ACOUSTIC CEILING · INTERIORS AND FINISHES · FIXED BY STEP 01

Attic stock is bought in month one and earned in month twelve

No one pays you for the extra cartons you buy, store for a year, and leave in a closet at closeout.

WHY IT'S AN ACOUSTIC CEILING PROBLEM

Attic stock hits ceilings harder than anyone else because tile is a dye lot product on a surface people stare at. Buying spares later gets you cartons that read slightly different from the room they're meant to patch, so the spec forces the purchase up front and the storage onto you. You're funding inventory for the owner, on your cash, with no line on the pay app that admits it exists.

WHAT IT COSTS

The size of it

On a 40,000 SF job, 3 percent attic stock is roughly 1,200 SF of tile bought and warehoused for a year with no billing event attached, plus the storage and the second purchase when the cartons get raided for punch.

Almost every ceiling spec asks for spare tile at closeout, commonly 2 to 5 percent of the installed quantity in unopened cartons. You buy it with the original order to hold the dye lot, you store it somewhere for the length of the job, and you deliver it months later. Nothing on the pay application says attic stock, because it lives inside a lump sum material number, and you don't earn it until the day you deliver it. If your own punch crew opens the cartons, or the tile gets discontinued or the shade drifts before delivery day, you buy it a second time.

WHAT TO DO

Three moves, in order

STEP 01
Break attic stock out of the material number on your bid as its own quantity and its own dollar value, in cartons.
STEP 02
Put it on the schedule of values as a stored material or closeout line so there's a billing event tied to the day you turn the cartons over.
STEP 03
Store and label it where your own punch crew can't pull from it, and get a signed delivery receipt stating the quantity when you turn it over.
