Everything Homeowners Need to Know About Rewiring Your House

If you live in an older Seattle-area home, you may have wondered whether your wiring needs to be replaced. Flickering lights, tripped breakers, old outlets, aluminum wiring, or visible knob-and-tube can raise understandable concerns.

Rewiring is one of the most impactful improvements you can make for safety, reliability, and long-term value. We help homeowners understand when a rewire is needed, what the process looks like, and what to expect before, during, and after the job. Here are the most common questions homeowners ask about whole-home rewiring.

Do I Need to Rewire My House? How Do I Know?

You may need a rewire if:

• your home has active knob-and-tube wiring
• breakers trip frequently
• lights flicker or dim
• outlets feel warm or make buzzing sounds
• circuits overload easily
• there are signs of damaged or brittle insulation
• you’re planning a major remodel
• insurance has flagged the home due to outdated wiring

Knob-and-tube, aluminum wiring, and older ungrounded systems were not designed for today’s electrical loads. If you’re using power strips or extension cords just to make your home function, that’s also a sign your wiring can’t keep up.

What’s the Difference Between Rewiring and a Panel Upgrade?

A rewire updates the wiring throughout the home – inside walls, ceilings, and sometimes crawlspaces.
A panel upgrade increases capacity, safety, and how power is distributed.

During an assessment, we determine whether the wiring itself is outdated or if the panel lacks the capacity or safety features required for your home.

How Long Does a Rewire Take?

Most rewires take anywhere from a few days to several weeks depending on:

• the size of the home
• accessibility of walls and ceilings
• existing wiring type
• whether the home is occupied
• how much patching is required

We go over all timing expectations up front so you know what to expect when planning a rewire.

Will You Need to Open Up My Walls?

In most rewires, yes, at least in some areas, and we coordinate with homeowners and contractors for patching and restoration. Modern wiring must be run through walls and ceilings, and unsafe or outdated wiring must be removed or bypassed. We work cleanly and minimize wall openings wherever possible, but some access points are necessary to complete a safe, code-compliant installation. .

Can I Live in My Home During a Rewire?

Sometimes yes, sometimes no.

It depends on:

• the size of the project
• how much wiring needs to be replaced
• access to power in key rooms
• how long circuits will be offline

We’ll walk through your options and help you decide what’s most practical and comfortable.

How Much Does a Full Rewire Cost?

Cost varies depending on:

• home size and layout
• existing wiring type
• accessibility
• panel upgrade needs
• age and condition of the electrical system

We provide a detailed, transparent estimate so you understand the full scope before work begins.

What Happens During the Rewiring Process?

A typical rewire includes:

1. Assessment & Planning – evaluating wiring type, condition, and necessary circuits
2. Permits – pulled and managed by Exact Electric
3. Removal or bypass of outdated wiring – K&T, aluminum, or damaged circuits
4. Running new circuits – dedicated equipment circuits, lighting, outlets
5. Grounding & bonding upgrades – bringing the home up to modern safety standards
6. Panel evaluation or upgrade (if needed)
7. Inspection – city inspection for code compliance, managed by Exact Electric.
8. Final walkthrough – ensuring everything works as expected

We communicate clearly at every step so you always know what’s happening.

Is Knob-and-Tube Wiring Dangerous?

Knob-and-tube isn’t inherently dangerous when untouched, but in many older homes it has been modified, insulated over, or deteriorated with age. Insurance companies often require remediation or replacement before issuing coverage.

The biggest concerns are:

• lack of grounding
• brittle insulation
• overheating under insulation
• unsafe splices or DIY repairs
• limited capacity for modern loads

What Are the Benefits of Rewiring My Home?

A full rewire gives you:

• safer wiring throughout the home
• grounded outlets
• capacity for modern appliances
• fewer overloads and tripping breakers
• higher resale value
• peace of mind knowing hidden wiring issues are fixed

It’s one of the most meaningful ways to protect your investment and improve daily use of your home.

Will Rewiring Increase My Home’s Value?

Yes. Rewired homes are safer, more functional, and more attractive to buyers. Many buyers and inspectors flag outdated wiring as a negotiation point; having a modern system eliminates that concern entirely.

Do You Handle Permits and Inspections?

Yes. We manage all permitting and inspections, ensuring the work meets current code and city requirements. You don’t have to coordinate anything separately.
