Mould removal in Cardiff
Simpled Services provides specialist mould removal in Cardiff - removing black mould and condensation mould from the city's Victorian terraces, student houses and rented homes across South Wales, with a free assessment and a 12-month guarantee.
Why Cardiff homes suffer from mould
Cardiff's mild, wet coastal climate and rows of Victorian terraces - especially the dense student housing in Cathays and Roath - create ideal conditions for condensation. Solid walls, high rainfall and intensively occupied lets mean indoor humidity stays high and black mould appears on cold walls and around windows.
We treat mould across Cardiff, from Cathays and Roath to Canton and Grangetown, removing it safely and fixing the moisture problem behind it.
Our mould removal process
A proven four-step process that treats the cause, not just the symptom - so the mould stays gone.
- 1
Assess
We inspect the affected areas and find the moisture source driving the mould - not just the visible growth.
- 2
Contain
We seal off the area so spores don't spread to clean rooms while we work.
- 3
Remove
We safely treat and remove all mould using professional-grade methods, then anti-microbial protect the surface.
- 4
Restore & prevent
We repair any damage and advise on ventilation and damp control so the mould doesn't come back - backed by our 12-month guarantee.
How we approach mould removal
Find the cause, treat affected surfaces, address the moisture source and refinish where needed.

Why untreated mould is a real risk
Mould releases allergens and mycotoxins that can trigger coughing, wheezing, throat and skin irritation, and asthma attacks - a particular danger for children, the elderly and anyone with a respiratory condition. Left alone, it also damages plaster, timber and decor, turning a small problem into an expensive one.
Acting early protects both your health and your property. We deal with mild surface mould and severe, widespread infestations alike.
