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!

For anyone who is in control, manages, or even owns a facility that has a parking lot for either employees, customers and clients, or both; you know that security and protection of everyone is paramount.

With outdated, inefficient, and low quality output per watt, which is all that matters when it comes to getting the most efficient lighting. The reasons behind this is because let’s say you have two different LEDs products, one outputs 135 lumens per watt while the other is at 120 lumens / watt. To power a light that outputs at 18,000 lumens; the 120 lumen per watt fixture will take 150 watts to reach 18,000 total lumens. While the 135 lumen per watt fixture will only require approximately 133 watts to generate same exact amount of light that the other higher watt fixture products.

See the important of lumens per watt? It’s everything, and we believe

Here’s another project of ours where we retrofitted an existing fixture in a parking lot (before and after):

The image list could go on, but the gist is this: LED has and will always improve your facility’s lot. Just look at the images yourself for the proof!

By choosing LED parking lot products for your facility, you are choosing higher quality along with higher efficiency products. LEDs (more specifically MyLEDLightingGuide’s) offer a better Color Rendering Index rating talked about before is about lumen depreciation. Metal halide and HPS experience greater and quicker depreciation in lumen output than any LED product does. So while a brand new and freshly installed metal halide fixture may look the same as an LED to start off its life; give it a few years and watch the difference. LED is almost guaranteed to be brighter for longer.

On the topic of saving money, how about the final benefit that will make you fall in love with LED technology and what it can do for your business.

While you need to be careful which LED products you purchase and from where you buy them from; commercial LEDs are just as open to rebates as any other.

Something called DesignLights Consortium (DLC for short) qualifies products and lists them on their site if they pass vigorous tests set by them. They offer two types of listing: commercial rebates but they also prove to be lesser of quality. Think; if a company offers quality lights what’s their reason not to get qualified? There isn’t, and that’s exactly our point.

Thankfully there are many DLC qualified products out their on the market, including ours. You can always take a look around just to say hi!

stimulating sensors in the eye that then send signals to our internal clock. It also Nobel Prize in Physics. So how can someone suffering from insomnia enjoy the technology that this marvelous invention forged?

“If you can block blue light, you can actually create something called circadian darkness or virtual darkness” says Researcher Dan Pardi in an Studies have shown that by wearing these amber-tinted glasses, you can produce almost as much melatonin as if it were pitch black, even in a fully lit room or while looking at a bright screen on your tv, phone or tablet.

Electrical work is no joke. If left in the hands of an inexperienced or unqualified electrician, the results can be disastrous. Poor electrical work can leave you at risk of electrocution or electrical fire, and even if these issues don’t occur, it will still lead to ineffective operation. To prevent your breakers from tripping and your lights from flickering, among other things, you’ll want to do your research and make sure that the electrician you hire is the best for the job.
