Home Alterations Electrical Work Canterbury

Home alteration electrical work catches many Canterbury homeowners off guard. Moving walls means moving wiring, and cables buried inside framing need to be traced, rerouted, or replaced before demolition begins. Many older properties across Darfield, Banks Peninsula, and Selwyn have wiring runs through the exact walls being removed, and discovering live cables mid build creates safety hazards and costly delays.

The complexity grows with the scope. Open plan conversions require completely new lighting layouts and relocated switch positions. Second storey additions need full circuit runs from the switchboard with correct cable sizing for the extended distance. Rural Canterbury properties face additional challenges with switchboards already at capacity from heat pumps and hot water cylinders, leaving no room for extra circuits. Without an electrician involved from planning, homeowners end up with power points in wrong positions, insufficient lighting, and change orders that blow the budget.

We get involved at the planning stage, before your builder starts swinging hammers. That means mapping every existing cable run, identifying what needs rerouting, and designing the new lighting and power point layout around the altered floor plan. This approach has saved Canterbury homeowners thousands in change orders and rework across over 1,500 projects since 2008. Every alteration gets a full switchboard capacity check, and if your board needs upgrading to handle the new layout, we sort that as part of the job.
