Remodeling electrical in a home is a big undertaking and there are many reasons homeowners need to update. How do you know if you need an electrician to come inspect your home? Is your home older than 40 years? Does it have enough power to supply all of your appliances and electronics? Is your electrical safe? A skilled electrician will be looking for safety issues with your old wiring, determining what can stay and what should go, and working within the limits of closed up walls homeowners may not want opened up. Rewiring a home often requires the electrician to work from the attic since walls won't be opened up. Running new wires through the attic versus an open wall means making sure the new wires are stable and secure by attaching them to attic rafters and feeding them down through the walls from above. In new homes, electrical wiring is secured by stapling the wires to the studs within the walls. This cannot be done in a rewire. Additionally, work must be done in a way to minimally interrupt the lives of the homeowners. You may not need to replace all the wiring, and it will be up to the electrician to decide what can stay and what needs to go. If an electrician discovers your house was wired with aluminum, an inspection will need to be done to see if the wiring is ok to stay. Commonly used in the 1960s and 1970s, aluminum wiring comes loose as the years go on which creates problems such as overheating and can be a fire hazard. Sometimes adding copper connectors at circuit breakers and receptacles is enough to resolve any issues. Other times a complete home rewiring is needed. Do you need more power to run your home? A few decades ago, homes didn't typically need more than 60 amps to run efficiently. These days, some homes need 200 amps or more to run all their appliances, air conditioners and technological gadgets. Increasing power to your home sometimes means rewiring, but not always. Sometimes it's as simple as upgrading your electrical panel.
