Lowe’s, the nation’s No. 2 home improvement chain, is offering as much as $100,000 in cash to customers who can prove they bought drywall from the retailer and also prove that it caused at least $4,500 in damages. The contaminated drywall releases high amounts of sulfur gas, which can corrode copper wiring and cause air conditioners and other electrical appliances to fail. Some homeowners have also complained that the drywall has affected their health by triggering respiratory problems, bloody noses and headaches.
