Homeowners may be challenged by the need to find renovators familiar with accessible design issues. People, including family members, housekeepers, visitors, and even renovators, claim to have seen these ghosts. In 2011, Du Bois hosted TEN's renovation reality series, "The Renovators". Individuals can become certified renovators by taking an approved training course. During the 1970s, renovators found the Potters' signatures on the original walls. The show features professional home renovators who purchase older houses to flip for profit. In 1989, the orthodox CNT prevailed in court and the renovators took the name "CGT".
