About Mould Matters.

About Mould Matters.

Card Image

When mould, damp, condensation or water damage appears, you need a straight answer — not guesswork. We inspect the property, identify the source, and set out exactly what needs doing to put it right. Serious enough for a housing association managing hundreds of properties. Human enough for a homeowner standing in front of a damp wall at 9pm.

Our mission & promise.

Most mould gets painted over, wiped down, or treated on the surface — and comes straight back. Our mission is to end that cycle: to deal with the cause, not just the symptom, so the property stays healthy long after we've left.


We know how unsettling it is when mould keeps returning or damp keeps spreading. That's why every job starts with an honest assessment of what's really going on.

What we promise.

A straight assessment — what's there, what's causing it, and what genuinely needs doing. No upselling, no unnecessary works.

Trained specialists on every job — inspection and remediation carried out properly, start to finish.

Clean, respectful work — we treat your property the way we'd want ours treated.

Aftercare that lasts — guidance to keep the conditions that cause mould from coming back.

Our credentials.

Mould Matters is fully insured and works to recognised professional standards across mould inspection, damp surveys, reporting and remediation. Every property is treated as evidence-led — assessed, documented and reported, not just cleaned up.

That means you don't get a short-term fix and a crossed-fingers goodbye. You get a proper diagnosis, a plan that addresses the source, and the guidance to stop the problem returning.
