You have to be very careful when you're buying a resale home, whether it's nearly new suburban home in a Newport, Virginia planned development or one of those a historic downtown Toronto townhomes they spruce up on TV. You have no way of knowing whether the previous owners looked after anything but the aesthetic appeal of the house. That's why you must insist on having a building inspector come in and tell you what the problems are and whether everything is up to code before you agree to buy. Old copper wiring is a common problem found by building inspectors.
Copper is the typical conductor used in wiring the electrical work in homes. However, copper has been in use for so long that sometimes the system can start to degrade. The problem usually starts with the loss of insulation. The insulation on the wires could be cloth, rubber, or plastic polymers depending on whether it's a new home in Ontario or a very old house. Insulation protects the rest of the house from the current carried by the copper wire.
When insulation starts to come away, you get into a dangerous situation. The electricity carried in the wires must only flow into appliances and materials that were designed to accept it. However, if given the chance, it will flow into other areas of Meadowvale homes that are conductors but are not designed to handle electricity. In cases where electricity is allowed to go where it should not, fires can occur. In fact, one of the most common causes of house fires is faulty wiring.
This is why you should pay such close attention to the state of wiring in your home. Any loss of insulation can be fixed temporarily by applying non-insulating tape (such as electrical tape) but should really be replaced. In a case of some wires in the house losing insulation you can bet that the rest of the Lagrange NY homes built around the same time are suffering similarly. Because of this if you find electrical problems somewhere in the house the chances are good the problem persists throughout. In this case the entire home will have to be rewired.
In order to rewire a home completely, the interior walls have to be ripped out, which, as you can imagine, amounts to significant costs. Some smaller Toronto condominiums could be rewired with only a few hundred or a thousand but most detached houses will cost thousands of dollars to rewire. If you're still in the offer stage, try to get the current owner to foot as much of the bill as possible. If not, it is possible for a DIY-er to handle a rewire section by section but only if they're very knowledgeable and confident.
