Question 1

How do I know if I have aluminum wiring?

Accepted Answer

Look at any cable coming into the panel — aluminum is silver-colored and stamped "AL" or "ALUMINUM" on the jacket. We can inspect and confirm at no charge.

Question 2

Is aluminum wiring illegal?

Accepted Answer

No — it's still permitted in a code-compliant installation. But existing aluminum branch circuits from the 1960s–70s often have failed connections that require remediation.

Question 3

What's the difference between COPALUM and AlumiConn?

Accepted Answer

COPALUM is a specialized crimp that requires a certified installer and a leased tool — considered the gold standard. AlumiConn is a purple wire nut with anti-oxidant paste — cheaper but requires more junction box space.

Question 4

How much does aluminum remediation cost?

Accepted Answer

AlumiConn retrofit typically runs $60–$120 per device. COPALUM runs $80–$150 per device. Full copper rewire is priced like whole-home rewiring.

Question 5

Will my insurer accept AlumiConn?

Accepted Answer

Most major insurers accept AlumiConn, COPALUM, or full replacement. A few require COPALUM specifically — we'll confirm with your carrier before starting.

Question 6

Are pigtails with standard wire nuts acceptable?

Accepted Answer

No. The CPSC and every major insurer reject standard wire nut pigtails on aluminum — they fail at the same rate as the original connections.

Question 7

Does aluminum wiring damage devices?

Accepted Answer

Yes. Standard receptacles and switches aren't rated for aluminum and cause galvanic corrosion. Every aluminum-fed device must be CO/ALR rated or pigtailed to copper.

Question 8

Can I just replace the outlets and switches?

Accepted Answer

CO/ALR devices help but don't address failing splices in junction boxes. Full remediation covers every connection, not just visible ones.

Question 9

How long does aluminum remediation take?

Accepted Answer

Most 2,000 sq ft homes are complete in 3–5 days with AlumiConn or COPALUM. Full rewire runs 2–3 weeks.

Question 10

Will you provide documentation for my insurance?

Accepted Answer

Yes — every job closes with a written report listing method, device count, photos, and installer certifications for your carrier.
