The Decision Framework
Every home repair falls somewhere on a spectrum from "anyone can do this" to "you need a licensed professional." The key factors are safety risk, permit requirements, tool investment, your skill level, and the cost of failure.
Always DIY
- Painting — the single best ROI home project for a beginner. Low risk, cheap to fix mistakes.
- Caulking — bathtub, shower, windows. A $5 tube of caulk and a YouTube video.
- Replacing hardware — door handles, cabinet pulls, light fixtures (with power off).
- Patching drywall — small to medium holes. Kits cost $10-15.
- Replacing toilet parts — flapper, fill valve, wax ring. All easy swaps.

Always Hire a Pro
- Anything structural — load-bearing walls, foundation, roof framing
- Electrical panel work — sub-panels, main service, 240V circuits
- Gas lines — gas leaks can be fatal. Never DIY gas work.
- Major plumbing — sewer lines, water main, re-piping
- Roofing — dangerous height work with waterproofing consequences
- Anything requiring a permit — unpermitted work creates liability and affects resale
The cost of a botched DIY job often exceeds the cost of hiring a pro in the first place. A $200 plumbing repair becomes $2,000 in water damage. A bad electrical connection becomes a fire risk. Know your limits and be honest about them.
