Drywall seams not even?

Hey everyone! Newbie here. Wife and I just closed on our new build 2 months ago and Iím going to start finishing the garage in a few months (paint, epoxy floor, lights). Anyway, they builder had the garage taped and mudded at the seams but Iím noticing that at some of the seams, it definitely isnít flush and the adjoining drywall itís 1/4 further out than the other sheet. Can I simply sand this all down or am I going to be stuck doing a lot of additional mudding to make it flush and even? I can post a photo in the morning for clarification as well.

Garages usually dont get the greatest quality of drywall work. Its usually easier, and less messy, to mud than sand!

Could the height difference be between a flush piece of drywall and one with a beveled edge? or is it in the framing? As noted above it's easier to add mud rather than do much sanding .... and I doubt the mud is thick enough to sand.

Assuming the seam is centered on a stud or furring strip, a 1/4 inch step is a lot unless the drywall pieces are different thickness or the stud or furring strip has an excessive twist, neither of which is easy to correct. I would opt to fill the shallow side. Use a 8 inch trowel and patching plaster for the first coat. Use a 12 inch trowel and joint compound for the second coat. If uneven, sand before painting.

Here are some photos I took this morning. Maybe itís more around 3/16Ö but I still wouldnít be able to just sand this down without destroying the drywall paper right? Trowel and mud is my best bet?

Thats probably a "ba$tard" joint. Pretty common when you have a sheet vertical, next to 2 sheets that are horizontal. You tape it just like normal. You often need to prefill the low side with a wide knife just to fill it up... then you finish just like any other butt joint.

That is just the crappy joint they put in garages and let the new guy do, it just needs some love to fix.

At least they put tape in the joint, my current "spec" house they just mudded, no tape, grand canyon seams!

Most places I've worked code required the builder to at least hang drywall and tape all the joints, further finishing and painting is optional.
