Paintwork can look flawless under one light and show every roller mark under another. Inspecting under a single, convenient light source is one of the most common reasons a defect is missed at handover and noticed weeks later.
Raking light from a low angle — a lamp held close to the wall, or late afternoon sun through a window — shows up flat imperfections that overhead lighting hides completely. A finish that passes under a ceiling pendant can fail under a side lamp within days of handover.
If a room will normally be lit by a particular lamp or fitting, that is the light we check it under before calling it finished, rather than whatever happens to be switched on during the working day.
Where a flaw only appears under raking or angled light, we treat it the same as any other defect and correct it before sign-off. A finish that only looks acceptable under flat lighting is not considered complete.
Yes, where a fitting is already installed we check under it as part of final inspection, alongside a raking light check.
Changing light angle through the day, particularly low sun, reveals surface texture that flat daylight or overhead light does not show.
Yes, and ceilings often need it more, since overhead fittings frequently create the exact raking angle that shows roller stipple.
Ask us to walk the finished rooms with a raking light before you sign off the job.
A finish is only properly checked once it has been seen under more than one kind of light.
