Deferred maintenance never saves money. It moves the bill to a worse day.
Every building has a list of things that could wait. A hairline crack, a slow drain, a window that sticks. Each of them is cheap today. Each of them is also on its way to being something else: a bulge in the brick, a stained ceiling, a sash that will not close in January.
The trouble is that deferral feels free. The line item disappears from this year's budget and nothing visibly happens. But the building keeps its own accounts. Water moves in the same direction it always has, and it does not read the budget.
So we do the opposite, on purpose. We fix things in the order a building asks. We keep a reserve so that the order never depends on the month. And we write it down, so that the next person knows what was done, when, and why.
That is the whole idea. It is not clever. It is only unfashionable.
