Old homes can present some unique challenges when it comes to electrical wiring. Many times the existing wiring is outdated, insufficient for modern needs, or downright dangerous. Rewiring a 100 year old home brings things up to modern safety standards. However, opening up walls for new wiring can be messy, disruptive, and expensive. Here are some tips on how to rewire your vintage home quietly and without a trace.
Assess The Existing Electrical System
Before doing any work, you need to understand what kind of wiring your old house currently has.
-
Knob and Tube Wiring - This early form of electrical wiring ran through the framing cavities with ceramic knobs separating the wires. It can be a fire hazard and is unsuitable for modern needs. This old wiring must be replaced.
-
Armored Cable (BX) - BX wiring has an outer metal covering and was used from the 1920s-1950s. It can be safely upgraded in many cases.
-
Romex Cable - Plastic-insulated wiring that has been used since the 1950s. If in good condition, it may not need replacement.
Consult an electrician to inspect your existing wiring and determine what needs to be changed.
Plan Your New Circuitry
Modern homes require more wiring capacity than old homes. When rewiring, it's a good idea to add more circuits to reduce strain and allow for future needs.
-
Evaluate which rooms need more outlets and lighting circuits. Add dedicated circuits for large appliances like refrigerators, laundry machines, and air conditioners.
-
Consider adding 240-volt circuits for electric ranges, dryers, or vehicle charging stations.
-
Include capacity for future needs like smart switches, outdoor lighting, and low voltage lighting.
Careful planning ensures your rewired home will meet all your electrical needs for decades to come.
Fish New Wires Through Existing Walls
When possible, use the existing wall cavities to run new wiring. This avoids opening up walls for new cable runs.
-
Use wire fishing tools like fiberglass rods to thread new wires through walls and ceilings.
-
Look for openings around vents, pipes, and chimneys to drop new cables down to outlets.
-
Consider making small holes discreetly in closets or behind furniture to access wiring paths. Patch with spackle after.
Fishing wire avoids major demolition and contains the mess to small access points.
Replace Outlets And Switches Discreetly
Upgrading the receptacles and switches also brings things up to modern standards without touching walls.
-
Replace old two prong outlets with grounded three prong outlets throughout the house.
-
Swap out old toggle switches with quieter modern decora rocker switches.
-
Add tamper resistant outlets in kitchens, bathrooms, and childrens' rooms for safety.
-
Install GFCI outlets near water sources like sinks and tubs to prevent shocks.
By just changing the outlet and switch faceplates, you update the visible parts without any drywall work.
Hide The Electrical Panel
The main electrical panel is the most visible part of your new wiring system. Luckily, you can easily disguise it.
-
Build an attractive false wall or cabinetry front to conceal the breaker box.
-
Install a decorative door over the panel recess to blend in with your home's style.
-
Use a curtain or wall hanging to cover the panel access discreetly.
-
Disguise the panel in a basement or closet behind an unassuming door.
Concealing the upgraded breaker box keeps your secret wiring project hidden from view.
With clever planning and discreet installation methods, you can bring your old home's wiring completely up to date without anyone being the wiser. The reward is a safer, more functional electrical system designed to serve your household needs for the next 100 years.
