A stitch in time saves nine.

What it means

A small repair made at the right moment saves a far bigger repair later. The image is sewing: one stitch through a tear when it first appears stops it spreading into a hole that needs nine. It is used for maintenance of every kind — houses, health, relationships and code.

Example sentences

• “Book the service now rather than after something breaks; a stitch in time saves nine.”

When it fits — and when it does not

Best said before the neglect, not after it — afterwards it lands as “I told you so”. Note the “in time” means “in good time”, not “eventually”.
