Old Wiring Does Not Have to Stay Hidden

Partial and full home rewiring services in Butte, including knob and tube replacement in historic properties.

You find out your home has knob and tube wiring when an inspector flags it during a sale or when your insurance company asks for proof of replacement. Many older homes in Butte still have this type of wiring running through walls and attics, and while it may have worked for decades, it no longer meets current safety standards and can create problems when you try to add circuits or insulate. Arc Electric Inc provides partial and full rewiring services throughout Butte, including knob and tube replacement in homes where the wiring was installed before modern electrical codes existed.

This service involves removing outdated wiring and replacing it with modern cable that can handle current loads and support grounded outlets. We work in finished spaces by accessing wiring through attics, crawlspaces, and strategic wall openings that minimize damage to plaster or drywall. The work improves safety by eliminating overheating risks, restores insurability, and prepares your home for remodels or system upgrades.

If your home in Butte has knob and tube wiring or you are planning a remodel that requires updated electrical, contact us to review what replacement involves and what access we will need.

How We Replace Wiring Without Tearing Everything Apart

We begin by mapping out existing circuits and identifying where knob and tube wiring runs through your home. In Butte, many historic homes have wiring that loops through attic spaces, drops down interior walls, and connects to outlets or fixtures that have been modified over the years. Once we know the layout, we disconnect the old wiring at the panel, fish new cable through walls or above ceilings, and install grounded outlets and junction boxes where needed.

After the rewiring is complete, you will notice that outlets accept three-prong plugs, lights no longer flicker under load, and your insurance company accepts your home without requiring additional documentation. Circuits operate reliably, and the wiring is protected inside walls rather than exposed in open air.

This service does not include drywall repair or repainting unless arranged separately. We coordinate access with you in advance and work to keep disruption contained to specific areas. Full home rewires take several days depending on size and access, while partial rewiring can often be completed in one or two days.

We can walk through your concerns ahead of time

Homeowners in Butte often have questions about what rewiring involves, how long it takes, and what they need to prepare before we start. These are the questions that come up most often during estimates and planning calls.

How do you access wiring without damaging walls?
We fish cable through attics, basements, and crawlspaces whenever possible and use small access holes in walls only when necessary. Openings are kept minimal and located where they can be patched easily.
What if my home does not have an attic or crawlspace?
We work through interior walls by removing baseboard trim, cutting small openings near outlets, and fishing wire vertically or horizontally depending on framing. The process takes longer but still avoids large-scale demolition.
Why is knob and tube wiring a problem if it still works?
Knob and tube wiring lacks a ground wire, is often buried under insulation where it can overheat, and is not rated for modern electrical loads. Insurance companies and building inspectors flag it because it increases fire risk.
What happens to the old wiring once you remove it?
We disconnect it at the panel and remove accessible sections from attics and basements. Wiring that is embedded in walls and not connected to any circuit is typically left in place and considered inactive.
How long does a full home rewire take?
Most full rewires in Butte take three to five days depending on home size, access, and the number of circuits being replaced. Partial rewiring for specific rooms or floors takes less time.
