Expect more with every knob & tube wiring replacement with Aiello Home Services.

If your home was built before 1940, there's a good chance it relies on an older standardized method of electrical wiring called knob & tube, or K&T. Knob & tube can cause all sorts of headaches for homeowners, from tripped breakers and higher insurance rates to serious potential fire hazards. The CT-licensed electricians at Aiello work with Connecticut residents every year to resolve these and many other issues related to K&T. Best of all, you'll be protected throughout the project by the best service warranties and guarantees in the state.

  • High: $9,000

What factors affect the cost of knob & tube wiring?

Four major price factors tend to determine the cost of a knob & tube wiring job: the amount of rewiring required, access to the wiring, the need for a replacement electrical panel, and the contractor you hire.

  • Replacing a portion or all of a home's knob & tube: If you've noticed that one area of your home causes breakers to trip constantly, there's a chance your electrician can rewire a portion of the home's knob & tube with more modern circuitry, saving you some money with the repair. That being said, your safety is our highest priority. If we think your knob & tube poses a fire hazard, we'll share that with you, and we'll let you know what a full wiring replacement could cost.
  • Access to Knob & Tube Wiring: The accessibility of the wires can plan a major factor in the cost of a job. If the majority of the old wiring is located in the basement or attic, then it would be relatively accessible. If the wiring is primarily running through walls, this means more walls will have to be cut open, adding to the extent of the work and requiring repair after wiring has been updated.
  • The need for a new electrical panel: Older knob & tube wiring is often connected to older-style, legacy fuse boxes. This type of fuse box will need to be replaced to handle the additional amperage that's running through your new, modern circuitry. We'll always let you know if a new fuse box is necessary and guide you through the process of selecting the best one for your home.
  • The contractor you hire for the job: Pricing for knob & tube wiring projects varies from contractor to contractor. Rates are often based on an electrician's experience managing knob-and-tube, as well as their general skill level, expertise and training. An improper rewiring can cause homes to black out or even catch fire. That's why going with a company you know will do a great job is always the best choice. And with over 1,000 verified 5-star reviews, Aiello is the name you can always count on to do just that.
