Mould That Keeps Coming Back
Why cleaning is not the fix, and how to find the moisture feeding it.
Mould returns because its water source was never addressed. Cleaning removes the growth; correcting the moisture removes the cause.
What to check yourself
- Photograph affected areas before cleaning
- Note whether it tracks a corner, window or baseboard line
- Record any recent repairs in those areas
Likely causes
- An active leak behind a finish
- Elevated humidity and poor ventilation
- Envelope or below-grade entry
What the investigation does
- Find the source with moisture and thermal methods
- Correct the source before remediation
- Verify with a follow-up scan

Quick answers
What should I do first about this?
Find the source with moisture and thermal methods
Can this be fixed without opening everything?
In most cases the investigation narrows the target before any finish is opened. Small access points are sometimes needed to confirm a finding, and that is discussed before anything is opened.
