Most homeowners don’t give much thought to the wiring behind their walls—until something goes wrong. However, outdated electrical wiring can create real hazards, especially in homes built before the 1980s.
Even if everything seems to be working fine, older systems may not be equipped to handle today’s power demands and safety standards.
If your home is a few decades old, it may be time to take a closer look. Here’s what you should know about the hidden risks of outdated wiring, and how to tell if it’s time for an upgrade with an electrician in Tigard.
4 Problems Caused by Outdated Electrical Wiring
Fire Hazards You Can’t See
A major concern with aging wiring is the increased risk of electrical fires. According to the US Fire Administration, an estimated 23,700 fires happened in the country in 2023.
Over time, insulation deteriorates, wires become brittle, and connections loosen. Homes with aluminum or knob-and-tube wiring, once standard, are particularly vulnerable.
If circuits are overloaded or wires overheat, fires can start behind walls with little warning. Some signs include warm outlets, burning smells, and frequently tripped breakers.
Older Wiring Can’t Keep Up
Modern homes run on much more electricity than they did 40 or 50 years ago. Smart devices, entertainment systems, larger appliances, and upgraded HVAC systems all require more power, and your home’s original wiring may not be up to the task.
When the system can’t handle the demand, it can result in flickering lights, frequent circuit trips, or slow-to-charge electronics.
In some cases, outdated wiring can even damage newer appliances or electronics due to inconsistent voltage or surges.
Shock and Electrocution Risks
As wiring ages and insulation wears down, exposed or improperly grounded wires can create dangerous conditions. This is especially risky in kitchens, bathrooms, and outdoor areas where moisture is present.
If you’re missing GFCI (Ground Fault Circuit Interrupter) outlets in high-risk zones, your wiring may be out of date. These outlets are now standard and play a key role in preventing serious electrical shock.
It Can Affect Your Insurance and Resale Value
Many homeowners are surprised to learn that outdated wiring can impact more than safety; it can affect your insurance coverage and even your home’s value. Some insurers may raise premiums or refuse coverage for homes with knob-and-tube or aluminum wiring.
Likewise, homebuyers often request electrical upgrades during the inspection process. Rewiring may not be the most exciting investment, but it can protect your home, improve energy efficiency, and add resale appeal.
How to Tell If Your Home Needs Rewiring
Not sure where your home stands? Here are some signs that may indicate your wiring is due for a closer look or a full upgrade:
Look out for:
- Frequent tripped breakers or blown fuses
- Flickering or dimming lights
- Warm or buzzing outlets and switches
- Burning smells near outlets or panels
- Two-prong (ungrounded) outlets throughout the home
- Scorched or discolored outlet covers
- Wiring over 30–40 years old with no recent upgrades
- Aluminum wiring (common in homes built in the 60s–70s)
If you’re seeing more than one of these signs, it’s a good idea to schedule an inspection with a licensed electrician.

A-TEMP Heating, Cooling & Electrical came recommended from a friend who is a current inspector. I've used them for years for furnace and AC maintenance. Their customer service is excellent—helpful, friendly, and persistent in scheduling my maintenance. I appreciate that they've never pushed to replace my old furnace but instead helped me decide when to repair or replace without being pushy about sales. Finding trustworthy repair folks is hard, and I highly recommend them. You won't be disappointed.
A-TEMP Heating, Cooling & Electrical goes above and beyond to take care of their customers. I've been a customer for years and am impressed with the technicians and office staff. The fact that this is a family business is also a plus. Thank you.
A-TEMP Heating, Cooling & Electrical did a wonderful job. They were on time, wore shoe coverings, and worked diligently. They replaced our air filter and an electrical part under warranty, explaining everything clearly. The work was clean and professional, and the team was congenial and pleasant.
Everyone we’ve dealt with has been polite, positive, and very courteous. A-TEMP Heating, Cooling & Electrical quickly replaced our furnace during the coldest part of a snowy winter. Other companies couldn’t get out for 1-2 weeks, but A-TEMP assessed it the same day and replaced it in 2 days. Can’t say enough great things about this company!
