A damp survey is the best starting point when damp, mould or moisture keeps appearing inside your property.
In Merthyr Tydfil, damp can be caused by several different issues, including hillside ground conditions, poor drainage, ageing brickwork, blocked gutters, damaged pointing, chimney defects, condensation, high external ground levels, failed damp-proof courses or timber affected by long-term moisture.
Where the cause is harder to identify, we may recommend our survey and diagnostic services.

Merthyr Tydfil has a wide mix of property types, including older terraces, hillside homes, valley properties, rental houses, flats, cottages, commercial buildings and modern estates.
Because of this, damp can appear in different ways. Some properties may suffer from condensation and black mould because of poor airflow. Others may have rainwater entering through external walls, roofs, chimneys, gutters or defects around windows and doors. Older buildings may also have low-level damp, salt contamination, timber decay or poor sub-floor ventilation.
Damp problems in Merthyr Tydfil can often be affected by the position of the property. Homes built on sloping ground, close to retaining walls or below raised external land may experience moisture where water is not being directed away from the building correctly.
When rainwater runs towards a property, sits against external walls or collects around the base of the building, damp can begin to appear inside. This may show as staining, low-level damp, damaged plaster, mould growth, salt marks or musty smells in ground floor rooms.
Older terraced homes may also have blocked airbricks, poor sub-floor ventilation, chimney breast damp or previous repairs that make moisture harder to diagnose.
Nordic Damp Proofing looks at how moisture is reaching the property, how it is moving through the structure and what needs to be repaired to stop the problem returning.
For older buildings, our guide on how moisture moves through period properties may be useful. Where wider repair or protection work is needed, we can also advise on restoration and prevention.
Damp near skirting boards or at the base of a wall is often assumed to be rising damp, but the cause should always be confirmed before treatment is chosen.
In Merthyr Tydfil properties, low-level damp may be caused by ground moisture rising through the wall, but it can also be linked to raised external paths, bridged damp-proof courses, leaking pipes, poor drainage, blocked airbricks, condensation at low level or rainwater entering from outside.
Signs that may need checking include salt deposits, crumbling plaster, peeling paint near the floor, soft timber, rotten skirting boards, musty smells and damp marks on ground floor walls.
Where a survey confirms that ground moisture is affecting the wall, we can recommend suitable rising damp treatment. This may include damp-proof course installation or damp-proof injection where suitable.

Black mould is a common problem in homes, flats and rental properties where moisture is building up inside.
It often appears in bedrooms, bathrooms, kitchens, window reveals, wardrobes, cupboards, ceiling corners and behind large furniture. This usually happens when warm moist air settles on colder surfaces and cannot escape properly.
In Merthyr Tydfil homes, mould can become worse where rooms are cold, ventilation is limited, extractor fans are weak, clothes are dried indoors or furniture is placed tightly against outside walls.
Cleaning mould may improve the surface for a short time, but it will often return if the cause of moisture remains. Nordic Damp Proofing can advise on mould removal services, mould prevention services, condensation damp control and humidity control and ventilation.
You may also find our guides on how to stop mould in your home and managing condensation in the home useful.
Damp that becomes worse during or after rain is often caused by water entering from outside.
In Merthyr Tydfil properties, this may be linked to damaged pointing, cracked render, leaking gutters, blocked downpipes, roof defects, chimney faults, poor drainage, exposed walls or water running towards the property from higher ground.
Penetrating damp can show as damp patches, bubbling plaster, peeling paint, water staining, damp chimney breasts, cold wall areas, musty smells or moisture appearing on external-facing walls.
The correct solution depends on finding the route water is using to enter the building. Internal plastering or decorating will not solve the issue if rainwater is still getting through the external fabric.
Nordic Damp Proofing can advise on penetrating damp treatment, repointing services, wall repairs, waterproofing and related remedial work.
Where drainage or ground moisture may be part of the problem, our guide on whether French drains stop damp may also be useful.
Damp in Merthyr Tydfil homes can be linked to hillside ground, poor drainage, older construction, blocked gutters, damaged pointing, chimney defects, condensation, raised external levels or failed damp-proof courses.
Yes. Homes on sloping ground can suffer from damp where water runs towards the building, collects against external walls or affects lower-ground areas. The cause may involve drainage, retaining walls, ground levels, penetrating damp or failed waterproofing.
