Knob-and-tube + aluminum branch remediation in Seattle.

Active knob-and-tube wiring in pre-1950 Seattle homes and aluminum branch wiring in 1965-1972 homes are two different remediation projects with two different price points. K&T partial remediation runs $5,500-$9,500. Aluminum CO/ALR remediation runs $1,800-$4,200. We document both for your insurance carrier and pull all required permits.

Insurance docs Included

Typical home era 1925 – 1972

What drives the price

Connection points, remediation approach, insurance, panel.

01
Connection points

Outlets, switches, junction boxes — where aluminum fails most often.
02
CO/ALR vs copper pigtailing

Most insurers accept either remediation. CO/ALR is cheaper; pigtailing is more thorough.
03
Insurance carrier requirements

Some accept remediation, others demand re-pull. We work with your carrier on docs.
04
Panel + main feed

Aluminum branch wiring is OK with proper terminations; aluminum main feed is current code.

Two different problems

K&T and aluminum branch wiringare different vintages, different fixes, different costs.

Knob-and-tube (K&T) is the wiring style of pre-1950 homes. Cloth insulation, ceramic knobs, no ground conductor. The wire itself can handle modern loads at low duty cycle but cannot be wrapped in insulation (overheats) and cannot be safely modified. Aluminum branch wiring is the 1965-1972 era replacement that turned out to have a failure mode at connection points — outlets and switches loosen over heat cycles, leading to fires.

Both are remediable. K&T partial remediation ($5,500-$9,500) replaces active runs and documents dormant ones. Aluminum CO/ALR remediation ($1,800-$4,200) replaces every outlet and switch with aluminum-rated devices. Both satisfy most insurance carriers without a full $8K-$18K re-pull.

Full re-pull to copper is needed when (a) the carrier specifically demands it, (b) the existing wiring is damaged or rodent-chewed, or (c) you're remodeling and the walls are open anyway. Same scope as a whole-home rewire.

01

Day 0Schedule.

You call. We answer. A technician is introduced by name and a two-hour window is confirmed.
02

Day 1Consult.

On-site evaluation, Manual J load calc where applicable, panel + ductwork check, install photos. Written estimate in 24 to 48 hours.
03

Day 2-4Approve.

You pick your option. We pull permits, register warranties, lock in your install date and PSE rebate paperwork.
04

Day 5-7Install.

Full walkthrough before we touch a wire. Combustion analysis if any gas equipment remains, startup, full system test.
05

AfterSatisfied.

Walkthrough at the end. Anything you flag, we fix. Final payment only after sign-off. Warranty starts now.

Equipment lines we install

Remediation approaches.

CO/ALR-rated outlets + switches

Aluminum remediation

Device spec CO/ALR-listed

Required for aluminum branch wiring. Devices are designed to maintain proper torque on aluminum conductors over heat cycles, eliminating the failure mode that makes aluminum dangerous.

Per-device cost $45–$80

Acceptance Major Washington carriers

Project time 1-2 days

AlumiConn copper pigtails

Premium aluminum fix

Connection spec UL-listed

AlumiConn connectors pigtail aluminum branch wiring to copper at every termination. Most thorough aluminum remediation short of full re-pull.

Per-termination cost $25–$45

Acceptance All carriers

Project time 2-3 days

Southwire Romex copper

Full re-pull

Branch wiring 15/20A

Full copper Romex for full re-pull projects. Standard modern wiring; eliminates K&T or aluminum entirely.

Conductors Copper

Code NEC 2023 compliant

Project time 5-14 days

Why homeowners pick us

Three operational choices that change how the install lands.

Real Manual J load calculations.

We don't quote from square footage. Every system is sized from a measured load calculation accounting for insulation, windows, orientation, and air sealing. Oversized equipment is the most common failure mode we see on competitor installs.

In-house electrical.

HVAC and electrical under one roof. No subcontractor coordination, no second permit, no surprise add-ons after the gas guy leaves. If your panel needs work, we do it with the same crew on the same week.

Final payment after walkthrough.

You sign off after we walk the install with you. Anything you flag, we fix. Your money clears only after you say it's right. That clause is in writing on every install.

Black Lotus might not currently have the marketing chops of the bigger outfits, it's worth giving them a meeting. We're glad we did. They charged us 1/2 of other bids I had gotten.

Common scenarios

Common K&T + aluminum scenarios.

Insurance found aluminum wiring at policy renewal.

CO/ALR remediation is the cheapest path that satisfies most carriers. $1,800-$4,200, 1-2 days, documentation for the carrier file.

K&T discovered during home inspection.

Partial remediation handles 80% of insurance requirements at 50% the cost of full re-pull. We confirm with your carrier first.

Major remodel, walls coming open.

Right time for full re-pull. Open walls drop the price 35-45%. We coordinate with your contractor.

Common questions before you call

Quick answers before you call.

01 /

Is aluminum branch wiring really dangerous?

Only at connection points. The wire itself is fine. The failure mode is at outlets, switches, and junction boxes where the aluminum loosens over heat cycles and can arc. CO/ALR remediation fixes this.

02 /

Can I leave K&T in the walls?

Dormant K&T (not connected to active circuits) can usually stay. Active K&T must be replaced. We map both during the inspection and quote accordingly.

03 /

Will my insurance accept partial remediation?

Most major carriers do. Pemco, USAA, State Farm, and Allstate accept partial K&T remediation and CO/ALR aluminum remediation with documentation. We confirm with your specific carrier.

04 /

How long does aluminum remediation take?

1 to 2 days for a typical 3-bedroom home. We replace every outlet, switch, and junction box termination with CO/ALR-rated devices.

05 /

Will my insurance go down after remediation?

Usually yes — 5 to 10% discount typical. We provide the documentation packet your carrier needs.

06 /

Do I need to be home during the work?

Yes for the start (sign permit, confirm scope). After that you can come and go. Power is out room-by-room as we work.
