Why is my stair carpet coming loose at the edges?
Stair carpet works loose at the nosing and the edges because that is where it is stretched hardest and walked on most. The fix depends on what is holding it.

Short answer
Find out how it is fixed: gripper rods top and bottom of each riser, a stair rod, or adhesive. Carpet lifting at the nosing has usually pulled off the gripper, and the gripper itself may have come loose from the tread. Refixing needs the carpet re-stretched onto sound gripper, not just pressed back down.
A staircase is the hardest working carpet in a house. Every foot lands within a few centimetres of the nosing, the covering is stretched around a right angle at that point, and it is pulled in two directions at once. So the edge that lifts first is nearly always the front edge of a tread, and it lifts for one of three reasons.
Safety
Step by step
- Establish how the carpet is held down.Gripper rods pinned to the tread and riser either side of the internal angle is the usual method. Stair rods, adhesive and staples all appear too, and each is refixed differently.
- Check whether the gripper itself has come loose.Press along the edge. If the whole strip moves, the pins holding the gripper to the timber have let go, and pushing the carpet back onto it achieves nothing. The gripper has to be refixed first.
- Check the tread underneath while it is exposed.Carpet lifting is a good opportunity to find a moving tread or a loose nosing. Both make the carpet work loose faster, and both are worth fixing while you can see them.
- Re-stretch rather than just pressing it back.Carpet that has lifted has usually relaxed. Simply pushing it onto the gripper leaves it slack, and it lifts again. It needs tensioning back onto the gripper with a knee kicker or a bolster.
- Renew gripper that has lost its teeth.Gripper is cheap. Old strip with bent or missing pins will not hold a stretched carpet, and reusing it is the commonest reason a repair does not last.
- Take particular care at the nosing.The carpet must be pulled tightly into the angle behind the nosing so it does not bridge. A bridged nosing wears through quickly and is exactly where a foot catches.
- Deal with worn areas rather than restretching over them.If the pile has worn through at the nosings, restretching moves the worn strip somewhere less useful. Some carpets can be lifted and moved up a step; otherwise it is a recovering job.
- Fix a temporary tack down if you cannot do it now.A loose edge on a staircase should not be left. Even a temporary fixing that removes the trip hazard is better than waiting for the proper repair.
Questions people ask
Can I just glue it down?
Adhesive on a stair carpet that was fitted on gripper rarely holds, because the carpet is under tension and the load is repeated. Refixing the gripper and re-stretching is the durable answer.
Why does it always go at the same step?
Usually because that step is where people turn, or where the tread or nosing moves. A repeated failure in one place is worth investigating underneath rather than repeatedly refixing.
