A fault inside the flat may belong to the building
Ceiling staining can originate above; a cold boxed section may surround a shared pipe; an entrance door can be part of the block’s fire strategy. Before instructing work, compare the lease or management guidance with the physical location. Report common-service symptoms promptly and preserve photographs. Do not cover a mark simply because the internal decoration is the leaseholder’s responsibility. Likewise, a communal stair, railing or external wall should not be altered as part of a private list without authority. Separating ownership from appearance avoids spending on a finish that fails again and protects safety-critical elements from casual adjustment.
