1. Signs your home needs electrical work
Many electrical problems give warning signs before they become serious. Call a licensed electrician if you notice any of these:
- Breakers that trip often or fuses that keep blowing
- Lights that flicker or dim when appliances turn on
- An old fuse box or a panel with no room for new circuits
- Two-prong outlets, loose outlets or not enough outlets
- No GFCI protection in kitchens, bathrooms, garages or outdoors
- Plans to add an EV charger, heat pump, addition or major appliance
Safety first: a burning smell, outlets or switch plates that feel warm, buzzing, or scorch marks need attention right away. Turn off the affected circuit if you can do so safely and call an electrician.
2. Panel and service upgrades
Your electrical panel distributes power to every circuit in the house. Many older homes have 60 or 100 amp services that were never meant to handle today's loads. Upgrading to a larger service, often 200 amps, makes room for new circuits and modern equipment.
What a panel upgrade involves
- A load calculation to size the new service correctly
- An electrical permit from your town
- Coordination with your utility to disconnect and reconnect power
- Replacing the panel and, if needed, the meter socket and service conductors
- Inspection before the utility restores permanent power
The changeover itself is usually done in a day. Utility scheduling and the inspection add time, so it's best to plan ahead.
3. Rewiring and renovations
Rewiring is needed when wiring is outdated or damaged, after a fire or water damage, or when a renovation opens up walls. Doing the electrical while walls are open is the most cost-effective time to add circuits, outlets and lighting.
- Kitchens: dedicated appliance circuits, countertop GFCI outlets and under-cabinet lighting.
- Bathrooms: GFCI protection, exhaust fans and vanity lighting.
- Basements and additions: new circuits, lighting and, when needed, a subpanel.
4. Lighting, outlets and circuits
Smaller projects make a big difference in how a home works day to day: recessed lighting, ceiling fans, exterior and security lighting, extra outlets, USB outlets, dedicated circuits for appliances and home offices, and hardwired smoke and carbon monoxide alarms.
5. Home EV chargers and generators
A Level 2 charger needs a dedicated 240V circuit sized to the charger. We check your panel's capacity first. For backup power, a generator connection with a transfer switch or approved interlock lets you safely power essential circuits during an outage, without backfeeding the utility lines.
6. Permits and inspections
In New Jersey, most electrical work requires a permit from the local construction office and inspection before it is closed up or put into service. Permitted work protects your safety, your insurance and the value of your home when you sell.
Astro Group Electric pulls the permit, schedules inspections and meets the inspector, so you don't have to chase paperwork.
7. What affects the cost
| Cost driver | Why it matters |
|---|---|
| Size of the job | Number of circuits, fixtures and outlets, and the square footage involved. |
| Access | Finished walls and ceilings take more time than open framing or basements. |
| Panel capacity | If the existing service is full or undersized, an upgrade may be needed. |
| Age of the wiring | Older wiring may need to be replaced or brought up to current code. |
| Fixtures & materials | Customer-supplied or contractor-supplied fixtures and devices. |
