At the risk of getting downvoted and sounding neurotic, the title. We’re buying a century home that has updated wiring in all bathrooms, kitchen, garage and laundry room, which leaves the rest of the house with K&T. We had an electrician give us a quote during our inspection period, and he said that it should be fine to not replace, but gave us a quote to replace it all and seller agreed to credit us that quote + plaster repair. I’d like to replace it, but has anyone done this and regretted it due to covering everything in lead paint dust, potential asbestos issues, etc.? We would have this done before moving in. I’m just concerned this may open a worse can of worms, but also feel it’s necessary for safety. Thanks!
