"John was always professional and quick to respond and answer my questions. For personal reasons, before hiring Barclay Construction, I had to wait a long time to be able to replace my old siding. John and his crew made it worth the wait. All were pleasant and made me feel they were anxious to please me and take pride in their work. In addition to the siding replacement, they painted the trim and doors and installed my window boxes. I am so happy and appreciative of the great work that they did. I can give them my wholehearted recommendation."

"Kent is an excellent person and I would call him and his co-worker for any electrical work. He installed a standby power generator for me and did an outstanding job. During this COVID-19 period he and his employee wore gloves, masks, and booties when required to be inside our home. Can't say enough good about this company!"

"I had used Worry Free Electric in the past and had very good service. I called James Costello again for some outlet relocations, new outlets, and new light fixtures installation/replacement. I was supplying these new light fixtures. I told James what I wanted to achieve, and where I wanted the new outlets and ceiling lighting fixtures located. He made some recommendations and suggestions, did exactly what I wanted and beyond with the addition of some three way switches for the lighting circuits. The whole experience was above my expectations. James Costello will be my first call for any future licensed Electrician project!"

"Jason and his helper established power to a garage and installed outlets and lights that I supplied. The work was of high quality and to applicable standards. He did not skimp on materials — they were from electrical supply house. I would have liked more communications, but he did what he said he would do."

Generator Install questions, answered by experts

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.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.

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.
