The wiring behind the walls decides what the house can do.
Knob-and-tube has no ground. Aluminium branch wiring loosens at every connection as it heats and cools. Both are why an insurer declines a policy — and both are fixable.
Home Rewiring & Knob-and-Tube Replacement
Pre-1950s knob-and-tube and 1960s–70s aluminium branch circuits are the two wiring systems insurers most often refuse to cover. Rewiring replaces them with modern grounded copper — room by room or whole-house.
What this job typically includes
- Full assessment of existing wiring type, condition and extent
- Room-by-room or whole-house replacement with grounded copper NM cable
- New device boxes, outlets, switches and grounded three-prong receptacles
- AFCI and GFCI protection where current code requires it
- Aluminium remediation with approved connectors where a full rewire is not warranted
- Drywall cut, patch coordination, permit and inspection

Tell us what is going on
Call, or spend two minutes on the quote form. We ask what the problem is, what kind of property, and where you are — enough to pass it to the right contractors and no more.

02
We pass it to local electricians
Your request goes to independent electrical contractors who work in your area and do that type of work. A panel upgrade and a PLC fault are not the same trade, so the kind of job decides who sees it.

Contractors get in touch
Contractors who want the job contact you directly to talk it through and give you a price. Compare them, ask questions, and choose who you want — or nobody.

You decide and hire
Your agreement for the work is with the contractor you choose, not with us. Before you agree, get the quote in writing, check their licence and insurance with your state, and ask whether a permit is needed.
Rewiring — what people ask.
Do I have to rewire the whole house at once?
No. Rewiring is commonly phased — the circuits an insurer cares about first, then the rest as budget allows. What matters is that the phases are planned together so you are not opening the same walls twice.
Will you destroy my walls?
There will be cuts. A skilled rewire minimises them by fishing through existing cavities, working from attics and basements, and cutting where patching is easiest. Expect patching and paint as a separate line item, usually by a drywall contractor.
Is knob-and-tube actually dangerous?
Intact, undisturbed, and not buried in insulation, it can still be functional. The danger is what it accumulates over eighty years — brittle insulation, unsafe splices, and being covered by later insulation, which is exactly how it overheats. It also has no ground, which no modern appliance expects.
