Older Home Rewiring Services
Knob and tube wiring does not provide a third wire for grounding and is therefore considered unsafe in kitchens, bathrooms, laundry rooms and outdoors. In other areas, knob and tube wiring that is in good condition with sheathing intact, properly protected from damage, and that hasn't been subjected to extended periods of overloading which can cause it to become brittle, should not pose an increased safety risk.
Aside from the preceding concerns, the primary risk with knob and tube wiring, it seems, is its relative accessibility for amateur repairs, upgrades and maintenance. It is not uncommon to see a system with knob and tube wiring that has a history of amateur work. If a house does have knob and tube wiring it should be inspected to ensure that it is properly installed and in good condition.
If a few, but not all, of the circuits are in poor condition they can be replaced eventually without rewiring the whole house. However, if most or all of the circuits are in poor condition, it may be more economical to completely rewire the home. At All Services Electric, our professional electricians can rewire your old, unsafe knob and tube wiring and replace it with modern electrical circuits.
