“Hi. I’m Craig Bryant with Bryant Electric Service, and I’ve been in business in Austin for almost 30 years now. I’ve been asked by many people a lot of different things about electrical work, and so I hope I can help with answering some of your questions as well.

OK. I’ve been asked many times about the difference between aluminum and copper wire, and the biggest difference is that copper is just a lot more stable metal than aluminum. And electricity, the biggest enemy to electricity is heat. The hotter it gets, the more important it is to have a stable metal. Aluminum is good but not as good in that in the long run over many years or decades because the instability of aluminum, when it heats up it contracts and expands. As it cools down, it contracts and heats, it expands.

So that happening over time over years and decades especially at your main service or wall plugs or something then that causes a loose connection and it starts arcing and the arc can create a fire over time. That just doesn’t occur in copper ever if it’s installed properly and it’s real tight at the beginning when it’s installed.

So the other problem with aluminum is oxidation. As they’re both exposed to air, copper oxidizes as you can see when it turns green, but it doesn’t affect the connection of the wire. Whereas aluminum, when it oxidize, it creates this crust that builds on it. And you’ve probably seen it before, but this crust can sometimes get as much as a quarter inch thick. And besides the fact that the metal is not as compatible to the heat and temperature problem. With that crust building up, it will also create a gap between the connections that can cause an arcing.

So copper is always better than aluminum and everything except price. And the main reason that it’s being used is because it’s so much cheaper.”

Older homes have their charm, but as anyone living in one can tell you, they also come with more than their fair share of issues. Building and electrical codes have changed dramatically over the years, and our everyday electrical demands have continued to skyrocket. At Kolb Electric, we don’t want to discourage anyone from living in the home of their dreams.  That said, we do want people to be safe, so if you currently live in or are thinking of moving into an older home, here are some things you should be on the lookout for.

Electrical wires can function for a long time, especially if they haven’t been damaged and if the insulation hasn’t become brittle and flaked off. Even knob and tube wiring, an old standard for wiring that hasn’t been used in years, can still keep the lights on. Age does catch up with wiring eventually, however, and if the insulation fails, by becoming abraded, being chewed, or any number of other reasons, a short or electrical arc could start a fire.

Older homes often have wires surrounded with a spiral metal jacket. Metal-clad wires are still used today, especially in areas where the wire is exposed to potential damage. Armor-clad wires are distinct and do not have a separate ground wire within the metal sleeve, instead using the sleeve itself as the ground. As a result, for fire safety reasons, armor-clad wires are often barred in new construction.

If you can see obvious signs of a problem, including scorch marks on terminals in switches and outlets, missing or damaged insulation or any other signs that look potentially dangerous, you should call Kolb Electric for home rewiring before you expose your home to a live wire.

Restoring old chimneys and relining flues are common expenses of owning an older home. Here’s what happened: as coal started to become readily available, existing homes were retrofitted with central heating systems. Nowadays, most coal-fired systems have been converted or updated for oil or gas, but many are still vented into unlined chimneys. Where chimney liners are present, they are usually made of terra cotta and can rapidly deteriorate with higher-combustion, energy-efficient heating equipment.

When evaluating a heating system, make sure you consider its age, type, condition, and efficiency. For example, an old cast iron boiler may last a century or more, but updating to a more modern system can reduce your future heating and maintenance costs.

Old plumbing systems are notorious for being a mish-mash of old and new materials, especially as additions are added to the home or kitchens and bathrooms are remodeled. Iron and lead piping can become clogged with corrosion and mineral deposits, and typically need to be updated in sections. Cast iron piping is even worse, and can corrode from the inside, becoming thin, pitted, and cracked. Horizontal sections are usually the first to go—especially if chemicals drain cleaners containing sulfuric acid have ever been used.  Unless the home has already had repiping done, you can almost guarantee you’ll need to do it yourself.

Unless your roof is under 80 years old and / or is made of slate, you can bet it’s probably not original to the home. There are numerous types of roofing materials, all with unique life expectancies and maintenance requirements. Many older homes have multiple additions with roofs of different ages and types, so like the plumbing system, individual sections may need to be replaced.

If you’re moving into an older home, make sure you have it inspected thoroughly beforehand to make sure it’s safe. And if you need electrical maintenance in Maryland, Virginia, or Washington, DC, call Kolb Electric today!

Juggling the seemingly endless myriad of accessories, appliances and tools that have become commonplace in modern homes can sure be a hassle. Many homeowners find themselves routinely swapping plugs, or using devices like a power strip. While these can suffice in many situations, and offer a (relatively) effective solution, many make the mistake of relying on a power strip too much.

The only thing Kolb Electric takes more seriously than perfect service is safety! We don’t want to see you caught up in an electrical emergency, and to make sure you don’t we’ve built a short list of power strip safety tips. We also have some alternative, and overall superior, suggestions as well!

When deciding to use a power strip, keep these points in mind:

As we said, power strips are fine. In moderation, and as long as you observe proper power strip safety. But there’s a better solution! You aren’t simply stuck with however many outlets are currently installed in your home. Additional outlets can provide a safe, dependable and long-term solution to your electricity needs! The process is quick and simple in the hands of a professional, and will have you set to handle all of our modern lifestyles.

No matter what you require for your home, the experts at Kolb can provide the electrical access you need! We’ve been handling electricity, wiring and appliances for years, providing our consumers with only the absolute best in service, skill and technology. Contact Kolb today to learn more about our services, or to set an appointment!

The strike doesn’t even have to be a direct hit on your home but can occur within half a mile.  As a matter of fact, the majority of surges that most people take are from problems at someone else’s home or somewhere further down on the power company lines.  A surge doesn’t have to be lightning; it can come from an automobile accident that hits a power pole or even from a routine maintenance on the main power lines when they turn the power back on.  This off and on of the power with the main electrical lines can send surges into your home or business that I have seen destroy lots of electronic equipment and appliances.

Almost every home has multiple computers, and expensive home entertainment systems.  Even our appliances are high-tech with monitors built into the doors of refrigerators and laundry appliances with electronic controls.  These items are especially vulnerable to spikes in your home’s electrical current that may cause melted circuit boards and overheated wires.  Repairs to these expensive gadgets are much more costly than replacing a blown out light bulb or electrical outlet.
