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.

Choosing a specialist damp company means the cause of the problem is properly investigated before treatment is recommended.
Newport has a wide range of property types, including older terraces, town houses, flats, rental homes, commercial units, modern developments and properties close to rivers, hillsides and exposed weather.
Because of this, damp problems can show up in different ways. Some homes may suffer from condensation and mould due to poor airflow, while others may have water entering from outside through walls, roofs, chimneys or defective gutters.
Common issues we help with include:

Many properties in Newport were built before modern damp control, ventilation and insulation standards. Older terraced houses, converted buildings and rental properties can be more vulnerable to damp where original materials have deteriorated or where later repairs have trapped moisture inside the walls.
Common problems in older Newport properties include failed damp-proof courses, porous brickwork, ageing mortar, defective gutters, poor ventilation, bridged external ground levels and damp affecting timber floors or skirting boards.
Rental properties can also be prone to condensation and mould, especially where rooms have limited ventilation or high moisture levels from everyday living. Landlords may find our guide to damp and mould in rental properties useful when dealing with recurring tenant reports.
A proper survey helps identify whether the issue is lifestyle-related condensation, a building defect, water ingress or a damp-proofing problem.
Rising damp happens when moisture from the ground moves up through walls. This is normally associated with a missing, damaged, bridged or failed damp-proof course.
In Newport, it can affect older homes, converted buildings, extensions and properties where external ground levels have changed over time.
Signs of rising damp may include damp marks near the bottom of walls, crumbling or blown plaster, peeling paint at low level, white salt deposits, damp or damaged skirting boards, rotten timber near ground level and musty smells in ground floor rooms.
A professional survey is important because rising damp can look similar to other issues, such as condensation, leaks, external bridging or penetrating damp.
If rising damp is confirmed, we may recommend rising damp treatment, damp-proof course installation or a suitable remedial system depending on the property. You can also read our guide on how to fix rising damp.
Condensation is one of the most common causes of black mould in Newport homes. It forms when warm, moist air meets colder surfaces such as windows, external walls, ceilings, wardrobes, window reveals and corners of rooms.
Moisture can build up from everyday activities such as cooking, showering, drying clothes indoors and general living. If there is not enough ventilation, black mould can begin to grow.
Mould is often found in bathrooms, bedrooms, kitchens, behind furniture, cupboards and wardrobes, window reveals, external wall corners and ceiling edges.
Cleaning mould may remove the visible growth for a short time, but it will usually come back if the moisture source is not fixed. Nordic Damp Proofing can inspect the cause and recommend suitable mould removal services, condensation damp control or humidity control and ventilation improvements.

Our services include:
You may need a damp survey if you have damp patches, recurring mould, damaged plaster, musty smells, condensation, tide marks, rotten skirting boards or damp that gets worse after rain. A survey helps identify whether the issue is caused by condensation, rising damp, penetrating damp, poor ventilation, water ingress or timber-related moisture damage.
Yes. We cover properties across Newport, including areas close to the River Usk, lower-lying streets, older terraces and nearby neighbourhoods. Properties close to rivers or lower ground can sometimes experience higher moisture levels, but the cause still needs to be checked properly before treatment is recommended.
We cover Newport, Caerleon, Rogerstone, Malpas, Bassaleg, Risca, Bettws, Pillgwenlly, St Julians, Maindee, Lliswerry, Duffryn, Gaer, Magor, Caldicot, Cwmbran, Chepstow and surrounding South Wales areas.
We cover Newport and nearby postcode areas including NP10, NP11, NP18, NP19, NP20, NP26, NP44, NP16, CF3 and CF83.
Yes. We work with landlords, letting agents, property managers and tenants across Newport where damp and mould concerns have been reported. We can inspect the property, identify whether the issue is caused by condensation, ventilation, water ingress or another damp problem, and recommend suitable treatment.
Mould behind furniture or in bedroom corners is often linked to condensation, cold external walls and poor airflow. Furniture placed tightly against external walls can reduce air movement, allowing moisture to collect on cold surfaces. If the mould keeps coming back after cleaning, a damp and mould survey can help identify the cause.
No. Painting over damp may hide the mark for a short time, but it will not stop the moisture source. If the issue is caused by rising damp, penetrating damp, condensation, water ingress or timber decay, the underlying cause needs to be treated before decoration is repaired properly.
Yes. If a basement, cellar or lower-ground room is affected by damp, water ingress or moisture staining, we can inspect the area and advise whether the issue requires damp proofing, structural waterproofing, drainage improvements or basement waterproofing.
Yes. We cover Newport and surrounding areas, and we also support clients across wider South Wales, including Cardiff, Caerphilly, Chepstow, Monmouth, Pontypridd, Barry and nearby towns. Our wider regional page can be found here: Damp Proofing South Wales.
