Medium size Electrical Company based out of Metrowest Area. Currently have 9 licensed employees. Always free estimates. All pricing is based on specific work.

"What I love about VMA is that you can get Residential electrical work quoted 2 ways: Time/Material (emergencies), or they can send a man out and quote the job. You may also take detailed pics, send it in and they can quote it that way. My old electrician they did everything old school w calling, & didn't even like emailing, but not VMA who texts, calls, and emails. 2 professional, Journeymen Electricians did 3 separate days of work last month at my house, from the VMA Residential/Service division. They replaced/installed 7 exterior lights, replaced 2 exterior outlet fixtures with Arlington housed outlet boxes, installed one new Arlington, extended light fixture wiring and 2 doorbell wires, and exchanged a transformer for a larger one, to handle the video loads from Nest and Arlo doorbell cameras. I purchased all the fixtures, & doorbell cams. They supplied the Arlington boxes. The 2 electricians were very efficient, quiet, fast and clean. They made sure fixtures were leveled, and working. One of the 4 glass sides of the exterior light fixture broke cleanly and they honestly brought it to my attention, vs just burrowing it. I just double taped it w clear packing tape, and he put the glass in the rear of the fixture so it wouldn't be seen. I didn't want that to hold up the light install, and will deal w the Amazon merchant I bought light fixtures from afterwards. I had a lot of other construction going on, and the 2 electricians were able to do a lot in the timeframe they had despite all the other noise/work/men around. They fixed cut outlet wires from a bedroom new window installation, moved an outlet 3" to accommodate a stud inserted to shore up the new window. The cut wires were a surprise, and to get the city's Wiring Inspection approved, Cindy the Svc Manager, was very helpful in getting the electricians here stat, & the Building Inspector also stat, who had a 3 wk backlog. I had VMA Electric quote me for a porch and their pricing was much better vs another electrical competitor in Marlborough. The guys are Journeymen level, so aren't outrageously priced like Master Electricians, in the same town, who I had been using. When the Residential side has a lot of work, they can smtms pull guys from the much larger Construction Division. In all, VMA had to come out 3 times, bec the work was staged in between inspections. I love their work and do not hesitate to highly recommend. Just know electricians are expensive, and it cost $2,300 total, up front for all that work. Had I used the Master electricians the bill would've likely been double, as found out they were double/triple charging me the town's Permit fees in addition to double all the same work VMA does."

"With the latest job John and his team completed for us, I am now able to say that for the better part of two decades, the electrical work needs of four generations of my family have been completed by 4th Generation Electric. As John and I were catching up before the install of our transfer switch and generator hook up, he recalled when we first met almost 20 years ago. From that time forward, he and his teams have completed work for my family that spanned from outlet installation and replacement, wiring our full new build construction home, inclusive of aiding with the installation of the power line from the street (which was 700 feet away from the house), outside patio electrical work for an elaborate tiered landscape, generator hook up requirements, among other things. Just as our electrical needs grew over time, and John and 4th Generation Electric have as well, the same level of attention to detail, focus on customer satisfaction, and not only the desire to strive for perfection but the expectation to do so, has been the standard that he knows not only his customers expect but that he expects for himself and his teams. It’s easy to write a review like this when it writes itself. If you have any sort of electrical work needs, big or small, you’d be doing yourself a disservice not asking John for a quote."

Generator installations FAQs

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
