This quality laminate flooring is guaranteed for 25 years not to wear through or stain. This guarantee applies only to the original purchaser and proof of purchase is required for all claims. The guarantee is for replacement or refund of the laminate material only, no labor. The guarantee does not cover chipping (laminate will chip if sharp objects are dropped on it), warping (laminate will warp if excessive moisture gets into the boards) or bridging (which is caused by insufficient expansion spacing). We will not consider any claims for these problems. Claims for wear must show a minimum dime size area. This guarantee is pro-rated based on the amount of time the floor has been installed. Humidity should not be allowed to drop below 30% as it may cause gapping.
