What are the disadvantages of pergo flooring?

Disadvantages of Pergo flooring include not being fully waterproof for laminate line, hard and cold underfoot, noisy without good underlayment, cannot be refinished, and can swell with moisture, though Pergo Extreme LVP addresses some issues. Pergo laminate, which is HDF high-density fiberboard core, is not 100 percent waterproof like luxury vinyl plank, so it can swell, warp, and be damaged if water sits on seams, making it unsuitable for bathrooms, laundry rooms, and basements with moisture, unlike Pergo Extreme LVP which is waterproof. Pergo laminate is hard and cold underfoot compared to carpet, and can be noisy with clicking sound when walked on if underlayment is thin or poor quality, requiring good underlayment for sound absorption. Pergo laminate cannot be sanded and refinished like hardwood, so when worn, it must be replaced, not refinished. Pergo laminate can be slippery when wet and shows scratches more on dark colors. Pergo laminate installation requires flat subfloor within 3/16 inch over 10 feet, otherwise it can flex and break click-lock. Pergo Extreme LVP, while waterproof, has disadvantages like being softer than laminate and can dent with heavy furniture. Overall, Pergo laminate disadvantages are water sensitivity, hard underfoot, and not refinishable, while Pergo Extreme LVP has fewer disadvantages but can dent.
