Repairing a Carpet Threshold
You will find that the carpet threshold abutting the door will sometimes be the location where the most wear and tear will occur. Knowing how to repair this section of carpet will ensure that the flooring looks its best (Fig. 1 and 2). But first, examine the transition carefully to make sure the right type is used for that threshold.
Step 1 - Remove Damaged Section
If the carpet threshold has been damaged beyond what cleaning can repair, it will be necessary to remove this section to replace it. Lay a straightedge at the edge of the damaged section, hold it firmly to enable you to run the blade of a utility knife along the edge. Take care not to cut the underlay, which can remain in place if it hasn’t suffered damage (Fig. 3).
Step 2 - Cut Carpet
After vacuuming away any loose carpet fibers that have resulted from the work, carefully measure the recess. To ensure that the carpet threshold looks good, make sure that the replacement carpet is an exact match. Check the grain of the pile to ensure it is the right way around and measure carefully.
Step 3 - Attach Replacement
Fix the carpet in place and secure the carpet transition in place by using a hammer to insert tacks around the edges.
