Start with the agreed work
Compare what you can see with the drawings, written scope, specifications and approved changes for the project. A finish can look different from an expectation without necessarily being defective; the written agreement gives everyone a clearer reference point.
Keep dated photographs and note the location and work stage. A short, specific record is more useful than a general description such as 'the finish is bad'.
Look for patterns, not one isolated detail
Repeated misalignment, inconsistent joint widths, rough transitions between finishes, or surfaces that appear uneven across a wider area may justify a closer conversation. Appearance alone does not establish the cause or whether the work meets a technical requirement.
Some work is covered by the next stage of construction. Raise visible concerns before they become difficult to inspect, and ask the builder to explain the intended finish and how it will be checked.
Agree what happens next
Describe the location, the relevant drawing or scope item, and the outcome you are asking the builder to clarify. Keep the discussion in writing and record any agreed inspection, correction or follow-up.
For structural concerns, disputes about compliance or issues that cannot be assessed visually, seek advice from an appropriately qualified independent professional. A general article cannot determine whether a particular building is safe or compliant.
For concerns about roof-mounted solar, ask whether the mounting method suits the roof and protects its waterproofing. SolarPowerGuide's guide to solar mounting systems outlines roof-mount options and factors to discuss with your installer.
Questions worth asking
Which drawing, specification or agreed finish applies here? At what stage can this work be inspected? How will the concern be assessed, and who will confirm the agreed outcome?
