Fifteen families will have their homes retested out of an "abundance of caution," according to Lincoln.
The mold inspector, who works for Frohling and Robertson, has since then gotten the proper licensing paperwork and has continued to test in other homes.
Lincoln also announced today that they will have independent industrial hygienists inspect every home after work is done by subcontractors.
The move comes after they were alerted by one of their residents to poor work quality done in their home.
Lincoln says they want to make sure all contracted work holds up to their standards of quality.
