House Rewiring for Normanhurst Homes
Old wiring doesn't announce itself until it fails, and by then it's usually been quietly degrading for years behind the walls.
Our Normanhurst team rewires homes properly, staged to keep the place livable, priced in writing first. Call (02) 9538 7444 to talk through your home.
Signs You Need House Rewiring
A rewire isn't usually the first thing people consider, but these signs point straight at it.
- The house still runs on old fabric-insulated or VIR cabling from decades ago
- Multiple circuits trip or fault in ways that don't trace back to one clear cause
- Powering modern appliances means constant reliance on power boards and extension leads
- A renovation has opened up walls and revealed cabling nobody expected
- Insurance or a pre-purchase inspection has flagged the home's wiring as a concern
- Lights dim across the house when anything with real draw switches on
Cabling this old isn't just inconvenient. It's a real fire risk that gets worse, not better, the longer it's left.
What Our House Rewiring Covers
A rewire is a bigger undertaking than most electrical work, and staging it properly matters.
Full rewires: pulling out the original cabling entirely and running the whole home fresh, to current standard.
Partial rewires: rewiring specific rooms or circuits, often triggered by a renovation.
Switchboard coordination: pairing the rewire with a new board sized for the upgraded circuits.
Staged works: splitting a full rewire into phases so the home stays livable throughout.
Heritage-sensitive rewiring: working through original plaster and cornices without unnecessary damage.
Post-rewire testing: full circuit testing and certification once the new cabling is in.
We use quality cabling and switchgear throughout, not the cheapest option that happens to meet minimum standard.
What Your House Rewiring Quote Depends On
Rewiring costs vary more than almost any other job we do, and for good reason.
- The size of the house and number of circuits involved
- Full rewire versus a partial job limited to specific rooms
- Wall and ceiling access, especially through original plaster
- Whether the switchboard needs upgrading alongside the rewire
- Any asbestos or other hazard requiring special handling near the work

The Normanhurst Angle on House Rewiring
A lot of what's original in Normanhurst's Federation and inter-war stock has already outlived the lifespan it was built for.
Many still carry original fabric or rubber-insulated cable, insulation that degrades and cracks with age in ways that aren't visible from outside a wall.
Renovations on these blocks are often what finally exposes it. Opening a wall for an extension reveals cable nobody planned to touch, and rewiring that section while it's exposed is far more sensible than patching around it.
We stage larger rewires room by room where we can, so a family isn't forced out of a long-held home for weeks at a time.
Blocks near Berowra Valley National Park add a further wrinkle. Bush-edge properties see more moisture find its way into wall cavities over the decades, and that accelerates the exact insulation breakdown a rewire is meant to fix.
Standards and Paperwork, Explained Simply
House rewiring is notifiable work under the AS/NZS 3000 Wiring Rules, without exception.
Once testing confirms every circuit meets standard, a Certificate of Compliance gets lodged and handed to you.
Older homes sometimes carry other hazards alongside ageing cable, asbestos among them, and any of that gets identified and handled properly before rewiring proceeds. Attempting this work without a licence is illegal in NSW and puts the whole house at risk, not just one circuit.
How it works
Our House Rewiring Process, Start to Finish
We Assess the Whole House
A full inspection identifies what's original, what's already been touched, and what a rewire actually needs to cover.
You Get a Staged Plan and Quote
The rewire gets broken into practical stages with a fixed price for the full scope.
We Work Room by Room
Each stage is completed, tested and tidied before we move to the next, keeping disruption contained.
We Certify the Finished Home
Full testing across every new circuit, with compliance paperwork covering the whole job.
A single room's rewire might take a day or two. A full-house rewire runs across multiple visits, and we map that timeline out clearly before the first wall opens.
What You Get When We Do Your House Rewiring
Rewiring is the job where cutting corners does the most damage, so it's the one we're least willing to rush.
Every stage gets tested before we move on, rather than leaving verification until the very end of a multi-week project.
We also plan around a family actually living in the house, not just around the fastest way to finish the job.
That means keeping at least one bathroom and one working kitchen circuit live wherever the staging allows it, rather than cutting all power to a section the moment we start.
Servicing Normanhurst and the Suburbs Around It
A rewire is often paired with a fresh switchboard upgrade to handle the new circuits properly, or new power points added while walls are already open.
Wahroonga and Hornsby see just as many of our rewiring jobs as Normanhurst does.

Common questions
Common House Rewiring FAQs
What people usually ask before committing to a rewire.
How do I prepare for the job?
Clear access to the rooms and roof space involved, and let us know about anything valuable near the work area. We'll talk you through the rest.
Is a permit or notification needed for house rewiring in NSW?
Yes, a rewire is notifiable work. A Certificate of Compliance gets lodged once testing confirms everything meets standard.
What warranty comes with house rewiring?
Our labour is guaranteed for life, and the materials carry 12 months on top of the manufacturer's warranty.
Do I need a licensed electrician for house rewiring?
Always. A rewire touches every circuit in the house, and unlicensed work here is both illegal and genuinely dangerous.
Do you supply the materials or can I buy my own?
We supply all cabling and materials as standard, always to current standard. This isn't a job where bringing your own parts makes sense.
Can you do house rewiring in older homes?
It's most of what we do. Older homes with original wiring are exactly who this service is built for.
