Define the need
Describe the result you want
For a repair, note which lights, outlets, or circuits are affected, whether the issue is intermittent, and any recent changes. For an installation, record the equipment model, preferred location, and existing panel location. Photos can help the contractor understand the site, but they do not replace an on-site evaluation.
Common project types
Electrical repairs, lighting, panel upgrades, EV charging, generators, outlets, rewiring, and inspections.
Useful site details
Building age, access to the panel, finished walls, outdoor runs, and any scheduling constraints.
Make a useful first call
Ask the same questions of each company
- Do you perform this type of work at my address?
- Who will assess the project and prepare the estimate?
- What licensing and insurance apply to this work, and how can I verify them?
- Will a permit or inspection be needed, and who will arrange it?
- When could work start, and what could change the schedule?
Ask for a written scope and price before authorizing work. Our estimate guide gives you a line-by-line checklist.
Know when to pause
Leave electrical diagnosis and repairs to qualified people
Do not use a directory listing as proof of a license or technical qualification. Confirm the contractor’s credentials with the authority for the project address. The Electrical Safety Foundation International recommends qualified electrician help for home electrical safety concerns.
Permit rules depend on the address and work. For properties in the City of St. Louis, consult the City electrical permit page; other municipalities and counties have their own requirements.
If there is immediate danger
For smoke, fire, or a dangerous electrical condition, move away and call emergency services. Do not wait for a directory response.
