House rewiring replaces old, ungrounded or damaged wiring, such as knob and tube, cloth insulated or early aluminum branch wiring, with modern grounded cable and properly protected circuits. TotalPower Electrical Services rewires older homes in Lansdale, Montgomery County and Philadelphia, maps which old circuits are still live, works from the basement and attic where possible, and handles the permit and inspection.
Lansdale Borough’s early 1900s twins and Philadelphia’s rowhomes share the same problem: original wiring that was fine for a few lights and now feeds kitchens, window units and home offices. The wiring is often a mix of eras, with old circuits still live in the attic and newer cable spliced into them.
A good rewire starts with finding out what is actually there. We test and map each circuit, then plan the new runs around what the house allows, using open joists, closets and existing chases so the patching stays small and grouped.
Signs Your Home Needs Rewiring
These are the warning signs we see most often in older homes:
- Knob and tube or cloth insulated wiring in the attic, basement or walls
- Two prong outlets throughout the house
- Lights that flicker or dim when appliances start
- Outlets or switch plates that feel warm
- Fuses or breakers that trip often
- Insurance or a home inspection report flagging old wiring
- Aluminum branch circuit wiring from the 1960s or 1970s
- Extension cords used as permanent wiring
- Planned renovation that opens walls anyway
If you are buying an older home, a wiring check before settlement can save you from surprises after it.

Why Homeowners Trust TotalPower With a Rewire
We map before we cut. Every circuit is tested and traced first, so the plan is based on what is actually live, not on guesses.
Small, grouped wall openings. We work from basements, attics, closets and existing chases where possible and keep openings together so patching is faster and cheaper.
On multi day jobs we restore essential circuits before leaving each evening, so the house stays livable.
In twins and rowhomes with shared walls, we plan around the neighboring unit. HIC License PA197924, OSHA 30 certified technicians and full insurance on every job.

How Much Does Rewiring Cost?
Rewiring cost depends on the size of the home, plaster versus drywall, how much old wiring is still live and how open the basement and attic are. These ranges reflect recent work; your quote may land outside them.
| Job | Typical range | What moves the price |
|---|---|---|
| Partial knob and tube replacement | $3,000 to $9,000 | Number of live circuits, floor access, wall finish |
| Whole home rewire, older twin or rowhome | $11,000 to $28,000+ | Square footage, plaster vs drywall, access |
| Dedicated circuit added | $400 to $1,000 | Distance from panel, wall finish, panel space |
Many rewires are paired with a panel or service upgrade. Doing both together usually saves time and a second permit.

Rewiring and Knob and Tube Questions
Is knob and tube wiring dangerous?
It can be. Knob and tube has no ground, its insulation becomes brittle with age, and it can overheat when buried under attic insulation. Undocumented splices into newer cable are often the bigger risk.
How much does it cost to rewire a house?
A whole home rewire of an older twin or rowhome typically runs $11,000 to $28,000 or more, and partial knob and tube replacement $3,000 to $9,000. Size, wall finish and access decide the final price.
Can I get insurance with knob and tube wiring?
Some insurers decline homes with active knob and tube wiring or require replacement within a set time. Replacing it with a permitted rewire and keeping the inspection records usually resolves the issue.
How long does it take to rewire a house?
A partial rewire may take a few days. A whole house rewire in an older home often takes one to three weeks, depending on size and access.
Do I have to move out during a rewire?
Usually not. We work in stages and restore essential circuits each evening so the home stays livable.
Will rewiring damage my plaster walls?
Some openings are needed, but we work from the basement, attic, closets and existing chases where possible and keep openings small and grouped for easier patching.
Can you rewire just part of my house?
Yes. Partial rewiring of the highest risk circuits, such as kitchens, bathrooms or attic runs, is common when a full rewire is not needed yet.
Do two prong outlets mean I need to rewire?
Not always. Two prong outlets can sometimes be grounded or protected with GFCI devices. We test the circuits and recommend the safest cost effective fix.
Do I need a permit to rewire a house in Pennsylvania?
Yes. Rewiring requires a permit and inspection. We file with Lansdale Borough, your township or Philadelphia depending on your address.
Should I rewire before a renovation?
Yes, if the walls are opening anyway. Rewiring during a renovation costs less and avoids reopening finished walls later.
