Damp, Mould & Condensation Assessments

Recurring mould, damp patches or condensation are often symptoms rather than the whole problem. NSU Property Services carries out property-based assessments to investigate likely moisture sources, ventilation, heating and visible building defects, with clear written findings and practical recommendations.

Damp & Mould Problems

Finding the cause, not just the symptom.

Damp and mould can have several possible causes, and more than one issue can be present at the same property. An assessment looks at the building and how moisture is behaving before recommendations are made.

01

Black mould & condensation

Mould around windows, external walls, corners, bathrooms or bedrooms, particularly where condensation and ventilation may be contributing.

02

Damp patches & staining

Localised moisture, discolouration, bubbling paint or damaged finishes that need further investigation to establish the likely source.

03

Suspected penetrating damp

Assessment of visible signs alongside relevant external defects such as rainwater goods, pointing, seals or other potential routes for water ingress.

04

Low-level moisture

Investigation of moisture readings and visible symptoms at lower wall level, without assuming that every high reading automatically means rising damp.

05

Ventilation concerns

Consideration of extract ventilation, airflow and moisture production where persistent humidity or condensation may be contributing to the problem.

06

Landlord & tenant concerns

A clear property assessment can help landlords and agents understand the physical factors present and identify sensible next steps.

The Assessment

What I look at during the visit.

The assessment is non-destructive and evidence-led. The exact checks depend on the property and the symptoms present.

  • Visible damp, mould, staining and deterioration to finishes
  • Moisture readings in relevant areas
  • Internal temperature and relative humidity where appropriate
  • Ventilation provision and extract fans
  • Heating and condensation-related factors
  • Relevant visible internal and external building defects
  • Likely moisture pathways and patterns across affected areas
  • Photographic evidence to support the written findings where useful

A clear report you can act on.

After the visit, you receive written findings explaining what was observed, the likely contributing factors and the practical steps recommended.

The aim is not simply to label a problem as “damp”. It is to provide a sensible assessment of why the symptoms are occurring and what should happen next.

Where the evidence points to an issue outside the scope of a non-invasive assessment, the report can recommend further specialist investigation rather than pretending there is certainty where there isn't.

How It Works

Straightforward from enquiry to report.

Practical Next Steps

Assessment first. Remedial work where appropriate.

NSU Property Services also carries out selected property maintenance and minor remedial work. Where an assessment identifies a suitable job within that scope, I can discuss it separately with you.

Not every damp problem needs the same trade.

Some issues may be suitable for straightforward maintenance; others may require a roofer, plumber, drainage contractor or another specialist.

The assessment and recommendations come first, with any subsequent work considered on its own merits.

Frequently Asked Questions

Damp & mould assessment FAQs.

Is black mould always caused by condensation?

No single cause should be assumed from appearance alone. Condensation is common, but the assessment considers the location and pattern of the mould alongside ventilation, humidity and relevant building defects.

Can you tell me if I have rising damp?

I can assess the visible symptoms and moisture pattern and consider likely causes. Moisture-meter readings are used as part of the overall evidence rather than being treated as proof of rising damp on their own.

Will I receive a written report?

Yes. The assessment includes clear written findings and practical recommendations following the property visit.

Do you carry out repairs as well?

NSU Property Services can undertake selected maintenance and minor remedial work where appropriate. If the issue requires a specialist trade or further investigation, that will be recommended instead.

Who are the assessments for?

I work with landlords, letting agents, property managers and homeowners who need a clearer understanding of damp, mould or condensation problems in a domestic property.
