Arabian Ranches villa, the built-in joinery and wardrobes are looking tired, repair, refinish or replace?

Good instinct not to rip it all out, on a villa this age most built-in joinery looks worse than it is. What's usually repairable or refinishable: solid carcasses with tired finishes (sand and refinish or re-spray), dropped or sticking doors (realign hinges, adjust or replace hardware), and worn edges or handles, all a fraction of replacement cost. What genuinely warrants replacing: anything where the board itself has swollen, delaminated or gone soft from long-term humidity or a leak, because you can't refinish failed substrate. The climate point matters: humidity is what swells cheap board edges, so refinished or new joinery should use moisture-tolerant materials and properly sealed edges to last. So the honest split is refinish and re-hardware the solid stuff, replace only what's structurally gone. A joinery specialist who works on an Arabian Ranches villa can tell carcass-sound from board-gone on sight. Restore what's solid, replace only what's failed.
