Why Your Subfloor May Need Professional Preparation

Professional floor leveling

A floor does not always need to be completely rebuilt to provide a suitable base for new flooring. Dips, humps, surface cracks, moisture and floor movement can all affect the finished result. Our team assesses the existing subfloor to identify these issues and determine the appropriate preparation before installation. This can include repairing surface defects, checking moisture levels and improving floor flatness where required, helping create a more stable surface for the final flooring system.

A properly prepared subfloor is also important before timber flooring installation, particularly where the finished boards need a stable and consistent base.

FLOOR LEVELLING

Our Floor Levelling Process

We inspect the subfloor, check moisture and surface defects, then prepare and prime the area before applying the suitable levelling material. After curing, we check the surface for flatness and stability, ready for laminate flooring installation or other finished flooring.

01

Subfloor Inspection

We check the existing surface for dips, high spots, movement, moisture and other conditions that could affect the finished floor.

02

Surface Preparation

Dust, loose material and minor defects are dealt with before applying the appropriate floor levelling primer or bonding system.

03

Levelling Application

The selected cement-based or flexible compound is mixed and applied at the required thickness, with careful spreading across the affected areas.

04

Final Level Check

After curing, the surface is checked for flatness, stability and readiness before the next flooring stage begins.

FLOOR LEVELLING

Flooring Types That Need a Properly Prepared Subfloor

The finished floor performs better when the base beneath it is clean, stable and suitable for the chosen flooring material. Different coverings have different preparation requirements.

01

LVT & Vinyl Flooring

LVT and vinyl flooring need a smooth, consistent base because uneven areas can become visible through the finished surface. Where required, the subfloor can be prepared before LVT and vinyl flooring installation .

02

Laminate Flooring

A stable and reasonably flat subfloor helps laminate boards sit correctly and reduces the risk of movement or visible gaps. Once preparation is complete, the floor can be ready for laminate flooring installation .

03

Hardwood Flooring

Hardwood and engineered wood flooring require a suitable, stable base to support the boards correctly. Timber subfloors may require specific preparation depending on their condition and construction.

04

Tile Flooring

Tiles need consistent support beneath them to reduce problems caused by uneven surfaces. Where required, floor preparation can be completed before tile flooring installation .

05

Carpet Flooring

Carpet also benefits from a properly prepared base, particularly where dips or surface irregularities could affect the finished appearance. A suitable subfloor provides better support for the carpet and underlay.

06

Choosing the Right Floor Preparation

The appropriate preparation depends on the subfloor type, moisture condition, surface defects, required thickness and finished flooring. Concrete, screed and timber surfaces can require different primers and levelling materials, so the existing floor should be assessed before work begins.

CONCRETE & TIMBER FLOORS

Floor Levelling for Concrete and Timber Subfloors

Concrete and timber floors behave differently, so the preparation method should match the existing surface. Concrete slabs may require correction of dips and surface variations, while timber subfloors need attention to movement, stability and the condition of the floorboards.

01

Concrete Floors

Solid concrete floors can develop dips, surface variations and uneven areas. Where required, a suitable cement-based levelling system can prepare the surface for tile flooring and other floor coverings.

02

Timber Floors

Timber subfloors can have movement between boards or changes in level across the room. The condition and stability of the floor are considered before choosing a suitable preparation method.

03

Moisture Considerations

Moisture testing may be required before levelling work begins. The results help determine whether additional preparation is needed before the chosen flooring material is installed.

Frequently Asked Questions

Floor leveling is the process of correcting an uneven or sloping subfloor before new flooring is installed, ensuring a smooth, flat surface that prevents premature wear or failure. You will need it if your floor has dips, humps, or slopes that could cause tiles to crack, laminate to buckle, or adhesive to fail over time. It is a critical preparation step for any flooring installation and is strongly recommended before laying tile, LVT, hardwood, or laminate.


The most common products used in the UK are cementitious self-levelling compounds, which are poured onto the subfloor and flow into low spots to create a flat surface. Options include rapid-setting compounds for quick turnaround, deep-fill compounds for larger depressions, and latex-modified versions for use on timber subfloors. The right product depends on your subfloor type, the degree of unevenness, and the flooring being installed on top.

Yes, floor leveling can be carried out on both concrete and timber subfloors, though the preparation and product choice differ between the two. Concrete floors typically require priming or a bonding agent before the leveling compound is applied to ensure a proper bond. Timber floors need to be firm, with any loose boards secured first, and a flexible or two-part compound should be used to accommodate natural movement in the wood.

Most standard self-levelling compounds can be applied at depths ranging from a few millimetres up to around 15mm in a single pour, while deep-fill products allow for greater depths. For larger depressions exceeding this, it is more practical and cost-effective to first fill the bulk of the void with a concrete mix or plywood, then apply the leveling compound as a finishing layer on top. Our team will assess the extent of the unevenness and recommend the most suitable approach for your floor.

Drying times vary depending on the product used, the depth of application, and the conditions in the room. Most rapid-setting compounds allow foot traffic within one to two hours and are ready for flooring installation within 24 hours. Standard compounds may require 24 to 48 hours before flooring can be laid, and the room should be kept at a stable temperature with adequate ventilation throughout the curing process.

The cost of floor leveling depends on the size of the area, the degree of unevenness, and the type of compound required for your specific subfloor. Materials such as self-levelling compounds are widely available in the UK from around £15 to £50 per bag, but professional application ensures the correct preparation, priming, and finish.
