It's recommended to inspect your home's electrical wiring every 10 years to identify potential hazards and prevent electrical problems. However, inspections every 5 years may be necessary for older homes with outdated electrical systems. If you notice any signs of faulty wirings, such as flickering lights or burning smells, contact a licensed electrician for an inspection.

As electrical systems age, they become more prone to serious problems such as overheating, short circuits, and electrical discharge (electrical arcs), all of which can put your home at an increased risk of an electrical fire. Furthermore, if your home is several decades old, you could be dealing with outdated knob and tube wiring that, while not inherently unsafe, should still be assessed by a professional. If the wire insulation has worn away over time, or if the installation practices of the time have left you with an unsafe situation, you should have your home rewired without delay.

There are many problems that can be associated with old electrical wiring. In fact, electrical problems are one of the common causes of house fires. Rewiring is one step you can take to prevent these issues from taking place. However, it can be difficult to know what type of electrical occurrences are normal and which are signs that rewiring may be needed.

A few serious signs or causes of wiring problems include:

• Aluminum wiring becoming loose
• Vibrations when turning on appliances
• Circuit breakers frequently tripping
• Loose electrical outlets
• Burning smell from outlets
• Flickering lights when running an appliance
• 40+ years old wiring

The process of rewiring a residential property typically involves an assessment of the existing wiring, planning the new wiring layout, removing old wiring, and installing new wiring. It may also involve upgrading the electrical panel and ensuring compliance with electrical codes. It is best to consult with a licensed electrician to determine the specific requirements for your property.
