A CLEAR RESPONSE TO AN OCCUPIER REPORT
Landlord Mould Services in London
Understand the property before deciding the work.
A mould complaint needs a clear account of the property problem and a workable next action. We provide inspections and discuss treatment for rental homes, with access, reporting requirements and any further repair questions agreed for the appointment.
- An occupier reporting recurring growth
- Mould found between tenancies
- An agent needing clear findings before arranging repairs

THE STARTING POINT
Understand the moisture.
Then decide the work.

Turn the complaint into an inspectable question
Begin with the occupier’s account: which rooms are affected, where growth appears, how it changes and what work has already been tried. Photographs can help plan the visit, but they are not a complete assessment of the cause. A repeat complaint warrants comparison with the earlier scope rather than an automatic instruction to clean the same area again. The Hackney repeat-complaint guide helps compare current evidence with the previous instruction.
Government damp and mould guidance emphasises addressing underlying causes and avoiding assumptions that blame tenants. In practical terms, consider accessible building conditions, ventilation and known water incidents alongside the occupier’s observations. Do not ask the resident to diagnose a concealed source before you arrange the relevant checks.

Select the current work decision
A mould inspection is appropriate when the extent or explanation needs examination before work is selected. Mould removal concerns treatment of the agreed affected areas. If a specific water route needs confirmation, a separate leak, damp or external-water investigation may be required. Booking treatment does not automatically provide all of those checks.
Tell us whether your decision concerns an occupied room, return growth after earlier works or preparation between tenancies. The appointment should be shaped around that decision. It is possible to need both investigation and treatment, but their purpose, scope and any follow-up work should remain clear to the person authorising the service.
A vacant property may permit closer access but show different heating, water use and ventilation conditions from an occupied home. Record those circumstances when deciding what the inspection can establish. Preparation before re-letting should distinguish visible condition, unresolved defects and the work needed before decoration rather than relying on a freshly painted surface. The Bermondsey pre-let guide explores those vacancy decisions.
The resident’s history and the maintenance record
Supply relevant maintenance dates, photographs and the actual description of completed work. A note saying the damp was fixed can obscure whether a pipe was repaired, a finish replaced or only a surface cleaned. Identify the component and location wherever possible, and say if part of the earlier work could not be accessed.
Ask the occupier what changed after the repair and whether the same position remains affected. Conflicting accounts do not need to be resolved before inspection; they should be recorded as different observations to check. A useful investigation considers those differences rather than selecting the account that is easiest to fit into an existing work order. In shared accommodation, Stoke Newington’s room-record guide helps keep each occupier’s observations identifiable.
Occupied-home access
Confirm the contact for entry, the affected rooms and relevant service areas. The person with the keys may not know the moisture history, so make sure the occupier’s account reaches the visit. Tell us about furniture, locked cupboards, communal spaces or another property needed to investigate the suspected route.
Any proposal to open a finish or reach a concealed component needs separate permission and practical planning. Explain who can authorise that work and how reinstatement would be arranged. If part of the property remains unavailable, findings should state that limitation. A restricted inspection should not be circulated as if every possible source has been excluded.
Share the tenant preparation page where useful so the resident can supply their own account. Their description should reach the inspection even when another person holds the keys. Confirm the appointment contact and the relevant room locations rather than assuming that a generic property file contains the present concern.
Written findings for the next work order
Written findings are available for landlords, agents and property records. Agree the appointment scope, intended recipients and the question the record needs to answer. The account should distinguish the inspected locations, observations, supported explanation and outstanding checks so the next work order addresses the actual finding. It is a record of the agreed moisture enquiry, not an instruction to repair an unconfirmed concealed defect.
Use that account to decide who needs to act next and what must be clarified before authorising work. If the finding concerns a service cupboard, identify the access holder; if it concerns a damaged finish, distinguish material work from source repair. Property findings do not settle legal liability or certify compliance with every housing requirement.
Coordinate the actual work and return check
When a source repair is needed, retain its location and completion details. Treatment, drying and reinstatement may involve further decisions depending on the materials and remaining condition. Make sure the next contractor understands what has been confirmed and what is still only a working explanation. The occupier should know what work is proposed and whom to contact if the original symptoms change.
After the work, a dated comparison at the same locations is more useful than a general statement that the room looks better. Agree any return appointment separately. Prevention advice can help establish practical follow-up actions, but it should not replace an outstanding building repair or assume the resident can control inaccessible services.
Have the postcode, property type, affected rooms and access contact ready. Add the earlier repair details and tell us whether the appointment is being arranged by the landlord, managing agent or another authorised person. A concise description of the current decision is more useful than a long list of unconfirmed diagnoses.
We discuss the appropriate inspection or treatment and how its findings will help you commission the next action. Include any previous work order and tell us whether the resident can attend. Price and availability are confirmed for the property. A concise brief avoids another visit which treats the visible area while leaving the original question unanswered.
YOUR QUESTIONS
Questions about landlord mould services
Can a managing agent arrange the appointment?
Yes. Provide the property details, access contact and current concern, and identify who authorises the work. Reporting requirements and intended recipients should be agreed for the booking.
Should I book treatment or inspection after a first complaint?
The appropriate starting point depends on how well the affected areas and moisture explanation are understood. Describe the concern and known defects so investigation and treatment are not confused.
Can you provide findings for a repair contractor?
Discuss the required format and purpose when booking. A useful handover distinguishes actual observations, supported explanations, recommended checks and any access limits.
Will a report decide a tenancy dispute?
No. Property findings within the agreed scope do not automatically establish legal responsibility or resolve a dispute. Obtain the appropriate advice separately for those questions.
What if mould returns after previous treatment?
Bring the earlier work description and occupier observations. Compare whether the same location and conditions are affected, whether a source was repaired and whether the original visit had access limitations.
Can inspection take place between tenancies?
Contact us to discuss the available access and intended decision. Vacancy can make some areas easier to reach, but the absence of ordinary room use may limit conclusions about occupied conditions.
Does treatment include repairing a building defect?
Do not assume it does. Source repair, mould treatment and replacement finishes can be separate work, and each should be agreed clearly before it is authorised.
