Do-it-yourself Home Repairs.
When something breaks in your home, whatever broke usually just has one thing wrong with it.
Your faucet might just be clogged, your toilet might have a single part in the tank disconnected, or your dryer might just have a single hose loose.
Getting a repair person into your home to fix the problem can run you $100+/hour.
Most of the time you don't need to pay that cost.
You can fix the problem yourself with the help of the internet.
Trust me, I've followed many YouTube repair videos.
