"Bobby showed up on time. Gave me a great price for a new box and new circuit breakers . He started we went skiing, when we returned he was finished and the work site was cleaner than when he arrived. I would recommend Bobby to anyone he is a throw back to when people took pride in their work."

"The amount of work that needed to be done to our 1880 house was extensive. Joe listened to our needs and concerns and offered suggestions that improved our plans. His quote was very fair. He is easy to talk to, professional and honest. Caleb and Dylan who did the work were amazing to deal with. They were very knowledgable, worked hard, and were careful and patient dealing with the oddities of an old house. I highly recommend this company and will call on them for all my electrical needs."

"Installed at a seasonal camp with no roof ridge vents. Upstairs is used occasionally for sleeping and is unfinished, being there is no attic. During the day temperatures easily soar well above 100 degrees, making it impossible to cool with a window unit. Greg suggested putting in an exhaust vent fan on a thermostat to blow the heat outside and create ventilation upstairs. The wiring was quick and the installation smooth. And what a difference! The fan works great and you can feel the cool air flow coming up the stairs if the upstairs windows are closed. This was one of those things we should have done years ago. We're very pleased with the results."

Generator Install questions, answered by experts

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.
