Unfinished Carpentry questions, answered by experts

You can use a nail to find ceiling joists, but it’s not as reliable as a stud finder, and you’ll end up with lots of small holes in your ceiling. If the nail hits a joist, you'll feel increased resistance. Mark the spot with a pencil. Repeat this process regularly along the ceiling, 16 or 24 inches apart, until you've mapped out the joist locations.

Any bowing in a basement wall signals an issue that needs to be addressed. However, bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches. That’s why it’s essential to call a pro as soon as you notice the bowing wall. The sooner you address the problem, the easier (and less expensive) it will be to repair.

Ensures proper sealing and alignment, preventing drafts and improving energy efficiency.

Sagging floors, large cracks in your walls, and uneven door frames are three signs that your floor joists need to be replaced. You may also notice squeaky floorboards, windows that no longer close correctly, and stairs that sag on either side. You'll need a structural engineer or floor contractor to confirm whether the floor joists are the true problem behind these issues.

Rotting wood, frame misalignment, or damaged seals often require attention.
