Panel Upgrade vs Subpanel, and Repair vs Full Rewire

If your main panel is out of breaker spaces but the service amperage is adequate, a subpanel adds circuit capacity affordably — common when finishing a basement or wiring a garage. But if the service itself is undersized — a 60A or maxed-out 100A that cannot carry your loads — a service upgrade to 200A is the real fix; a subpanel off an overtaxed service just spreads the same shortage around. The deciding question is whether you are short on slots or short on total capacity.

A single bad outlet, a failing breaker, or one problem circuit is a targeted repair — fix it and move on. A full rewire becomes the answer when the wiring itself is the problem across the house: knob-and-tube, ungrounded two-prong circuits, deteriorated insulation, or a history of unsafe modifications. Rewiring costs far more and is disruptive, but it ends the recurring hazards and brings the home up to modern, insurable, code-compliant standards. Isolated faults call for repairs; a systemically unsafe system calls for a rewire.

These are not guesses to make from a forum post — the right call depends on your actual panel, service size, and wiring condition. A licensed electrician can tell you whether a subpanel solves your capacity problem or merely masks an undersized service, and whether your home needs spot repairs or a real rewire. The pros in our network give you that honest assessment so you spend on what your home actually needs, not on a default upsell.
