No one wants wood floor cupping, but you can help customers find solutions to their floor cupping problems.
Hardwood floor cupping is caused by a moisture imbalance in the flooring. It is a condition when a wood floor gains more moisture on the underside of the board causing the boards to swell on one side, giving the outside edges of the plank a raised look while the center remains flat. This U shape can cause gaps to occur between the planks, leaving many homeowners in a state of worry and concern.
While all wood floors can be affected by cupping, the wood floor professional can help alleviate customer concerns and find solutions to serious cupping issues. Be sure to give your customers this important information regarding wood floor cupping.
Floor cupping can be a seasonal issue.Seasonal temperature and humidity fluctuations will have an effect on wood floors. It is natural for wood floors to expand and contract throughout the year, and seasonal Relative Humidity swings can have a big impact here. Remind customers that minor cupping may be due to seasonal changes and that this kind of cupping usually disappears on its own when the Relative Humidity stabilizes.
Floor cupping can be a moisture issue.If you suspect that customers are experiencing wood floor cupping outside of seasonal effects, then a different moisture issue needs to be identified. First, make sure customers have stable humidity conditions in their homes. Help them troubleshoot any potential HVAC issues. Remind customers to use humidifiers/dehumidifiers to help stabilize the relative humidity levels in their home in the range of 40% - 60%.
Floor cupping can be a maintenance issue.If moisture levels in the home are stable and wood floor cupping is still an issue, the source of moisture still needs to be identified. Check with customers to see if other maintenance issues could be the culprit: leaking pipes, appliances, subfloor issues or foundation issues. Remind customers that finding the source can take more time than they might expect, and other professional help may be needed.
How to prevent floor cupping.If your customers are in the process of getting floors installed, remind them of some simple ways to prevent floor cupping:
