Forum Title: Pergo expansion ?
Hi, I just put in a pergo xp floor in my sunken family room (sunken by about 6). I left the appropriate expansion space around the perimiter of the floor. I also screwed Pergo to what would be considered a stair riser. Going up from the family room to the kitchen. The pergo is installed flush to the floor and under stair nosing on the top. A few hours after I finished the installation I realized I left no expansion gaps for the stair riser. Should I remove the pergo, rip a quarter of an inch of the bottom and then reinstall with some expansion room on the top and bottom. It would be a moderate job to do so. My answer to my own question is Yes. Thanks, Mike

I can't imagine it causing a problem Mike, being that a riser is usually about 6-7 high. What measurable expansion could there be in 7 inches. I may be wrong though. It's happened before.

FWIW: I would wait to see if anything happens. I doubt it could with such small pieces.
