Newer-home headroom, Old Town capacity
In a newer Sherwood subdivision, a quick load calculation usually confirms the panel has room, and we install the charger circuit. In Old Town, an early-1900s or mid-century service may be too small, and there a service upgrade sometimes comes first. A Sherwood panel upgrade runs $2,500 to $7,500; our Sherwood panel upgrade page covers it. Either way we run the math before we recommend anything, so you're not paying for capacity you don't need.
