Levelling an uneven subfloor before laying parquet in the Netherlands 2026

Why levelling an uneven subfloor is crucial for parquet in the Netherlands 2026

An uneven subfloor is one of the most common problems when installing parquet in Dutch homes. Many houses in the Noord-Holland region have older concrete or wooden subfloors that have settled over time. If you lay parquet on an uneven surface, the floor can develop squeaks, gaps, or even broken joints.

This is especially true for herringbone and Hungarian point patterns, which require a perfectly flat base. In 2026, the Dutch building standards still require a maximum deviation of 2 mm per meter for parquet. Martijn de Wit Vloeren, with over 30 years of experience, always checks the subfloor first and advises on the best levelling method.

Self-levelling compound: the most common solution for concrete subfloors

For concrete subfloors in Dutch homes, a self-levelling compound is the standard solution. This is a liquid mixture that you pour over the concrete. It spreads out and creates a flat, smooth surface.

The compound dries within 24 to 48 hours, depending on the thickness and humidity. Prices for a self-levelling compound in the Netherlands range from EUR 10 to EUR 25 per m2, including labour. Martijn de Wit Vloeren uses high-quality compounds that work well with underfloor heating.

They apply the compound in layers up to 10 mm thick. If the subfloor has larger dips, they first use a repair mortar to fill deep holes.

Plywood or OSB boards for wooden subfloors in Dutch homes

Many older homes in the Netherlands, especially in Schagen and Oostzaan, have wooden subfloors. These can be uneven due to warped beams or old floorboards. For wooden subfloors, a layer of plywood or OSB boards is often the best choice.

The boards are screwed down and create a stable, flat base for the parquet. This method is also suitable for herringbone patterns. The cost for plywood boards is around EUR 15 to EUR 30 per m2, plus installation.

Martijn de Wit Vloeren has in-house fitters who can install these boards precisely. They also recommend a moisture barrier between the wood and the parquet to prevent swelling.

Grinding down high spots: a quick fix for small unevenness

If your subfloor has a few high spots but is otherwise flat, grinding can be a fast solution. A concrete grinder removes bumps and ridges of up to 5 mm. This method is cheaper than a full self-levelling compound, with prices around EUR 5 to EUR 10 per m2.

However, grinding is not suitable for large areas or deep dips. the specialist can assess whether grinding is enough or if you need a compound. Their team uses professional grinders with dust extraction to keep your home clean. This is a practical option for many homes in the Netherlands where the subfloor is mostly flat but has a few uneven spots.

Underfloor heating and levelling: the 2026 heat-up protocol

If you have underfloor heating, levelling the subfloor is even more important. An uneven layer of compound can cause the heating to work unevenly, leading to hot and cold spots. In the Netherlands, a specific heat-up protocol is required for new floors over underfloor heating.

This involves gradually increasing the temperature over 7 to 14 days. the specialist advises on this protocol and can install the heating system as well. They use a primer before applying the self-levelling compound to ensure good adhesion. The total cost for levelling with underfloor heating preparation is around EUR 20 to EUR 40 per m2.

This includes the compound, primer, and labour by their in-house tilers.

How to choose the right levelling method for your Dutch home in 2026

Start by checking your subfloor type. Concrete subfloors in newer Dutch homes are often flat but may need a thin layer of compound. Older homes with wooden floors may need plywood or OSB boards.

If you have underfloor heating, always use a compound that is certified for heating systems. the specialist offers free quotations and a personal visit to your home in the Noord-Holland region. They measure the floor with a laser level and recommend the best solution. Their team of in-house fitters and tilers then completes the work without subcontractors.

This guarantees a consistent quality and a flat base for your parquet.
