As I gather tips and tricks as I work with my friend who is a contractor, I’ll be taking those tips and posting here.
Some things I’ve already done:
1. Fix loud stairs
2. Finish a basement
3. Fix loud sinks… sometimes it’s just replacing the faucet
4. Fixing a wobbling deck (but you would need a contractor for that code-wise)
5. French Drain
6. Wiring (cable, data (ethernet or CAT5) – how to fish line through a wall.
If you have any questions please ask, I have friends in all trades to ask.
