Installing a drywall ceiling at bottom of cellar stairs. I have a box for the light and one for the smoke detector to deal with. Used a scrap of drywall to get it flush but as I nailed it to the joist the side not against the joist keeps pulling downward and now extends below the ceiling. Any other tips? Driving me F’n crazy! Thanks

Flex the box upward against the nails and or slip a shim near the joist to flush the box.

What type / size box?

Could cut it out and use a Madison electric or similar box that can screw into the joist at the depth you want.

Assuming that you used a plastic box, use your vibrating palm sander and sand the box flush with the ceiling surface. Take about 2 minutes.


Your oscillating multi tool with plunge cutting blade would be faster.

i screw a small piece of wood to the outside of the box on the side that is dropping,


the wood rests on top of the drywall to support that side of the box,


mount the wood first, then put the box up there and mount it to the stud,


use self tapping screws from the INSIDE of the box to the outside to fasten the wood

For detectors and small light fixtures, a old-work round box is pretty simple.
And no issues with being flush.

Decided to just go with a couple old work boxes. Seems a whole bit easier 👍
