Master Builders Queensland (MBQ) says flood-hit residents can visit its website to search for licensed contractors.
There have been concerns about a possible shortage of builders in some areas.
MBQ spokesman Michael Hopkins says it is important to ensure builders have the proper credentials.
"What we'll see happening is that as well as the local builders obviously doing a lot of the works, there'll be builders come from around Queensland to help out, which is what we've seen happen in these sorts of situations in the past," he said.
Residents and builders in flood-affected areas have been urged to be wary of the dangers of mould.
He says houses must be left to properly dry out before repair works can begin.
Mr Hopkins says safety precautions should be taken.
"Just to make sure safety equipment's being used ... use the proper cleaners and if people are allergic make sure they're using ventilators, masks and the like to make sure they're protected," he said.
