Floor and concrete boundaries
Uneven room thresholds: what should demolition remove?
Should a raised threshold come out with the floor or remain for the next installer?
A difference in floor height may come from finish layers, backing, a threshold or underlying construction. Do not instruct removal down to a neighbouring level without knowing what creates the difference. Give the installer the desired transition and let the assessment establish the removable layers.
Planning guidance by MetroPoint Demolition. Site conditions and the agreed professional scope determine the final removal.
Compare the boundaries
Loose transition piece
Identify it separately from the flooring on each side.
Built-up floor edge
Document the layers visible at an existing exposed edge without disturbing them.
Underlying level difference
Levelling or structural changes are separate from finish removal and need their own review.
Record levels as observations, not demolition depths
A photograph with a simple reference dimension can show the visible height difference. It does not establish slab thickness, joist position or concealed material. Mark which side remains and whether the adjoining door will also change. The new floor build-up may resolve the transition differently from the old one.
Ask the receiving installer what condition they need at the doorway before choosing how much to remove. If the answer depends on the concealed assembly, use a review point after authorised exposure. A clean-looking edge is not evidence that the new transition will be flush.
Questions for the assessment
- Which adjoining floor remains?
- What new build-up is proposed?
- Who decides whether the threshold or backing is removed?
Choose the next step
Read the matching service scope and exclusions, then describe what you want removed and what must remain. Your service choice can be corrected in the form.
