When to Call a Pro
DIY can save you hundreds of dollars per repair. But some jobs aren't worth the risk. Mistakes can cost more than hiring a professional in the first place—or put your family in danger.
Here's how to know when to do it yourself and when to make the call.
Always Call a Pro
These jobs are not DIY territory
Main electrical panel work
Adding circuits, upgrading panels, anything inside the main breaker box. The risk of electrocution or fire is too high, and most jurisdictions require a licensed electrician.
Gas lines
Any work involving natural gas or propane. Leaks can cause explosions. This isn't DIY territory.
Structural changes
Removing walls, modifying load-bearing elements, foundation work. Get it wrong and you compromise the integrity of your home.
Main water supply
Work on the main line coming into your house. A mistake here can flood your home in minutes.
Sewer line work
Beyond basic drain clearing. Main sewer lines require equipment and expertise most homeowners don't have.
HVAC refrigerant
Handling refrigerant requires EPA certification. It's illegal to do it yourself, and the chemicals are hazardous.
Roof work
Beyond basic shingle replacement. Falls are the leading cause of DIY injuries. Leave major roof work to people with proper equipment and insurance.
Probably Call a Pro
Consider hiring out these jobs
Permits required
If your jurisdiction requires a permit, that usually means inspection is required. Inspectors often want to see licensed contractor work. Check your local requirements.
Water heater replacement
Doable DIY for some, but involves plumbing, gas or electrical, and sometimes venting. Many homeowners hire this out.
Electrical beyond outlets and switches
Adding new circuits, rewiring, fixture installation in complicated locations. The consequences of mistakes are severe.
Major plumbing
Moving pipes, adding bathrooms, repiping sections of your home. Small leaks in walls cause big damage.
Anything you're not confident about
If you're second-guessing yourself, that's a signal. A $300 service call is cheaper than a $3,000 repair of your repair.

The Decision Framework
Ask yourself these questions
1. What's the worst case if I mess up?
Flooding, fire, electrocution, or structural damage means call a pro. Cosmetic issues or minor water damage might be acceptable risk.
2. Is a permit required?
Check with your local building department. Permit work often needs professional installation and inspection.
3. Do I have the right tools?
Some jobs require specialized equipment that costs more to buy than hiring out the work.
4. Am I confident?
Not "can I figure it out" but "do I feel solid about this?" Doubt is a signal.
5. What's my time worth?
A pro might do in 2 hours what takes you a full weekend. Sometimes hiring out makes sense even when DIY is possible.
