Describe the coating you know about.
Share the material, the approximate age of the paint, and any product or contractor information you have. Mention whether a section has been repainted, patched, or treated differently from the rest. Photos should show the whole area as well as worn edges and specific marks. It is not necessary to identify a coating by guesswork; uncertainty is useful information for the assessment. The proposed approach should account for the finish that is present and relevant product guidance before any cleaning scope is agreed.
Keep the coating information together
An old invoice, product label photograph, or note from the painter may explain a finish better than its appearance alone. Include any known difference between the main wall and repaired areas. If you have no records, describe the uncertainty; the assessment should not depend on an invented paint type or age.
Show loose paint and existing damage.
Flaking, peeling, chalky-looking surfaces, exposed material, damaged joints, and known water-entry issues deserve attention before washing. Do not photograph only the dirt you want removed. A wide view plus close-ups can help explain the condition, although a closer inspection may still be needed. Cleaning is not a repair for a coating that is failing or a promise to restore a faded finish. Some areas may need work from a painter or another trade before cleaning is appropriate, and those boundaries should be clear in the quote.
Show both the whole area and its edges
A wide view explains where the concern sits, while close photographs of corners, joints, peeling edges, or patched sections show the condition. Include known leaks or earlier water-entry problems in the same note. Photographing only the buildup can leave out details that matter when deciding whether cleaning is appropriate.
If repainting is planned, coordinate the scope.
An appearance-focused exterior clean and preparation for a new coating can have different requirements. Tell both the painting contractor and the cleaning provider about the planned sequence and the surfaces involved. The painter should establish what preparation the coating system needs, rather than relying on the name house wash to define it. Do not assume that scraping, stripping, repairs, priming, or repainting are included in a cleaning request. A written agreement should identify the work each contractor is responsible for and any conditions that must be addressed first.
Keep cleaning and paint preparation distinct
If repainting is planned, ask the responsible painter to define the preparation needed for that work. Then identify what the cleaning provider is being asked to do within that sequence. A general house wash should not silently stand in for scraping, repairs, stripping, or other preparation that has its own scope.
