"Pleasure to work with on recessed lighting install. Ken was responsive to questions and time changes via email/phone. We removed the old lighting, did some of the recessed lighting layout, and obtained the materials (he reviewed to make sure it was OK). His installation and electrical work was handled professionally and on schedule. Any adjustments were reviewed with me as a courtesy. We thought the price was fair for the work done. Nice job."

"I required a new water heater installed and Diana builders were able to give me the exact water heater I wanted at the most competitive price. Dave took the time to explain what he thought the best solution was in plain English, gave me a quote a few hours later after researching his exact costs and stuck to his quote."

"Michael, the owner of MNW Construction, was awesome to work with. This bathroom remodel had special circumstances around it for a disabled family member and Mike took all factors into consideration. He listened to our needs, envisioned a functional design, picked out all materials, fixtures, colors, while working well within our set budget. Mike is extremely talented, educated and passionate about his trade and is a hard working business owner. He and his crew are great to work with and take pride in their work. Highly recommend!"

Generator Install FAQs, 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. 

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

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.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

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

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

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

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.
