Glens Falls has no shortage of homes with character, from Victorian porches to early twentieth-century woodwork. Some of those older homes still contain knob-and-tube wiring, an electrical system common in houses built roughly from the 1880s through the 1930s. When it’s discovered during a purchase, a renovation, or an insurance application, it often raises questions about coverage.
What Knob-and-Tube Wiring Is
The system uses individual wires run through ceramic knobs and tubes inside walls and ceilings. It has no ground wire, and it wasn’t designed for the electrical demands of modern kitchens, home offices, and entertainment systems. Over time, insulation on the wires can become brittle, and later DIY repairs or blown-in insulation around the wiring can add risk.
Why Insurers Pay Attention
Some insurers won’t write a policy on a home with active knob-and-tube wiring, while others may accept it after an inspection or with conditions. The concern isn’t the age alone, but the condition of the wiring and how the home’s electrical load has changed.
A Practical Path Forward
1. Find Out What You Have
A home inspection may flag knob-and-tube, but it can be hidden. Many homes have a mix.
2. Get a Licensed Electrician’s Evaluation
A written report on the condition and extent of the wiring gives insurers better information than a general home inspection.
3. Decide on Repairs or Replacement
Some homeowners replace the system entirely, while others update circuits in stages. Your electrician can explain options, and permits may be required.
4. Keep Your Insurer Informed
Answer application questions accurately and share updates once work is complete.
Rebuilding to Today’s Codes
After a covered fire, repairs may need to meet current electrical codes. Ordinance or law coverage can help with those added costs, so it’s worth confirming your limits.
