Fixing a wood threshold is a relatively simple task that can be complicated only by the surface to which it is to be fixed.

The basic fixing can be broken into simple steps.

 

Step 1 – Location

A wood threshold should be fitted so that it is bisected by the center line of the door when the door is closed. An equal amount of the threshold will show on either side of the door. Once you have the position right you should mark it on the floor.

Step 2 - Adhesive

If you are going to use adhesive you should apply this before you secure the threshold with wire nails and ensure that pressure is maintained on the threshold while the adhesive is setting to make sure there are no bubbles. 

Step 3 – Secure

If you are not going to use an adhesive it is best to secure the threshold in place with wire nails. To prevent bruising the wood threshold you should use a tack hammer for this job.

Step 4 – Drill Pilot Holes

It is best to fix your wood threshold using brass screws. These screws tend to last longer and are easier to remove because they are not affected by moisture. Put the pilot holes so that they make a pleasing pattern against the threshold.

Step 5 – Counter-Sink

Using a counter-sink bit, counter-sink the pilot holes so that the brass screws will end up flush with the upper surface of the threshold and not create a possible snagging point.

Step 6 – Screws

Drive the screws through the wood threshold using the correct screw driver and into the floor ensuring that the threshold remains in contact with the floor. If the threshold tends to rise up as you drive the screws, it may be necessary to make the pilot holes through the threshold (only) wider.

Once all the screws are securely driven home, that’s your wood threshold fixed!

In cases where the wood threshold is going to be fixed to a tile, concrete or marble floor it is necessary to use an adhesive. Although it is possible to drill into these floors and use screws it is not always acceptable because of the damage to the floor. There are several commercial adhesives available that will create a satisfactory bond and your choice will be governed by how well you think you can handle them. A contact adhesive requires precise positioning of the two surfaces to be joined while other adhesives allow some re-positioning before they set. You must also ensure that the adhesive you use is suitable for joining the two materials that you want to use it on. If your wood threshold has been stained or varnished you need to remember that you are joining the stain or the varnish – not the wood.
