We Find It. We Treat It. We Stop It Coming Back.
A damp survey helps identify the real cause of moisture before treatment is recommended.
Damp can be deceptive. A small stain on a wall could be linked to condensation, an external leak, a failed gutter, roof damage, raised ground levels, a leaking pipe, poor ventilation, defective pointing, a bridged damp-proof course or moisture affecting hidden timber.
Across Hertfordshire, property types vary widely. There are older cottages, Victorian and Edwardian houses, town centre terraces, converted properties, modern estates, flats, rental homes, commercial premises and larger detached properties. Each building needs to be assessed based on its age, construction, ventilation, ground levels and exposure to moisture.
Our surveyors inspect the property as a whole. We look at internal symptoms, external defects, moisture patterns, ventilation, ground levels, wall condition, rainwater goods and any signs of timber decay.
Where the source of damp is harder to trace, we may recommend our survey and diagnostic services.
Damp in Hertfordshire properties is not always obvious at first. Many homes have been extended, redecorated, insulated or modernised over time, which can sometimes hide early moisture problems until the damage becomes more visible.
Moisture may be trapped behind plasterboard, fitted furniture, kitchen units, wardrobes, sealed paint, modern plaster or previous internal finishes. A room may only start to show signs once paint bubbles, plaster breaks down, mould returns or a musty smell develops.
Older properties may also have solid walls, ageing mortar, chimney breasts, suspended timber floors, blocked airbricks or earlier repairs that affect how moisture moves through the structure.
Nordic Damp Proofing looks beyond the surface finish. We investigate where moisture is coming from, how it is travelling through the property and what needs to be corrected to stop the problem returning.
For older properties, our guide on how moisture moves through period properties may be useful. You may also find our article on damp problems in cottages helpful.
Damp and mould can become a recurring issue in rental properties when the source is not properly identified. Tenants may report condensation, black mould, damp patches, peeling paint, damaged plaster, musty smells or staining that keeps returning.
Sometimes the issue is mainly caused by humidity and poor ventilation. In other cases, there may be a building defect, leak, roof issue, failed gutter, penetrating damp, rising damp or timber moisture.
Nordic Damp Proofing works with landlords, letting agents and property managers across Hertfordshire to inspect damp and mould issues, identify the likely cause and recommend suitable remedial work.
We can help with:
For rental properties, you may find our guides on damp and mould in rental properties for landlords, damp and mould in rental properties for renters and Awaab’s Law and damp and mould useful.
Black mould is often linked to condensation, where warm moist air settles on colder surfaces. It commonly appears in bathrooms, bedrooms, kitchens, wardrobes, cupboards, window reveals, ceiling corners and behind large furniture.
In Hertfordshire homes, condensation can become worse where properties are well sealed, ventilation is limited, extractor fans are weak, rooms are not heated evenly or furniture is placed tightly against external walls.
Flats, rental homes, modern houses and busy family properties can all be affected. Everyday activities such as showering, cooking, drying clothes indoors and keeping windows closed can raise humidity quickly if moisture cannot escape.
Cleaning the mould may improve the appearance for a short time, but it will often return if humidity and airflow are not corrected.
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, why flats can get worse condensation than houses and managing condensation in the home useful.
Penetrating damp happens when water enters the building from outside. It often becomes more noticeable after heavy rain or where external walls stay wet for long periods.
In Hertfordshire properties, this may be caused by leaking gutters, blocked downpipes, cracked render, damaged pointing, porous brickwork, defective roof details, chimney issues, window surround defects, poor drainage or water collecting against external walls.
Internally, penetrating damp may appear as localised damp patches, staining, bubbling plaster, peeling paint, cold wall areas, damp chimney breasts, musty smells or water marks around ceilings and windows.
The correct repair depends on finding where water is entering. Redecorating or patch plastering will not solve the issue if the outside defect remains active.
Nordic Damp Proofing can advise on penetrating damp treatment, repointing services, wall repairs, waterproofing and associated remedial work.
Where drainage or external ground moisture may be part of the problem, our guide on whether French drains stop damp may also be useful.
