Why is Pergo Flooring Cupping and Warping

Pergo Flooring Cupping and Warping after only 5 Years since Installation

By Mark J. Donovan

Question: I had Pergo flooring installed in my home about 5 years ago and I have recently noticed it cupping and warping. The company that installed the Pergo flooring offered a 15 year warranty. I am now debating contacting the company to demand they replace the Pergo flooring. Do you have any ideas why my Pergo flooring is cupping and warping and do you think I should contact the Pergo flooring installation company?

Answer: Pergo flooring is a particular brand of laminate flooring and laminate flooring is susceptible to moisture. Consequently if the Pergo flooring was installed on a subfloor that has moisture problems, or that is susceptible to moisture problems this could cause the Pergo flooring to cup and warp.

For example installing Pergo flooring in a basement, laundry room or bathroom is usually not a wise idea.

Concrete basement floors can frequently have high moisture content and this moisture can wick its way into the Pergo flooring. The same situation is true for bathroom and laundry rooms, except the moisture is usually associated with water spills.

If the Pergo flooring, or laminate flooring, was installed on a subfloor that was not first tested for moisture content, then you may have grounds for contacting the Pergo flooring installation company and demanding it be replaced.

They should have tested the subfloor for moisture levels prior to installing the Pergo flooring. However, if you knowingly had the Pergo flooring installed in a potentially wet environment, it is unlikely that the Pergo flooring installer will honor the product warranty.

Another potential cause for Pergo flooring cupping and warping is not allowing for expansion of the flooring.

When installing Pergo flooring, or laminate flooring, it is important that expansion of the material be accounted for. This means that when installing Pergo flooring, approximately a half inch apron (or gap) should be left around the perimeter of the Pergo floor to allow it to expand, or breathe if your will.

The Pergo flooring should not be installed such that it butts up tightly against the walls. Instead, the Pergo flooring should be brought up to within about ½ inch of the wall, and then baseboard trim installed over it to hide the gap.

If the Pergo flooring installation contractor did not include this gap during the installation, then this could account for the Pergo flooring cupping and warping.

You can check for this by removing a section of baseboard trim on a couple of sides of the room and see if there is a gap. If there is not, then you should contact the Pergo flooring installation contractor and have them come out and take a look.

This would be a clear sign that the contractor did not install the Pergo flooring correctly and thus should be replaced under your warranty.
