"Mario and his crew did an excellent job with my barn wiring and lighting. They took a two or three day job and made it a long single day effort. Their work is clean, measured and professional. The guys are friendly and skilled. Definitely going to have them do some additional work down the road with an RV garage and whole house generator install."

"Chris and Nick did a remarkable job installing our EV charging system. They started the project prior to the arrival of the charger. On top of that my wife and I had a prior commitment and had to leave. Upon our return the entire installation was complete, including charger! Maybe not the cheapest around but certainly the best. They will certainly remain at the top of my list for all things electrical. Dan D."

Small jobs welcome

"Great job mounting my lights. Helped remove an old solid wood 70’s box light. Had some issues getting the living ceiling fan installed. My previous fan had one switch for the fan and one for the light. I guess the wiring is old and incompatible with this new fancy fan. So now one light switch turns the fan and light on and the other switch that controled the old fan does nothing. Thankfully the fan can with a remote control so I use that to turn the fan on and off and it works just fine as a work around. I am very happy with the service provided and will use them again."

Generator Install questions, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

Costs range from $500 to $2,500, depending on generator type and installation complexity.
