Owner and installer responsibilities

Wood is a natural material that possesses certain unique characteristics. Sustainable Lumber Co. manufactures in accordance with the highest standards of quality and craftsmanship. Standard trade practice allows up to a 5% margin of error for natural imperfections and manufacturing defects.

The following requirements are the responsibility of the floor’s owner, even if the owner is absent at the time of installation:

  • Prior to installation, the installer and owner must ensure that the work environment and walls and ceilings meet or even exceed the minimal specifications listed in the Sustainable Lumber Co. installation guide.
  • Prior to installation, the installer and owner should conduct a final inspection of the grade, color, manufacturing, and finish quality of boards to ensure that the floor conforms to the purchased product.
  • During installation, the installer should not use boards that raise doubts about the grade, color, manufacturing quality or finish. Sustainable Lumber Co. will replace only defective boards, not exceeding the 5% margin of error allowed by industry standards.
  • Sustainable Lumber Co. shall in no case be liable for the installer’s lack of judgment or poor quality of installation.
  • Once installed, all boards are considered as having been accepted by the installer and owner, even if the owner is absent at the time of installation.

Exclusions due to certain inherent properties of wood

Wood expands and contracts according to variations in humidity. Even if the flooring is properly installed, narrow gaps and slight distortions can occur. Moreover, exposure to light alters the color of all wood species. Areas covered with area rugs, furniture, construction paper, and any other light-blocking objects will result in color variations.
