Northumberland Real Estate Spark !

Once you find a home or real estate in Northumberland we’ll schedule an inspection.  The  Northumberland Home Values Group will recommend an inspector to you.    At the property – you’ll follow the home inspector around asking questions about various components in the home.  When the inspector uncovers knob and tube wiring. You have heard about this kind of wiring in older homes from the 1920s right up into the 1970’s in some parts of Northumberalnd, but what does that mean to you as a home buyer:

Will I be able to get home insurance?

Is it safe?

Should it be replaced?

The home inspector may suggest that you have the wiring inspected by a qualified Cobourg or Port Hope electrical contractor to see if the wiring is functional.     Or  should it be replaced or repaired and at what cost. In some cases you will not be able to insure a home with knob and tube wiring.

He can check for:

  • Improperly abandoned knob and tube electrical wiring.
  • Circuits that have been extended to include new circuits and devices.
  • Damaged wire and wire insulation
  • Knob and tube wire that has been insulated-over or around, creating a fire risk.
  • and other damage or defects that make the wiring system unsafe.

Knowing What You’re Buying Is Critical

What if he discovers aluminium wiring?

In North American residential construction, aluminum wire was used for wiring entire houses for a short time during a period of high copper prices, mostly 1960 to late 70’s.

Copper and Aluminum should never be connected together. When purchasing replacement receptacles, switches or fixtures make sure that they are compatible for aluminum wiring.

Aluminum wiring is not handyman-friendly, so we at Northumberland Home Values Group always suggest that you have all the work  done by a licensed electrician.

In both cases the buyer can get a quote from the electrical contractor for the cost of repair or replacement of the system and we at Northumberland Home Values Group may be able to negotiate a price adjustment .

The most common type of wiring in modern homes is nonmetallic cable, which consists of two or more individual wires wrapped inside a protective plastic sheeting. Non metallic cable usually contains one or more “hot,  which is current-carrying wires, a neutral wire, and a ground wire, which  must be bare, usually green or green-yellow striped. Hot-active wires may be any other colors except these. However, common practice , as per local electrical inspectors,  is for the first hot (live or active) wire to be black and the second hot to be red.

Nonmetallic cable, individual wires can also be installed inside of a rigid or flexible metal or plastic tubing called conduit. Conduit is sometimes  used where wiring will be exposed and not hidden inside walls, floors, or ceilings.

This is the safest and most modern wiring used today, but the home inspector can check that all receptacles are to code and properly installed.
