Whole House Rewiring in Coos County

Q: I got quotes ranging from $3,500 to $9,000 for a panel upgrade. Why so different?

Panel upgrades vary by amperage (100A vs 200A vs 400A), whether the existing wiring needs updating, permit costs, and labor rates. Also, some contractors include meter upgrades your utility company requires; others don't. Make sure every quote covers the same scope, and always pull a permit — panel work without one is a serious fire liability.

Q: How do I know if my wiring is dangerous without tearing open my walls?

Signs include: flickering lights, burning smell from outlets, outlets that are warm or discolored, breakers that trip frequently, or outlets with only 2 prongs (ungrounded). An electrician can do a basic inspection of your panel and accessible wiring for $150–$300. Homes built before 1970 with original wiring are a higher risk category.

Q: The electrician said I need to rewire my whole house. Is this really necessary?

Full rewire is sometimes recommended when original wiring is aluminum (common 1965–1973) or knob-and-tube. But partial upgrades or specific repairs are often sufficient. Get a second opinion from a different licensed electrician before committing to a $10,000+ rewire project. Ask them to show you the specific sections causing concern.

Q: Do I need a permit for every electrical job, or just big ones?

Requirements vary by jurisdiction, but generally: any new circuit, panel work, or wiring inside walls requires a permit. Replacing an outlet or switch in-kind usually doesn't. Unpermitted electrical work is a top insurance claim denial reason and a disclosure obligation when selling. When in doubt, ask your local building department.

Q: An electrician did work but my inspector said it failed. Who pays for the fixes?

The contractor is responsible for making their work pass inspection — this is typically included in the quoted price. A reputable electrician will correct a failed inspection at no additional charge. Get this confirmed in writing before work starts. If they refuse, file a complaint with your state electrical licensing board.

Common questions

Frequently asked questions in Coos County, NH

My outlets keep tripping. Is this a DIY fix or do I need an electrician?

Tripping outlets (especially GFCI type) are often a DIY reset — find the GFCI outlet in the bathroom or kitchen and press the reset button. But if breakers are tripping, circuits are warm to the touch, or you have a fuse box older than 1980, call a licensed electrician — these are fire and shock hazards.
