A quality work desk is the centerpiece of any good home office. It should have enough surface space for your needs, including monitors, keyboards, notes, paper materials, etc. It should be sturdy, well-built, and hold up to daily use. You also want to make sure it’s the right height and that your chair can fit comfortably under it while also providing you with plenty of legroom.
A plumber who tightens a nut a touch too far, or one who chooses the wrong wrench or washer out of dozens of different choices, can compromise the reliability of your plumbing.
It’s the same with electrical work. Using the wrong gauge of wire or fuse, not tightening or protecting joints well enough, overloading circuits, or not bringing the right tools to the job, all compromise your safety and the safety of your home.
