Cost: floor levelling before installation
Area, actual required thickness and preliminary work determine the cost. Compare quotes stating accepted substrate, product, preparation and checks. A thin layer over sound material and rehabilitation of a damaged floor are different scopes.
Editorial update on 18 September 2026
Specify survey and quantities
Request area, selected thicknesses and compound quantity calculations. Separate local correction from whole-room levelling. An area rate without thickness is difficult to compare.
Identify preparation work
Separate removal, adhesive stripping, substrate repairs, proposed primer and joint protection. Define unexamined areas and pricing after exposure. An omission alone does not prove deception: request clarification.
Define handover to the next installer
Check surface assessment, covering conditions, cleaning and responsibilities when another contractor installs the finish. Obtain references and agreed results. Do not assume final flooring or structural repairs are included without a description.

Frequently asked questions
Can fibres allow a movement joint to be covered?
Not by definition. Its function and the system determine treatment, not simply the presence of fibres.
Can existing tiles be levelled over?
If assessment and product applications support it, with the required preparation. Primer alone does not establish suitability.
Is there a universal maximum thickness?
No. Check the actual product and system; the levelling category does not set one limit.
Does levelling replace screed?
Function and permitted application determine the choice, not an arbitrary boundary between millimetres and centimetres.
Can I prepare the floor myself?
First agree expected condition, checks and responsibility with the installer, and clarify old materials before intervention.
