A kitchen with good boxes and dated doors does not need a remodel. It needs a finish. Painting the cabinets you already own costs a fraction of replacing them and takes about a week, which is why it is the most requested interior job we do.
It is also the job we most often get called in to redo, because cabinet painting punishes shortcuts more than any other surface in the house. Your cabinet doors get touched with fingertips every day, wiped with cleaners, and steamed from the dishwasher. A finish that has not cured hard will mark, chip at the edges, and go tacky in the summer.
Degreasing comes first, and it is not optional. Years of cooking leave a film on the doors around the stove that no amount of sanding will fix, because sanding just drives it into the grain. The doors get cleaned with a degreaser, rinsed, and dried before anything else happens.
Then the hardware comes off. Hinges, pulls, and catches should be removed, not masked and painted around. Doors and drawer fronts get numbered on the back so every one goes back to the opening it came from, because cabinet doors are not interchangeable even when they look identical.
After a scuff sand, the surface gets a bonding primer, then a cabinet-grade enamel, sprayed rather than brushed. Spraying horizontal doors is what produces the flat, even surface people associate with factory cabinets. Brush marks on a cabinet door are visible from across the room in raking light.
The last part is patience. Enamels reach handling hardness in a day or two but take considerably longer to fully cure. We reinstall when the finish can take it, adjust the hinges so everything closes square, and tell you honestly how long to be gentle with the doors. A kitchen done this way looks new and stays that way.
