Lead Safety

For your family’s safety and peace of mind, Pella® offers EPA-trained sales consultants and installers.

Many homes constructed before 1978 may contain lead-based paint, a potential health hazard for humans and pets. In April 2010, new federal regulations required that renovation, repair and painting projects that disturb lead-based paint in homes, childcare facilities and schools built before 1978 follow specific work practices to prevent lead contamination.
