Buffalo Rewire · Buffalo & Erie County
The insurance company forces this decision more often than a fire does.
Most of our knob and tube calls do not start with a spark. They start with an envelope from an insurance company.
A non-renewal notice. A remediation deadline. A quote that came back double what the neighbor pays. If you are holding one of those right now, this page is the mechanics of what happened and what the carrier actually wants from you.
Insurance companies price risk from claims data, and the data on century-old wiring is not kind. Knob and tube has no ground. Its cloth and rubber insulation dries and cracks with age. It was designed to shed heat in open air, so attic insulation blown over it turns a code-compliant 1925 installation into a heat trap. And nearly every system has decades of amateur splices hanging off it.
Here is the part homeowners struggle with. Whether your specific wiring is in good shape does not enter into it. The carrier is not underwriting your basement. It is underwriting a category, and the category loses money.
Three routes, and they all run through an inspection.
Non-renewals following inspections are the pattern we see most. The policy did not change. The carrier’s eyesight did.
Refusal to write is the most common outcome on new applications. The mainstream carriers simply pass.
Non-renewal is the existing-policy version. You get notice that coverage ends at the term, and you go shopping with a known defect on the record.
The surcharge is the third path. Some carriers will write a home with knob and tube, at premiums 50 to 100 percent higher, and often with a remediation deadline attached. The deadlines we see are blunt: fix it before closing, or fix it within 30 to 60 days of the policy starting.
Sit with that timeline for a second. Thirty days to arrange a five-figure electrical project, sometimes in a house you closed on last month. That squeeze is real, and it is exactly why people sign panic quotes from whoever answers first. Do not do that. The deadline is usually workable if you respond to the carrier quickly with a plan in writing.
Not a receipt. Not a text from a handyman saying it is handled. When a carrier asks for proof of remediation, in practice they want some combination of:
Two details matter here. First, dead wire abandoned inside walls is normal and accepted. Nobody expects you to excavate every conductor from the plaster. What matters is that no old wiring carries current. Second, partial work usually does not satisfy the letter. Rewiring the basement while the attic circuits stay live is not remediation to a carrier. It is a photograph waiting to happen at the next inspection.
Read the letter closely before you buy anything. Some letters demand full replacement. Some accept de-energizing specific runs. Some are really about the Federal Pacific panel and mention the wiring in passing. Quoting the wrong scope wastes your money in one direction or your coverage in the other.
One line on cost, because it drives every decision here: a Buffalo rewire typically runs $10,000 to $30,000 or more, and the national average for knob and tube replacement is around $24,300. The full breakdown is in our cost guide. And if you are wondering why your house still has this wiring at all, we cover the history in Why Buffalo Homes Still Have Knob & Tube.
The carrier does not want an argument. It wants paperwork. Get the right paperwork the first time.
