Buffalo Rewire · Buffalo & Erie County
The original 1920s wiring is usually the neat part. What we find spliced onto it is the problem.
We open up a lot of pre-war Buffalo houses. The 1920s electrician’s work is usually still tidy. Soldered joints, taped clean, wire run straight between its ceramic knobs.
Then you follow the line and hit 1978. Somebody added a ceiling fan. They twisted modern cable onto ninety-year-old conductors, wrapped it in friction tape, and closed the wall.
That splice is the hazard. Not the knobs.
Knob and tube was installed from the 1880s into the 1940s. Buffalo has more of it than almost any city in the country. 64 percent of the housing in the City of Buffalo was built before 1940. The national figure is around 13.5 percent. Push the line to 1950 and you cover roughly 68 percent of the city.
The system itself is simple. Two separate conductors, hot and neutral, run on ceramic knobs and passed through ceramic tubes wherever they cross framing. There is no ground wire. The insulation is cloth and rubber. Splices were soldered and taped in open air.
For its era, it was good work. It was designed to run exposed so the conductors could shed heat into the air around them.
Hold onto that last sentence. It explains most of what follows.
Three things changed since the original electrician packed up his truck.
There is also load. A circuit sized for a few light bulbs in 1925 now runs a window air conditioner, a space heater, and a microwave. The wire never got a vote.
Remediation means finding every live knob and tube circuit and replacing it with modern grounded cable. Not covering it. Not fusing it lower. Replacing it.
The sequence is consistent. We trace each active circuit from the panel out. We fish new cable through the walls, using the basement below and the attic above. We make every new connection inside an accessible junction box. We disconnect the old wire completely and remove it wherever it can be reached.
Buffalo houses cooperate with this work better than most. Balloon framing, open basements, and walk-up attics give us paths for new cable that houses in other cities do not have. Most rooms never get opened up. We cover how that works in our guide to rewiring plaster walls without demolition.
A Foursquare in Parkside is the typical job. Blown-in insulation from an energy program in the 1980s, original knob and tube buried underneath it across the whole attic floor. The owners had lived there twelve years and had no idea. A home inspector found it in an afternoon when they went to refinance. The attic circuits came out first, the rest of the house followed, and the insulation went back down over dead wire.
This is an honest fork in the road, and the right answer depends on your house.
Partial remediation kills the knob and tube and leaves any newer circuits alone. If your kitchen was rewired in 1995 and it was done right, it stays. This is the cheaper path, and for some houses it is the correct one.
But if most of the house is still original, partial work creeps toward full-rewire money without full-rewire results. At that point you do the whole-house rewire once and stop thinking about wiring for the rest of your ownership. The math on both paths is in our cost guide.
What we will not do is disconnect three visible circuits, leave live knob and tube behind the plaster, and call it remediated. That version fails the inspection that matters, and you pay twice.
Buffalo home inspectors flag knob and tube by name on pre-war inspections. Routinely. It is one of the first things they look for, because they know the insurance consequences. If a carrier letter is what brought you here, the mechanics of that letter are covered on our insurance letter page.
What clears the flag is paper, not promises. The work gets permitted. It gets inspected. You receive a written certification from us that no active knob and tube remains in the home, backed by the electrical inspection report. That package is what the carrier, the lender, or the buyer’s attorney actually accepts.
Nobody budgets for this. It surfaces during a sale or a renewal, with a deadline attached, and the first number you hear has five figures in it. The way through is knowing exactly what is in your walls and exactly what the paper in your hand requires. Both of those are knowable this week.
Old wire is not a moral failing. It is just past its shift.
