1Five questions to ask yourself
- Do I have the tools, space and time to finish this?
- What is the worst thing that could go wrong, and could someone get hurt?
- Does my area require a license or permit for this work?
- Will it be hidden behind walls once done?
- Would a mistake affect insurance, resale or warranties?
2A rough sorting guide
| Often suited to DIY | Often needs a professional |
|---|---|
| Painting and patching | Electrical panel and wiring changes |
| Caulking and weatherstripping | Gas lines and appliances |
| Swapping cabinet hardware | Structural changes, load-bearing walls |
| Simple shelving | Roofing at height |
This is a general guide only. Rules vary by location and by what you already know how to do.
3The hidden costs of each path
DIY costs time, tools and the chance of redoing work. Hiring costs money up front but may include warranties and insurance. Neither is automatically cheaper.
4Mixing both
Many people do prep, paint or demolition themselves and hire out the technical parts. If you do this, agree in writing about who does what, and who is responsible for the schedule.
5Where to check
Your local building department can tell you what needs a permit. Your state licensing board can confirm a license. Neither is a recommendation of any business.
