Back on the subject of price. I guess it depends on how you charge and wha t you charge for your time.
If you are finishing in place there will be a lot of travel time and unless you are up to speed on taping off each lite separately, the all the time t hat it takes to cut around said lites, I would be careful on my estimates. I would want to have my finish in mind, too. I have put on too much "fast dry" clear coating that didn't. You will be able to go around the jamb/tr im pretty quick, and build multiple coats.
DEPENDING ON THE FINISH CHOSEN, I could see somewhere around $1200. Dust c ontrol? Multiple coats? Floor/wall protection? Removing hardware (dead bol t, lockset, peep hole, interior chain/lever, etc.) and reinstalling it late r each time? How many coats, how many trips?
For poly/varnish/and the other similar finishes, 8 hours is dry to the touc h but will often stay sticky. Closing the door on a jamb coated at the sam e time will cause fouling of the finish sometimes after 10 hours.
I like to use the polyurethane conversion lacquers, but those are all spray ed. I don't like to hand cut in around door lites, I don't like to screw w ith hardware coming off and reinstalling, and I hate multiple trips for the same task. If you can block off enough to spray, you could get three coat s of one of the poly convertibles on in a day. I have done as many as five .
I would be more involved in trying to figure out my time based on the finis h used and job site conditions than I would the actual finishing. You got the finishing. IF the door had a lot of lites, and IF they wanted the insi de finished to match, and IF I had to fill nail holes and sand out scuffs, I could see $1200 for a PREMIUM finish. I would probably have trips to th e site to do all the prep, remove the hardware, cover the floors/concrete/p orch mateiral and apply the finish, and return later to reinstall the hardw are and pick up my drop cloths, etc. as long after product application as p ossible. Three coats? Six trips.
That being said, I spray new metal/fiberglass doors with another specialty product (commercial use fast dry) enamel on occasion with two coats of pain t and I only charge $500 and try to sell the client new hardware to bump th e price a bit. The enamel I use gets so hard (if properly applied) that yo u can't scratch it with your fingernail and it holds up great. I wish I co uld stock up on it; my Sherwin Williams rep told me they are going to quit selling the product to the public, if they haven't already. Too many VOCs.
So just as a talking point, what is your "per pass" side charge on a brushe d door with 6 - 8 panels, no windows or lites, pre-primed or already painte d? Talking minor prep, painted in place or int the client garage.
