The Short Answer

Next Phase Electric rewires homes across South King and Pierce County, from a single circuit to a whole house. Most rewires replace knob and tube from before about 1950, or two-wire circuits from the 1950s and 60s that have no ground. We run new copper wire with a ground through the walls and attic, replace the outlets, switches and boxes, and disconnect the old wire. Every rewire gets a permit and an inspection, which we pull and schedule. A partial rewire can take a day or two; a whole house takes several days to a couple of weeks, depending on its size and how easy the attic and crawlspace are to reach.

What We Rewire

Four Kinds of Rewiring Job

From one problem circuit to the whole house.

Knob and tube replacement

Wiring from before about 1950, on porcelain knobs with no ground. Some insurers will not write a policy until it is gone.

Ungrounded two-wire circuits

1950s and 60s wiring with no ground wire. A three-prong outlet on it is not grounded, whatever it looks like.

Partial rewiring

One floor, the kitchen, or the circuits an inspection flagged. A good way to spread the work and the cost over time.

Whole house rewiring

Every circuit replaced, with new boxes and devices, and often a panel upgrade at the same time while the walls are open.

Done Properly

What a Good Rewire Needs

Three things that separate a clean rewire from a messy one.

A plan for every opening

Wire is fished through the walls from the attic and crawlspace wherever possible. Where a wall has to be opened, the openings are small and agreed with you first.

A permit and an inspection

Rewiring is permit work. We pull the permit, the inspector checks the wiring before the walls close, and you keep the record for insurance and resale.

A panel that can carry it

A rewire often shows the panel is too small or worn out. We check it first, so you know before we start whether it needs replacing too.

When the house was wired tells you most of what is in the walls. The first three are the ones worth checking.
Which Option

Partial or Whole House?

Both get rid of old wiring. They differ in scope and time.

Partial rewireWhole house rewire
What it coversThe worst circuits first: often the kitchen, bathrooms or one floor.Every circuit, outlet, switch and box in the house.
TimeA day or two.Several days to a couple of weeks.
Living in the houseEasy. Power is off only on the circuits being worked on.Usually fine. Parts of the house are off during the day.
Best forA tight budget, or an inspection that found a few problems.Knob and tube throughout, a purchase, or a remodel.

Not sure what is in your walls? A safety inspection tells you which circuits need replacing, and the rewire price comes from that.

FAQ

Common Questions

Three things set the price: the size of the house, how much of it is being rewired, and how easy the attic and crawlspace make it to reach the walls. A partial rewire costs a fraction of a whole house. You get the exact price before any work starts.

In most cases nothing forces you to replace it in a house you already own. But it has no ground, its insulation gets brittle with age, and some insurers will not write a policy until it is replaced. If it is still in use, we recommend replacing it.

No. Most new wire is fished through the walls from the attic and crawlspace. A few small openings are usually needed, and we agree where they go with you before we start, including who patches them.

A partial rewire is usually a day or two. A whole house takes several days to a couple of weeks, depending on its size and access.

Usually, yes. Power is off on the circuits being worked on during the day, and we restore what we can each evening.

Yes. It is new wiring, so it gets a permit and an inspection before the walls close. We pull the permit and meet the inspector.

Not always. If it is a fuse box, a brand with known problems, or too small for the house, it is worth replacing at the same time. We check it before pricing the rewire.
