DAMP & MOULD SPECIALIST · LONDON
Mould around windows
and cold walls.
Mould on window reveals, in bedroom corners or behind curtains often returns after wiping. We assess the affected surfaces, condensation and airflow to understand what is keeping those areas damp.
UNDERSTANDING THE PROBLEM
Cold spots can stay
damp for longer.
Window glass, reveals and parts of external walls can be colder than the surrounding room. Moisture from indoor air may settle there, especially where curtains or furniture restrict air movement.
Condensation is a common explanation, but gaps around windows or another source of damp can create similar damage. We check the location and pattern before recommending treatment or changes to ventilation.
Tell us whether the glass is also wet and whether marks worsen after rain. The frame, seal, reveal and nearby wall can each offer different clues. Condensation and ventilation checks address indoor moisture; rainwater entry checks may be needed where the evidence points outside.
DURING THE VISIT
What we check.
Frames, seals, reveals and nearby wall surfaces
Cold corners and areas behind curtains or furniture
Repeated condensation and signs of restricted airflow
Possible water entry around the window opening
HOW IT WORKS
Check the surface
before treating it.
Inspect the mould pattern
We look at exactly where the mould forms and ask when the surrounding surfaces become wet.
Check moisture conditions
The inspection considers cold surfaces, ventilation and possible external entry points.
Plan treatment and prevention
We discuss the affected surfaces and changes needed to reduce repeated wetting.
BEFORE YOU BOOK
Questions about
this service.
Why does mould return around the same window?
The surface may still be getting wet through condensation or water ingress. Cleaning the mould does not change those conditions.
Can new windows still get condensation?
Yes. Moisture can condense on cold surfaces in well-sealed rooms if ventilation and moisture management are not adequate.
Should I replace the window?
Not automatically. An assessment can help distinguish a window defect from condensation or another moisture issue before you commit to work.
