Mark the positions on both the handrail and base rail before securing them in place.

Now it's time to bring everything together. Start by attaching the spindles, making sure they’re evenly spaced and securely fixed. Then, carefully position the new handrail, checking for a snug fit before securing it with countersunk screws. Fix the railing to the wall, cover any visible screw holes and sand any rough edges for a smooth finish. Once everything is in place, you can add a coat of paint or stain to match your décor.
