When to DIY vs When to Call a Professional

DIY projects can save money and provide satisfaction—but some tasks demand professional expertise for safety and quality. Use this framework before picking up a hammer.

1. Evaluate the Four Cs

1. Complexity – Does the job require specialized tools or calculations?

2. Code – Will local building codes or permits be involved?

3. Criticality – Could failure cause serious damage or injury?

4. Cost – Are materials cheaper if bundled with a pro's bulk order?

2. Common DIY-Friendly Tasks

- Painting interior walls

- Installing floating shelves

- Replacing faucet aerators

- Laying peel-and-stick backsplash

3. Projects Best Left to Pros

- Electrical panel upgrades – Code compliance & shock hazard

- Roof replacement – Fall risk & warranty voidance

- Load-bearing wall removal – Structural calculations required

- Gas line work – Explosion risk

4. Hybrid Approach

For mid-level tasks (e.g., hardwood flooring), consider sweat equity: do demolition and disposal yourself, then hire pros for installation.

Decision Checklist

- Do you have *at least* 25% more time than the pro's estimate?

- Will you need to buy or rent expensive tools you may never use again?

- Are you comfortable accepting liability if something goes wrong?

If you answer "no" to any, calling a professional is the prudent choice.
