Preventive Maintenance

The Spark Shark team can prevent electrical problems before they become problems.

Electrical damage can be unpredictable.

Instead of simply responding to symptoms of electrical failures, our team will take a holistic look at your system and make recommendations to prevent damage from occurring in the first place.

  • You probably know someone who has lost a TV or computer due to a lightning strike or power surge, but did you know virtually all of your appliances are susceptible to damage as well? Whole home surge protection sends excessive voltage into the ground before it can reach your devices, keeping your appliances, electronics, and hardwired smoke detectors safe.

  • The average breaker panel has over sixty wiring connections inside, each one with its own specific torque requirement. Connections that are too loose or too tight can become points of extra resistance that can melt your wires. We use precision tools to ensure that manufacturers' requirements are met perfectly, every time.

  • One of the best investments a homeowner can make is having a professional electrician examine the entirety of the home's wiring to identify code compliance and workmanship issues that can turn into costly repairs.

  • If your electric bill is sky-high and you don't know why, we can install energy monitoring for your whole home to identify short circuits, excessive power usage, and even faulty appliances.

  • Modern technology lets us see what was once invisible. We use infrared imaging to identify hot spots in breaker panels and other electrical equipment to find potential fire hazards early.

I would give them a 10. VERY knowledgeable and professional. I needed a hazard issue looked at asap and he fit me in same day. He also did an inspection to let me know if there were any issues I needed to address. He also answer all of my questions on a couple things I was unsure of. I will definitely recommend him. Also very clean. wore booties and cleaned up the mess. very reasonably priced!

We were extremely impressed with the quality of service we received from SPARKSHARK. The customer service is outstanding as is the work. We had outside light poles installed, garage sconces that needed to be custom mounted and indoor ceiling lights installed. We highly recommend SPARKSHARK for their excellent customer service, their quality of work, their knowledge and expertise and getting the job done right.
