Bought the house a year ago and whoever did the trim on our stairs did a very bad job. I've never messed with trim before so I have some questions. I have all the trim pieces, but if you breathe on them they fall off.
Do I need a nail gun? Do I need to repair the gaps before I re-secure the trim? Do I need to use some kind of screws for the bit at the top of the stairs? Is there an online resource with a walk-through for a job like this?
Thanks in advance from a clueless beginner.
