We are a family owned and operated business that has been serving the Baltimore, Washington Metropolitan area since 1925. We are committed to providing superior electrical services. The valuable advantages we can offer you are great service, high quality and experienced workers at a competitive price.
"Do not use this company. They will rip you off. The contract was for eight 300W LED 40 ft pole lights, but I caught them redhanded installing 240W. Who does that? Then, they broke my lock and broke into my sprinkler room which I saw on my video which they admitted. Then, Kolb sued me for not paying the bill which I disputed due to lost tools as result of the break-in. Who does that breaking into a customer's sprinkler room and not informing that they did. I had to catch them on my video. Not only that it took over one year to the work proposed work. TOTAL FRAUD. I will be going to court...."

Hello future friends and clients. I am a commercial and residential electrician with16 years’ of experience. I absolutely love what I do and I am an insured, licensed Electrical Master in MD, VA, and DC. I pride myself on having a company that meets a client’s needs in a timely manner at a reasonable cost. We have become an example of quality work, superb technical skills, and excellent customer service. I am eager to make all your electrical connections and visions come to life. It may sound tempting to DIY electrical work, but it is usually not the safest option. Before you know it you have caused bigger problems that will cost even more money. Let my company do your electrical work safely. Whether you need major renovations, or a simple light change I can help. I am bilingual (Spanish/English). My goal is to make you smile at the completion of every project.
"I just built my house a year ago and needed to add an EV charger to my garage. Trish called me within an hour and set up an appointment for Hugo to come out the next day. There were two additional parts to the job I needed done as well, and one of them was a bit more expensive than I was expecting... but honestly, I had no idea how much to expect for the third part of the job so I can't blame them at all. There was no pressure at all to complete the more expensive portion of the job when I told them I'd have to pass on it at the time. The actual job was scheduled for the following week, and Tommy and Kevin showed up on time and were done in less than 3 hours. They gave me a few recommendations for drywall repair as well since there were three small holes that needed cut to run the new circuit for the EV charger. Highly recommended... Hugo & Kevin were extremely knowledgeable and helpful with all questions from a new homeowner like myself."

FAQs for generator installation projects in Brunswick, MD
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
