Describe the symptom carefully

A damp patch, a cracked surface or a loose tile is an observation, not a complete diagnosis. Record where it appears, when it was first noticed and whether it changes after rain, temperature changes or building use. Photographs taken from the same position over time can help explain a pattern. Include a wider view so the relationship with roofs, openings, plumbing and ground levels is visible. Avoid drawing structural conclusions from appearance alone. If a condition suggests an immediate risk, the appropriate professional assessment takes priority over planning decorative improvements.

Understand what information is missing

Existing drawings, previous repair records and information about alterations can help the project team understand the building. However, older buildings may contain details that are not shown in the available documents. A targeted inspection or opening-up exercise may be needed before a repair method is selected. Agree what is being investigated and how the affected area will be protected afterwards. Investigation has a purpose: reducing uncertainty about the cause and the construction to be repaired. It should not become an unstructured series of openings that creates more disruption without answering the important questions.

Consider materials as a system

A repair material must be suitable for the existing construction and the conditions in which it will work. Strength is not the only property that matters. Moisture behaviour, movement and the relationship between layers can influence whether a repair remains compatible with the building. This is particularly relevant in older masonry, mixed structures and areas where previous interventions have introduced different materials. Ask the technical team to explain why a proposed solution fits the diagnosis. A product description or an attractive sample should not replace an understanding of how the repaired assembly will behave.

Separate necessary repairs from improvements

A refurbishment often combines work needed to address deterioration with optional changes to layout or appearance. Keep those purposes visible in the brief and the quotation. This helps you understand which items respond to a diagnosed problem and which can be adjusted if the budget changes. It also helps sequence the works: concealed repairs and service coordination should generally be resolved before final finishes are installed. If new information is discovered during opening up, assess its implications before continuing with work that may later need to be undone. Clear decisions can protect both the programme and the finished result.

Plan around the people using the building

Occupation changes the practical organisation of refurbishment. Access, noise, dust, temporary service interruptions and the protection of belongings all need attention. A phased approach may help, but it should be based on actual separation between work areas and occupied areas. The team should identify which routes remain available and when an area can safely return to use. For shared buildings, communication with the relevant representatives is part of the planning process. These arrangements should be discussed before the programme is agreed, rather than treated as minor details once work has started.

Turn the diagnosis into a clear construction brief

A useful enquiry contains the location, a description of the symptoms, photographs, existing reports and the intended changes. Identify the parts of the work that are already designed and the questions still under investigation. ECOSTA can assess the execution package using that information and the responsible technical team's instructions. The quotation should distinguish confirmed repairs from provisional assumptions and explain how variations will be reviewed. This gives you a more useful basis for a decision than choosing a finish first and hoping that the hidden building will suit the proposed solution.

Keep a record of what is uncovered

Where opening up reveals a concealed detail, record the location and the technical decision made before it is covered again. Photographs should be associated with the relevant room, elevation or drawing reference. A collection of unnamed images is less useful than a small organised record. This information can support the current repair and help future maintenance understand the building. It should document the work honestly, without presenting an observation as a diagnosis that the responsible professional has not confirmed.
