Upgrading and Installing Electrical Wiring for an Older Home: Methods of Upgrading Electrical Wiring – When upgrading the electrical wiring of an older home the dwelling space or square footage should be treated as if it were a new home where all of the current electrical codes would apply.
Upgrading Home Electric Wiring
I have gotten quotes to have the entire thing professionally done and it is way out of my price range, plus all the quotes state that the quote does not include repair to walls and ceilings that will damaged as new runs are put in place – we will need to absorb that as well. This has led me to my current plan of having pro’s install service and I will try and do the run’s while maintaining as much of my antique walls and ceiling as possible. Which leads to my question – I have a very open attic, as well as a basement. I am wondering if I cannot have all the upstairs fed from the attic (and a single run from the basement to the attic) and all of the first floor serviced from the basement. Would I need a breaker box in both locations? One up in the attic and one in the basement & should I have the pros set this up at the same time – so that I can then make the runs to the individual rooms from the professionally installed service?
And finally to help save my walls and ceiling (all which are Plaster and lath – with some having an added layer of sheet rock on top – which I have learned is impossible to navigate with original means (stud finders, magnetic cable runners etc.) would it be a horrible or impossible idea to route out a cable path in the lath and plaster and sheet-rock with a router deep enough to house the cable, but not deep enough to penetrate the lath and then just re-plaster over the cable – encasing it in the plaster in the walls?

Methods of Upgrading Electrical Wiring
When upgrading the electrical wiring of an older home the dwelling space or square footage should be treated as if it were a new home where all of the current electrical codes would apply. The project could be done a little at a time, area by area, but it would be best to begin by upgrading the electrical service panel. When dealing with the wall coverings to obtain access to install the new electrical wiring you must consider the time and labor costs to save the existing walls and fish in the wire verses having a crew of laborers remove the existing sheet rock or lath and plaster. Having the walls open enables you or the contractors to have full access to remove all the old electrical wiring and boxes and start fresh with new materials located conveniently and according to code. You will also have the opportunity to inspect the plumbing and any other utilities and the structure and make changes or upgrade as needed.
- David, there are several methods of installing home electrical wiring that can me used, however each method must be done according to code and with a permit and inspections.
- If there are problems concerning access then it is possible to install surface conduit to safely enclose the new electrical wiring.
