My Story

Independent Damp & Mould Surveyor in Devon

I provide independent damp surveys, mould inspections and building condition reports across Devon and the South West, working with homeowners, landlords, businesses and housing providers.

My service is focused on accurate diagnosis of damp and mould problems, helping clients understand the true cause before committing to any remedial work.

Experience Across Domestic & Commercial Buildings

I have spent my career working in property surveying, renewable energy and social housing, inspecting and managing thousands of properties of all types, including:
 

  • Private homes and rental properties

  • Landlord and letting agent portfolios

  • Housing Association stock

  • MOD office buildings

  • Large dental practices

  • Schools and commercial premises
     

This broad experience allows me to assess damp, mould and building defects in both residential and commercial environments.
 

I also provide independent damp and building reports for mortgage and lending purposes, helping buyers and lenders identify risks before purchase.

Independent Damp Surveys – A Different Approach

Unlike many companies offering “free damp surveys”, I do not sell remedial treatments.

My role is to provide independent, evidence-based damp and mould surveys so you can make the right decision first time.

I take a whole-building approach, considering:

  • Ventilation and condensation risk

  • Building construction and defects

  • Heating patterns and insulation

  • Moisture movement and bridging
     

This ensures the root cause is identified, not just the symptoms.

Affordable & Proportionate Surveys

I aim to provide affordable damp surveys in Devon, with a clear and proportionate scope.

You only pay for the level of investigation that is genuinely required — no unnecessary work, no inflated recommendations.

I carry out damp and mould surveys across:

  • Exeter
