Brickwork around a leaking opening
Water visible inside near a window does not automatically mean the brick directly outside is the only cause. Show the full opening and explain the history.
Connect inside and outside observations
Take separate photographs of the interior mark and the exterior opening from safe access. Note weather conditions when leakage occurs and any earlier window or masonry work. Include the sill, sides and wall above the opening.

Define the next step
Ask which parts of the opening need assessment and who is responsible for each. A masonry repair should have a clear scope rather than an unsupported promise to solve every leak.
