The modern suburban and small town home of today has become an ideal lightning target. The home owner would do well to recognize lightning for the destructive force that it is and protect against this major life and fire hazard. Donohue's Lightning Rods is based in Missouri, near the factory where most of the residential and commercial lightning rod supplies are manufactured. Jim travels regularly to Texas, Louisiana, Arkansas, Missouri, Kansas, Montana, Wyoming, Colorado, and New York. Call today to find out when Jim will be in your area. For installations outside Missouri, Kansas, or Texas, Jim waits until there are a few customers lined up, thus being able to provide the same quality services at affordable prices. **WE DO NOT DO ELECTRICAL SERVICES.** (ONLY LIGHTNING RODS)

"The job was beautifully and professionally done. I have a zero scape yard and the gentleman was concerned about disturbing the gravel when putting the rod into the ground. WOW!!!!"

Generator Install questions, answered by experts

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.

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.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

The cost to install a whole-house generator averages at $5,200, but costs can range from $1,500 to $8,900, depending on the type and size of the generator, and the labor required to install it. To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don’t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.
