Subfloor Preparation & Floor Levelling in Cheltenham
What is subfloor preparation?
Subfloor preparation is the process of bringing an existing floor into the appropriate condition to receive its intended finish.
Every floor is different. A concrete slab with old adhesive residue presents a very different set of challenges to a newly laid screed, an anhydrite floor or a previously painted garage floor.
Depending on the substrate and intended finish, preparation can include:
- Removing old adhesive, paint, laitance or other contaminants
- Mechanical floor grinding
- Repairing cracks and damaged concrete or screed
- Stabilising weak or friable areas
- Moisture testing and assessment
- Installing a suitable damp proof membrane
- Priming
- Correcting high and low areas
- Applying levelling or smoothing compounds
- Checking surface regularity before the final floor covering is installed
The right preparation system is determined by the existing substrate, its condition, moisture levels, required build-up and the flooring system going over it.
Manufacturer-trained in floor preparation systems
I’ve undertaken relevant floor preparation training with leading manufacturers ARDEX, F. Ball and Mapei, building practical knowledge around the products and systems used to prepare floors for professional finishes.
This training complements my hands-on experience, helping me approach each floor according to its substrate, condition, moisture requirements and intended finish, rather than applying a one-size-fits-all solution.

Moisture testing
I carry out floor moisture testing where moisture could affect the installation or performance of a new floor covering. Moisture levels, substrate type and the intended flooring system all need to be considered when deciding whether further drying, treatment or a compatible DPM system is required.
Latex floor levelling
I provide latex floor levelling using suitable latex-modified levelling and smoothing systems where appropriate for the substrate and intended finish. These systems can be particularly useful when preparing floors for resilient coverings, but the correct product and application method depend on the existing floor, required thickness and manufacturer’s specifications.
Subfloor stabilisation
Where a substrate is weak, friable or otherwise unsuitable, I can carry out subfloor stabilisation to improve its condition before further preparation. The appropriate approach depends on why the substrate is unstable and what flooring system is being installed above it, rather than simply covering the problem with a new layer.

Damp floor repair
A damp floor can cause problems for adhesives, levelling compounds and moisture-sensitive floor coverings. I investigate the condition of the existing substrate and can incorporate appropriate moisture management, DPM installation and floor preparation into the wider repair system, helping create a suitable base for the finished floor.
Uneven floor repair
I provide uneven floor repair in Cheltenham for floors affected by high spots, depressions, inconsistent levels or general surface irregularities. Depending on the condition and required finished level, I may use mechanical grinding, localised repairs, smoothing or levelling compounds to create a more suitable substrate for the final floor covering.
Floor levelling
I provide professional floor levelling in Cheltenham to correct differences in floor height and create a more consistent substrate for the finished floor. I assess the existing floor, required build-up and intended finish before selecting an appropriate levelling system, whether preparing for LVT, tiles, resin, microcement or another floor covering.
Floor smoothing
I use floor smoothing compounds to create a smooth, consistent surface where the existing substrate has minor imperfections, texture or irregularities. Careful preparation and product selection are important, particularly beneath thin floor coverings such as LVT, where imperfections in the substrate can become noticeable through the finished flooring.
