LET’S TALK ABOUT YOUR PROPERTY
Contact Black Mould On Walls
Tell us what is happening in your property. You might have a bathroom ceiling that spots over again, dampness beside a window or mould behind furniture that you have only just discovered. Call 020 4600 5413 or email office@blackmouldonwalls.co.uk. You do not need to know the cause before making an enquiry; a clear description is enough to start the conversation.

YOUR PROPERTY / THE DETAILS
Call with the rooms and postcode
The most useful starting information is your postcode, the type of property and the rooms affected. Tell us whether you own the home, rent it or are arranging the enquiry for somebody else. If the concern involves several rooms, describe the pattern across them rather than only the most visible patch. This helps us understand whether you are reporting a local treatment issue or a wider moisture problem.
You do not need exact measurements. An approximate patch size and its position are helpful: beside the window, above the shower, behind a wardrobe or beneath another room. Mention whether the surface looks wet, paint is lifting or there is a musty smell. We can discuss the appropriate service and availability without asking you to decide between technical explanations at the outset.
YOUR PROPERTY / THE DETAILS
A short history helps more than a diagnosis
Explain when you first noticed the problem and whether it changes after rain, overnight or during colder weather. Tell us what happened after previous cleaning or repainting. If a pipe, roof, fan or window has been repaired, mention when that work took place and whether the patch changed afterwards. Approximate dates are useful when exact records are not available.
It is fine to say that you do not know. A suspected leak and a confirmed plumbing repair are different pieces of information, and we want to keep that distinction clear. We do not need you to describe the problem as rising damp, condensation or a particular mould species. The observed pattern gives a better basis for discussing what should be inspected.
YOUR PROPERTY / THE DETAILS
Use email for photographs and background notes
Email office@blackmouldonwalls.co.uk if you would like to explain the problem in writing. Include your postcode, a contact number and a short description of the affected rooms. A photograph showing the whole wall or window gives useful context, while a closer image can show the surface condition. If you have photographs taken before and after a previous repair, explain their sequence.
Only send information relevant to the property enquiry. You do not need to include identity documents, private tenancy paperwork or unrelated personal records just to report a mould concern. Photographs help show location and appearance, but an image cannot measure moisture inside the wall or confirm the source of a concealed leak. We may still need to discuss an inspection before proposing work.
YOUR PROPERTY / THE DETAILS
Arrange access for an occupied home
Let us know who can meet the inspector and which areas can be reached. Bedrooms, bathrooms and the space behind furniture may need different preparation. Fixed units, concealed construction or another flat can limit what is accessible. Do not remove finishes or promise access to a neighbouring property without discussing permission and the purpose of the additional inspection first.
In a rented home, the tenant’s availability matters even if the landlord or agent is commissioning the work. Tell us who is coordinating the appointment and whether there are previous repair notes to consider. If several parties need written information afterwards, discuss that requirement before booking. Clear arrangements help avoid a visit being delayed because nobody has agreed who can provide entry or authorise further access.
YOUR PROPERTY / THE DETAILS
Ask what is included before agreeing the visit
A mould inspection, a written rental report and surface treatment are different services. Explain what you need from the appointment so the proposed scope is clear. Ask whether you are arranging an inspection only, which surfaces or rooms will be considered, and whether any further work would be discussed separately. The name of a service should not leave you guessing about the work involved.
If the concern involves active water entering the home, make that clear when seeking help. A planned moisture investigation is not the same as an urgent plumbing or building repair. Where a leak has already been stopped, tell us when it happened and what remains affected. That information helps distinguish ongoing moisture from the condition of materials and decoration after the original incident.

Contact details and the next conversation
Our published contact number is 020 4600 5413 and our email address is office@blackmouldonwalls.co.uk. The address listed for the business is 105 Sumner Street, London, SE1 9HZ. Contact the team before planning an in-person visit; a listed business address should not be taken as confirmation that there is a walk-in reception or that somebody will be available there.
During the enquiry, we can discuss your postcode, the reported problem and the appropriate starting point. Confirm appointment arrangements, access requirements and the agreed scope before making preparations. If you are not sure which service is relevant, the services overview explains the differences between treatment, condensation checks and moisture investigation. You can also call and describe the issue in your own words.
BEFORE YOU CALL
A few useful questions
Can I send photographs first?
Yes, use the published email address and include the postcode and a brief history. Photograph both the affected patch and its position in the room so there is useful context.
Can a managing agent make the enquiry?
Yes. Explain who occupies the home, who can provide access and whether a written report is required. Any inspection or treatment scope should be agreed with the appropriate parties.
