Damp & Mould Cleaning & Treatment

A three-stage initial damp and mould cleaning and treatment process, including a discounted survey and written report.

Visible mould is a sign that a surface has stayed damp enough for growth. Careful cleaning and treatment can improve the affected area, but lasting improvement also depends on understanding why excess moisture is present.

We tailor the treatment to the material, extent and underlying cause. A coating or chemical treatment is not presented as a universal cure for a leak, cold surface or inadequate ventilation.

When this service may help

Black or coloured mould on walls, ceilings, windows or sealant
Mould that returns after ordinary cleaning
Local staining or a musty smell in one room
A recently identified moisture source that needs the affected area made good

What we look at / do

The affected material and extent of visible growth
Whether moisture, ventilation, cold surfaces or a building defect need separate action
Surrounding finishes and areas that need protecting
Aftercare considerations once treatment is complete

Important to know

Cleaning or treatment does not repair leaks, remove cold bridges or create ventilation. Hidden mould and moisture behind finishes cannot be confirmed without suitable access. We do not provide medical diagnoses or health advice.

What happens next

Tell us where the mould is and whether it has returned. We can advise whether a survey, a local treatment or work on the moisture source is the right first step.
