He said he's also "concerned that we are not seeing cases where we could help, and want to investigate further into this issue".
He said he wants to use new powers to look "in-depth at the response of social landlords to damp and mould issues".
"I want us to make far-reaching recommendations to promote greater understanding and learning, helping landlords develop their approach to the benefit of residents."
An initial review of case data found there had been a "high rate" of "maladministration" on cases that feature damp and mould over the last two years.
It said the fact that £68,000 in compensation had been ordered in same period showed "significant impact on residents in some cases".
