Explain whether water runs over the edge, drips below a joint or marks the facade. Note the rain conditions and the location from the ground. Ask for the gutter and outlet to be considered together. Cleaning and repairing are different instructions, so agree how findings and extra work will be reported. Record which sections were repaired and which remain unchanged.
Describe what happens in rain
Say whether water overflows the edge, drips at a joint or runs along the downpipe. Identify the facade and floor. Mention whether the problem appears only during heavy rain or also during ordinary showers.
Consider gutter and outlet together
Ask which gutter section, outlet and downpipe connection are assessed. A complaint at one point may need a wider view of the drainage route. Clarify the boundary between roof drainage work and any underground pipe investigation.
Separate cleaning and repair
Removing debris is not the same as repairing a leaking joint or replacing a section. Ask what the cleaning price includes and how defects found during the work are reported. Agree repairs before they are carried out.
Keep a record of local repairs
Ask which length or joint was repaired and what material was used. Keep an overview photograph with the invoice. This helps identify whether a later report concerns the same repaired detail or another part of the gutter.
Give a precise location
A description such as rear facade, second floor, beside the downpipe is more useful than simply reporting a leaking gutter. Add a photograph from the ground where possible. Do not climb up to obtain a detail photograph.
Make the assignment boundary visible
For replacement, ask about length, material, brackets, disposal and connection to retained parts. For cleaning, ask whether joints and the downpipe connection are checked. Underground work must be separately identified if needed.
