Mould Removal

Mould is a symptom, not the cause. We treat the conditions that let it thrive in UK homes, so it does not simply grow back.

Damp and mould repair to an internal wall

Mould is never just an eyesore. It is a sign of a hidden moisture problem, and a known health risk. We are specialist contractors across South Wales who find, treat and get rid of mould for good by fixing what is really causing it, whether that is damp, condensation or failed insulation. The result is a home that is safe, dry and healthy again.

The Pro Trade specialist advantage

We do not offer a quick wipe-down. Our approach is built on real technical knowledge and industry-leading qualifications, which is what makes the fix a permanent one.

  • Properly accredited. Our team is approved by both the Property Care Association (PCA) and the Institute of Inspection, Cleaning and Restoration Certification (IICRC), so moisture control and structural drying are done the right way.
  • We find the root cause. With years in damp and timber work behind us, we track down the exact source of the moisture, not just the mould you can see, so it does not simply return.
  • Start to finish. We handle everything from the first inspection and the mould removal through to the structural repairs and the finishing touches, like plastering and decorating.

Our four-step mould removal process

Getting rid of mould for good takes care, the right safety measures and a real plan to stop it coming back. Here is how we do it.

Step 1: Expert diagnosis and survey

Mould only grows where there is too much moisture, so that is where we start. Our PCA-certified technicians carry out a non-destructive survey using moisture meters and hygrometers to measure moisture and humidity accurately, and borescope cameras to see into hidden spots like wall cavities. You get a clear analysis of exactly what caused your mould, whether that is condensation, rising damp, penetrating damp or a structural fault.

Step 2: Safe, certified decontamination

We remove the mould and its spores safely, using professional-grade equipment and biocidal treatments. First we seal off the affected area so spores cannot spread through the rest of your property. Then we apply fungicidal treatments to kill the mould on the surface and deep in the material, clean the area thoroughly, and run air scrubbers to filter spores out of the air and improve the air quality indoors.

Step 3: Fixing the moisture at source

This is the step that separates a specialist from a cleaner. We carry out the repairs that keep the moisture from returning, which might mean improving ventilation with a Positive Input Ventilation (PIV) system, installing a new damp-proof course or repairing penetrating damp from tired masonry or roofing, or safely removing wet, failed cavity wall insulation so the wall can dry out naturally.

Step 4: Full restoration and protection

Once the area is dry and the moisture is dealt with, we put your property back to rights. Where needed we replaster with salt-resistant, breathable materials, then finish with professional painting and decorating so the space looks as good as it did before, or better.

Common causes we fix

The problem
How we fix it
Condensation
Mechanical ventilation (PIV), thermal plastering, and honest advice on managing moisture day to day.
Rising damp
A chemical damp-proof course and proper replastering.

Damage after a flood
IICRC-led clean-up, thorough drying and full mould decontamination.

Do not wait, mould is bad for your health

Left untreated, mould spreads quickly, damaging your property and contributing to respiratory illness. Where growth is ongoing or widespread, UK health and safety guidance says a specialist should step in without delay. Book a survey and we will keep both your health and your property safe.
