"Lowest price among multiple quotes and significantly more attention to detail and the least visible and least intrusive installation of new wiring from the existing panel. Would definitely recommend and use Mark H. Anderson Electrical Services again!"

Customers say: Quality work

"From start to finish, Long Electric had our backs. We didn't have to hire sub-contractors or to obtain permits -- Long Electric took care of everything. Our go-to person in the main office, Melissa, answered all of our questions and kept us apprised of everything we needed to know. Everyone we had contact with throughout the installation project treated us with the utmost in professionalism. Not only will I call upon them for future electrical needs, I have referred Long Electric to a friend who is also interested in a whole house generator."

"I had a wonderful experience with Electrical Connections. My project ended up being much larger than I anticipated it would be and they were excellent at explaining everything and helping me understand what needed to be done. Customer service was top notch and clearly a priority for everyone I talked to from the scheduler to the owner of the company. Brian was excellent and stayed until the job was done even though it made an extra long day for him. Highly recommended!"

"We had five different things for Lou to fix, including a chandelier that needed to be lowered and made level. Lou rounded the oval links in the chain that held the chandelier and that made it level for the first time! He figured out why a ceiling fan was making noise and why another one wasn’t working at all. He also replaced part of our electric panel which had somehow gotten water inside and was corroded. We didn’t have the right part to change lights in our Faber stove hood, but Lou did, and quickly replaced them for us. We were really pleased with how knowledgeable and competent our electrician was and plan to call him again if we have any more electrical problems."

"I needed a dedicated 20amp circuit and outside outlet installed to my patio. Maitiai arrived on time, was friendly/professional, and completed the agreed upon work. He filed for the appropriate permit with the City of Frederick, and helped schedule the inspection which passed without issue. I would have no hesitation contracting with him again in the future."

Electrical questions, answered by experts

Usually, a light switch goes bad due to normal wear and tear. Light switches are mechanical devices with internal moving parts. These parts make contact with each other, and, over time, the friction can wear them down, causing the switch to feel loose, arc, or fail to operate. 

Grounding is an essential part of installing an electric fence. Without grounding, the electrical circuit will be incomplete. That means the fence won’t work and will fail at delivering shocks upon impact. Even grounding the fence improperly can cause faulty shocks, if any. To ground the fence, you will need to use ground rods, ideally made from copper or galvanized metal, that are at least 4 feet high, for best results.

Pendant lights are very versatile, and you can almost always find one with your preferred style that accepts your preferred bulb. Today, many fixtures use LED bulbs, though it’s still completely possible to find one that uses halogen, fluorescent, or even old-school incandescent bulbs. The manual that comes with your light should tell what types of bulbs you can use with it.

Aluminum wiring can pose a significant fire risk because it tends to expand, contract, and overheat, leading to failing connections and splices. If your home has aluminum wiring, it doesn't always require a complete replacement, but you must take safety precautions. The first step is to hire a licensed electrician to conduct a thorough inspection. Based on their findings, you have several options:

  • Full Replacement: The safest but most expensive solution is to replace all aluminum wiring with copper.

  • Copper Pigtailing: A more budget-friendly option, suitable for certain homes, involves adding a short section of copper wire to the end of each aluminum wire at connection points.

  • Other Safety Upgrades: Your electrician may also recommend installing aluminum-compatible outlets and applying an anti-oxidant paste to connections to prevent corrosion.

Consulting a professional will help you determine the best course of action to ensure your home's wiring meets current safety standards.

By nature, two-prong outlets aren't grounded—but the box they run to might be, which makes them safer. The safest way to test if an outlet is grounded is to purchase a circuit tester, which cost about $20 at home improvement stores. 

If you discover your outlet (or outlets) aren't grounded, know that this greatly increases your risk of personal injury and electrical fires. You may want to consider installing new three-prong ground fault circuit interrupter (GFCI) outlets. On average, the cost to install GFCI outlets is about $210 per outlet.
