Loose or hollow sounding parquet blocks: Dutch repair options for 2026

By Thomas Bakker · Updated July 2026 · 5 min read

Causes of hollow parquet blocks in Dutch homes

Hollow or loose parquet blocks are a common problem in the Netherlands, especially in older homes. The sound occurs when the wood loses its grip on the subfloor. This can happen due to moisture changes, a poorly prepared subfloor, or the natural aging of the adhesive.

In many Dutch houses with concrete floors, the adhesive dries out after 20 to 30 years. Another cause is underfloor heating that was not installed correctly. If the heat-up protocol is not followed, the wood can expand and contract too much.

Martijn de Wit Vloeren, a family business since 1995, sees this regularly in their showrooms in Schagen and Oostzaan. They advise that a professional inspection is the first step to find the real cause.

How to identify loose parquet blocks yourself

You can often identify hollow blocks by walking on the floor and listening for a clicking or hollow sound. Another method is to tap the blocks with a coin or a wooden stick. A solid block makes a dull thud, while a loose block sounds hollow.

Check if the blocks move when you press on them with your foot. In the Netherlands, many homeowners notice the problem after a dry winter or when they switch on underfloor heating. If the problem is limited to a few blocks, a local repair is possible.

If large areas are hollow, a full solution is needed. Martijn de Wit Vloeren assesses the floor during a free quotation and gives advice without sales pressure. They explain exactly what is happening and what options you have.

Repair option 1: injecting glue into hollow parquet blocks

For small areas of loose blocks, injecting glue is a quick and cost-effective method. A professional drills a small hole in the block, injects a special flexible adhesive, and then presses the block down with weights. This method works well if the subfloor is still solid and the blocks are not damaged.

The cost for this repair in the Netherlands ranges from EUR 30 to EUR 60 per square meter, depending on the number of blocks. Martijn de Wit Vloeren uses their own patented S5 Coating after the repair to protect the surface. This coating has five transparent layers that are scratch resistant, UV resistant, and moisture resistant.

For eco-conscious homeowners, they also offer Bioscoating, a finish based on plant oils. Injection is not a permanent fix if the entire floor has lost its bond, but it works well for localized problems.

Repair option 2: replacing individual parquet blocks

If some blocks are damaged, cracked, or completely loose, replacement is the better option. The professional removes the damaged block, cleans the area, and installs a new block of the same wood type and size. For oak floors, which are the core specialism of the specialist, matching the color and grain is important.

They have a large stock of oak blocks, including herringbone, Hungarian point, and block patterns. The cost for replacing blocks in the Netherlands is higher, typically EUR 80 to EUR 150 per square meter, because every block is handled individually. After replacement, the floor is sanded and finished to create a uniform look. the specialist offers this service throughout the Netherlands, with their own in-house fitters.

They also have a tile studio if the floor is a mix of wood and tiles.

Repair option 3: full relaying of the parquet floor

If more than 30 percent of the blocks are hollow or if the subfloor is uneven, a full relaying is the best long-term solution. The old blocks are removed, the subfloor is prepared, and then the blocks are reinstalled with a new, strong adhesive. This process also allows you to change the pattern or add underfloor heating. the specialist provides advice and installation for underfloor heating, including the heat-up protocol.

The cost for a full relaying in the Netherlands ranges from EUR 100 to EUR 200 per square meter, depending on the complexity. For a unique floor, they offer their Piece Unique bespoke line, which creates exclusive custom designs. After relaying, the floor gets a new finish, often the S5 Coating for extra durability.

This option is the most expensive but restores the floor to like-new condition.

Preventing loose parquet blocks in the future

Prevention is better than repair. In the Netherlands, the climate changes between wet winters and dry summers, which affects wood. Keep the indoor humidity level between 45 and 60 percent.

Use a humidifier in winter and a dehumidifier in summer. If you have underfloor heating, follow the heat-up protocol carefully. Never increase the temperature by more than 2 degrees per day. the specialist includes this protocol in their underfloor heating installations.

They also advise on the right wood thickness and block size for your specific situation. Regular maintenance, such as cleaning with a damp mop and avoiding excess water, extends the life of the floor. With proper care, a parquet floor can last for decades without hollow blocks.
