Whether your electrical system can support a renovation or addition depends on your panel’s amperage, available breaker space, and the new loads you’re adding. Most older homes need at least a partial upgrade for a major addition — adding a 200-amp service, sub-panel, or dedicated circuits is common.
How to know
- Check service amperage (100, 150, 200, 400)
- Count free breaker slots in the panel
- List new loads (HVAC, EV charger, kitchen, hot tub)
- Run a load calculation against the service
- Identify whether a sub-panel can solve it or a service upgrade is needed
We handle the load calculation and recommend the most cost-effective path through remodel electrical, panel upgrade service, and full rewiring when needed.
