Aluminum wiring is one of the most-used wiring types in Katy and other parts of the United States. Since the early 1900s, its light weight, conductivity and affordability have made it an obvious choice for residential wiring. However, disreputable and improper installation techniques can make this kind of wiring a safety hazard.

The Problem With Aluminum Wiring
While aluminum wiring isn't necessarily problematic, it does have some attributes that make it less safe than copper wiring. The first is that it's highly susceptible to thermal expansion. Since electricity produces a degree of heat, and seasonal changes affect temperature, the wire expands and contracts a lot. Over time, this results in loose connections and increased resistance. Aluminum is also prone to oxidation and can cause galvanic corrosion when attached to steel and copper, causing decreased conduction and increased risk of safety hazards.
The U.S. Consumer Product Safety Commission and Franklin Research Institute note that homes wired with aluminum wiring have a higher risk of reaching what they call “fire hazard conditions.” Homes wired this way prior to 1972 have 55 times more potential for this occurrence, and this safety risk often makes aluminum wiring replacement a worthwhile consideration for older homes.
When to Consider Replacing Aluminum Wiring
Not every home in Houston with aluminum wiring has cause for concern. While aluminum isn't as safe as options like copper, you only need to worry about safety concerns if you experience:
- Consistently flickering lights
- Plugs or circuits that don't work
- Unusual static on radios, TVs and computers
- Switches and receptacles that are hot to the touch
- Visible sparks or scorch marks around electrical devices
- Smoke or a burning plastic smell around switches and panels
If you encounter two of these symptoms simultaneously, consider an electrical inspection to keep your family safe. From full electrical inspections to rewiring or repairs, you can rely on Mister Sparky for a high-quality, customer-focused approach to dealing with aluminum wiring in Houston.
