Professional mould and condensation surveys · England & Wales
Mould Surveys & Condensation Reports
Find out why mould keeps returning. DampServe provides paid, diagnosis-led mould and condensation surveys with clear written reports for homeowners, landlords, tenants, property buyers and letting agents.
We assess whether the cause is condensation, insufficient ventilation, cold surfaces, leaks, penetrating damp, rising damp or a combination of factors — before recommending suitable next steps.
Reports normally include a quotation for appropriate remedial works where needed. A report-only option without a treatment quote is available on request. There is no obligation to instruct us for repairs.
Investigate the source of damp and mould before choosing treatments or repairs.
Diagnosis firstIdentify contributing moisture sources rather than guessing from staining.

Understand the cause
Why book a mould or condensation survey?
Mould is usually a symptom. A professional inspection helps establish why moisture is collecting and what should happen next.
Root-cause diagnosis
We investigate mould growth without assuming that damp proofing, chemicals or expensive treatments are the answer.
Landlord and tenant reports
Written findings can help landlords, tenants, agents and property managers understand the likely causes and practical action.
Evidence-based advice
We consider moisture readings, ventilation, humidity, temperature where relevant, heating patterns, defects and maintenance.
Proportionate recommendations
The report explains suitable next steps and, where appropriate, includes quotations for work. A report-only option is available on request.
Condensation and moisture
Many mould problems are condensation-related
Black mould on walls, ceilings, around windows, behind furniture, in wardrobes or on clothes is commonly linked to condensation, high humidity, cold surfaces and inadequate ventilation. In many cases, a new damp proof course is not the answer.
We inspect affected areas and consider ventilation, heating, moisture levels, cold bridging, leaks, external defects and signs of penetrating or rising damp.
Find the cause first, then recommend practical, proportionate solutions.
Property reporting
Reports for homeowners, landlords and tenants
Damp and mould complaints deserve proper investigation. Our paid surveys provide written evidence and practical recommendations for homeowners, tenants, landlords, letting agents, housing providers, buyers and property professionals.
Findings may point to ventilation, heating, leaks, building defects, maintenance issues, moisture penetration or several contributing factors.
Where repairs, suitable treatments or further investigation are required, the report explains why. A quotation for suitable work is normally included unless you request a report-only service.
What we examine
What we check during a mould survey
A mould survey is more than a quick look at black staining. We assess accessible affected areas and wider moisture conditions to help explain why mould is developing.
- Moisture readings in affected and surrounding areas
- Humidity and temperature conditions where relevant
- Ventilation provision and air movement
- Cold surfaces, condensation risk and thermal bridging
- Signs of leaks, plumbing faults or roof and gutter defects
- Indicators of penetrating damp and rising damp
- Patterns of mould growth and contributing factors
- Practical, prioritised recommendations
The written report describes the findings in plain English and can help you make informed decisions about the next steps.
Not sure where to start?
Send photos first
Photos of mould, damp patches or condensation can help us advise which survey is most suitable. They do not replace an inspection where a written report is required.

Common problems
Mould and damp issues we investigate
Different problems can look alike. We assess the possible causes rather than treating every patch as rising damp.
Black mould on walls
External walls, ceilings, window reveals, corners, wardrobes and behind furniture.
Condensation problems
High humidity, inadequate air movement, cold surfaces and condensation risk.
Damp or wet walls
Leaks, penetrating damp, bridging, ground levels and other building defects.
Rented property concerns
Evidence-led reports for landlords, tenants, agents and property managers.
Clear written findings
What is a mould report?
A mould report is the written document provided following the inspection. It explains what was inspected, observations and evidence, possible causes of damp or condensation, and recommended next steps.
Depending on the property, the report may include moisture readings, photographs, ventilation observations and comments on leaks or building defects.
Where appropriate, recommendations may involve ventilation improvements, maintenance, leak repairs, mould removal or specialist remedial work. A quotation for works is normally included where necessary, unless you have requested report-only.
What can the report help with?
- Understanding recurring mould and condensation
- Making decisions before buying a property
- Responding to concerns raised by residents or property managers
- Prioritising appropriate repairs, ventilation or maintenance
- Avoiding unnecessary damp proofing
Free photo guidance or paid report?
Do I need a paid survey or free advice?
You can send photographs on WhatsApp for initial guidance about the next step. Photos alone cannot reliably establish the full cause or provide a formal written survey report.
A professional mould report requires a paid inspection of accessible areas, relevant readings and assessment of the building conditions.
DampServe provides both surveys and treatment services. Our survey fees pay for the inspection and written findings; we normally quote for necessary works, but there is no obligation to choose us for treatment. You can request a report without a remedial quotation.
If no specialist work is needed, we will explain that in the report.
How long does a survey take?
It varies with property size and the extent of the problem. A straightforward inspection may take around 30–40 minutes; more complex investigations can take longer.
How much does it cost?
Pricing depends on the property, location, access and report requirements. Contact us for a quote before booking.

Questions and answers
Mould survey FAQs
Useful information for property owners, tenants, landlords and buyers who need to understand mould and condensation.
A mould survey investigates why mould is developing. The surveyor checks accessible affected areas, moisture conditions, ventilation, condensation risk and possible building defects before providing practical recommendations.
No. Mould is frequently associated with condensation, high humidity, inadequate ventilation and cold surfaces. Rising damp is one possible source of moisture, but should not be assumed without evidence.
Yes. Our reports help landlords, tenants, letting agents and property managers understand the likely moisture causes and which actions may be appropriate. The report reflects the evidence found during our inspection.
Yes. Send photographs by WhatsApp for initial guidance about a suitable next step. Photographs do not replace a professional inspection where a written report is required.
Where the findings indicate that remedial work is appropriate, the report will normally include a quotation for suitable works. It may instead recommend ventilation improvements, repairs, maintenance, further investigation or no specialist damp proofing. You can request a report without a treatment quotation.
Cost depends on the type and location of property, affected areas, access and report requirements. We can confirm the survey fee before booking.
