Is aluminum wiring actually dangerous?

It's not automatically dangerous, but aluminum connections can loosen and overheat more than copper ones over time. Many electricians address it with proper connectors rather than full replacement in some cases.

Will my insurance company require this before renewing my policy?

Some insurers do ask for an inspection or wiring update on homes with known knob-and-tube or aluminum wiring. Check with your provider, then get an electrician's assessment.

Do I have to replace all the wiring at once?

Not always. Some homeowners do it in phases, tackling the highest-risk circuits first, though a full replacement avoids repeat labor costs down the line.

Old wiring replacement (knob-and-tube, aluminum) in Sanford, FL

Some older homes around Sanford still have wiring types that insurers and inspectors flag as a risk: knob-and-tube systems from decades past, or aluminum branch wiring installed when copper prices spiked. Both can work fine for years, but both come with known failure points (brittle insulation, loose connections at aluminum terminals) that raise fire risk over time.

This is a distinct job from a standard repair or new install. It usually starts with an inspection to map out how much of the home's wiring is affected, then a plan to replace it in stages or all at once, often opening walls or attic access to run new copper wiring.

Frequent breaker trips or warm outlets tied to old wiring runs
Renovation projects that expose old wiring behind walls
Home sale or refinance inspections requiring wiring updates

What it costs

This tends to be one of the pricier electrical jobs since it involves rewiring multiple circuits, often requiring wall or ceiling access, plus a permit and inspection. Cost scales with how much of the home is affected and how accessible the wiring is (open attic versus finished walls that need patching).
