Overview

The wiring behind your walls has a lifespan, and in older homes it may be decades past its prime. Knob-and-tube, cloth-insulated, and aluminum branch wiring were never designed for today's electrical loads, and as they age they become genuine fire and shock hazards. Whole-home rewiring from System Wide Services replaces that outdated system with safe, modern wiring built to current code.

Rewiring is a major project, and we approach it with care, working section by section to minimize disruption, protecting your finishes, and cleaning up as we go.

FAQ

Whole-Home Rewiring questions

Answers to what homeowners ask most. Still unsure? Call (562) 269-4747, we're happy to help.

How do I know if my home needs rewiring?

Warning signs include knob-and-tube or aluminum wiring, two-prong ungrounded outlets, frequent tripping, flickering across rooms, and any scorching or burning smell. The surest way to know is an electrical inspection. We evaluate the actual condition of your wiring and recommend rewiring only where it genuinely improves safety.

How long does whole-home rewiring take?

It depends on the size of the home, its accessibility, and whether you are living there during the work. A full rewire can take from several days to a couple of weeks. We phase the project to keep parts of your home powered and give you a realistic schedule before we begin.

Do you have to tear open all my walls?

Not entirely. Experienced electricians use existing cavities, attics, crawlspaces, and strategic access points to run new wiring with as little wall damage as possible. Some openings are unavoidable, but we keep them targeted, and we patch access points as part of leaving your home clean and intact.

Is knob-and-tube wiring dangerous?

It can be. Knob-and-tube was safe for its era but lacks a ground, becomes brittle with age, and is often overloaded or improperly modified by later work. Many insurers are wary of it. We assess its actual condition and explain honestly whether targeted repairs or a full rewire is the right call.

Will rewiring require a permit and inspection?

Yes. Rewiring is significant electrical work that requires permits and municipal inspection in Long Beach and throughout LA and Orange County. This ensures the new system is safe and code-compliant. Our electrical technicians handle the permitting and coordinate inspections so the job is properly documented.

Can I stay in my home during the rewire?

In most cases, yes. We plan the work in phases so you keep power to essential areas as much as possible, and we communicate the schedule clearly so you know what to expect each day. For larger or more complex jobs, we will discuss the best approach with you upfront.

Should I upgrade my panel at the same time?

Often it makes sense. New wiring paired with an old, undersized panel can leave you short on capacity. If your panel is outdated or full, combining a rewire with a panel upgrade is efficient and gives your home a fully modern, safe electrical system. We will advise based on your specific setup.
