"From estimate, to selection of The Juice Company, to scheduling, they made the entire process painless. Had 2 15 amp "peanut" breakers installed to replace an existing breaker and establish a new circuit, and 2 new outlets installed. We also had low voltage network cable roughed in so I could terminate it later, and everything was done not only properly, but quickly. I would definitely recommend them to anyone needing electrical work done in the South Sound region."

"Three electricians worked on the job & completed it in 3 1/2 hours! I was expecting it to be done in 5-6 hours. They even hooked their generator up to my big freezer! The City inspector just checked their work, said it was a job well done! I would definitely hire them again."

"We had In-House Electrical replace/upgrade our main panel as well as setup a generator hook-up and A/C outlet outside. Adam and Avery were phenomenal - they were thorough, kept in constant communication with me during the project to ensure things were being done as I liked, and left the place looking better than when they showed up. They'll be my first call in the future for any electrical work I need done."

"I called Voltlab and Evan Cade to advise me on what to do about some ungrounded outlets in my house. After helpful discussion during a complimentary inspection of the rest of my electrical system it was clear I needed serious attention to more than a few outlets. What I thought would be a simple service call turned into a service upgrade and partial rewire. Though I was surprised with the amount of work required to bring the house up to code, Evan's obvious knowledge and straightforward approach to the work made me comfortable trusting Voltlab and Evan with the project. About 9 days of work was spread over a month from first visit to last inspection and all went smoothly. Evan coordinated scheduling with city officials and inspectors and kept me informed at all times. His crew of electricians did a great job and respected me, my home and property. They are a talented and very experienced team. Evan is rightfully proud of the company he is building. Highly recommended."

Generator Install questions, answered by experts

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.
