Know your shutoffs
- Water: the main valve, and the small valves under sinks and toilets.
- Electric: the main breaker and each labeled circuit.
- Gas: the shutoff at the meter and at each appliance.
Often DIY-friendly and often not

Rules differ by location. When in doubt, call your local building department.
Permits and inspections
Plumbing and electrical changes often need a permit and an inspection, because errors can be hidden and dangerous. Ask who pulls the permit and whether the price includes it.
Warning signs
- Flickering lights, warm outlets or breakers that trip often.
- Slow drains in more than one fixture.
- Water stains, damp spots or a musty smell.
These are reasons to ask a licensed professional to take a look.
Questions worth asking
- Are you licensed and insured in my area? Can I verify it?
- Who gets the permit and schedules the inspection?
- What is the warranty on the work and on parts?
