Why Replace Your Wiring?

Old, deteriorated, or improperly installed wiring is one of the leading causes of electrical failures and residential fires. Homes and commercial buildings constructed decades ago may have electrical systems that were never designed to support modern appliances, HVAC equipment, EV chargers, computers, and other high-demand devices.

A complete or partial wiring replacement can improve safety, reduce the risk of overheating, eliminate recurring electrical problems, and bring your property closer to current electrical code requirements.

You may need a professional wiring inspection or replacement if you notice:

Our electricians will inspect the existing system, identify unsafe or outdated components, and determine whether your property requires targeted repairs, partial rewiring, or a complete wiring replacement.

Frequently Asked Questions

How do I know if I need a full wiring replacement?

A full replacement may be recommended when the property has severely deteriorated wiring, widespread unsafe connections, obsolete wiring methods, inadequate grounding, or recurring electrical problems throughout the building. An inspection is necessary to determine whether complete rewiring or targeted circuit replacement is appropriate.

How long does a wiring replacement take?

The timeline depends on the size of the property, accessibility of the existing wiring, the number of circuits being replaced, permitting requirements, and whether walls or ceilings must be opened. A partial replacement may take one or several days, while a complete rewiring project may take several days or longer.

Will I need to leave my home during the work?

Not always. Some projects can be completed while the property remains occupied. However, sections of the electrical system may need to be turned off, and larger projects can create noise, dust, and limited access to certain rooms. We discuss these conditions before the project begins.

Do you pull permits for wiring replacement?

When the project requires an electrical permit, we coordinate the permit and inspection process as part of the approved scope of work. Requirements vary by city, county, and project type.

Can you replace wiring without opening the walls?

Sometimes existing access points, attics, crawl spaces, basements, and electrical boxes allow wiring to be replaced with limited wall damage. In other situations, small sections of drywall or other finishes must be opened. This can only be determined after inspecting the property.

What types of wiring do you replace?

We work with outdated, damaged, improperly installed, and undersized electrical wiring, including certain aluminum wiring systems, older ungrounded circuits, damaged copper conductors, and obsolete wiring methods such as knob-and-tube wiring.

Is wiring replacement covered by homeowners insurance?

Insurance coverage depends on the cause of the damage and the terms of the policy. Damage caused by a covered event may qualify, while replacement due solely to age, wear, or code upgrades may not. The property owner should confirm coverage directly with the insurance provider.
