Champion Windows installed a large first floor living room window at our home in Columbia, SC, in…read more2019. We believe the window began leaking within three years, leading to catastrophic damage, including moldy carpet and interior studs, a rotting foundation beneath the window, destroyed drywall beneath the window, large cracks beside and above the window on both the first and second floors due to the destroyed foundation, and a back door that no longer shut properly. We first noticed the problems in 2024, when we spotted mold growing in the carpet beneath the window, and over the next few months discovered extensive additional damage and reached the obvious conclusion that the window was leaking. Champion, alerted to these problems in early 2025, and despite the firm's "lifetime guarantee," made absolutely no effort either to understand the problem or to fix it. Instead, after an ineffectual visit to our home by several executives (they took pictures of the cracks), Champion brought in their insurance company, Liberty Mutual, who hired an engineering/consulting firm, Rimkus, to investigate the leak. The end result was a series of increasingly bizarre claims in which everyone and everything was blamed except for the window. The rot was due to mold climbing up from the ground, we were told at first, after which Rimkus insisted that all the leaking was due to a March 2025 re-siding project completed years after leaking began. No party ever performed true forensics, e.g. removing the drywall and testing the window for leaks, so we had to do so ourselves, creating a video that clearly showed that when water was poured on the exterior windowsill, it quickly ran down the internal wall studs and soaked the wood foundation. Even after we provided this video as part of the exhaustive documentation Liberty demanded, any responsibility for the problems on Champion's part was completely rejected by Liberty. In the end, we had to pay out of our own pockets to replace moldy carpet, shore up the rotting foundation and studs beneath the window, replace the window, repair and repaint the cracked and wet drywall, rehang an exterior door twice, and make other repairs, some of which are ongoing. (NOTE: All details of this complaint are thoroughly documented and have been shared with the listed parties, none of whom have offered any remedy)
