Wiring Installation in Finished Homes
Clean, code-compliant wiring — with expert wire fishing that preserves your home.
When your walls are already finished, adding new wiring takes more than just skill — it takes care, experience, and the right tools. At Divergent Electric, fishing wires through finished walls and ceilings is our specialty. We route new wiring with minimal disruption, leaving your space clean, and safely updated to current electrical code.
Whether you're adding a few outlets or rewiring an entire room, the pricing tiers below are designed to help you budget confidently.
⚠️ Please Note: The pricing shown here is approximate and meant to support budget planning only. Final pricing depends on your home’s layout, access conditions, panel space, and code-required safety upgrades. You’ll always receive a clear estimate before any work begins.
Basic Wiring
$300–$600
Best for: Small jobs like adding or relocating a single outlet, switch, or light fixture in the same room.
Time on site: 2–3 hours
This tier covers straightforward installations with minimal wall access — usually within the same wall cavity or open ceiling. Even small changes like moving a plug “just a few feet” often require routing up and over framing, adding complexity behind the scenes.
Examples:
▪️Add an outlet behind a wall-mounted TV
▪️Move a switch to a more convenient location
▪️Install a fan timer or bathroom GFCI plug
Standard Wiring
$700–$1,400
Time on site: 3–6 hours
Ideal for: Wiring 2–3 devices across finished rooms or levels.
These jobs require longer wire runs through walls, ceilings, or floor joists. We specialize in clean wire fishing — even in tricky spaces like vaulted ceilings, staircases, or finished basements.
Examples:
▪️Install a ceiling fan with a new wall switch
▪️Add several outlets to a finished basement
▪️Extend a circuit to another side of the room or floor
Complex Wiring
$1,500–$3,500+
Time on site: 1–2 days
Ideal for: Dedicated circuits or multiple upgrades in finished areas.
This tier covers new circuits that need to be run from the panel to a distant room — often across multiple levels or structural barriers. We’re experts in fishing long wire runs while protecting your home’s finishes.
Examples:
▪️Run a 240V line for EV charger, dryer, or range
▪️Install a dedicated kitchen circuit for new appliances
▪️Wire a garden shed or detached garage from the main panel
▪️Rewire older areas with safer copper wiring
Renovation or Addition Wiring
$3,500–$6,000+
Time on site: 3+ days
Ideal for: Full rewiring of kitchens, bathrooms, or suites in finished homes.
If you’re renovating a room or replacing old, unsafe wiring, we’ll carefully remove and replace what’s inside the walls — without destroying them. Our wire fishing tools and techniques help preserve your home while we upgrade its safety and functionality.
Examples:
▪️Rewire a kitchen with dedicated appliance circuits
▪️Upgrade aluminum or knob-and-tube wiring
▪️Add multiple new outlets, switches, and lighting
▪️Install a sub-panel and multiple circuits for a finished suite
Why Wiring in Finished Homes Costs More
Unlike new construction, we don’t have access to open framing. Wiring in a finished home requires:
▪️Fishing wire through studs, ceilings, and floors without damaging surfaces
▪️Drilling through structural framing and fire blocks with care
▪️Navigating insulation, vapour barriers, HVAC, and plumbing
▪️Working within existing circuits and panel capacity
▪️Providing patch-ready access, not demolition
It’s more time-intensive — but it ensures your home remains clean, safe, and up to code.
Why Wire Fishing Matters
Finished homes require finesse. Instead of cutting large holes or using exposed conduit, we:
▪️Fish wires behind drywall and through ceilings
▪️Work through insulation and vapour barriers
▪️Use low-impact access techniques to keep your home clean
▪️Leave you with patch-ready openings (no mess, no guesswork)
This is where we shine. It’s not just part of the job — it’s what we do best.
