Specialist Damp Surveys, Mould Treatment & Timber Preservation in Caerphilly
Nordic Damp Proofing provides professional damp surveys, damp proofing services, mould treatment, timber preservation, waterproofing and property restoration services across Caerphilly and the surrounding South Wales area.
From terraced homes and rental properties to older cottages, commercial buildings, hillside properties and homes around Bedwas, Trethomas, Machen, Llanbradach, Senghenydd and Ystrad Mynach, our team can inspect the issue, find the source of moisture and recommend the right long-term solution.
A damp survey is the best place to start when you are unsure why damp, mould or moisture is appearing inside your property.
A damp stain on a wall does not always mean the same thing from one home to the next. In Caerphilly, the issue could be linked to condensation, rainwater ingress, leaking gutters, defective pointing, raised ground levels, poor ventilation, a failed damp-proof course or timber affected by moisture.
Our surveyors look at the whole property, not just the visible mark on the wall. We check moisture patterns, internal symptoms, external defects, wall condition, ventilation, ground levels and any signs of timber decay.
For more complicated issues, we may recommend our survey and diagnostic services to help identify the source of moisture properly before any treatment is recommended.

Caerphilly has a wide mix of property types, from older terraced homes and stone cottages to hillside houses, rental homes, flats, newer estates and commercial premises.
This means damp can be caused by several different issues. Some homes may suffer from condensation and mould due to poor airflow, while others may have water entering through walls, roofs, chimneys, gutters or external defects.
Damp at low level can be a sign of rising damp, but it should not be assumed without a proper inspection.
In Caerphilly properties, damp near skirting boards may also be caused by raised ground levels, bridged damp-proof courses, blocked airbricks, leaking pipes, poor drainage, condensation at low level or rainwater entering through external defects.
Warning signs can include damaged plaster near the floor, salt marks, peeling paint, damp or rotten skirting boards, soft timber, musty smells and staining on ground floor walls.
If the survey confirms moisture is rising through the wall, we can recommend suitable rising damp treatment. This may include damp-proof course installation or other remedial work depending on the property.

Black mould is one of the most common problems we are asked to inspect in Caerphilly homes. It often appears around windows, behind furniture, in bedrooms, bathrooms, kitchens, wardrobes, cupboards and ceiling corners.
Condensation happens when warm, moist air meets a colder surface. Everyday activities such as showering, cooking, drying clothes indoors and limited ventilation can increase humidity inside the home.
Mould can become worse in rooms with cold external walls, poor airflow, blocked vents, ineffective extractor fans or furniture placed tight against outside walls. Cleaning it may remove the visible growth, but it often returns if the moisture source is still there.
Nordic Damp Proofing can advise on mould removal services, condensation damp control and humidity control and ventilation where required.
You may also find our guides on how to stop mould in your home and managing condensation in the home useful.
Damp that appears after heavy rain is often caused by water entering from outside. Around Caerphilly, this can happen where gutters are blocked, downpipes are leaking, render is cracked, pointing has failed, roofs are damaged or water is collecting against external walls.
Penetrating damp may appear as isolated damp patches, staining, bubbling plaster, peeling paint, damp chimney breasts, cold patches or musty smells in specific rooms.
The important part is finding where the water is getting in. Internal plaster repairs will not stop the problem if the external defect remains.
Our team can advise on penetrating damp treatment, repointing services, wall repairs, waterproofing or related remedial work. Where drainage or ground levels may be part of the problem, our article on whether French drains stop damp may also be helpful.
Damp can cause serious issues when it reaches the timber inside a property. This can include suspended floors, joists, skirting boards, staircases, roof timbers, lintels, door frames and cellar timbers.
Moist timber may become vulnerable to wet rot, dry rot, woodworm and wider timber decay. The correct solution depends on both the condition of the timber and the source of moisture.
Our timber surveys help assess whether moisture is affecting structural or decorative timber and whether treatment is required.
Depending on the findings, we may recommend timber treatment services, wet rot treatment, dry rot treatment or woodworm treatment.
For more information, see our guides on what wet rot is and what dry rot is.
Mould around windows is often caused by condensation. Warm moist air settles on colder glass, frames and window reveals, creating the conditions for mould growth. If the mould keeps returning, the property may need better ventilation, humidity control or a damp inspection.
Yes. Properties on sloping ground can sometimes suffer from damp where water collects against external walls, retaining walls or raised ground levels. A survey can identify whether the problem is linked to drainage, penetrating damp, rising damp or another moisture source.
No. Damp near skirting boards can be caused by rising damp, but it may also be linked to leaks, condensation, bridged damp-proof courses, high ground levels, blocked airbricks or rainwater entering from outside. The cause should be confirmed before treatment.
Damp that becomes worse after rain is often linked to penetrating damp or external water ingress. Common causes include leaking gutters, blocked downpipes, damaged pointing, cracked render, roof defects, chimney issues or water collecting against outside walls.

Yes. We can inspect timber floors, joists, skirting boards, staircases, roof timbers and other timber affected by moisture. Where required, we can advise on woodworm treatment, wet rot treatment, dry rot treatment or timber repairs.
Yes. Older terraced houses can suffer from damp due to solid walls, poor ventilation, ageing gutters, high ground levels, failed pointing, chimney defects or missing damp-proof courses. A survey helps identify the correct cause.
