Black mould removal should be specified from the moisture conditions, affected materials and extent of growth, not the colour alone. A service in Cyprus should explain how it assesses the cause and what its price includes. Cleaning, removal of damaged finishes, leak repair and condensation control are different tasks. A recurring patch does not prove that the whole property needs waterproofing. Before booking, ask for the observations, limits and next steps in plain language so you can compare a defined investigation with a defined repair rather than a general promise.
Ask how the moisture source will be assessed
The provider should consider condensation, plumbing, rain penetration and ground-related damp where relevant. Photographs can support planning, but a visual visit may leave concealed routes uncertain. Ask what further testing is proposed if the evidence is incomplete and how each test changes the decision. A moisture meter or thermal image is not a stand-alone diagnosis. The written findings should distinguish observations from possibilities. Claims that every mould patch is a waterproofing failure or that one coating works for all walls are reasons to ask for a more specific explanation.
Ask what will happen to the affected materials
The appropriate approach can differ between hard surfaces, porous finishes and concealed cavities. Extensive, recurrent or hidden growth warrants professional assessment before disturbance. The proposal should explain preparation, protective arrangements, removal where necessary, disposal and reinstatement. Avoid requests to sand or brush suspect material yourself to save time. A clean appearance is useful but does not describe the condition behind an unopened wall. If health concerns exist, obtain healthcare advice; neither a colour label nor a contractor's sales claim identifies the occupants' medical risk.
Ask what the price, programme and warranty actually cover
Compare like-for-like scopes, including access, source repair, remediation, drying assessment and decoration. A final repair price may not be possible until further investigation is completed. Agree how unexpected damage is recorded and authorised. Completion timing depends on the assessed work and conditions, so ask which stages are provisional. Any warranty should be written and limited to the agreed scope, with conditions and exclusions explained. It should not imply that unrelated leaks, altered occupation or uninspected areas are automatically covered. Keep the report and maintenance advice with the final offer.
Frequently asked questions
Do I need testing to name the mould species?
That depends on the purpose of the assessment and specialist advice. Colour cannot identify species, and naming it does not replace assessment of moisture and affected materials.
Should I choose the cheapest surface-cleaning price?
Compare the scopes first. Cleaning alone may be different from moisture diagnosis, source repair and remediation of damaged material. A lower price can describe a smaller task.
Is waterproofing always included in mould removal?
No. It is relevant when the supported cause requires it. Condensation or plumbing problems may call for different work.
Can a contractor promise mould will never return?
A universal promise is not a sound basis for a scope. Future conditions and unrelated defects can change. Any warranty should specify the work and its limits in writing.
Arrange the right next step
If a proposed treatment does not explain the moisture source or affected materials, ask for those omissions to be clarified. Request an assessment with the recurrence history and existing quotation so the next decision can distinguish further investigation from a properly defined removal and repair scope.
