Who this guide is for
- Homeowners with a transition strip that lifts or catches
- People preparing to brief a flooring installer or fitter
- Anyone treating a loose threshold strip as a trip hazard
- Owners wanting a clear record before a repair visit
How the strip has loosened
Note whether the strip lifts at one end, pops up in the middle, has detached entirely, or rocks underfoot. Note whether its fixings are visible and look loose.
Describe what you see rather than deciding whether it is the fixing, adhesive, or the floor edges.
- Lifting at one end
- Popping up in the middle
- Fully detached
- Rocking or catching underfoot
Trip risk and traffic
Note where the strip is — a busy doorway, top of stairs, a hallway — and how much of a trip risk it poses. A raised strip in a traffic path deserves prompt attention.
Record whether anyone has already caught a foot on it.
The floors either side
Note the two floor types the strip joins and whether either has gapped, lifted, or moved near the strip. A lifting strip can go with floor movement at the join.
Record whether moisture, a spill, or a doormat sits at the threshold.
Photographing the strip
Photograph the lifted strip, the floors either side, and any visible fixings, and show the height of the raised edge with a coin or card. Avoid gluing or screwing it before a fitter sees what loosened it.
Note the doorway and the rooms either side.
- Show the raised edge with a coin
- Capture the floors either side and fixings
- Avoid gluing or screwing before assessment
Briefing a flooring installer
Bring your photos, the trip-risk note, and the floor types either side before contacting a flooring installer or fitter.
Let them assess what loosened it and secure it correctly; your record speeds the visit.

Common mistakes to avoid
- Gluing or screwing the strip down before a fitter sees what loosened it
- Leaving a raised strip in a busy doorway as a trip hazard
- Ignoring floor movement at the join that may have lifted the strip
- Recording the strip but not the floors either side
- Assuming a simple re-fix when the floor edges may have moved
When to involve a professional
- A flooring installer or fitter can assess what loosened a transition strip and secure it correctly
- A raised strip in a traffic path is a trip hazard, so keep it flagged and the area safe until secured
- If the floors either side have moved, mention it, as the strip may be a symptom
- What is involved varies by floor types and installation, and a professional should confirm the cause
Frequently asked questions
Questions readers ask about this topic
Is a lifting transition strip dangerous?
A raised strip at a doorway or stair top is a trip hazard, especially in traffic paths. Flag where it is and how high it stands, keep the area safe, and have a fitter secure it rather than leaving it.
Can I just glue it back down?
Gluing or screwing it before a fitter sees what loosened it can mask a floor-movement issue at the join. It is more useful to document the strip and the floors either side and let a professional secure it.
Why does the strip keep lifting?
Recurrent lifting can point to the floors either side moving at the join, not just the strip's fixing. Noting any gapping or movement near the strip helps a fitter judge whether the floor edges are involved.
What should I show the fitter?
Photos of the lifted strip with the raised edge shown by a coin, the floors either side, and any visible fixings, plus a note on the trip risk. That helps a fitter come prepared to secure it properly.
