Mould Testing and Sampling in Hull

When testing is worth it

• You can smell it but can't see it. A musty smell after a leak or flood, with no visible growth, can point to mould in a floor void or behind units.
• Someone's health is affected. Asthma getting worse, or a doctor asking what's in the home, is a good reason to measure rather than guess.
• A dispute needs evidence. Between a tenant and landlord, a buyer and seller, or you and an insurer, test results carry weight that photos don't.
• After remediation. To show a flood-damaged or mould-cleared room is back to normal before it's lived in again.

What a test can and can't tell you

Air samples compare spore levels inside with the air outside at the same time, which shows whether the house has a problem the outdoors doesn't. Surface swabs or tape lifts identify what's growing on a particular patch. Neither finds the source of the moisture, which is the part that needs fixing, so we pair any test with moisture readings.

Results come back from the lab in a few days. They are a snapshot, and levels change with the weather, heating and how recently the room was disturbed.

When you don't need it

If mould is visible, the cause is obvious (a leak you've just had, or condensation on a cold north wall) and nobody is unwell, spend the money on fixing the damp instead. We'll say so. Plenty of older Hull terraces get condensation mould every winter, and a test won't tell you anything about that a look and a hygrometer can't.

Mould after flooding in Hull

After a flood, especially one involving sewer water, hidden mould under floors and inside walls is common. That's where testing before you move back in can be worth it, alongside a proper drying record. For the removal itself, see mould remediation.

If the mould followed a leak, our water damage cost estimator prices the drying and repairs as well as the mould removal.
