Installing a threshold

A door threshold is a slim piece of wood fitted between rooms or different flooring areas. It provides a neat transition between floors, covers the expansion gap at doorways and helps create a clean, professional finish.

Thresholds are particularly useful where wood flooring meets another floor covering, such as carpet, vinyl or tile. They can also help prevent exposed edges and provide a smooth transition between different floor levels.

Installing a Wood Flooring Threshold

1. Prepare the Area

If replacing an existing threshold, carefully remove it using a small pry bar or flat-head screwdriver. Take care not to damage the surrounding flooring. Once removed, vacuum the area to remove any dust or debris.

2. Measure and Cut

Measure the width of the doorway and mark the measurement on the new threshold. If the threshold is joining different flooring types, choose a suitable profile for the transition. A recessed underside may be required where the threshold needs to accommodate carpet or another floor covering.

Cut the threshold to size using a suitable saw and smooth any cut edges with sandpaper.

3. Check the Fit

Position the threshold in the doorway and check that it sits correctly over the expansion gap. Open and close the door to ensure there is sufficient clearance and make any necessary adjustments.

Where the threshold meets carpet, ensure the carpet is neatly tucked beneath the profile and securely held in place.

4. Secure the Threshold

For timber or suitable subfloors, drill pilot holes through the threshold and secure it using appropriate finishing screws or nails.

Where the subfloor is concrete, adhesive may be a more suitable fixing method. Apply an appropriate flooring adhesive, position the threshold securely and place suitable weight over it while the adhesive cures. Always follow the adhesive manufacturer's recommended curing time.

Important: Thresholds should be fitted without restricting the natural movement of the wood flooring. Always maintain the manufacturer's recommended expansion gap around the perimeter and at doorways.
