Quick answers
- Suspect aluminum? Hire an electrician experienced with remediation — not a general handyman.
- Insurance questionnaires may ask about aluminum — answer from inspection, not guesswork.
- Don’t mix metals under a wire nut as a DIY fix.
- Major plumbing remodels are a chance to plan electrical upgrades in the same walls.
When to use this guide
Home inspection flagged aluminum, outlets feel warm, or you’re planning a bath remodel in an older Arlington/Fairfax home.
Why aluminum needs specialists
Oxidation and creep at connections can create heat. Proper remediation methods exist — they are electrician procedures with listed materials.
Remodel coordination
When we open a bath or kitchen for re-pipe, talk to your electrician about whether circuits in that zone should be updated while access is open. Sequencing saves drywall twice.
Failure modes to avoid
Ignoring inspection flags
Aluminum notes on a home inspection are not academic — schedule electrical evaluation.

FAQs
Can you tell if I have aluminum from a photo?
