Regarding the correct way to cut the baseboard shoe (quarter round) when if butts up against and ENDS at another wall with hardwood floors. I understand that the shoe is cut at a 45 degree angle where the shoe meets and ends at a door frame. However, when it meets at a wall, and ends at the wall and does not meet more quarter round, I would think the shoe would be cut at a 90 degree angle, fitting snug against the wall. The depth of the wall is greater than the baseboard and shoe, so the baseboard and shoe do not stick out into the room. Our contractor cut these at a 45 degree and there is now a pie shaped area which seems like it will only collect dirt. Is this personal preferance or is there a standard? Thank you for your comments.
