A credible renovation company should begin with a written diagnostic, not a finish board. Walk the apartment room by room and record moisture staining, hollow plaster, cracked corners around openings, floor level changes, previous chase routes, bathroom odours, weak water pressure, and any signs that services were altered without proper documentation.
Photograph hold points while finishes are still absent: behind kitchen units, under bathroom floors, at balcony thresholds, around AC sleeves, and at the electrical board. Older apartments often need selective demolition before a reliable quotation can be issued, because the visible finish layer hides the real scope.
Ask for findings in plain language with priorities labelled as urgent, recommended, or monitor. That structure helps owners decide whether the brief is a light refresh, a corrective home renovation, or a deeper rebuild of wet rooms and services before any apartment finishing package is priced.
