Specialist Damp Surveys, Mould Treatment & Timber Preservation Across South Wales
Nordic Damp Proofing provides professional damp surveys, damp proofing, mould treatment, timber preservation and property restoration services across Cardiff and the wider South Wales area.
With a local Cardiff office at 14 Museum Place, City Centre, Cardiff, CF10 3BH, our team is well placed to support homeowners, landlords, letting agents, property managers and commercial clients across the city.
A damp survey is the best starting point if you are unsure what is causing moisture inside your property.
Damp can appear in many different ways. You may notice mould on walls, damp patches after rain, peeling paint, damaged plaster, musty smells, condensation on windows or soft timber. However, the visible signs do not always reveal the true cause.
Our surveyors inspect the property carefully before recommending treatment, helping to make sure the right solution is used from the start.
We provide damp surveys and treatment services across South Wales, South East Wales and nearby areas, including Cardiff, Newport, Penarth, Cowbridge, Chepstow, Monmouth, Abergavenny, Bridgend, Caerphilly, Pontypridd, Barry, Brecon, Llandeilo, Llantwit Major, Usk and Swansea.

South Wales has a wide range of property types, from older terraced homes and stone cottages to modern houses, flats, rental properties, commercial units and buildings exposed to coastal or valley weather conditions.
Because of this mix, damp problems can vary from property to property. Older homes may be more vulnerable to failed damp-proof courses, porous masonry, ageing mortar and poor ventilation. Flats and rental properties may suffer from condensation and mould where airflow is limited. Coastal and exposed properties may be affected by wind-driven rain, humidity and water ingress through external defects.
Properties across South Wales can suffer from damp for different reasons depending on where they are located. A terraced house in Cardiff may have a very different issue to a coastal property in Barry, a valley home in Pontypridd or an older stone property near Monmouth or Abergavenny.
That is why Nordic Damp Proofing starts with a proper inspection. We look at the building, moisture patterns, ventilation, external defects and signs of timber damage before recommending any treatment.
Common problems we help with include rising damp, penetrating damp, condensation, black mould, wet rot, dry rot, woodworm, water ingress and basement waterproofing issues.
Rising damp is often found at low level on ground floor walls. It happens when moisture is drawn up from the ground and into the wall structure.
In South Wales, this can be seen in older terraced homes, stone cottages, converted buildings, commercial premises and properties where the original damp-proof course has failed or been bridged.
You may notice:
Before recommending treatment, we check whether the issue is actually rising damp or whether it is being caused by another problem, such as condensation, penetrating damp, high ground levels or poor ventilation.
Black mould is one of the most common reasons people contact us across Cardiff, Newport, Swansea, Bridgend, Barry, Caerphilly and surrounding towns.
It is often linked to condensation, which forms when moisture in the air settles on colder surfaces. This is common in bathrooms, bedrooms, kitchens, window reveals, wardrobes, corners of rooms and behind furniture.
Condensation can be worse in properties with:
Cleaning mould may make the room look better temporarily, but it does not fix the cause. We can inspect the property and advise whether the issue needs mould treatment, ventilation improvements, damp repairs or a combination of solutions.
South Wales properties can be exposed to heavy rainfall, wind-driven rain and changing weather conditions. If the outside of the building has defects, water can enter through walls, roofs, chimneys, gutters or damaged finishes.
Penetrating damp may be caused by:
This type of damp is often worse after rain and may show as staining, damp patches, bubbling plaster, peeling paint or a cold, musty smell inside the property.
The key is to stop the water getting in, not just redecorate over the internal damage.
South Wales has a varied mix of property types and environments. Coastal homes around Barry, Penarth, Swansea and Llantwit Major may deal with salt air, wind-driven rain and higher humidity. Valley areas such as Pontypridd, Caerphilly and Bridgend can experience damp linked to rainfall, airflow, shaded walls and older housing stock.
Older properties in Cardiff, Newport, Chepstow, Monmouth, Abergavenny, Usk and Brecon may have solid walls, ageing masonry, older timber, failed damp-proof courses or previous repairs that have trapped moisture inside the building.
Because each property is different, we do not take a one-size-fits-all approach. Our surveyors look at the age, construction, location and condition of the building before recommending the most suitable treatment.
Moisture can also affect the timber inside a property. If damp is left untreated, it can create the right conditions for timber decay and insect attack.
We can inspect and advise on:
Timber problems are often linked to an underlying moisture issue, so it is important to deal with the source of damp as well as the damaged timber itself.

The first step is to identify why the mould is growing. Mould is usually caused by condensation, poor ventilation, excess moisture, cold surfaces, water ingress or an underlying damp issue.
Cleaning mould may remove the visible growth for a short time, but it will often return if the moisture source is not fixed. A damp and mould survey can identify the cause and recommend the correct treatment.
Older properties can be more vulnerable to damp where damp-proof courses have failed, walls are solid, ventilation is poor, external ground levels are high or previous repairs have trapped moisture inside the building.
A professional survey helps make sure the recommended treatment is suitable for the age and construction of the property.
Yes. We can help with damp and mould issues in coastal properties, including homes affected by wind-driven rain, salt air, condensation, humidity and external water ingress.
