how much does it cost to paint a door
If you already have a contract that didn't provide for a choice of color, then as a change order (upgrade) you don't have much leverage. However, if it's a must have, then up to $50 per door starts to sound preferable to arranging to do it later after the builder leaves. If you're talking 2, 3, or more dozen doors then what do you have to lose by making a case with the builder for settling on a flat fee, whether $500 or $1000.
