Study Shows Window Replacements Reduce Lead Dust Levels

NCHH released a new study that showed significantly lower amounts of lead dust in homes that had window replacements. The study evaluated homes that either replaced or repaired windows 12 years ago to determine which strategy resulted in lower lead dust levels on floors and window sills. The results showed that dust levels were 41% lower on floors and 51% lower on window sills in homes with replaced windows than in homes with repaired ones. When considering both energy efficiency and home improvement, homeowners can save almost $2,000 on window replacements, the study shows. Although lead-safe window replacement is an important element of lead hazard control, weatherization, renovation and housing investment strategies, window replacement alone cannot render a home lead-safe. In fact, NCHH encourages homeowners to check all lead sources, including deteriorated lead paint on the exterior of homes, lead dust on floors and lead in soil. For more information, visit nchh.org.
