House Rewiring for Berowra Homes
Old cloth-insulated or ageing TPS cable doesn't fail all at once. It fails quietly, circuit by circuit, until a wall finally gets opened up.
House rewiring replaces that cable properly, tested and certified, not patched around.

Six Signs Your Home Is Asking for House Rewiring
A rewire is rarely the first thing anyone suspects. These are the signs worth taking seriously.
- Cloth-covered or rubber-insulated cable visible anywhere in the roof or subfloor
- Lights sagging noticeably whenever a big appliance kicks in
- A switchboard that's already been upgraded but still feeds old, unreplaced circuits
- Frequent nuisance trips with no single obvious cause
- Discoloured switches or power points that have never been touched
- A renovation opening up walls that haven't been rewired since the house was built
A flickering lights pattern that won't settle after other fixes, or electrical repairs that keep coming back to the same section of the house, both point toward the wiring itself rather than any one fitting.
House Rewiring: What We Actually Do
Rewiring covers a wide range, from a single problem section through to every circuit in the house.
Full rewire. Every circuit replaced, usually alongside a switchboard upgrade, so the whole house runs on wiring built to today's standard.
Partial rewire. One section, wing or level replaced where everything else has already been done or isn't yet urgent.
Cable replacement. Old cloth or rubber-insulated cable swapped for modern, properly rated wiring throughout the affected circuits.
New circuit design. Extra circuits added where a renovation or extension genuinely needs them, rather than overloading what already exists.
Testing and certification. Every new circuit proven under load before it's signed off.
What Affects the Cost of House Rewiring
No two rewires cost the same, because scope and access vary enormously. The main factors:
- Whether it's a full-house rewire or one section
- Access under the floor and through the roof space
- The number of circuits, points and light fittings involved
- Wall and ceiling type, since some construction makes cable runs far easier than others
- Whether the switchboard also needs upgrading to suit the new circuits
We inspect first and price second, so the number matches your house, not an average one.
A partial rewire on an accessible subfloor costs meaningfully less than a full rewire through solid brick with no roof access. We're upfront about which situation applies before a price goes on paper.
House Rewiring in Berowra Homes
Homes off Hillcrest Road and similar streets from the suburb's original building decades often still carry a portion of their first-fit cable, especially where later extensions never came with a rewire of the original core.
That pattern shows up as one wing of the house running noticeably older wiring than the rest, usually the original core rather than a later addition.
Renovations are exactly when this comes to light. Walls open up for a kitchen or bathroom update, and the cable behind them turns out to be decades past what a modern renovation should be built on.
We treat that discovery as an opportunity to fix it properly rather than just patch around the section being renovated.
The Rules That Apply in NSW
Rewiring is licensed electrical work under AS/NZS 3000, and every new circuit is tested before being signed off.
Notifiable work is registered with the regulator, and the compliance paperwork follows once testing wraps up. That record matters for insurance and for any future sale.
Safety switches go in as standard on rewired circuits, since a modern rewire is also the natural point to bring the whole board up to today's protection baseline.
None of this is DIY territory. Opening walls to replace live cabling without a licence is illegal in NSW and genuinely dangerous.
How it works
How We Work Through a House Rewiring Job
Inspection and Scope
We assess what's original, what's already been replaced, and how much of the house genuinely needs new cable.
Written Quote
The price is set out in full before any wall or ceiling is opened.
Cable Run and Reconnection
Circuits are run section by section, with power isolated only where work is actually happening.
Testing and Handover
No circuit gets signed off until it has carried real load in front of us.
A single-section rewire often wraps in a day or two. A full house is a bigger undertaking, and we're honest about that scale at quote stage rather than after work begins.
The Difference on a House Rewiring Job
Rewiring is invasive work, into walls and ceilings that then get closed up again, so getting it right the first time actually matters.
Circuit labelling is clear and accurate once we're done, not guesswork for whoever opens the board next.
We also flag anything else worth doing while walls are already open, without turning a rewire into an unnecessary sales conversation.
Related Work and Surrounding Areas
We rewire homes across Berowra and into Mount Colah, Asquith, Hornsby and Normanhurst.
A rewire is the natural moment to also handle switchboard upgrades, since new circuits need a board built to carry them properly.

Common questions
Common House Rewiring FAQs
Do you handle strata or apartment house rewiring in Berowra?
Rewiring here is overwhelmingly standalone houses, though the occasional unit or townhouse job arrives too, and those run through the owners corporation first.
Do you supply the materials or can I buy my own?
Cable, points and fittings are all included in the quoted price, chosen for how they perform over decades rather than what's cheapest on the shelf.
What warranty comes with house rewiring?
The labour carries our lifetime workmanship guarantee, and materials get an extra year of cover beyond whatever the manufacturer provides.
How much does house rewiring cost in Sydney?
It depends heavily on scope, whether it's the whole house or a section, and how accessible the existing cable is. We price it after seeing the job, in writing, before anything starts.
Will I get a Certificate of Compliance?
Yes. Rewiring is notifiable work, so testing and a Certificate of Compliance follow once everything's connected and proven.
Can house rewiring be done without turning off power all day?
For a partial rewire, usually yes. Power only drops on the sections being replaced, though a full rewire does need longer outages as each area is reconnected.
