"We replaced the original roof on our house. I expressed my concerns about re-installation of the lightening rods to my roofer. We have had at least three direct hits since they were originally installed in 2013. My roofer called William who was very helpful. William offered to come out an make sure everything was 100% after re-installation. He came the day after I called and I'm glad he did. While the reinstall was the best he had seen (his words) there were issues after 5 year and 3 strikes that needed addressed. He fixed those and now I have a new roof and I am certain the lightening rods will work as intended. Highly recommend this company."

"They were fantastic! They were polite, fast, organized, good clean up, and explained everything. The quality of the generator looks durable, and could last longer. They are the only company who told me that the generator needed to be serviced for every 2 years instead of every year. They also installed it on a stoned pad instead of a concrete which saved me a lot of money. The piping inside of the house was a flexible steel coil. They also do service calls."

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!!!!"

"I needed my sump pump replaced, wanted to add a water pressure back up system and had them install a new garbage disposal that I had purchased myself. I had installed our previous disposal myself but I figured they were already coming so I would have them install the new disposal. First of all, the work was excellent. My main problem was with the cost. When I questioned the high rates, $285 to install the disposal and $542 for a new sump pump and installation, I was told that they have pricing set by "job" not by actual time necessary. That was the least expensive model of sump pumps. Another model was $300 more. The backup sump pump would have to be done on another day so it was not even considered at the time, although the prices of the other jobs made me concerned that it was also over priced. Since you are charged a fee for having them show up at the door I decided to have them do the work but I had a feeling the jobs would not take more than an hour. They had two plumbers, one was experienced, and the other one seemed to be learning on the job. Either way, each one was done within an hour. In hindsight I should have trusted my instincts and paid the mandatory "visit" fee and hired another company. If you take the cost of the pump out of the equation I paid $285/hr and $392/hr respectively more than double the highest national average. I will never use this company again because they are taking advantage of people. I would highly recommend that you get some estimates before they show up... don't get charged a flat rate for simple jobs. Don't be afraid to say no and hire another company."

Generator Install questions, answered by experts

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

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. 

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.
