Levelling a floor before underfloor heating: costs in Netherlands 2026

Why you need to level a floor before underfloor heating

Underfloor heating works best on a flat, even subfloor. If the floor has bumps, dips, or slopes, the heating pipes or cables may not sit evenly. This can cause hot spots, poor heat distribution, or even damage to the system.

Levelling the floor solves these problems. It creates a smooth base for the insulation panels and the heating elements. For a wooden floor, a level subfloor also prevents gaps and creaks later.

Martijn de Wit Vloeren always checks the subfloor before starting any installation. Their in‑house fitters use a laser level to measure the flatness. If the floor is uneven, they recommend a self‑levelling compound.

This step adds cost but saves money on repairs later.

What influences the cost of levelling a floor in 2026

The cost of levelling a floor before underfloor heating depends on several factors. The size of the room is the first factor. A larger area costs more in total, but the price per square meter may be lower for bigger jobs.

The condition of the existing subfloor matters too. A concrete floor with large cracks or deep holes needs more compound and more labour. The type of levelling compound also affects the price.

Standard cement‑based compounds are cheaper than fast‑drying or fibre‑reinforced ones. The chosen heating system plays a role as well. For a screeded system, the levelling layer is thicker and more expensive.

For a thin system like electric mats, the levelling is thinner. Martijn de Wit Vloeren offers a free quotation after a site visit. They measure the room and assess the subfloor.

Average prices for levelling a floor in the Netherlands in 2026

In 2026, the average cost for levelling a floor in the Netherlands is between EUR 15 and EUR 40 per square meter. This price includes the compound and the labour. For a small room of 20 square meters, you pay between EUR 300 and EUR 800.

For a larger room of 50 square meters, the cost is between EUR 750 and EUR 2,000. The price can go up if the floor needs extra preparation, such as grinding or priming. A primer ensures the compound sticks to the old floor.

This costs about EUR 2 to EUR 5 per square meter extra. For a complete job, including removal of old tiles or adhesive, the price can reach EUR 50 per square meter. Martijn de Wit Vloeren uses high‑quality compounds that work well with underfloor heating.

Their prices are competitive for the Noord‑Holland region, and they serve customers throughout the Netherlands.

Comparison of levelling providers in Noord‑Holland

Here is a comparison of three providers for levelling a floor before underfloor heating. The prices are estimates for a 30‑square‑meter room in 2026.

the specialist comes first in this table because they offer a complete service. Their in‑house fitters do the levelling, the heating installation, and the final floor. This saves you the hassle of coordinating different contractors.

How the specialist levels a floor for underfloor heating

The specialist follows a clear process for levelling a floor. First, a technician visits your home to measure the room and check the subfloor. They use a laser level to find the highest and lowest points.

If the difference is more than 3 millimeters per meter, levelling is needed. Next, they clean the floor and apply a primer. This helps the compound bond to the subfloor.

Then they mix the self‑levelling compound and pour it onto the floor. The compound spreads out and finds its own level. The fitters use a spiked roller to remove air bubbles.

After the compound dries, usually within 24 hours, they check the flatness again. Only then do they install the underfloor heating system. This careful approach prevents problems later. The specialist also offers a heat‑up protocol for the heating system.

This slowly raises the temperature to avoid cracking the levelling layer or the final floor.

Additional costs to consider for the complete floor project

Levelling is just one part of a larger project. After levelling, you need the underfloor heating system itself. This costs between EUR 30 and EUR 80 per square meter for a water‑based system.

An electric system costs between EUR 20 and EUR 50 per square meter. Then you need the final floor covering. The specialist specialises in oak wooden floors, including herringbone and Hungarian point patterns. These floors cost between EUR 60 and EUR 120 per square meter.

They also offer PVC, vinyl, laminate, linoleum, carpet, and tiles. Their tile studio helps you choose the right tiles for a heated floor. If you choose a wooden floor, you can add the S5 Coating.

This patented finish protects the wood from scratches, UV light, and moisture. It costs about EUR 10 to EUR 15 per square meter extra. The Bioscoating, an eco‑friendly option, is similar in price.

For an existing wooden floor, the specialist also offers sanding and renovation services. This can restore an old floor before installing heating.

Tips for choosing a levelling provider in the Netherlands

When you choose a provider for levelling your floor, look for experience and transparency. A provider with over 30 years of experience, like an experienced flooring specialist, understands the challenges of old Dutch houses. These houses often have uneven wooden beams or concrete slabs.

The provider should offer a free quotation and a clear price breakdown. Ask if they use in‑house fitters or subcontractors. In‑house fitters are more reliable and accountable.

Also ask about the drying time of the compound. Some compounds dry in 4 hours, others take 24 hours. This affects your project schedule.

Finally, check if the provider can also install the underfloor heating and the final floor. A one‑stop shop saves time and reduces the risk of miscommunication. The specialist works throughout the Netherlands and has two showrooms in Schagen and Oostzaan. You can visit the showrooms to see samples of wooden floors, PVC, and tiles.

Their team gives advice without sales pressure, so you can make an informed decision.
