Read the spec sheet.
Then read the warranty.

The Kitchen Cabinet Manufacturers Association has certified cabinets since 1965. The standard is ANSI/KCMA A161.1, the current edition is 2022, and the certificate a maker gets names the door styles that passed and says in plain words that flat-pack cabinets are not covered. The tests run in an independent lab on samples pulled during an unannounced visit to the plant. There are more than a dozen, in five groups, and they are worth knowing because they are the failures you are trying to buy your way out of.

Structure. Every shelf and bottom is loaded at 15 pounds a square foot and left for seven days; no sag past the limit, no joint opening. A mounted wall cabinet is loaded to 600 pounds. The front joints of a base take 250 pounds pushed against the stiles from inside. A 3-pound steel ball is dropped 6 inches onto the shelves, bottoms, and drawer bottoms, the way a can gets dropped.

Drawers. Loaded at 15 pounds a square foot and run through 25,000 cycles; afterward the drawer has to work and the bottom cannot have sagged into the slide. Then a 3-pound weight is dropped 8 inches against the drawer front ten times, which is a drawer being slammed.

Doors. Swung 90 degrees, 25,000 times, with the hinges then checked for looseness. Then 65 pounds is hung on the open door, it is worked ten times, and it hangs there ten minutes. That is a child on the door.

Finish. A door goes in a box at 120 degrees and 70 percent humidity for 24 hours. Another goes through the hot box for an hour and then a cold box at 5 below zero. Then the exposed surfaces sit for 24 hours under vinegar, lemon, orange and grape juice, ketchup, coffee, olive oil, and 100-proof alcohol. Mustard gets an hour. A door edge soaks in detergent for up to a day. Nothing may discolor that will not polish off.

Of the lines Midway sells, Marsh, Kith, and Premium Choice are in the KCMA directory of certified companies. Marsh publishes its certificate: number 25099R, issued August 2025, listing 22 door styles by name. Fabuwood, U.S. Cabinet Depot, and L&C are not in the directory at this writing; their construction is on their own sheets, which the next section reads, and Midway keeps every one of them open on the floor. There is also a KCMA Severe Use standard, written first for HUD housing that turns over often; if you are building rentals, ask about it.

A cabinet warranty is one or two pages, and it is built the same way at every maker. The headline is the term. Under it are four lines that decide whether it pays: who is covered, what is paid, what is excluded, and whether it moves with the house. Here are the lines Midway sells, from their own documents.

Who. The first owner, for as long as they own the house. Marsh: "the original consumer purchaser ... for as long as they own the home in which Marsh products are originally installed." U.S. Cabinet Depot: "the original consumer purchaser ... for the lifetime of the product," proof of purchase required. Fabuwood: the "First Residential Purchaser," and for a builder, the first owner of the house. L&C: the original purchaser, as long as you own the dwelling. Not one of the four transfers to the next owner. Marsh says it "may not be transferred or assigned," U.S. Cabinet Depot and Fabuwood say "not transferable." A lifetime warranty is the life of your ownership, not the cabinet's.

What is paid. The part. Marsh: repair or replace at its election, and "does not cover any labor involved in the repair or installation of replacement parts," nor removal, nor transit damage. Fabuwood: "will not provide or pay for the cost of removal of defective product, transportation of defective, repaired or replaced product," and may refund the original price of the part instead. U.S. Cabinet Depot: repair or replace, and replacement parts "may differ from original." All three warn that a replacement door will not match the finish next to it, because the wood next to it has aged. None of them pay the installer.

What is excluded. The environment and the cleaning. Fabuwood does not cover cabinets "installed in locations that do not maintain year-round environmental controls," or hinges, slides, or cabinetwork that were modified, and it does not cover the Blum hardware at all; Blum warrants that itself, to the original homeowner, and its name has to be on the part. Marsh excludes abrasives and harsh cleaners, extreme temperature and moisture, prolonged tobacco smoke on the finish, improper installation, and cabinets bought before April 2018. L&C excludes outdoor use, improper storage before installation, and improper installation. Every one excludes the natural change of wood color in sunlight, and Fabuwood adds that finish stress lines at the joints of a painted door are the nature of the material, not a defect.

The term that is not lifetime. This is the line to find. Fabuwood's limited lifetime covers Allure, Illume, Value Premium, and Quest; its other Value series carries a limited five-year warranty. Marsh warrants wood-door cabinets for the owner's lifetime and its Captiv8 wrapped-MDF doors for five years. L&C's 2026 catalog heads the page "Limited 3 Years Warranty" and then, in the body, says the period runs as long as you own the dwelling; Midway will ask L&C which applies to your order and put the answer on the quote. When a maker sells two tiers and warrants one for five years, it is telling you where it expects the wear. That is useful information, and Lesson 3 uses it.
