Following months of being cooped up at home, you've undoubtedly identified your home's design flaws. With return-to-work or -school dates uncertain, many of you will want to add solid, more soundproof interior doors. In the age of Zoom calls, the standard hollow-core door isn't cutting it.

To save some money and DIY it, there's at least two ways to go about it.

1. New Door

You can pick up a solid wooden slab door at the home centers for around $50. With more mass, the difference in soundproofing versus a hollow-core will be night and day. But one issue is that these slab doors are typically sold un-bored, that is, there's no holes cut for the doorknob and latch. To do it yourself, you'll need a jig and a hole saw:

2. Old Door

Alternatively, you could pick up a used solid wood door at a Habitat for Humanity outpost, for instance. This will of course be pre-bored, but one issue (that can also occur if you buy a new door) is that the door may not precisely fit your doorway, particularly if you live in an older home.

You'll need to cut the door down to size, as well as add hinges that may not fit the hinge mortises already in the door. Here's how to execute those tasks and get the door in place:
