Why attics grow mould
Warm, moist air from the house leaks into the attic and condenses on cold roof sheathing in winter. Blocked soffit vents, bathroom fans venting into the attic and air leaks around fixtures make it worse. The result is dark staining and growth on the sheathing and rafters.
How we remediate it
We work in full PPE, protect the living space below, clean or remove affected material, HEPA-vacuum the area and apply an antimicrobial where appropriate. Then we verify the result before we leave.
Fixing the cause
Remediation without fixing the moisture source means the mould comes back. We point out the likely cause — ventilation, bath fan ducting, air sealing — and tell you plainly what needs to change.

Questions about this kind of job
Is attic mould dangerous?
It is usually above the living space, but spores and odours can reach the home through air leaks and fixtures. It also signals a moisture problem that can damage the roof deck over time.
Does home insurance cover attic mould?
Often not when it comes from long-term condensation or ventilation, but it may be covered when it follows a sudden event such as a roof leak. We document what we find so you can ask your insurer.
