How should expansion joints be managed for hardwood flooring?

Managing Expansion Joints for Hardwood Floors


The installation of a hardwood floor requires meticulous attention to detail, especially concerning the management of expansion joints. At Plancher Deluxe, based in Montreal, we value excellence and precision in every project, whether it's a residential or commercial installation in Laval, Longueuil, South Shore, or North Shore.

The Importance of Expansion Joints

The Vital Role of Joints

  • Damage Prevention: Expansion joints allow the wood to naturally expand and contract in response to humidity and temperature changes, thus avoiding deformations.
  • Floor Longevity: Proper management of joints ensures the durability and stability of the floor in the long term.

Influencing Factors

  • Climate and Humidity: Montreal's changing climate demands special attention to the size and distribution of the joints.
  • Wood Type: Different wood species have varying expansion rates, requiring a tailored approach.

Techniques for Laying and Calculating Joints

Calculation Methodology

  • Precise Measurements: The calculation of the necessary space for expansion joints depends on the size of the room and the type of wood.
  • Industry Standards: We adhere to manufacturers' recommendations and industry norms to ensure quality.

Installation Techniques

  • Precision Laying: Leaving the appropriate space around walls, door thresholds, and around fixtures like columns.
  • Use of Suitable Materials: Selection of threshold bars and transition profiles that allow for adequate expansion.

Practical Cases and Solutions

Residential Examples

  • Old Montreal Houses: Adapting to unique structures and preserving historical aesthetics while ensuring the functionality of the joints.
  • Modern Projects: Integrating expansion joints into contemporary designs for a balance between functionality and aesthetics.

Commercial Applications

  • Large Commercial Spaces: Managing joints over large areas to ensure uniformity and safety.
  • High-Traffic Zones: Reinforcing joints in high-traffic areas for increased durability.

Maintenance and Care Tips

Regular Maintenance

  • Appropriate Cleaning: Using specific hardwood floor cleaning products that do not compromise the integrity of the joints.
  • Periodic Inspections: Regular checks of the joint condition to prevent long-term problems.
