"Since day one, Deybi and his crew have been able to solve any electrical problems I've had and provide efficient and effective solutions at a proactive level, long term result. First time working with them was due to our previous preferred electrical contractor failing to help with complex electrical problems at a commercial space (office space), so after some looking we found DBG Electric. They were able to help with setting up light switch wiring, installing cubicle receptacles and replacing fluorescent light ballast along with breakers. At another commercial site, we needed help with installation of power packs, emergency lights and flood lights. All of these were installed in a high ceiling area, which was no problem for DBG. They've also helped with lighting a my personal residence, ranging from kitchen light replaced with LEDs to recess lighting needed in the basement. I highly recommend using them, specially with difficult projects that require some ingenuity."

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...."

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
