A question I can answer. My hardwoods installer finished laying a beautiful Bruce floor on one of my jobs. When I showed up to put the baseboards back I discovered he threw them all away. Unbelievable!
I had to install then prime and paint in place due to time constraints and not having the room to let me prime and paint first.
I installed 188 l.f. of cove base in 4 rooms, about 16 copes and 14 mitres. Masked the p-diddly out of the floor.
Charged $1285.00 The base for all it's trouble was only .28 a foot. 1 gal of primer, and 1 gal of Velspar color, used less than a 2 qt's of either.
If I didn't have to paint I could have probably done it for around $875.
