Electrical Wiring & Rewiring Services in Las Vegas & Henderson
From knob-and-tube replacement in older homes to full office electrical wiring for new build-outs, Penny Electric handles wiring projects of any size - done to code, the first time.
When Does a Las Vegas or Henderson Property Need Rewiring?
Homes built before the 1970s in the Las Vegas valley often still run on knob-and-tube or aluminum wiring that was never designed for today's electrical load - modern appliances, HVAC, EV chargers, and home electronics all draw more power than these systems were built to handle. Rewiring replaces outdated, damaged, or non-compliant wiring throughout a home or office with a code-current system sized for how the space is actually used today. If any of the following sound familiar, it's worth having a licensed electrician take a look before a small issue becomes a bigger one.
Signs Your Wiring Needs Professional Attention
Frequent breaker trips or flickering lights
Circuits that can't handle modern load often trip repeatedly or cause lights to dim when appliances start.
Warm outlets, switch plates, or a persistent burning smell
Heat or odor at outlets and switches signals dangerous resistance in aging or overloaded wiring.
Knob-and-tube or aluminum wiring still in the walls
Common in pre-1970s Las Vegas homes - often incompatible with modern loads, insulation, and many insurance policies.
Planning an office build-out, remodel, or major appliance/EV charger addition
New circuits and office electrical wiring require capacity and code compliance an older system may not have.
Don't Wait for a Wiring Problem to Become an Emergency

- Whole-house and partial rewiring
- Knob-and-tube and aluminum wiring replacement
- Office and commercial electrical wiring for build-outs and remodels

Electrical Rewiring FAQ
How do I know if my house needs to be rewired?
Warning signs include frequent breaker trips, flickering or dimming lights, warm outlets or switch plates, a persistent burning smell, or visible knob-and-tube or cloth-insulated wiring. If your home was built before 1970 and hasn't been rewired, it's worth a professional inspection even without obvious symptoms.
Is knob-and-tube wiring dangerous?
Knob-and-tube wiring isn't automatically unsafe if it's undamaged and unmodified, but it lacks a ground wire, isn't rated for modern electrical loads, and is often incompatible with insulation and many home insurance policies. Most insurers and most homeowners choose to replace it when identified.
How long does a full house rewire take?
A whole-house rewire typically takes several days to a couple of weeks depending on square footage, wall access, and whether drywall needs to be opened and patched. We provide a project-specific timeline as part of every quote.
Do I need a permit to rewire my house?
Yes. Electrical rewiring in Las Vegas and Henderson requires a permit and inspection. Penny Electric handles the permitting process as part of every rewiring project.
What's the difference between office electrical wiring and residential rewiring?
Office and commercial wiring typically involves higher circuit loads, dedicated circuits for equipment, and code requirements specific to commercial occupancy, while residential rewiring focuses on household circuits and safety. Penny Electric handles both.
Do you handle whole house rewire and home rewiring projects?
Yes — Penny Electric handles whole house rewire, home rewiring, and house rewiring for older Las Vegas and Henderson homes, including knob-and-tube and outdated aluminum wiring replacement. We scope partial or full projects based on what your inspection reveals.
Will rewiring make my home insurable?
In most cases, replacing knob-and-tube or outdated wiring resolves the insurance issues that block coverage on older Las Vegas homes — we document the work for your insurer and inspector.
