Mould in your home. What to do, in order
Mould is a moisture problem wearing a stain costume. Here’s the honest decision path: when testing is worth paying for, what it should cost, and how to act. Whether you own the place or rent it.
Do you actually need testing?
Skip the inspection
A patch on bathroom grout with an obvious cause: fix the ventilation habit, clean it, watch it. Spend the inspection money on a dehumidifier if humidity is the culprit.
Get an inspection
Mould that returns after cleaning, appears away from wet areas, smells musty without visible growth, or follows a leak or flood. The cause is the question, and that’s what a real inspection answers.
Renting?
If it looks building-related (leaks, rising damp, no working extraction), the fix may be the landlord’s to fund. See the renter path below before paying anyone.

Renting? Read this fork first
If the problem looks building-related, your state’s rental standards may put the fix on the landlord, not your wallet. Two tools:
- The complaint letter template. Structure + the evidence that makes it work
- Minimum standards, state by state. What’s law where you live
