"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

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

Professional services ensure safe installations, reliable repairs, and compliance with codes emphasizing safety in electrical networks.

The cost to replace or install an electrical outlet can vary. On average, you can expect to pay between $125 and $215 per outlet, including labor and materials. For a standard 120v outlet, the material cost is typically between $10 and $50. Labor costs for an electrician usually range from $50 to $100 per hour. The total cost can be higher if there are complex electrical issues to resolve. Specialized outlets like GFCI or high-voltage types can cost up to $50 each for the material alone. If you are replacing many outlets throughout your home, the total project cost could be between $900 and $3,000, but you may receive a better per-outlet rate from the electrician.

Yes, many remodels include electrical upgrades for lighting, outlets, or charging stations. Confirm with your contractor.

Basic smart light switches are available for as little as $20. If you can install them yourself, it’s a home upgrade that won’t break the bank. Many homeowners view them as a worthwhile investment for the additional convenience and security they can offer. However, they are a little more tricky to install than standard light switches, so if you don’t have the electrical knowledge to do a DIY job, unless you need a lighting upgrade, remember these are a nice-to-have rather than a necessary purchase.
