    Question Re-wiring Old House

    We are considering purchase of a 100 year old, two story home that needs all the wiring upgraded. We want to save the original plaster and the wood trim to keep the house's appeal and historic look. Of course we need a contractor but we want to know the possible ways to run new wire without wrecking the house's interior. What about using fiber optic scopes to explore the walls to find passage ways for wiring? Anyone have experience with this type of issue? Thanks

    For a clean job, including a panel upgrade (license required), call for estimates from electricians.

    An electrician will walk around in the attic and crawl space with a powerful flashlight looking for ways to fish wire.

    He may drop a weighted string down a cavity to see how far it will drop.

    Also, remove some switches and receptacles.

    All this will tell you if the walls have insulation, firestops etc.

    If you need a fixed price from an electrician you can point these things out and maybe get a better price.

    Dear J: I think I saw a recent posting here from someone asking about re-wiring -- the price was something like $17,000, so prepare accordingly.

    You really can't put a price tag on safety. Old wirings, faulty wirings, outdated electric main panels, and so on, are the leading causes of house fires.

    Some insurance companies won't even insure homes with inadequate electrical systems.

    Wire the bottom floor from underneath and the upper floor from the attic. If the house is that old the walls should not have insulation. You can also remove all the siding to re-wire, which would give you a chance to insulate and re-plumb.

    We all agree that rewiring an old house should be a priority but inadequate wiring is not the leading cause of residential fires. It is actually 4th on the list and a very small percentage of residential fires. The National Fire Protection Association(NFPA) is and has been the authority on this and every other issue regarding fires and fire protection service for 116 years.


    According to the NFPA the leading causes of residential fires for 2005 to 2009 are as follows;

    Cooking 42%
    Heating 17%
    Intentional 8%
    Elect. Dist 6%

    This ranking did not change in 2010. Other causes such as candles, children playing with fire, smoking etc. ranked further down the list.
