What we handle: Whole House Rewiring in Knightsen
Wiring wears out. Insulation turns brittle, connections loosen and systems installed for a few lamps and a radio now feed air conditioners and computers. Whole house rewiring in Knightsen replaces that aging wiring with grounded copper circuits, modern breakers and enough outlets for the way you live now.
Aluminum wiring replacement
1960s and 70s aluminum branch circuits replaced, or repaired at every connection with approved connectors.
Whole house rewiring
New circuits, grounded outlets, switches, boxes and a labeled panel throughout the home.
Partial home rewiring
Kitchens, bathrooms or the worst circuits first, when a full rewire is not in the budget this year.
Grounding and outlet upgrades
Two-prong outlets replaced with properly grounded or GFCI-protected three-prong receptacles.
Electrical rewiring during a remodel
Open walls are the cheapest time to rewire a house. We coordinate with your contractor's schedule.
Knob and tube wiring replacement
Pre-1950 wiring with no ground and aging insulation taken out of service and replaced with modern cable.
Signs a home may need rewiring
- Cloth-covered or knob-and-tube wiring in the attic or crawl space
- Frequent blown fuses or tripped breakers
- Outlets or switches that are warm, discolored or loose
- An insurer or home inspector has flagged the wiring
- Two-prong outlets and no ground wires

Whole House Rewiring cost in Knightsen
Whole house rewiring cost in Knightsen depends on the size of the home, the number of circuits, how accessible the attic and crawl space are, and whether the panel is replaced at the same time. We walk the house, count openings and give you a written quote. Many owners phase the work, starting with the kitchen, bathrooms and panel.

Whole House Rewiring questions from Knightsen customers
Should I upgrade the panel at the same time?
Often it makes sense, since new circuits need breaker space. See our electrical panel upgrade page, or start with an electrical inspection if you are unsure what the house needs.
Can I live in the house during a rewire?
Usually. We rewire in sections and restore power to the areas you need each evening. A full rewire of an average home in Knightsen takes roughly one to two weeks.
Will you have to tear out my walls?
No. Most cable is fished through the attic, crawl space and wall cavities. We cut small access holes only where there is no other route, and we tell you first.
Is knob and tube wiring dangerous?
It was safe when installed, but it has no ground, its insulation breaks down, and it was never meant to be buried in attic insulation or to carry modern loads. Many insurers also decline to cover it.
From recent customers
A 1940s house with original wiring. They rewired it room by room so we could keep living there, and labeled the new panel so clearly even I can read it.
Our old 100 amp panel tripped every time the AC and dryer ran together. Bayshore quoted the 200 amp upgrade on the spot, handled the permit and had us back on by late afternoon.
Half the house went dark at 9 pm and an outlet smelled hot. They talked me through shutting off the breaker and had someone at the door that night. He fixed a burned connection and checked the rest of the circuit.
