What's the going rate for installing 5 1/4 " crown moulding

What is it made of. Mine is plaster.

There is no ging rate for this kind of work. It is all dependent on the labor rates in your area and if you want a handyman or a real carpenter.

I would recommend getting multiple quotes from good quality carpenters that have experience in thise area. Everyone can't install crown well.
And is the crown stained wood or painted? I have found it easier to hide mistakes with painted crown with the use of caulk. It gives a much better appearance.

I know that doesn't answer your question directly, but it is a loaded question to begin with. ;-)

I charge 3.50 a ft. that is material and labor.
Keep in mind this price is for mdf crown from my supplier, not a Lowe's or other homecenter.
Most of the crown I install are around 38 cent to 50 cent a ft
