Florence has neighborhoods with real history — the streets around downtown, Oakdale, the older Country Club blocks — and historic homes in Darlington, Marion, and Mullins nearby. Those homes have character, and often wiring that's decades past its prime. If you own or are buying an older Pee Dee home, here's what to know about the wiring you may not be able to see.
The three wiring types found in older Pee Dee homes
| Type | Roughly when | Why it's a concern |
|---|---|---|
| Knob-and-tube | Pre-1950s homes | No ground wire; insulation ages and fails; hazardous when buried in attic insulation or amateur-spliced |
| Cloth-insulated wiring | ~1920s–1960s | Fabric insulation grows brittle and crumbles, exposing live conductors |
| Aluminum branch wiring | ~1965–1973 | Expands, contracts and oxidizes at connections, creating loose, overheating joints |
None of these means your house is about to burn down — plenty of older homes have functioned for decades. But all three deserve a professional eye, because the failure mode for each is heat at a connection, which is how electrical fires start.
Signs your older Florence home needs attention
- Two-prong, ungrounded outlets throughout
- A fuse box, or a panel from a brand like Federal Pacific or Zinsco
- Warm outlet or switch plates, or a faint burning smell
- Frequent breaker trips or blown fuses
- Flickering lights across the house
- Reliance on extension cords because outlets are scarce
Our guide on the signs you need to rewire goes deeper on each of these.
Aluminum wiring deserves special mention
Homes built in the late 1960s and early 1970s — a meaningful slice of certain Florence-area subdivisions — sometimes used aluminum for branch circuits. The metal itself isn't the enemy; the connections are. Aluminum expands and oxidizes differently than copper, so terminations loosen and overheat over time. The fix isn't always a full rewire — approved connectors and proper remediation at each connection can address it — but it must be done correctly.
A standard home inspection often only flags wiring concerns without diagnosing them. Before you buy an older Florence-area home, it's worth having a licensed electrician evaluate the panel and accessible wiring so you know what you're taking on — and can budget for it.
Updating without gutting the house
Rewiring doesn't have to mean tearing every wall open. We map the existing system, prioritize the genuine hazards, and often fish new wiring through existing cavities to limit damage. Sometimes the right answer is a targeted rewire of the worst circuits plus a panel upgrade; sometimes a full rewire during a renovation makes the most sense. We'll give you honest options for your specific home. Serving Florence, Darlington, Marion, Mullins and the surrounding Pee Dee. Call (843) 595-9236.

How common is old wiring in Florence homes?
Quite common in the historic neighborhoods near downtown and in the older parts of Darlington, Marion and Mullins. Knob-and-tube, cloth and aluminum wiring all show up in Pee Dee homes.
Is aluminum wiring dangerous?
The risk is at the connections, which can loosen and overheat over time. It needs approved connectors and proper remediation — not just any handyman fix. We can evaluate and correct it safely.
Should I rewire before buying an older home?
Have it assessed first. A licensed electrician can tell you whether the wiring is safe, needs targeted repairs, or needs a full rewire — so you can budget before you buy.
Can you rewire without destroying my walls?
Largely, yes — we fish new wiring through existing cavities where possible and stage the work to minimize damage and disruption. Call (843) 595-9236.
