Paint or replace? The honest math on kitchen cabinets.

Most kitchens that look tired do not have a structural problem. They have a color problem. The boxes are solid, the drawers work, the layout is fine, and the whole thing is simply the wrong shade of oak for the decade you are living in.

That is the kitchen where painting wins easily. Industry figures commonly put a professional cabinet painting job at roughly a third of the cost of full replacement when the boxes are sound, and it takes days rather than weeks with no demolition, no countertop removal and no kitchen out of service for a month.

But there are kitchens where painting is the wrong call, and a painter who never says so is not doing you a favor.

When painting is clearly the right move

• The cabinet boxes are solid, with no water damage or sagging
• The doors and drawers still fit, close and align
• You are happy with the layout and the storage
• The door style is one you can live with, or one you would keep
• The problem is color, dated finish, or general wear

If that describes your kitchen, painting gives you a genuinely different room for a fraction of the money.

When we will tell you not to paint

Thermofoil that is peeling

Thermofoil doors are a thin vinyl film heat-pressed over fiberboard. Once that film starts lifting, bubbling or separating at the edges, paint does not fix it. It bridges the gap for a few months and then fails along every door edge. The honest recommendation there is usually to replace the doors and keep the boxes, which is still far cheaper than a full kitchen.

Swollen or water-damaged substrate

If the material under the finish has taken on water and swelled, especially around a dishwasher or sink, there is nothing to paint onto. Coating it is money spent on a surface that is already failing.

Particleboard boxes that are delaminating

Doors might paint beautifully. Boxes that are coming apart at the shadow lines will not, and the difference is visible every time you open a door.

A kitchen you plan to remodel anyway

If the whole room is coming out in two or three years, painting is buying time at a price that does not make sense. We would rather say so than take the job.

Why prep decides everything

Cabinets are the hardest-working painted surface in a house. They get touched constantly, they live with grease and steam, and they get knocked. A finish that survives that comes from preparation, not from the can.

Degreasing comes first. A kitchen door carries months or years of cooking oil that has settled into the finish. Soap and water do not remove it. It takes a proper degreaser, and usually two passes, with the second wipe coming off dirtier than people expect. Paint applied over that residue will not bond, no matter how good it is.

Then sanding. Enough to give the surface texture to grip, not so much that you cut through a vinyl film into raw fiberboard underneath, which then drinks primer and leaves soft patches under the finish.

Then the right primer. Slick, non-porous surfaces need a bonding primer specifically. Heavily oiled old wood may need a stain-blocking primer as well, or the oils bleed through and yellow the new finish months later.

Sprayed, not brushed

This is the difference people see without knowing why. A brushed cabinet shows brush marks and stays softer; a sprayed cabinet in a cabinet-grade coating comes out smooth, hard and even, closer to a factory finish. Sprayed cabinet-grade finishes are commonly reported to last a decade or more, while brush-applied wall paint on cabinets typically starts showing wear in a few years.

It is also why doors come off and get sprayed separately rather than being painted in place. It is more work, and it is the only way to get an even finish on both faces and all the edges.

What painting cannot change

Paint changes color and finish. It does not change your layout, add storage, fix a broken drawer box, or turn a raised-panel door into a shaker door. If what bothers you about the kitchen is how it works rather than how it looks, painting will not solve it, and it is worth being honest with yourself about that before starting.
