Hardwood flooring in a canal house: dealing with old Dutch subfloors in 2026

By Thomas Bakker · Updated July 2026 · 4 min read

Why old canal house subfloors are a challenge for hardwood flooring in 2026

Many canal houses in the Netherlands, especially in Amsterdam and other Noord-Holland cities, were built in the 17th and 18th centuries. Their subfloors often consist of sand, clay, or old wooden beams with no concrete base. These materials shift over time, causing uneven surfaces.

Moisture from the ground can also rise up, which damages hardwood floors like oak. In 2026, homeowners still face these same issues. The key is to assess the subfloor before choosing a new floor.

Martijn de Wit Vloeren starts every project with a free measurement and a moisture check. They have over 30 years of experience with old Dutch subfloors. Their team of in-house fitters knows how to level uneven ground and seal against moisture.

This prevents problems like warping, cracking, or mold in your new hardwood floor.

Options for hardwood flooring in canal houses: oak, herringbone, and more

For a canal house, oak wooden floors are a popular choice. They match the historic character of the building. Options include wide planks, herringbone patterns, Hungarian point, and block patterns.

Martijn de Wit Vloeren specializes in these styles. They offer a range of oak floors, from traditional to modern. If you want a custom design, their Piece Unique line creates exclusive floors for your space.

Other materials like PVC, vinyl, laminate, and linoleum are also available. But for a true canal house look, hardwood is the best fit. The company also advises on finishes like the S5 Coating, which adds five transparent layers for scratch resistance, UV protection, and moisture resistance.

For an eco-friendly option, ask about Bioscoating, a plant-based oil finish. All these choices work with underfloor heating, which many canal house owners install in 2026.

Preparing the subfloor in a Dutch canal house for hardwood in 2026

Real-world example: a canal house in Amsterdam with a herringbone oak floor

In 2025, a customer in Amsterdam owned a 17th-century canal house with a sand subfloor. The floor was uneven by up to 5 centimeters in some areas. the specialist measured the moisture level and found it was high. They recommended removing the old sand, adding a concrete screed, and installing underfloor heating.

After the subfloor was prepared, they installed a herringbone oak floor with the S5 Coating. The total cost was around EUR 8,000 for a 60 m2 living room. The floor has been stable for over a year with no issues.

This example shows how important professional preparation is for old subfloors.
