Permabois’s 25-year warranty

PERMABOIS offers expertise, know-how and a finishing process that ensures constant quality and durable products that meet your expectations.

PERMABOIS floors come with a 25-year warranty in residential use against any manufacturing defect. The warranty is limited to the original buyer. Oil durability cannot be guaranteed, since it depends on the maintenance provided by the floor’s owner. If maintenance is performed as described in the installation booklet and using the recommended product, consumers will be able to benefit from their floor without needing to have it sanded.

Nevertheless, wood remains a natural product. An imperfection rate below 5% is considered acceptable according to industry standards (NWFA). Imperfections can be the result of natural causes or a manufacturing defect.

Manufacturer’s liability

Permabois Bois Huilés Inc. will repair or replace defective planks, at its discretion.
When a plank is installed, however, it is considered accepted by the owner/installer. Before proceeding with plank installation, the installer and/or owner is responsible for a final inspection as regards category, manufacture and plant-made finish. The owner/installer must make a reasonable selection and reject or cut wood planks that show an obvious defect, no matter its cause. The warranty applies to defective products that exceed 5% of the total quantity in square feet purchased by the client (excluding losses caused by cutting the planks at installation).

The warranty applies only to the product and excludes any other compensation such as, without limitation, any damage to the buildings in which the floor in installed, to the goods found therein, any injury or financial loss, etc.

No retailer, agent, wholesaler, distributor, nor salesperson is entitled to modify the terms of this warranty.

The manufacturer fully supports its product. If a problem was to occur, however, the manufacturer will solve it on an individual basis to ensure the client’s full satisfaction.


Permabois huilés inc. assumes no liability at the warranty’s expiry, and will provide no compensation:

  • For damages other than those listed in the “MANUFACTURER’S LIABILITY” section above, and herein excludes the coverage of any consequential damage of any nature
  • Where the ¾-inch floor is glued
  • Where the floor is installed on a concrete slab, a radiant subfloor, or if the subfloor doesn’t meet the installation standards recommended by Permabois Bois Huilés Inc.
  • When a slight difference exists between the sample and the floor
  • If damages are caused, in whole or in part, without limitation, by a change in the humidity rate, by dryness or lack of heating

Customer liability

Humidity is wood’s worst enemy. The rigorous control of ambient humidity in the premises, of the concrete covering, of the subfloor’s base, of the subfloor, and of finishing floor planks is indispensible for successful installation.

PERMABOIS BOIS HUILÉS INC. declines liability regarding any kind of defect in cases where the installation did not conform to the standards, recommendations and guidelines below.

Procedure prior to the installation of the finish floor

To prevent the occurrence of undesirable humidity conditions that could lead to the alteration of the finish floor, a minimum waiting period of 30 days following the installation of the beds (concrete covering, joists, etc.) on which the subfloor or floor will rest must be respected to allow the evaporation of humidity prior to delivery and installation of the finish floor. In winter, maintain the temperature near the occupation standard of 20°C for at least 7 days prior to delivery. In summer, ensure adequate ventilation of the premises to allow humidity to escape from structural elements.

The humidity contained in the subfloor, beds and/or concrete covering must be below 12 to 14%. The difference between the subfloor and floor cannot be above 4%.

Procedure following the installation of the finish floor

  • The use of PERMALUSTRE, a product which serves to preserve the flooring finish in high-traffic areas, is mandatory.
  • Ambient humidity must be maintained at between 40 and 55%, and temperature at 20°C.
  • Maintain an ideal humidity rate in winter using a humidifier if necessary.
  • In areas where the finish floor is located above a heating appliance or non-insulated conduits, install a fire-retardant insulating material or a thermal-insulation panel between joists.
  • Installing the finish floor over a radiant-heating system is not recommended. Gaps between some planks and/or springing of planks could ensue.

All essences are offered in plank widths of 3 1/4, 4 1/4 and 5 inches.
